Unreal Engine 5 Beginner Tutorial - Creating your First Game with Blueprints

Do you want to create games in Unreal  Engine but don't know exactly how to start?   Here we will create a 3d platformer game  while learning how to use blueprints   to create the mechanics. Also, we will reach a  gameplay flow for our game in a matter of minutes   so we can test the game very frequently and  build on top of it. There are no requirements   for this tutorial, but knowing your way  around the viewport will make development   faster. When you finish these tutorials, you  should be more comfortable with blueprints,   and also have a good idea on what it takes  to develop a game. And before I forget,   if you want to support us in any way, be sure to  check out our store. We have a lot of cool stuff   like a free blueprints course, another to model a  castle inside unreal, and our marketplace assets   that were made with care and effort. If you want  to learn more, you can consider becoming a member   of our channel, where you will get exclusive  tutorials that can take your game development   skills to the next level. Let's start by creating  the project, be sure to choose unreal engine 5 and in the project browser, we will create a  blank project. We will be starting this project   from zero, so i don't need to update the tutorial.  It happened to me before, that I used a template,   and that template changed so I want to avoid that.   So let's just create a blank project,  blueprints is fine, and let's call it my 3d platformer and create. Now that the project loaded, let's, let me  put dismiss, update the file. If I press play,   I shouldn't have anything here, only this  example map, and now what I'm gonna do is   import the needed assets that we will use  in this tutorial. These assets are free   and you can find it in the marketplace. Here  in the unreal marketplace, if you search for   hour of code you, will find this project. It will  say that it's for 4.26 doesn't matter, just create   it, and we will use this content. Whenever you  create the project you need to find where usually   you store your projects. In my case this folder  is called unreal projects and it's in documents   and it should be under unreal engine hour  of code. What we need to do here is just,   open the content folder search for hour of code  and teachers marketplace. We will copy this, copy and we will paste it in our project.   Here content right click it, show  in explorer, and paste it here. This will probably break some stuff  needed, but I only wanted the assets. Here I'll press import just in case, and  you will see that this has some blueprints   inside it and some maps but we won't really  be using them, we just need the assets.   Architecture, there's some roofs, and we  will see how we're gonna use all these assets   but for now that's what I needed  to get before starting development. Now we will create the character  this is a key element in any game. So let's first create a folder for our project and here should be three i'm just creating  a folder with the same name of my project so   I know where I'm putting all of my assets. Here  because the character is a core feature of our   project without it, we won't have any game.  So I'm gonna create a core folder and then   here I'll create a folder that will be used  for anything that the player needs to have. Now to create a character, we  just need a blueprint class   and here, in the common section we will  select character. This is a blueprint class   that will be useful for any type of biped  character. I'm going to call it main character. This class already comes  with some capsule component,   a narrow component to know where  we are facing, and then a mesh, a skeletal mesh. Yeah. This will be the  representation of our character inside the game. And, it also has this character movement, where we  can tweak how our character will move, and before   I mention that this is used for biped characters  because they already have, for example, swimming,   walking, falling, flying, etc... but  it's especially for bipeds because   we have a capsule component that if we have  for example, a horse here, it won't fit. So if   i needed to make a playable horse it  will probably be a pawn, not a character.   So just take that in consideration. For this  example, this character blueprint is just fine.   We need a visual representation of the character  and we just need to go to the mesh component,   let's change this skeletal mesh, here in the  details panel, and select the epic character rig.   This is the asset that we imported from  the other files and, if you open any of   these files, there will probably be errors  so just ignore them or just don't open them.   Now we just need to bring it down a little bit and rotate it to be looking forwards.  In Unreal when whenever I say forward   or when whenever someone else  says forward it means X positive   and well Z, is how high or low something is the  vertical value so it changes from engine to engine.   Just keep in mind here in real Z is the  vertical value and X positive is forward. Let's adjust this capsule component a little bit,  so it matches better my character, so the radius   and also the half height,  maybe a hundred should be fine, and the radius 40. Now if i press play here, we will see that nothing changes. We need to tell  our game that we want to use this character.   So let's create what it's called a game mode,   right click here let's create a  new folder called framework,   and the game mode is part of the Unreal gameplay  framework. Let's just create a blueprint class   here we will have the game mode. These common  classes are all part of the gameplay framework   and the game mode, specifically, is in charge  of defining the default values of our games   and also the rules of the games, especially rules  that have to do with the state of the game like   losing, winning, starting etc. and I'm also going  to call it GM from game mode and My 3d platformer. Now let's open it and we will go to the details  panel or the class defaults, if you don't have   it, just press on class default, and you will  have these settings. Here I need to assign the   default pawn class. This is the character  that will be used by default, so here I'm   gonna select my main character. Let's compile,  if we still press play it's it will still be   not using the character, so let's  go to the project settings,   Edit -> project settings or here in settings ->  project settings. We will go to maps and modes   and we will define the default gamemode. Let's  use my GM_My3Dplatformer. So with this in place,   in any map that doesn't have a game mode, it  will use my character and right now I have this   kind of first person character but we  can see that it's already in the game. Now that we have this character when we press  play, we need to talk about a little bit the three   elements for any type of gameplay. This is the  character, the camera, and the controls. The   character is how the player will  represent itself in the game,   in this case this is my character and  this is how i see i'll see myself.   Now I need some perspective like the camera if  i want to do a platformer like we're gonna do,   a third person camera will be fine, a strategy  game would probably use a top-down camera, action   game probably a first-person camera like this  one. So you need to define the camera somewhere.   And then we will define the controls that are the  third key element. So let's start by the camera.   Let's open my blueprint character, we  don't really need the game mode anymore,   for now, and here in the main character i need  to define a camera. We can add a camera here and this will make a floating camera. Because i know that later i will want  to check the conditions so if i have a wall here i don't want the  camera to clip inside it. It will be better if i create a component  called spring arm, and it will serve as an arm   to put the camera in. So here i created under  the camera, i really don't want it to be   this way so i just delete it select the root  component capsule component and create it again. So now i have this spring arm  i'll put the camera inside it,   and this is just attaching the components.   Now you will see my camera is here and it's  good to reset any transformation i did to this   camera so i'll reset it here, location. And it  should be every value in zero this will allow us   to see how this spring arm is working, and if  we want to change the target arm length it will   affect our camera. So, if i press play now, i  will see the perspective of the camera, and also   I can change this and it will be affected in  our gameplay, for now maybe 600 should be fine. So now with the character and the camera we need  to define the controls, so we can move around   our character. To define the inputs of  how we're gonna control this character,   we will go again to the project settings,  here I did project settings also,   and we will find the category called inputs.  here in inputs we will have action mappings   and axis mappings. Axis mappings are  inputs here it is, that will receive a   value between, well, usually between zero,  well, minus zero, minus one excuse me,   and one. So if I wanted to, for example, is  used for the movement let's add move forward. And, I could select here the key or if I'm using  a gamepad, the input for the gamepad or also   I can press here and press the key I want to use.  So in this case move forward W sends a value of   1. It's not really necessary to create  another one called move backwards, excuse me. Or something like this. It's not necessary  because here it moves forward, I could put   another input like I just did by accident. Here  another input press S and this will be a scale   -1. Well, the same thing  I'm gonna do for move right. And this will be D, scale one,  and S, A, excuse me, value -1.   Now these are axis mappings and they usually  work really well with the gamepad, because if I   add for example here, the gamepad usually here is  the thumbstick in y, move forward. This will give   me a scalar, so if I'm just moving the joystick  a little bit it will give me 0.2 0.3 etc so we   can make the character work. And, here move  right, usually is gamepad left, where is it? X. Now the action mappings are different and are  a little bit more simple. Oh, and I created two,   excuse me. It's usually just a key that will be  pressed and released so for a specific actions   that have a clear start and an end they  work really well. For example, the jump, jumping, we can add here the space bar or maybe  in terms of gamepad, it's usually the face bottom and button bottom, yeah. This is in, should be a  or b depending on which type of gamepad you have.   And with these inputs created, we can go back to  our main character let's go to the event graph,   and here in the event graph we will create any  functionality or interaction that our character   will have. Let's create a simple jump for example.  So, let's just right click and press the jump,   well type jump you will have a lot of jumps  and this has to do with the blueprint we're   using that is a character blueprint. But what  we want is the input, input, action event, jump.   This will have the name that we assign it so   if you change this name you should reflect it  here so jump getting a jump to work is really   easy if we're using this kind of character class  because we can just press, call jump, and when   we release the character, excuse me, the key  in this case space bar, we will stop jumping. Now if we press play we still can't move but  we can press space bar and our character jumps. With our character jumping, it's time  to add the movement, so let's go back to   the main character blueprint and let's save it. Be  sure to periodically save everything. And now we   need the move forward event and the move right. We  will create a simple way of making this work move   forward and then we will explain in more detail so  here's move forward and also here is move right. Our character already comes  with a way of adding input, and we can use that node by right  clicking and add movement input. We just need to connect it and if I, for example,  move forward, we said that x positive was forward,   let's just put one, and if I press play we will  see that with this scale value I will go forward   automatically. If I connect the axis value of  this move forward, right now the axis value   is zero because i'm not pressing W. If I press W  I'll move forward if I press S I'll move backward.   The same thing can be done with the move  right and let's just change it. For example,   the scale value should be axis and here  instead of X, X will be zero and Y will be one. Let's press play, and now I do have this kind of  movement. We also need to know that our character   should be able to move the camera around and  that thing will cause a little bit of problems   with this type of implementation, but we will see  it along the way. Let's add the camera movement. Here axis mapping, I'm just gonna call it turn.  Usually is when you're moving your camera from   left to right and here I'm  gonna select Mouse, Mouse X   and well because I'm already adding the controller  support we can add gamepad and it will be right   thumbstick X. Then we will add another axis  mapping and this will be called look up. Here it's Mouse Y and you  could also add the gamepad right thumbstick. So remember  that maybe the gamepad is not   translating exactly with the mouse  movement you can create another input   specifically for the gamepad so you can change the  scales or maybe the way you handle the movement.   