UE5 C++ 53 - How To Async Latent Action Blueprint Node With C++? - Unreal Tutorial CPP Function BP

how to create async action blueprint nodes with C++ in unreal because even though a delay is pretty fun a delay that does something is even better um actually I feel like I already said that before uh oh yeah there are two main ways to create a latent blueprint node there is the latent action that we saw in the previous video and also the blueprint async action that we're going to see today so we're going to compare them both and see which one works best so let's get to it and here we are in our header file but before we jump in the code we're going to take a quick look at all the upsides and downsides I found when comparing the latent action with the blueprint asnc action that we're going to do today so these are my upsides and downsides obviously depending on your situation maybe some upsides might be considered downsides and vice versa depends what you need but in my case my upsides are that first we have a direct output execution pin in our blueprint node which means that if the latent action fails to be created it's still going to trigger an execution pin after calling the blueprint node which was not a thing for the pending latent action if we failed to create a latent action in the previous video the function call will just stop the blueprint execution flow right away you will not be able to run any other blueprint node after this call so that's a big upside in my opinion then you have a actal object that you can use in Blueprint after calling this blueprint node so when creating a new blueprint async action it's going to create a new object for you and then you have that object that you can reuse anywhere else in the blueprint to access the variables to call some function to do anything else with it so that could be pretty useful depending on the situation and finally it's also possible to trigger the extion pin at any point in the code you don't have to wait the end of the update like in the pending L detection you can simply call the exection pin and it's going to be called as soon as you need it and that's really awesome actually cuz you can really have control over the execution flow of your code and that's pretty awesome and then you have some downsides though every time this function is called it's going to create a new object that object right here it's an upside that you have an object but every time you call the function it's going to create a new object a new instance so you really have to keep track of which instance you're using right now otherwise you're going to end up with a bunch of weird random bugs here and there so yeah you have to keep track of that and actually related to that you cannot easily get the running instance if there's one so when you call the blueprint node it's just going to create a new instance for you but you don't have a way to retrieve the currently running instance not without creating any custom Logic on your side which is totally possible but that's not something we're going to do today so today we're going to have to deal with the fact that we're just creating an object the object is running you cannot really access it easily and that's it we just have to deal with it and actually related to that you cannot really add extra input pins to your function to affect the current action for example you cannot cancel your action by calling the same blueprint node you cannot have like multiple execution pin one to start one to cancel one to update or modify the current action you cannot do that you can only have one input execution pin and that's just going to start the action once the action is started you can still cancel it if you want to but you have to go through the blueprint object that was created so it's going to create an object and then you can use that object to call the cancel function you cannot just call the blueprint node one more time to cancel the action because you don't have access to that running object actually so you don't know which object you want to cancel and finally the last note is that you don't have any control to when the object is going to be destroyed you can flag Onre that the object is ready to be destroyed so your timer is done your task is done your action is done you just want to destroy the object you don't need it anymore so unreal please destroy that object unreal is going to destroy it one day in the future yeah so that can either be really annoying depending on the situation or you just don't care about it that's just something you have to deal with if you want to use this system you just have to keep in mind that your objects are still alive until they are destroyed which can happen anytime in the future okay so these were the upsides and downsides and finally I have some additional notes the code today is going to be way simpler than the previous video it's just how the system is it's super simple compared to the previous one and finally there's one little requirement when creating your code the class that you're going to create so the blueprint Asing action that you're going to create right here must have at least one static function returning the pointer of the class so that's going to be the blueprint node we're going to create so when using that class unre is going to try to find a function that returns a pointer to that class or a pointer of your class right here and that cannot be done outside the the class that has to be inside the class which means that you cannot just place your function in a function library for example you have to place it inside the async action you're going to create there's nowhere around it that's just how it works it doesn't really matter actually it works the same way as if the function was in the function library but is just a weird little requirement but anyway okay that's it for the notes and now we can finally jump in the code and the first thing that we're going to need is to little include right here at the top we need the delegate combinations because that's how we're going to create the exection pins on our blueprint node so we need that include to be able to do that and then we also need the blueprint async action base obviously because we want to create a child of that class those two includes are inside the core and engine module so we're just going to make sure that both of those are already inside the Builder CS file or add them if they are not I have my core module right here and I have my engine module right there perfect I'm ready to go if you don't have them make sure to add them obviously but anyway I'm just going to go back in my header file and now we can start looking at the logic so I'm going to scroll down all the way on my notes right here and as you can see I already created my class so my class is going to be U async count seconds and it's going to be a child of you blueprint async action base that's the parent class of all the async actions in the engine so that's the parent and then you can just create your own class under it in my case I named it count seconds because that's what we're going to do we're going to do the exact same thing that we did in the previous video so we're just going to create a simple blueprint