For now this is more than enough  for this example, so let's use this. Let's create the action event called turn, axis event  excuse me, and then the event called look up. Here it is. And here we can add some Yaw.  Add controller yaw input, we are gonna connect it like this, and  this one should be add controller pitch   input. If you don't know what yaw, pitch, roll  is, whenever we have a camera and hopefully   I can add the camera really fast here, this  camera will be fine. Whenever we have a camera,   if our camera is rotating this way it's called  yaw, if our camera is rotating up and down   it's called pitch, and if our camera is  rotating on its sides like this it's called   roll. So that's why here turning should change  the yaw and look up should change the pitch. If I press play now with my mouse, I can  turn around and right now I can't look up   or down. But let's see what happens  with my controls. Now if I press W, we are still going to the same direction.   Why is that happening? Because we are  only adding movement in the X value,   so we need to change the way we are adding  this movement and that's what gonna do next. Let's fix first the camera rotation because i only  can move my camera in this axis but not in the   y-axis and if we see these events, we can see the  mention of the controller. Controller yaw input,   controller pitch input. Controllers are a  class that will possess our character so,   If I press play, this is just a character and  if I add another character to the map here, let's just add another main character,  you can open this by using ctrl + P   and here main character. So I now have two characters but i'm not  controlling one of them, this is because   the way that inputs are sent is by a class called  controller. In our case, the player controller.   So a player controller will be a class, a  blueprint, that we are not seeing but we are   constantly interacting with it and this class is  sending the inputs to any pawn or character that   we tell it to control or in this case, in unreal  is called possess. So if my player controller is   possessing this character then, whenever I  press W it will move, make it move forward.   But, because I'm not possessing this one, nothing  is happening, happening to this character.   In Unreal we can unpossess and then possess  another character again, is just a way of   changing what we're controlling, but in this  case we are adding the rotation to the controller   so we need to use that rotation in order to  move the camera. So here in the spring arm,   that is this component, we will go here in  camera settings and use pawn control rotation.   This refers to the controller that we were  talking about, and we would press true. Now let's press play, and we can move it side  to side, but also up and down. Now, for my taste   I find that, that the y-axis should be inverted  for me to be comfortable, so you can either do it   here by, look up multiplying it by minus  1, no, not minus 10, that's too much, -1. Play and it will be inverted, or you  can also, if you want to keep it clean .  You can also, here in lookup just put  -1 and then it will also be inverted. Okay so with the camera working we  can then make this movement work. Now to fix the movement, I would need  to know where my camera is facing   and not where our character is  facing. Why not use our character?   Because it will probably look a lot  better if here we go to class defaults,   and in pawn, let's uncheck use controller rotation  yaw. Now if I press play we can look around our   character and our character is not using the  controller rotation, but this will mean that   if i'm moving, want to move forward like this,  instead of using where our character is looking   like this we want to know where our camera is  looking forward. That will be this direction.   So to get that direction we will  first make a little bit of space,   a little bit, and just like we added some  controller input we can get that control rotation. With this value, I can know where my  character is looking. Now this is a rotation,   a rotator excuse me, and we need a vector for the  direction. We can ask here, get control rotation,   I want the forward vector for my forward  movement and I want the right vector for my move right. Now I could connect it like  this, and it would work If I press W and I keep pressing  W, it will move forward, right? And every time I move right doesn't matter  where my camera is looking to, it will be   still moving right, and in order to show it  better, I can go here in my character movement. I can go to character movement, rotation settings,  and here I will use orient rotation to movement.   Just check this and press play and our character  will rotate towards the movement and that looks   a lot better actually but we need to do a  little transformation to these vectors because   in the case that our character could move in the Z  vector, this is giving me a vector that also moves   in the z-axis. How can we see this value? We  can use this useful node called print string   and just connect our vector to it. Let's press  play here we see the rotation value if we   move our camera, then I'm seeing that Z value  change, and I really don't want it because   it can give us some problems later on, so that's  why i'm gonna just delete it. Here in the world   direction I'm gonna drag it out  and press make, make a vector, and this one I will split it. I saw that Ii don't  need the Z value, so i just need the x and y value   so our movement is always parallel with the  ground floor, and I will do the same with this world direction. Split and x and y, and now  if I connect this vector to this print string   then i only gonna get the x and y  values and this should be working fine. now let's just delete this print string  and we have this um movement working just   because of organization's sake i i like it if  i have a little bit of freedom with this and   also usually stacks things like this  this so it's easier to show more code something like this yeah and it's a little bit more compact and  it's also a good practice to select the notes   and make some comments here for example  select everything press the letter c   and just type movement input and here below  just c again mouse oh well camera camera input and now everything is good and tidy now that  we have a character that can move around   and jump around it will be a good idea to  have a level to test it and change some values   so here i'm gonna create a new level new  level let's just use empty open world   because it brings some good optimizations  and we have the word partition and we will   also be able to use one file per actor that we  can explain what it is a lot later but for now   these words should be enough for us especially if  you're gonna be working with other developers but   if you're not then you can just new level  an empty level let's make it nice by   adding a directional light and it will be good to  have some something to see for example this cube let's just put it in the zero zero and  stretch it a little bit we will change this eventually now if i press play i won't see  anything because there is no light here   so i need to add first my light directional light it will be good also to add some  visual effects here sky atmosphere   so we have some sky to get rid of this  black void we can also add visual effects   and an exponential height fault that's a  lot better if we wanted clouds we can add   visual effects volumetric clouds so now it looks  a lot more nicer with this type of lightning objects it will be good to have a space for  them and here i'm gonna put them in minus 400 and 400 and i will copy this value i will  paste it in another one and just add it 100 and i will do the same for the  rest of them i just want to to know that oops ah 600 was too much paste it again i just want to know that if i have   if i found one of these in the  map the other ones are near there it is and this one the  same paste it and now it will be   balanced 300 also just click on the four of  them and let's create them their own folder   here like right click it move it create  new folder and let's just call it lighting yes so it's easier to search for them and well  if i wanted to disable all of them we can do it   perfect now this cube like really doesn't  reflect our cheerful character so what we're   gonna do is just replace it we're gonna  search for any asset that we can use here   content and because i don't really remember where  our assets are we can just use a filter inside the   content browser or well content drawer filter  let's just search for an static mesh and here   it will show us any static mesh inside the folder  that i choose so here it will change depending on   which folder or i can just search in all the  project and we should have floated island m   should be fine i believe yeah that that  should be good so let's just drag and drop it   maybe it's really too big uh for now should  be fine let's just put it on the zero zero and if we press play we are  spotting wherever our camera is   we need to define a point where to spawn  our character so we will use this player   here in basic player start you can also just  type here click player start and you can   find it this player start will will define the  location and rotation of our character so we can   put it like here it doesn't matter where our  camera is let's press play and it will start there great now we can add some assets and tweak the behavior  of this character that it now can jumps but we   should really tell it how high it should jump  so for example here i see i saw some crates and maybe it's it's too large right if there isn't another one smaller than let's just reduce its value let's scale it to maybe this size 0.5 like half of the value yeah  that should be fine i should be able to jump this   and oh is in case i just jumped the gun you can  move rotate and scale and change this widget   by using these buttons or by using the hotkeys  here w e and r so now let's change how much this   character jumps i will go to my main character and  the everything related to the movement behavior of   this character will be with the character movement  let's click on the character movement and also   the search for the jump jumping and falling  here i want to jump twice as high let's just put   multiply by two let's press play and  now i am jumping twice as high but let's   take in consideration that it is a  platformer so you really need to be very very precise on your jumping so we will go  back to the jumping event input action jump   we had jump and stop jumping why did we put stop  jumping because inside this character and let me   just return this value this jumping value to the  one before i had you can also search here jump   and i'm gonna return it to the default volume so  this stop jumping is here because this character   has already functionality related to jump we can  go here to the class defaults and we have jab   jump max count and also jump max hold time if you  needed a double jump you can put here 2 press play   and now we have a double jump or triple jump just  put here three press play and triple jump we have now for for now i only want one jump but i  will tweak this value called max hold time   and this allows us for example if i put one that  whenever i press play and i press the space bar   and just release it immediately i do a small  jump but if i hold it it will do a bigger jump so it's it's pretty nice right   now i don't really want to hold the space bar like  one second i only need to hold it for example 0.2 0.2 oh that's the max count  excuse me 0.2 let's test it and a little jump would be this one max jump  would be that one right so now i can tweak   the jumping velocity maybe 600 should be fine that's a little jump and a max jump should be this one so maybe 0.3 could be  the value that i'm looking for because i want to with a  little jump reach this value   this box and with a holded jump i  should be able to reach two stack boxes like this and i don't seem to reach so let's  just increase that that hold time maybe 0.4 almost there and 0.5 who it's  a character that can jump a lot okay that should be fine now with this knowledge we also should  be able to change how fast it should fall   right now it's too floaty for me maybe we can  up the gravity scale maybe two or two three and that feels a lot better for me actually am i still able to reach there no but maybe it's  better it was jumping too much for me i believe   yeah yeah it's jumping too much i i  didn't really like it that much so let's what happened here oh simulation 0.3  was fine and here max jump one is fine   let's just add some jumping or  well let's just test it like this   this is a little jump a bigger jump  should let me reach it yeah it's it's fine just a little bit of jumping to tweak  it better where's my jumping here it is   50 should make the difference and now yeah  that's a lot better a lot better if we wanted   to change the movement speed we can also do  it here in the character movement we can go to   walking and here max walk speed we can  change it maybe to be a little bit faster 80 and now i'm liking it even more now it's looking  pretty good well it's feeling pretty good   our character feels pretty good  our camera feels also pretty good   and the controls are what any player would expect so yeah that's great the last thing we would  need to do with this character is to make it   move it's really not appealing if our character  is just sliding around so we're gonna do just that   now and also you can tweak the movement of the  character to your liking maybe you don't want it   to jump like this it's fine it's your game after  all so let's make it move around we we will see   here we will click on the character press f just  to center it and we will find the skeletal mesh   here we can also define the animations and  if we define for example here animation mode   asset we can define any asset that  exists for example here should be   i don't know idle but this will mean that when we  press play it will be stuck in that animation so   what we need to do is use an animation blueprint  so let's select the skeletal mesh component   here animation blueprint and right now we don't  have an animation blueprint that works for us   this one is probably broken so we also want  to create one from scratch just to not depend   on anyone else okay so because it will have to  do with this character let me remove this filter   let's go to my 3d platformer folder and  let's just call it this folder characters   just in case i have more characters and folder   how this one is called epic character  so let's call it epic character let's right click animation and animation  blueprint we already have done let's select   this specific skeleton epic character rig skeleton  and create let's just call it animation blueprint   epic character and let's open it like i was  saying we already have done a video on the   animation blueprints so i'm not gonna cover the  fundamentals here so you will just need to copy   what i'm doing here okay so we need a way to  define the states of the animation of this   character let's just right click here in the anime  graph you don't have it you can find it here here   is also the event graph so here in the anime graph  let's just right click and create a state machine let's just put a state machine and it was add new state machine  let's just call it locomotion because it will be the any motions that will  have my car that will drive my character and   i'm gonna connect the result here let's  just double click this state machine   and let's create an idle state well let's create  a state first add state and we're gonna call it idle movement oh i'll i'll run it let's just open it and we will have to use this  there should be a blend space here either run   let's just add it here let's connect it like  this and this speed let's put it as a variable   now let's compile it so the variable exists  and we will go to the event graph here   i'm just gonna ask for my character let's  just cast to a character this is just   making sure that this owner is a character if  it isn't our character will just slide around   but if it is i want to know one the speed and  we can also get the speed from here just get velocity and ask for the length and that is the speed i'm gonna put this here just in case   split let's set it up because i'm gonna need  it when i'm jumping set the speed like this let's save this to compile it now if i go to  this tab the animation preview editing values   edit preview we can change the  speed and it should reflect   the value but right now i'm driving  this value from the blueprint let's just oops let's just remove that pin right now and   just move it around to see if my  blend space is working it is working so speed let's just connect it like this  compile it let's go back to my blueprint   main character and here in animation well select  the character mesh select animation and in class   let's look for our animation blueprint and when  we press play now it should be moving around great now but if we jump it's still doing this so  it's not really working for us let me see if   this character has a jump animation it should have   whenever we open an animation blueprint we can  check the skeleton of the mesh that we are using   the skeletal mesh the skeleton skeletal mesh and  the animations so here i will search for a jump   and we have a lot of them jump run   jump end loop start jump up we're  just gonna use this run and end so let's go back to our animation blueprint   let's here in the idle running we can return to  the state machine like this by using these crumbs   and let's create another state  let's put jump start jump loop and jump in and we're gonna connect this jump end back  to the idle running something like this   now these are different states let's just fill  the states with animations here i'm gonna search   jump and i'm gonna see if this jump  loop does this works should work good enough and what's this run loop   i i believe it's the same so  let's just use the jump animations there's here uh this one doesn't doesn't have too much   personality to them so i'm  just gonna use the jump up for the jump start in the jump loop i will use a jump up loop and connect it oh jump up is the whole animation oh  excuse me then jump loop is correct   here jump loop is the jump loop in jump start  it will be the jump up start yeah this one let me replace this jump up with the jump start and in the jump end we will use the jump up end now we need to end if we press compile it  will show us some error because we are not   entering these states there's no way for us to  enter this and these are the transitions rules   so for example if i want to go  from idle running to jump start   probably i want to know if the player is  in the air so i'm gonna promote this to   a variable and i'm gonna call it is in the  air or maybe is falling so if it's in here or let's just call it is falling is in  there falling yeah let's call it this fall and now in the event graph we need to set up that   value called is falling it's falling it  is falling or upset is falling excuse me and the character does have a way of  knowing that so we can ask is ollie and we can connect this directly that's  why i needed this cast to the character   now whenever this animation ends i don't want it  to loop i just want it to play once and then go to   the loop one so let's here in the jump start  click it in the detail panel loop animation   and check it so when this end i wanted to  reproduce well to play this jump loop so here   in the transition i'm gonna ask jump start this is  the state so i'm want to know the remaining time   can use the fraction you can just use the  time whatever you need so jump start here   i'm gonna ask if it's less or equal than zero  this will mean that the animation finished then it would play the jump loop and  i do want this animation to loop so   this is fine and whenever i touch the  ground here so i'm not longer falling not boolean falling so if i'm not falling then i  will play this jump end i do not want this to loop   and the transition to the next state will  be when this animation ends so i'm gonna do   exactly the same as the other transition rule  so get an in time remaining if it's less equal   than zero then it will enter the next  transition and i will put put it like this   the difference between this and the time  remaining and the fraction remaining is that   the fraction will give you a value  between zero and one and this one will be   between 0 and whatever the length of the animation   is so now let's compile save it press play and i  can move around if i jump my animation will work great now keep in mind i have skipped some  explanations for example what is a blend space   what is a state machine we go in detail with  these topics in our animation blueprint tutorial   it's a little bit updated because unreal engine  5 released but the fundamentals are still there   now with that out of the way with the animations  out of the way let's just close everything related   to that and let's save my main character and  also let's save this map file save current level   let me add my 3d platformer and if you are losing  track of your folder you can right click it   well we can change the color we will see it after  we save this so let's create a folder called maps and here i'm gonna put character test map let's just save it and like i was saying i lose track  of my main folder constantly so let's   just set the color i will set it to a blue  let's put it okay and now we can find it easily   maybe blue doesn't pop up that much we  can change it to any color you would like and with all of these out of the way we can start  creating mechanics suitable to the platformer   genre for example pickups it will  be very probable that you will   play around collecting stuff maybe coins  is whatever we need in order for my my game to have some sense of progression right  so i'm gonna create a pickup now let's create first a folder inside the core because  if our game doesn't have pickups then   i will probably won't be able to win okay  so let's just click a folder here and call it pickup open it create a blueprint class let's just  create an actor call it blueprint pick up double click it create a static mesh and  it will be blank so select the component   search for this there should be a  coin or something that we can pick up   here of all the assets collectible yeah let's  use this one for now so we have this collectible and now if we can bring it to the map  it can be like this let's press play and nothing is happening right so what we  need to do is some interaction we want to   collide with this pickup so let's click on  the root component add a sphere collision   and let's call it pick up collision and i'm gonna maybe 60 would that be too much that should be fine i'm  gonna set it to only collide with my character   and this will be here in the  collision category collision presets   overlap only pawn a character is a type of pawn  so this will work for us overlap on the pawn   and whatever it is overlapped here if i go to the  events category at the end we have an event called   component begin overlap let's click it   and for now let's just compile save it and  if something overlaps it especially well if a   pawn overlaps it we will just destroy this pickup  compile save let's press play and if i overlap it   then it gets destroyed and it looks like i  pick it up right so that pickup is working   fine for now with the pickup created we can start  duplicating this one by holding alt and dragging   the blueprint and if we hold alt and shift  we can also move the camera so we can have   a lot of pickups around the map and i'm not liking  these hard shadows so let's add in it was it light   skylight and drag it here so we can smooth those  shadows and i'm gonna add it to my group of of lighting actors let's just copy that paste it here at 100 and add it to the folder that already exists  lighting okay that's better that's a lot better   actually and we were talking about at the start  to that is important to have the flow of the game   as fast as we can so having this in mind right now  we just have the movement the camera the controls   and we have something to do  which is pick up this step   if we wanted to have an ending to the  game we would probably need a goal so in order for us to have this goal we need probably  to reach somewhere and whenever we reach that   place then the game will end like or well the  level will be beaten so let's create that goal now let me search for a good mesh for the goal   it could be a kind of door this one this  should should be good yeah yeah that that   seems really nice actually so let's use this  door this door this wall yep let's use this   so let's create the gold blueprint in the  core folder and let me remove that filter   because also if the goal doesn't exist then what's  the point of the game right so new folder goal blueprint class actor because i just  want a blueprint to put inside the map and here i will call it blueprint gold i need some something to  represent it so let's add a static mesh component find that door wall door or just door door does  this works nope that's not it door kit what this one and i'm gonna put it in the middle someplace like that x positive  is the forward so let's   ctrl c and rotate rotated first  and then move it to almost   the middle that's fine we also need a way  to interact with it so we will also create a box collision it will be pretty similar  to the pickup so this one will be and   i don't want the box to be  attached to this static mesh   so i'm gonna drag and drop it on top so i can  detach it this box i'm gonna reset its values   and now i'm gonna increase the extent maybe 100  here should be 800 almost yeah that's fine and 200   and i'm gonna elevate this component  like this so whenever i touch this i win   now i also need to change the collisions i don't  want to overlap all dynamic objects i only need   the phone on and here begin overlap for now i'm  just gonna show a message print string saying that you won let's save it compile it and i'm gonna put that  goal in my level and now i can do some stuff here   pick up some stuff and then go to the goal  and it will say that i won i need this to be   in a place where it is difficult to reach but that  will be whenever we create the map for the game   with the goal and the pickups we have already a  simple game flow to make it a little more official   we can go to the game game mode framework  game mode we can open full blueprint editor   here custom event to create something  that will