function that counts the seconds and update the user every every x amount of seconds so super simple and I really wanted to create the same exact logic so we can easily compare both techniques here we go so I have my class right here on top of the class make sure that it is a blueprint type if you want to be able to access that function via blueprint you need blueprint type right here and then you also need a little meta right here the expose the async proxy equal async action meta that's just how it works this class requires to have that meta so make sure to add it otherwise it's just not going to work so make sure you have the meta and then your class is ready to be used here we go I have my class before adding stuff in the class though we're going to need another thing so I'm just going to create it right here we're going to need a delegate so declare Dynamic multicast delegate and then you name your delegate so in my case it's going to be fa async count seconds output pins because we're going to use that delegate to create all the different output pins we want to create on our function if you want five six seven output pins you're going to have to do it using that delegate right here so declare Dynamic multicast delegate and then the name of your delegate there we go that's it that's all we needed and actually I don't know why my visual studio is complaining about the micro but whatever just ignore that let's say that it worked perfect so I have my delegate and I have my class now that I have both of those I can finally create my function here we go I have my function right here as I said at the beginning of the video this function has to be a little bit different it needs to return a pointer to that class so here I'm going to create a function that returns a u async account second pointer because that's my class right here that we're going to create so this function the async account seconds that's the function you're going to call in Blueprint that's going to be its name but that function is not going to do anything it's actually just going to create an instance of that class and return it to the user and that's it the logic is going to be done elsewhere this function right here is really just to create an instance of that class and make sure that it is static so you're able to call it from any where obviously and then you can also provide all the arguments that you need inside this function so in my case I'm going to need the world context which we're going to initialize the same way we do usually so World context is equal to World context that's the name of my variable that I have right here and I'm going to assign it inside the world context property and then I'm also going to add all the other variables that I'm going to need to do my logic so in my case since I want to count seconds I want to first know at which interval I have to notify the user while counting my seconds so that's going to be my interval right here and then the final time when I should stop counting the seconds because I don't want to continue counting seconds forever I want to stop at some point so that's going to be the final time that I have right here and if you seen the last video you're probably noticing that I have way less variables right here compared to the previous one and that's simply because I don't need to provide everything inside this function because then that function is going to return us an object and then everything else can be accessed directly from that object that we're going to create create the variables on the side a little bit later so we're going to have an instance of that class we're going to have an object and from that object you'll be able to know the current time the status of the action if it's failed or not and things like that so everything's going to be saved directly inside the object you don't have to provide it to the function as reference for example here we go my function is created and it's fairly simple one last thing though just make sure that you have the blueprint internal us on equal to True right here that's going to tell unreal to treat this function a little bit differently than all the other functions and based on the context unal is going to do something specific with that function in our case since it's going to be a nnc action functions unil is going to create a latent node for us with the little timer icon and it's also going to add all the output pins that we need based on the delegate that we created at the top so if you want the function to be processed and generated properly you need the blueprint internal use only equal to True right here good I have my function but I still don't have the output execution pin and to create those well super simple you just have to create variables using the delegate you created at the top right here so the fa sync count seconds output pin delegate from that delegate I'm going to create four variables because I want four output pins I want the unupdated that's going to be called every time the timer is updated the uncancelled every time the timer is cancelled which should be only once actually the uncompleted when the timer is completed and unfailed in case that the action failed and as I said before I don't know why my visual St doesn't find my delegate right here it should find it and just ignore the red lines it should work good make sure that all those output pins are flagged as blueprint as signable so you can assign them in Blueprint obviously and that's it now you have a function and that function has four output pins there's just one thing that's missing and it is the function that's going to execute the logic of Your Action because this function right here is just going to create an instance of your object and return it to the user and start that instance but when starting that instance you want it to run some logic and that logic has to be inside the activate function right here that activate function is inside the parent so inside this class right here you have a function that is called activate and it's a virtual function so virtual void activate and we want to override it to be able to implement our own logic in our case I want to be able to count seconds and that's what I'm going to do using the activate right here we cannot start the logic inside the async count second that's just to create the instance then the activate is really to run the logic perfect so everything here is what's needed to create a async action blueprint node if you want to create your own async action you probably want to modify the variables that are receive as input and also the output pins but you absolutely need to have a function that returns a pointer to that class and also to override the activate right here otherwise it's not going to work and as for everything else that is related to my specific code we're going to do that right after because in my case I want to use this action to count seconds that's may be not something that you want to do so that's why I wanted to separate what's required and what I need for my specific case today so that's what's required and then if I scroll down all the way down right here I'm going to add all the variables that I'm going to need for my specific logic so