trigger whenever we tell it to   and we're gonna call it win the game  or pass the level just win the game now with this i'm just gonna copy and paste  whatever we have here i just cut it paste it here   you won and the gold the only  thing that it needs to do it's get   the game mode and ask if it is using my gm   my 3d platformer game mode and tell it  that yeah win the game this will allow us   that if for whatever reason we don't want to win  by the goal anymore we just need to delete this   and if whatever it happens after i win we can  change it in the game mode and any object that   tells the game that we already win  will execute whatever code we have here   so it's a more clean way to manage our game  flow and why did we want to have a game flow   so fast because now we can see if the game is  working we can start tweaking the values maybe   these jump values are weird or the animations not  working or maybe it's too simple the game just you   just walk here but these are decisions that can't  be made now we can start testing any mechanic   that we had in paper and just adding it  to a working game will give you a better   perspective so for example right now my game is  very boring because it's just a plain surface   so we would need to add some difficulties  some obstacles for example here we could have a static mesh already have it  here floating iceland maybe s which one is smaller they are the  same size so let's just use this one let's put it a little bit more small and i'm gonna put it like this and another one here and i'm gonna rotate it so it doesn't look like  it's the same and i'm gonna put the gold there   and i don't need a copy of it i just want to  move it with shift so my camera also moves   and i'm gonna press end so it snaps to my  floor now if i test the game i can pick up   the coins and we really need to do some  overhauling some overhaul there so it it   works better and now i can see that i won also  i can change something that is really bugging me   is those animations i don't really like  them that much so i'm gonna go to player no   excuse me characters epic character animation  blueprint jumpstart will be the running one jump run start i'm not gonna delete this for now  in ch in in case i change opinion jump loop   will we the jump run loop and the jump end will be the run no not the run  start the run end let's save it compile it play it oh and this is oh this is not working  properly because the end is looping   and also i should remove the jump start loop  so now it's a lot better i like this a lot more yeah perfect now no it's it's better with that animation polished let's save it here we should do something about these pickups  why because there probably will be more than one   type of pickup pickups is one of the most common  elements in any platformer game so probably we   will have coins keys power ups etc so in order to  create another pickup we could just copy and paste   this code but whenever we need to make a  change then it will be really difficult to   keep track on which pickups have the change or  fix in the code and it will be a mess if you have   more than one or two so we can use a concept of  programming which it's called inheritance this   will mean that for example my blueprint pickup i  can right click it and create a child blueprint   and this child will inherit all the traits of  the parent this one i can call it blueprint coin and this blueprint coin let's  just drag and drop it here play it and it will work exactly as the parent if i needed another type of pickup for  example pick up another child blueprint e i can move it here but this  doesn't look like a key right we can make this change if we right click it  edit it or here double click it and in the   static mage change the static mesh i will change  it there should be a key here key here it is key   and this key is a little bit weird it's not in  the center but we can change this pickup collision like this so it is a lot more centered and now compile  it character test map i have my key here and it will still be working exactly  as the parent which is a bonus   because now we just need to change the way  the parent works and everything else changes in the case of the coin because i don't want to  change the c value every time i want to to put   a coin in the map i don't want to do this every  time i'm gonna go inside the coin the static mesh   i'll put it in how much did i hear in the  key did i move this pickup college collection   140 let's just copy it coin also 140  and the collision also 140 compile it   and now every time i drag and drop a  pickup a coin excuse me it will have that height which is better than just putting  them and moving them in the c value   so i'm gonna delete first every other pickup  because these are using the base pickup   and you probably don't want to have the base  pickup the parent pickup anywhere just the child's   and i will move these childs to another folder  outside of the core the core is the base   classes so here in the my 3d platformer  i'm gonna add a new folder called   picaps and whatever i had in my  pickup folder i'm gonna move it the key and the coin to the  other folder called pickups and after moving them here in the base  pickup the parent i'm gonna double click it   and in the event graph i'm  gonna create a custom event and i'm calling it picked this up for now we're not gonna do anything  with it just call it here whenever   i overlap it and i'm gonna do something like this picked pick this up and then gonna  destroy the outer so this will be   called whatever we put here will be  played before we destroy the actor now that we have this setup we can go to the coin  or to the key and add new functionality for this   i don't really need the gold anymore so i'm gonna  close it and the game mode also gonna close it   just avoid having some clutter here and in the  coin i'm gonna go to event graph i'm gonna go   here in my blueprint panel functions and  i'm gonna select pick this up this will   be an override of the functionality that you  can find here and in the coin maybe i want to put a string in the in the  viewport saying you got a car or one coin so now let's press play and if i pick up the  coin i get one coin and if i pick up the key   it doesn't have that functionality i probably  also want to play a sound whenever i pick up   this coin so i'm gonna use play sound 2d  because i always want to hear the sound and there should be a coin  sound somewhere here it is coin let's press play here is the coin and the key  doesn't have any sound now if i wanted to do   the same thing with the key i could just copy and  paste this but probably in every pickup blueprint   i will want to have a sound play so what i can do  is put this node or any type of code that i want   to use in every pickup child and i'll just cut it  and i will paste it in my blueprint pickup here now if i do it like this   if i press play my key will sound but my coin  won't why is this happening because in my coin   i have not tell it to execute the parent code so  i'm going to do that by first making some space   here in the event pick this up right click  it and add call to the parent function this will will make it so whenever and  i can double click this whenever this   is played first we will run this part of the code  and then i will run the string let's press play   it stands here and it also has sounds here now  i want to change that type of sound so here in   the pickup i'm going to make this sound a variable  and a variable is just a little box where we can   store some information we need to define the type  of variable if we just right click it and promote   to the variable this is already defined it's  just a sound base let's compile it and for now   i will clear this value because this  is the base class the parent pickup   and in the coin i will go to the class defaults  and here in sound i will change it to coin save it and compile it and in the key  i also going to go to close defaults   and in sound there should be also a key  type of sound here e let's save and compile   let's press play and now if i pick up the  key it's a different sound than the coin now let's add some specific functionality  for my coin pickup i do want to show   how many coins i have and i will do it in my main  character i won't be able to create a widget i   could do it but it will take me a little bit more  time so what i'm gonna do is here just add a text   render and i'm gonna put it on top of my character  this text render i'm gonna add it to my spring arm and i'm going to reset the positions and i'm gonna put this right  on top of the character i want to see if this will show the text even if i  rotate my camera and it does so it's working good   enough i'm gonna put it like this and i'm gonna  rotate it a little bit first let me change the   or horizontal alignment center text text  button is fine and now i'm gonna rotate it 180 text it may be a little bit  too high something like this and now it is working perfect  i want it to be zero for now and this text will reflect the number of coins  that i have so i need to store somewhere the   number of coins i'm gonna save it in the main  character which means that if my main character   for some reason gets destroyed i will lose  all the coins if i did not want this kind of   functionality i could probably put it in another  class maybe in the player controller but that   is for now out of the scope of this tutorial so  let's create a variable for this number of coins and let's set up its type i don't want to store   half a coin so i don't need a floating point  number i just need and a whole number an integral   and compile it save it number of comments  zero i will have a function here to add a coin and what this will do is it  will set my number of coins to the current number of coins plus one plus zero plus one and you see that i just  drag and drop this variable if you just drag   and drop it normally you get this message if you  drag and drop by holding ctrl you get the get   and if you drag and drop it  with the alt you get a set now with this my number of coins will be  updated but i also need to update this text   so i'm just gonna drag and drop it  i'm gonna set text here it is set text and the text i'm gonna set is this one and i can define the minimum integral digits  maybe i could put two here so i could press play   and for now let me put the text in 0 0 and whenever i add a coin and i can  choose to test it like this at coin in the begin play so after i press play i  will add a coin then it will have zero one   so it's pretty cool let's compile save it and  now we need that whenever we pick up a coin   we want to call this add a coin we will do that  we will do it a simple way if we have some time   i can show you how to do it another  way but for now it is easier if   some blueprint communicates to another one this  is called blueprint communications there are three   types of the most common blueprint communications  this what we will do is a direct communication   and for any type of communication we need  the sender the receiver and the message   so here the coin will send the message message of  uh you need to add one coin and the receiver will   be the main character so in order for the coin  to send the mesh message it needs a reference to   the receiver to get the reference of the receiver  we can go to the blueprint pickup parent and here   in the peaked pickup collision to begin  overlap we has we have this other actor   and this is the other actor that is colliding  with this blueprint over that component is the   component inside this blueprint that has caused  this collision in this case the pickup collision   the other actor is the other actor that calls the  collision in this case the main character other   component is the component inside the other actor  in this case it should be the capsule component   and while the other ones are for more um special  types of collision we can get the results of of the specific the impact location normal  impact normal etc but this is out of the scope so   i need to send this other actor to my picked this  app event so let's click here let's add an input   and this will be of the actor type actor object  reference and i will put it actor that picked this and for now should be fine  i need to connect these two and in my coin i also need to connect these two   and with this actor i can do something like  this i can ask if it's my main character custom main character and if it is then i will just add a coin with this if i press play i add a coin and  it is added and let's add more coins here and see if it is working  and it is so that's awesome   with the coins working we can now pay attention  to the key that right now is not doing anything   what i want to do is have some gates that  will be opened only by some specific keys   and it will depend on the type of key that it is  so we will open this blueprint i will use ctrl e and here i need to save a value of the type  of key it is for example it is a blue key   red key whatever key it is so what i'm gonna  do is add a variable i'm gonna call it keytype and here i'm gonna select as a variable type gameplay tag and this could be a new concept for a lot  of people so what is a tag a tag is some   text that i can set up in my project  settings let's go to a break settings   here gameplay tags and it's a easy way  to compare strings or well categories   whatever you need you can put here so for example  if i want to ask if my player has the blue key   and the red key it will be easier to use gameplay  tags than having to create for example a string   here and then comparing strings so in my case i'm  gonna go here to a project settings gameplay tags   add a new gameplay tags and i  will put here e yes add the tag   here i will have all my tags i can add a sub  tag here key dot blue add the attack and also red for now that way whenever we have to blue the blue  key it will open all the blue gates and if   wherever we have the red key it will open  all the red gates and maybe if we have a   purple gate we need the blue and the red key  something like that maybe now with this setup   i can go to my no not to my coin i can  close my coin for now i can go to my key   compile and save it and in my key type in the  details panel we can change the default type right   now it's a blue type of key so i can put here  blue by default so compile save it and whenever   i want to pick this up let's remember functions  overwrite pick this up if we want to play   this sound we also need to  call to the parent function and now here i should give the key to the  actor that has picked this so i'm gonna main character like we add a coin we can get a key and the input will be a gameplay tag and we want to save it in a collection  of gameplay tags that we can get   so here is this will be the key to obtain and to save it we need to create a variable   like exactly like the coins  but this one is is collected and this can't be just a gameplay tag because   if it was a gameplay tag we can only  have one value either blue or either red so i need to change this to   a gameplay tag container this will be a  collection of any type of gameplay tags okay so compile and save it and here key  is collected let's get the collection we can gameplay tags add gameplay tag and  connect it like this this will make it so   we are getting the key and saving it in  my character again if this character is   destroyed then we lose all the keys so maybe  this isn't the best place to save the keys but   for now we will do it like this now blueprintkey  is actor i need to know if he's the main character and here we will get a key which is the key that we want to give the  character is this one key type this one save it and now let's just go to the main  character to check if this is working   let's print the keys that we have collected it was debug get debug string from  gameplay tag container let's press play   let's go to the key and it says key  blue now if i wanted to add more   keys then we can change these values and  add more keys here in the project settings now we need something to use the key on   and we will create some gates that will depend on  the type of key so let's go to the content drawer   in the core folder let's  create a new folder called gate let's open it let's just put a blueprint  class there an actor is fine blueprint gate   let's open it i need first the static  mesh or the gate there should be   something that i can use here if i  type gate large gate i need just a gate or here gate and add static mesh and it's fine  if it's attached like this this will be force   field because i just saw the force field static  mesh that i wanted to use force field here it is   and now i have this force field and it's a blue  type of force field so if i use the key the blue   key i should be able to disable this so i'm gonna  put this key this key this gate on my on my map   and let's make sure that the gate is pointing the  right way remember x positive is forward so i'll   select the gate static mesh let's call it static  mesh gate and i'm gonna rotate it a little bit so now it is facing forward now yeah perfect i need some  way of interacting with this   because right now it's just blocking my path which  is good so the way i will have to interrupt with   this we already have seen it let's click on  the default scene root add a box collision box collision i'm gonna call it gate interaction zone this will be a trigger it's it will be almost the same as the overlapped  pawn but it will have some presets here   a little bit changed let's not worry about  that trigger will work so gate interaction zone   collision preset trigger let's just make  it a little bit bigger 100 no that's   maybe too much or maybe it's enough this 200  also no that's too little 300 and 200 here and now in the c value when i put  100 that was too little so let's just put it up a little bit perfect  now i have my interaction box and what i'm gonna do with it is again use that  on component begin overlap here i will check if   first whatever i touched is the  main character so the other actor   let's make sure that if it is the main character   and then i want to ask what type of keys does it  have so i'm going to ask here yet it is collected   and i want to compare with the type of gate  that it is this one is by default is a blue gate and i want to see if you have that correct  key so what i'm gonna do is create a variable   that will let me save what type of  gate it is so variable let's put gate type and here gameplay it won't be attack it won't  be a container it will be a query because we   will see in this collection if you have the type  of key that i'm setting up here in this query so   let's compile and save it gate type gonna put  edit and i'm gonna here select any tags match and what tags do i need to  match is the type of key   in this case blue for now  so let's save and close it and now i can compare if this gate type get  game type gameplay tags ah here it is make   gameplay tag query oh excuse me it's not  it was not the make it was the comparing   this one does container match tag query  so this is the query this is the container and if it matches let's put a branch node here if  this is true it means that in the key is collected   i do have the same type that i have in the query  which is blue and i want to create a custom event   just for clarity's sake and for cleaning the  code here this custom event will be open the gate and if this is true i will open the gate  for now opening the gate will mean that the   force field i will disable the collision so set  collision enabled to no collision and i will also   hide it set actor no set hidden in game  i'll set it to true so with this intro   i will press play here i cannot pass  if i get the blue key now i can pass if we see this again it is looking a little  bit too rough around the edges because it   just disappears and what i can do especially with  this force field i already checked the material   here i can double click here in materials  and it will open this type of material   and it already has a value called  opacity and if i check click the check   and then move it around i can change the opacity  of this element which is really really cool   so this is something that we can modify  in blueprints so for now i won't save this   but in order to modify a material parameter  which is that opacity that's a parameter i need   to first make it a dynamic material so i'm gonna  do exactly just that begin play i'm gonna create dynamic material instance and this one already  has the static mesh force field selected it   will reflect this name so i'm just gonna use use  it i need to make sure here i missed my static   mesh that the material in this index is 0 here  element index 0 also and the source material   will be this one so i'm gonna find it like this  and i'm going to assign it here with this arrow and the only thing i need to do now is save it as  a variable and i'm going to call it force field dynamic material and well reference because we are referring to this  created dynamic material instance   now when we open the gate we can set up instead  of hidden in game we can get this dynamic material   set a parameter in this case is  a scalar parameter value because   it is just one number it's  not a vector it's a scalar i will put it to zero and this is opacity and  i'm not sure if it is in all caps or not so let's   check it again material here this is the name  we can right click it and copy display name   and then indicate paste it here let's  press play let's see if it works and i need to have the key it is working but  now with this parameter i can create a little   animation with my timeline i'm gonna type  timeline at timeline this timeline will be   course field opacity or it could  be timeline opening the gate now what is a timeline is a special node that  can play a curve so how do we modify the curves   let's just double click it the length i want  it to be one the track i need a float track   we can have vectors events or colors i just  need a flow track this will be the opacity and here i can define the curve we can right  click and add the key or we can shift click   and we can also add any key the opacity  will start in the time 0 with a value of 1 and it will end in time 1 with a  value of 0. we can use these arrows   to frame those keys but this is  the curve that will be played   whenever we use this node so we can close it and  here we will find that my timeline has a new pin   called opacity whenever we open the gate  we want to play that timeline and every   time the timeline updates i want to update the  opacity value like this so let's play press play   let's get the blue key and now we can see the  force field disappear which is pretty pretty nice now that we have the pickups the keys and  the gates working it should be a good idea to   know how to create more keys more pickups  or well another different type of gate   so for example we will do this approach  let's say we don't want to create more keys   we could just like we did with the pickup   where where is our key folder or pickups folder  here we can just create a child grouping class   and change the values or if we open the key we  can hear key type open the eye of this this means   instance editable which means that any instance  of this actor of this blueprint that i have   in the map for example this is an instance if i  duplicate it i have another instance i can make it   change so here edit red let's just save it  and now if i press play i get the red key   i cannot open this blue gate but if i had a blue  gate a red gate excuse me i'm gonna duplicate this i cannot change the value because i  have not make it instance editable   so i'm gonna go to the gate here  in the query i'm gonna open its i   this may makes it an instance editable  gonna compile it save it and now in the map   i can edit this and here no i don't  want the key blue i want the key red and i will save it now i can press play   i get the red key i can't open the  blue one but i can open the red one if i needed both edit edit and blue and red let's  see if this is supporting both let's press play if   i get a red it is still working because it now  it will open with any of this one the red key   or the blue or the blue key the blue or  the red but we can here instead of any   tags match all tags match and now i can  add the blue on the red save and close   press play if i pick up the red key  won't work but if i pick up also the blue   key here i know red and blue that one opened  with the blue and this one open only with both   now we have changed the values here but we  have not changed how it will look so here this   is remember the red key with any blueprint i have  access to its components here in the details panel   these are the components of this blueprint and  i can go to the static mesh and change this   material so instead of power up a there is already  a red material so let's put power up a3 and that   is a red key i did not have to create another  blueprint that will only change the way it looks   for the force field in this case let me make it so  i only need the red key like this save and close i can also check the force field this is the  material instance and i can change the color   so for this one and where is it here  it is i will browse to it i will   duplicate it call it force field red gonna  open it and change its color multiplier so this one could be this red like this okay and now i will  use this red value here in my map   force field there should be a force field red here  it is and now it is it will work as as expected   but it seems that it didn't save it  for some reason let's just save this   if this doesn't work then something  in that material must be changing   my my color multiplier not to worry we can  also go to the gate create a here also in the   when we create the dynamic material instance we  can use set material instance to change this color   multiplier let's copy the display name  let's put here parameter a set parameter   and in this case the parameter is a vector  because it is a color so set vector parameter now i will put the name   color multiplier and this value i will make  it a variable this variable will be gate color gate force field chord let's be a little more  specific it's it's good for your variables to   have a very easy name to understand understand  if we just created variables that ah this is   s and this is x and this represent the velocity  and the location it just doesn't make any sense   later on when you check the code again  so here this color i'm gonna set it up   the same as this blue so i'm gonna copy the  value and here i'm gonna first compile and save   paste the value perfect compile it and make  it instance editable this way i can return the   this gate material didn't work that  approach so let's just reset it to default   but we can here instead of selecting the  components we can go to the blueprint itself   and in gate force field color i'm  gonna change it to the red one if it's not changing is because this code is  in the begin play so we won't be able to see   the change until we press play  but now we do see that change   so maybe you can do a combination  of both if you want to also   see it and i'm gonna copy this red copy and  i'm gonna paste it the blueprint paste it here it's almost the same so we  press play we get the blue one   this open this doesn't open we get the  red key and this open and the other does before building the gameplay map i wanted to  polish a little bit the celebration part because   right now if i reach the gate like this is it  just says you won and it doesn't look really   nice so what i'm gonna do is first the  main character needs to save a state   a celebration state so let's create a  variable let's call it is celebrating and i could do it like this but let's  just say that they're me more they   my english is failing they may be more states  that you could have or that you would want to   have so a better way to implement this will  be here creating a numerator inside the layer and here i'm gonna go to the category blueprints  enumeration i'm gonna call it e character states   and here it will be the first value none second  value default and the third value celebration creating a celebration here and yeah celebration  blueprint main character is celebrating let's just   not call it that let's call it character state  and here let's call it the type should be e characteristics this one by default it should be default   perfect and now we should have a way of  entering that celebration state so let's go to functions enter deliberation and this  will change the state to the celebration and also it will spawn and ayagara system system at location the location i know i have this celebrate so let's  test it like this get actor location and also get actor rotation like this and let's just test it how should i enter this  in this celebration well you should only enter   this state if you win how do we know if we  if we won in that game state so let's open   game state 3d platformer you want we can leave  the message but now i can get the player character cast it to my player main character and here it  will enter the celebration let's press play let's just let's just speed run  this we don't need to walk all the way here we can   just right click here play from here we will enter  it and we have that celebration and that should be   follow me around so let's go here instead of a  spawn system at location spawn system attached the template should be celebrate the attach  component should be this capsule component and the location tab type should snap  to target and keep the world scale let's   press play and let's speed run  it like this play from here   and now it is celebrating i need an animation  let's go to my well let's save the game mode   this is already done let's go to the animation  blueprint let's select the skeletal mesh component   double click well here a nim  class search it double click it   and now here in my locomotion i can  have a state of celebration celebrate and i will only enter if the character state here is and this should also be character state and i don't know how to type here it is if this is equal to celebration it will be true and it  should enter this animation let's copy that   and if i need to leave this this  state otherwise i will get stuck here i can do the opposite if it is not celebrating so is that not boolean not the other  one the other one is a comparison   so if it is not celebrating then  we return to the normal behavior   we press play and let's not  forget to do this play from here now it is well it is not happening  nothing is happening because   i didn't add first i didn't  add the animation celebrate should be any of these ones i believe let's just put this one and also i have not set up this value so i need to  go to the event graph i need to get the character   and here i need to do another cast and i  can copy and paste this tri-get pound owner   as to main character and ask the character state and set my  character state with that character state like this and let's not forget again play  from here and now it is celebrating   it is looping and i can move around this  shouldn't be possible so we can add a little check   here in the event graph let's just close the other  functions and in the movement input i can ask if it is celebrating but what i'm gonna  do is create a function called can move and here this function will return  a value a boolean value return value this will be a pure function and we will  see what's the difference in a minute and i will only be able to move if my  character state is equal to the default one this allows me to add more checks if i need later   so can move i'm gonna use it here now  the difference with a pure function and   a normal function is that the normal function will  look like this and can modify the values inside   the pure one looks like this and will only  return some value after calculating something   usually a pure function won't edit  any value of the variables inside it   you can make it do it but usually it's not the  way so i will copy and paste this can't move and now if whoops   if we play from here we go here and now i  can't move even though i'm pressing w s d great one thing that i noticed while i was testing  this is that what happens when you fall from here   you would need to respond somewhere right well  we can create this little response system easily   first we need to have a way of knowing where  should we respond so let's go to the gameplay   well to the game mode excuse me game mode and  let's save a variable called respawn point and i'm gonna put it as a transforms because  a transform will have the location rotation   and scale now we need to set up the first  respawn point point and that will be the player   start this one so here in my game mode and at  the beginning play i'm gonna search for the   for the player start get actor  of class there should be only one   unless it's a multiplayer game where there are  multiple player player starts but usually in   a single player game it's only one so here get  actor from class player start gonna get the actor   transform and i'm gonna set my respawn point now we have this respawn point we need to  know when the character falls so let's create   a blueprint that will help with this here  in the core there should be a folder called respawn system and here will be blueprint class  an actor this will be a height kill volume and there is already a volume  like that it's called qc volume that we can put here and  then if this is big enough it will destroy our actor but we really don't want  to destroy the actor we just want to respawn it so   check you can check how it works it just destroyed  the character we don't want that we don't want to   complicate ourselves too much with it we just want  to respawn the character or just teleport it here   so that's why we're creating our  own blueprint height kill volume   let's just call it height respawn and let's open it we only need a box collision and here we just need to overlap only the pawns  excuse me overlap only pawn and begin overlap   when we touch this box what we are gonna do  is just teleported the character the actor we can check if it's a main character or not  for now i'm just not gonna bother with it   we can just teleport it where do we want to  teleport it to where the game mode tells me so here we will cast it and now we can get the respawn point  get respawn point we can split it   and we have the location and the rotation  that we need let's compile save it play it   and we haven't added this to our map so it won't  work height respawn volume gonna put this one   here and if you want a better way to  increase these values we can go to the top   and now we can make it a lot bigger by  scaling it or by changing its values for now and by changing the values i mean here going to  the components in this box component we can add   this box then maybe to 100 but i will leave it  like this i i just want to scale it up or down something like this to cover everything remember  that our character can be here and jump that way now let's go back to our perspective let's  press play and whenever we touch that we respond   wherever our respawn point was now we can have  multiple respawn points that we can add and we   would just need to change this value this is what  we usually call a checkpoint so let's create one   we don't really need this height respawn  volume anymore we don't really need   this animation blueprint also  the main character probably we do so let's create that checkpoint here  response system checkpoint is also   a part of the respawn system so let's add the  blueprint class here actor blueprint checkpoint and we need a static mesh as always and we need to find i don't know  if there was a checkpoint here no   let me remember which assets do i have at hand this could be it button ring and the button and if i press the button there is a  checkpoint yeah that's seems cool enough   we have the ring here we can select the button  and this makes it a lot easier and here we   select check the press on the add button and here  you can check that static mesh has in parenthesis   the static mesh that we have  selected in the content drawer   so we have the button there pretty  good pretty good so now we can   do something with it for example in the  defaults in root let's add a box collision and with this box collision let's  just modify some of its values 100 and here maybe 50 and 50. could also be a capsule doesn't matter   but with this this will also be a trigger let's  go to collisions trigger and begin overlap   whenever my character overlap this i want  to update the respawn point in my gamemode we could just get gamemode cast it to my game  mode my 3d platformer and from here we can set the respawn point but it is a lot cleaner to have a function  here in case we need to do something else   after reassigning the respawn the respawn  point so i'm gonna call it update respawn point and here we just set it like this  and as an input i need a transform   now in the checkpoint we can just  call update the respawn point   we need a respawn point that transformation and  because i don't want to make some calculations   to know what is this point because this static  mesh has a zero zero but it won't i can't spawn   my character in the zero zero because otherwise  my character will be like this stuck in the floor so to in order to avoid that  we can have a little arrow component and this arrow component will be on the  root do not make it the new root just attach it   and reset anything that it has here and it  will be like this something like this maybe   that should be working compile it save it  and in the event graph i will need the arrow let's get the world transform otherwise this component will  give me the relative transform   and the relative transform right now is 0 0 110  but the word transform will depend on where do i   put that checkpoint so let's use that checkpoint  checkpoint i can find it find it excuse me   browse to it here it is let's save and  compile it and now we can go to our   character test map and if i fall through here i  respond there if i go here and then respond here   i'll respond in my butt i should be able to make  this button color change so what we can do will   be to change the matter the material here there  should be a lot of bottom materials bottom one   here we have blue and green so here maybe after i  update my respawn point i can button set material and i can assign it the red one and  oh let's use the green one press play and now we can know that that respawn is activate now you will find it that  let's say we duplicate this i activate this checkpoint i fall  down it works i activate this one   i fall down it works but the  other one stays active we can we can fix that if in my game mode in the update  respawn point i also am sending the checkpoint reference and this will be a checkpoint and in this checkpoint reference  i will save it promote to variable   call it it was checkpoint reference is fine but  i'm gonna call it current checkpoint reference i'm gonna set it like this but  before setting the reference   i want to make it go back to  the way it was before so here i need to tell it to go back  to the way it was before   in the checkpoint i will create a custom event return to normal and what this  will do is just set the material   to the other one which was button a like this and here in checkpoint ref i  should send this blueprint or self   can do it okay let's call it self here self  get the reference to self and connect it to   the checkpoint reference if it doesn't let let me  is because i have yet to compile it now it should   let me self-object reference is not compatible  with checkpoint of object reference why not dude   let's just refresh this node  refresh it still not compatible what let's just create this update respond respond point and what is  this and itself is not it but this is a checkpoint oh maybe maybe maybe  it was because this value we had two checkpoints yeah for some reason there was two checkpoints  i'm gonna select the second one and i'm gonna   compile it's gonna throw me an error here and i'm  just gonna ignore it for now is if this is what   now it's correct yeah for some reason i  don't know why it created two checkpoints so it could happen now i'm sending the  checkpoint reference i have a way to   return to normal so in my game mode here this  checkboard reference let me delete the last one   i'm gonna promote it to a variable call it current checkpoint reference and before before i set all of this up i'm gonna  use a sequence here sequence is a node that can   let you organize your stuff   pretty easily and if you don't like cables you  can also get checkpoint ref this is the same as getting it through here get respawn point  this is a good knowledge to have and i'm gonna   call this new respawn point so it's easier to to  know which which one i'm getting get new respawn   point now i know the difference between these  two perfect and before i do this i'm gonna check   if my current checkpoint is valid and if it is valid you can do it like this  or you can do it with the macro like this   but if it is valid i'm gonna return it to normal and with this code we can save compile  it press play seems i have an error here   what's the error a spawn location  it change compile it let's checkpoint i have to check points what oh there exists another checkpoint the  one that comes with the hour of code   we could just ignore it just just ignore it  ignore the the error message i should even   delete it yeah i'll delete it so you  see it's it really it's not important and it's been referenced by this the  reference for the date okay let's press play   let's go to my first checkpoint it works last  checkpoint the other one returns to normal   and it is still working now that we have all the built-in blocks  let's create a map that can use them so i will   create a new map new level empty opt-on  world create and well i'll save it save current level and this will be the level one i will use the modeling tools to  create a prototype very very fast and   where is x positive here it is let's say  we start right here on a big platform and this is just pulling and pushing push pull i'm just using q and e to make it  faster and then it will be a quick jump here yeah like this i don't want it to be  too hard so let's put the corner mode   select these two corners and q  and e to make them a little bit take them a little bit down  now press done let's continue something like this maybe now you need to jump here now i don't really  know if you can make those jumps so it's   a good thing to test it so put complete we need um where is my player start put it here we can play now  but it will be everything in black so   let's add those lights so what  we need is a directional light to get better shadows the skylight what did we add also visual effects sky  atmosphere what else our clouds there they go and the exponential hyphen a lot  better now let's try it let's test it   this should be an easy jump very easy jump  this one also i missed that but is it possible   to make it from there should be but i  want to make it through an easy jump   ah just a tap jump and doesn't seem to be  possible so let's change it a little bit because these are the first  jumps come on should be easy slide forward corner mode and let's see  if that that makes it a lot more easier a lot more easier perfect now what we need to  do is introduce the first double jump double   jump and hold jump i mean we need to make it  so the player learns that you can hold the jump and that it that will be  something that will be needed so first this should be an easier kind of jump  that you just press once and you just get on topic   of on top of it let's go back to the cube grid  grid in our modeling mode and then let me just select this part 2 3 and now you shouldn't get any type of option  otherwise our player will feel lost so   the player will try to jump and sooner or later  it will have to hold the space bar it will   start making sense like it doesn't this should be supposed to to be easy easily jump over  but the player won't be able to do it until it   learns well until they they learn to hold the jump  and there are not a lot of other places to go so   it's like a mandatory learning without telling  them that they will learn this i'm not really a   big fan of games where you need to put a lot  of cues or signs telling them what to do but   for me this should be fine i  need some kind of platform here and here this zone will be like the end game why because i will  put the gate where's my gate here's my gate here   and i will require the player to have let's  set it this gate type gate type to alt tags   match and we need the blue and the red save and  close and for the color i will choose a purple   what kind of purple it will be not  really sure well i can tweak it later   but whenever i press play this should  be purple it's not a red it's not a blue   purple fuchsia i re i'm not really good with  colors but here you should be able to see the   the goal so then we can have  some backtracking to get to it so here i will put another kind of room and the goal just like that now we need  to do some more platforming   so we should be able to pick up any key and start going through platforms and gates and pick  up some coins so the game feels a lot more fun and i mean this is a really straightforward  map so what i will do is just prototype a little   bit and i will speed it up because i already  told you what would my thought process will be i will speed up this part so you don't get bored  with me playing around with some level design   here i'm just trying to block out the  level trying to get the distances right   trying to make it a little bit  interesting i will make two branching path   one to get the blue key the other to get the red  key i believe that i put the gate in purple so i   need both of them but that would mean i would need  a red gate somewhere so it makes sense like oh you   get the red key and the blood key and it gets  combined so i didn't want to add another path   to to the level so i just put the the gate back  to red so first i need to go through the left side   to get the blue key and then in the right side  i get the red key that will lead me to the go and as you have seen i'm mostly  testing the scale the distances   trying to make some interesting shapes   and it's good to know that everything that i do  here later on i don't really need to follow it like very strictly is just to get an idea  of how the map will look how the map will be managing its distances and well  here i'm playing around with the corner   corner tool to make some ramps and i will notice  that if i try to go up that ramp the angle is too   steep so i need to later change that and again  even if it later doesn't fit it doesn't matter   because whenever i start decorating the map with  props then it will be easier for me to know the   true scale but at least with this part of  the process i know how large the map will be   i can get a sense of the mechanics that i'm trying  to teach or that i'm trying to use in this case   this last part is all about jumps that  are long or that you can easily miss   and the other part the first one was precision  jumps that you really don't need to hold your   space key but you need to be a little more careful  with how you're jumping if you jump too much   you fall down if you am too little you also fall  down and here well i change the key to a red key   and the gate pulse so it is it is  easier for me to finish this level   i finished the blockout but one thing that i  should really mention is that whenever you open   the level i close the project recently let's just  open the level one you need to have this window   and word partition word partition editor otherwise  you will see everything blank and then here   you will select these cells and right  click it and load the selected cells this way you will have for your  map and well if you create a   much bigger map then you can choose  to just load some part of our map   so here i already tested it it's working pretty  fine and i just wanted to add some gameplay   elements for example that part is is easy enough  but still if i die here and i have not put my   my height with spawner so it would  be a really good idea to do it   where's score respawn system height and i'm gonna  put this here gonna go to the top perspective and just make it fit with the level and be sure to overextend this just in  case something sends our character flying   and you really need to have this collision and it would be a good idea to increase the c  value a little a little bit just in case the   velocity is too high and you end up skipping that  the trigger shouldn't happen but you really don't   know whenever someone else is is playing your  game so here now i can press play if i fall down   i'll start here usually this part should be  an introductory part where uh you can fall   and here you should enter some some place  so if you die here for example in this jump   i really don't want it to go back to the  start so i will put a little checkpoint here and it should be really really  visible so the player doesn't skip it so you will see this immediately  oh what's this seems to be light up   and whenever the character falls then  you should be able to respond here now these parts also should be very  easy except this one could be a little   rage inducing yeah it's it's really tricky  actually so i'm gonna also put a checkpoint here here you if you fall through this gap  it's fine you you can go here and maybe   because this will be a second part where i   only can access after i get this blue key  and i go back through this path and then and then go through the gate and  here probably we already took this this checkpoint and it's really not that  difficult and it should add a little bit   of tension if you fall here and go back here  then it's like oh i really need to get my jumps   on point so i believe it is fine like  this the pickups well the coins i will add after the set dressing of this map i will add  some props and make it look a little bit better   for but because right now everything is gray  so let's start with that this part will also   be sped up because what i'm gonna do now is  just replace most of the geometry if not all   by the assets that we're gonna use that  we have imported from the other project here you see me scaling stuff up and down it will  be probably better if i get rid of the snapping   in the rotation and in the scale so  i get a more natural scale scale so that's pretty much what i'm doing right now and regarding the scale usually it won't pixelate  too much or it won't be that noticeable if you use   a 1.75 scale so maybe with 2x scale it can be  noticeable but it really depends on the assets   depends on how realistic it look  looks the texture in this case it's   a very cartoony type of feel so  it's a little bit harder to notice   also here i'm adding some rotation so  those surfaces are not looking too plain   because a simple surface that constantly repeats  itself and it's in the it's parallel to the   to the ground sooner or later it will get  boring and i'm not gonna worry that much   right now by leaving those blank space because  later on i will probably do another pass   with more props to hide anything that  will look kind of weird or not believable also in some part of this video i  will select the geometry here in   that that we created with the modeling tools and  remove the collisions and also make it hidden   put it in a folder so i can hide it and find it  really easily and also set the value of set actor   here in game to true that way i can press play and  i won't be able to see it and i won't need to just   delete that geometry because maybe later i could  i can review what what i need from that geometry and in this part it happens i'm showing  something that happens very frequent   you're putting the props and they don't exactly  align with the with the scale that you have   proposed for your game or with the height  in in my case those stairs were too high   and it made me have to elevate  everything by a little bit here i'm just   testing that the jumps are still doable  and after that after positioning in the   quote-unquote correct place i can now move it  around and position it to the new height that way   i know that those jams are still doable and i'm  still keeping the distance that i planned before so yeah here i also need to add some collisions  to some props and this will be very noticeable   when you start play testing you will see that  i'm putting assets in this case this stair   had an angle that it was too steep so i  just went inside the character to fix that   you can find that value in the character  movement component and it should be should be something like angle to walk on and i  just bump it up to 70 i believe so play testing   like i was saying very important will let me see  this kind of errors before i just think i'm done   with the with the map because if you don't catch  these errors then you will show it to someone else   they will get stuck and you will feel defeated  i mean it's still a learning experience to have   someone play test your level but you want to catch  most of the errors with yourself play testing it so that's why it's important and you don't  really need to play test from the start   here in well in most of the times i'm play  testing i'm just right clicking in the map   and clicking in play from here so i don't need  to go to the start of the level and to reach that   part that the specific part that i'm testing right  now i determined that it was too easy maybe and i   started moving around the the platforms and here  these jumps they were especially somewhat annoying   not too not that much so it was something that  i wanted to maintain so i'm using those cubes to   try to get the same scale the same  distance that this part offered   you will see that right now i'm following the  geometry exactly oh well almost exactly as it is   but i will take some liberties some freedoms  in the positions and rotations later on   or i do believe that is at the end of this sped  up video that i'll start rotating some stuff   but this first pass of assets let me know that  this is still working as well as my prototype   as my blockout and here i'm rotating it and even  though though i have been changing it by other   assets at least the floors the platforms  are still working after having the floors   changed by the meshes that that we're gonna  use then we can do a second pass of props   where we can add all the stuff that will make  it look a lot better in this case some foliage   won't do us any harm and we can tweak a little bit if it is not working for example  if the plant is under empty space   then we can move it or we can delete it  then we are using some props also from the from the marketplace from that free asset   to make a little a little foundation for  our i don't know how to call it maybe house   or whatever it is where the goal is right and  we're just trying to make everything first look   similar and then start adding some details  for example that wall with with the window and using the same assets that that i use for  the platforms we can just rotate them scale them   and position them in a way so they look like  rocks so it's really not necessary to create   that much assets with and i would have prefer if  it was a complete rock so that would have made   my job a lot easier but just by rotating it and  putting it together with other other platforms   i can make it seem like it's a bigger construction  that what really is so by using the parts   now i'm trying to make the go location a little  bit more noticeable i mean if something has a gold   a gold border then should be really important  right and i'm adding a roof just in case you   can jump from another platform to that to that  area so that way i'm making sure that this area   can be only accessible if i get the red key  also i'm playing a little bit with the lightning   and that lighting inside that room should  reflect that it should is an important route   or something like that also i'm adding some  some meshes in the bottom of floating platforms   just to make it look a little bit more  believable that is not just a floating   floating floor the next part is  trying to make sense of the other gate   and later on i will run into a problem where  i can cheat and skip that gate but it all   comes down to play testing you will still see  even though this this video is sped up like   800 percent so hopefully it is noticeable but it  is it took me a long time i mean i'm not really an   environment artist or a level designer  i i know some principles of level design   what to take in consideration but because  it's not something that i do often   it is taking me a little bit of time took me like  an hour and two minutes but it was really fun   so i really didn't notice that i'm passing here  i'm trying to create some crystal structures   using only one prop and rotating them  grouping them and then duplicating them   and later on i will try to add more more of that  those crystals designs to more parts of the map here again i'm trying to get rid of just floating  platforms voting boxes that's okay i believe   but just uh almost a plane she didn't really  look that good to me here i'm trying to avoid   the player skipping the gate because you  could you could jump through that hole and   you really didn't need the blue  key also you could jump to the side   and that was also an issue so i try to to  fix it by just blocking that that part and   some some parts that just really  a little bit of touching and care so here we have beam up it's looking a lot better i mean i did my my best so yeah it was pretty fun took a long time but at  least we have the map there are a little details   right that we can add oh or well that i should  add for example here i know this diet i had some   where is my static mesh some clouds and  these clouds are very big so i can put them   in the base something like this and also the cloud b should help me a lot and this cloud if i scale it maybe by 10 will allow me to kind of give the idea that i'm really up   up there in the sky so this  one i'll scale it by eight and again put it someplace like this and i'm  gonna get rid of my snapping tool i'm going to move them around a little bit something like that maybe a little bit lower or to the side and i can even rotate rotate it to make  it look like it's completely another asset this one is looking very similar so i'm  gonna rotate it also maybe to the side and then would put it someplace like this move this one around and let's press play and see how it's looking um it's a little bit better i should also use these  clouds and put it in the sky like so maybe one of these ones here also where's the other the cloud d and this one shouldn't cast shadows  otherwise it will look a little bit weird   so i'm gonna select them go to lighting  cast shadow don't let them cast shadows and again i'm just winging  it i don't really usually do   environment art or nothing of the sort but  you see that the tools give me a lot of a lot of room to a room to play with it  then yeah and the harder i try to talk   while doing something the harder it gets  let's press play we have some clouds there i mean it's supposed to to  be a little bit cartoonish but this is maybe too close and i also had some effects there  was a wind system which is a   a blueprint that i can modify the curve for  example like this and create another node and it will give like a wind  moving around there it is and this type of blueprints are very  useful because it can help guide oops the the way and this is not what i wanted to  do so i'll again search for the wind system here for example let's put these like that and i'm gonna move it a little bit and then see what's happening with that so it  takes a little bit to appear but there it is and i really should extend that  cloud that's that sea of clouds   oh and i get some nice reflections out of this pretty cool also another thing  that can help us a lot for example let's just select all these clouds and maybe group them with ctrl  g duplicate them rotate them make sure that you don't see that they're  actually the same assets something like this something like that and let me press play and see see how it's looking play now it does see it does look  like a like a sea of clouds and i have clouds there and there and there and the last thing we need to do is test  the is the level see if everything is doable   everything is possible i hate this part i really hate that part yeah i can do it i can do it it's so tricky that jump you don't  even know dude i can't be that bad usually with those type of jumps better to do it from the side yeah like that finally got the blue key this is a simple  cheat i just die and i returned there on this checkpoint let's see if this working  probably that needs a sound i forgot completely   about that so i mean it's good because  the punish the punishment is not that bad we got the red key we probably can skip most  of the way back going here then here it is be a lot better if if my character faced   to the other side but that could be something  that you guys can add in your project so everything's working correctly something that i forgot to add before wrapping  up the video was some particle effects   here there should be something called  pollen and i'm gonna drag and drop it here   and it gives me these types of  particle effects of things flying   to make everything a little bit more magical and  i'm gonna drag and drop one duplicate it here just so i have this kind of  effect everywhere in my map yeah that's looking a lot better and now that the map is finished also   it's good to label everything we've  done for example everything with bp and an underscore should be except these ones  gameplay elements we can create a folder call it how do i rename it there it is gameplay then with this in mind i can go through for  example these wind systems should be vfx the pollen also no how is it cold than this these two assets new folder no not new folder excuse me let me delete the new folder or did i delete everything here win system bfx what's this name bfx pulling magic  camera let's search for that bfx what why can i find them should be around here well for some reason is not showing up while the lights i can add to a folder called lighting and most of the the meshes will be the level  you can leave it like this or you can also   send everything there and separate it maybe with  level environment obstacles etc but it's a good   a good habit to organize your outliner this  player start should also be in gameplay some lights here skylight let's move in to light  but it's a good idea because if you go back to   this level in maybe some weeks or after months  it is a good idea to to have it categorized and   in a easy way to find any asset that you may  need so when i press play i should have those those little dots and i don't know what happened  to the other one so i'm gonna duplicate this one probably it got deleted without me knowing but now i see it be sure to save and after saving be sure to check  it out now it's looking a lot better   got my clouds that one looks a little a little  bit weird but i'm not gonna get too picky about it one thing i did forget to add was my  coins usually the coins will guide   the player so let's just add them really  really quickly where's my pickups coins should the first one should be here the  second should be here if you don't want   the player to skip this part you can just  duplicate them here i'm gonna put another one   in the top so they know they should be able  to reach them i'm gonna put three coins here i'm gonna put a coin here so this will probably be a point where  they are very likely to fall down i could put like some x here coins and last but not least some coins leading to that here i'm  gonna put a coin in each one of these   platforms so if they want all the coins  they will need to jump on each of these   platforms and this one really doesn't  need a coin because we have a key here again a coin here maybe a bunch of coins here and now whenever we play we will have these coins they are a little bit static i don't  like that makes make it seem so   i don't know boring so i'm gonna make  them rotate i'm gonna open the coin   gonna go to the base pickup and  here i'm gonna add rotating movement compile this will make all my pickups   rotate even the keys the key i really don't  want it to rotate so rotating movement i'm gonna   uncheck this how to activate compile it and  in the coin i'm gonna check the auto activate   so only the coins and i'm gonna simulate  only the coins will be moving like that   and the keys will stay static if you want  to create a hovering movement you can also   we can also do that through components  here there should be an inter to movement   again i don't want this movement to auto  activate first but let's check how it is moving   i don't want it to be a one shot ping  pong should be fine teleport type is fine   sweep check if still in world i need to define  this control point so i'm just gonna put the   first one at zero zero and the second one  maybe minus 40 the duration will be 0.7 compile save it and we will see now what  happens with this and it's really not a smooth   a smooth movement but for me it works you want a  smoother movement then you can this control point   made it to instead add another one   minus minus 30 and here our end goal was minus  40. that should smooth things up a little bit just a little also this one i should disable that how to  activate and it was still a bit stiff so let   me put -5 3 5 here it save it compile it and  the coin i don't want it to move i only want   that key to move up and down so here in the  key i will activate that interp to movement compile it save it and now i can see  the key moving around as expected so if i do play the game i will see  something moving there up and down   which should really call my attention i see  the gate the red gate a key and now i can start   getting those coins and the rotation is too much  for me let's change the rotating movement to maybe a third of it let's see if that's working  for us yeah and that's pretty good let's   keep it like that to recap this tutorial  we have seen blueprint fundamentals   also gameplay development and a little bit of  level design we have created a game from scratch   we have also added gameplay mechanics using  blueprints and created a level that can be   played and shared with your friends the next steps  for this is that you can use this knowledge to be   able to design more levels and create your  own gameplay mechanics so the game becomes   more unique and also it will open the door to the  exploration of all the features inside the engine   if you reach the end of this tutorial be sure  to check the comments to find a coupon code for   one of our premium courses only available for  the first 100 people