to create my timer I'm going to need well first the timer interval that I receive as input I want to save it somewhere so a float timer interval right here another float the timer final time to remember when I should stop my timer then I want to have another float to know which time I'm currently at right now so timer current time and then I'm going to have a bullying to let the user know if the action is a success or not and finally an information message to give more information to the user in the case that the action failed or is progressing these are all the variables that I'm going to need to execute my logic and I'm also going to need another function right here the cancel count seconds because it's not possible to cancel the action directly on the Node it's not possible to add an extra execution pin as input to cancel our action that's why I'm going to create the cancel count seconds function function directly on my object I still have my object and it's going to work like any other object in unreal you can call functions on it so that's why right here I'm creating my little function void cancel count second I made sure that it is a blueprint callable function so I can call it from anywhere in Blueprint and that's it when creating my action I'm going to create an object and then I can use that object to cancel my action if I need to that's pretty much everything public I needed for my action but I also need some extra private function that we're going to use internally to end all the timer and everything so in my private category right here I have my update count seconds that's going to be the function called every x amount of time and we're going to use that function to notify the user that the timer was updated then we also have the Finish count seconds that's going to be the function we're going to use to clean the action once the logic is completed so if the user can Sol the action or if the countdown is completed this function is going to flag the object as ready to be destroyed and it's going to clean all the variables and make sure everything is cleaned up prop and since we want to be able to call this same logic in multiple places that's why I wrapped it inside a little function and finally I also need three little variables right here to be able to do my logic so I need the world context object I need the world and I also need a timer endle to be able to create my timer and that's it okay so everything right here is really specific to what I want to do in your case if you want to do something different all those variables and functions are probably going to be different obviously perfect so that's it for the other file now it's time to jump in the CPP and we're going to start with the includes and we have three of them today so we have the engine. H to be able to retrieve the world from the context object then we're going to need the world to be able to start the timer so I'm going to include my world. H right here and finally I'm also going to include editor engine. H that's something I forgot in the previous video so if your code in the previous video didn't compile it's probably because of that it's because I'm using the editor engine so the G Editor to retrieve the world that is currently open in the editor in the case that the world context object is not valid in my case since I'm not in game I don't always have access to a world or World context object so sometimes the world context object is not valid which means that I can use the editor to obtain the world that is currently open instead of using the world that is in game because I'm not in game so this is just for my test today you don't need to include that so don't worry you can use those functions in game no problem but in my case I'm going to use it so I'm going to need engine engine and unreal Ed let's go make sure that are in the build at CS file I have my engine right here and I have my unreal Ed all the way down there perfect I have all the modules I need now I can go back in the CVP if you're missing some you can just add them Obviously good so now we're back in the CVP and it's time to take a look at the first function the A6 count seconds function that's the function that the user is going to call in Blueprint and actually that function is not going to run the logic itself it's just going to create an instance of the action and then that instance is going to run the logic later on uh in my case my instance I named it the blueprint node because it made sense in my head I'm calling the blueprint node it's creating an instance of itself and then I'm using that instance to trigger my action but even though actually I'm just creating an instance of the action so don't worry about that I'm just creating a new instance of my action the UA snc count seconds I'm putting it into this little variable right here and there it is I have my pointer to my action now that I have my action I can provided all the variables that I receive as input so I have the world context that is all the way down here so blueprint node World context objects equal to for context I have my interval that I'm setting inside timer intervals right here right here I'm doing a Max just to make sure that the timer interval is not smaller than 0.001 F otherwise it will make a timer of 0 second and it will break the system a little bit so I'm just making sure that my timer is not equal to zero and then final time I'm just putting that variable inside timer final time just so the timer knows when it has to stop Obviously good I created an instance of my action I've set all the variables and now I can simply return my instance right here that's it that's all the function needs to do it doesn't do any logic it just creates the instance for you and then later on unreal is going to call the activate on that new instance so that's where the logic is going to happen inside the activate function right here so I'm going to scroll down a little bit and to do the logic in my case I want to trigger a timer so let's just do that to be able to create a timer I'm going to need the world because the time manager is inside the world so here I'm going to retrieve the world using the context object we receive as input so G engine get World from Context object the context object is going to be the world context object variable that we have on that instance and then if I didn't find a world using that context object I'm just going to return null and that world will be null in the case that the context object is not valid if the context object is valid and is inside the proper world that variable world is going to be valid Obviously good now I have a world but it's possible that it's not valid as I said so here in the case that the world is not valid so world is equal to null and also the time inside inside the editor so if G editor is not equal to null then I can retre the wall that is currently open in the editor and that's what I'm doing right here G editor get editor world the context get world and then that's going to give me the worldall currently open in the editor and that's it that's how I retrieve the worldall from the editor when I'm not in game if your code is only meant to be used in game you only need this line right here you don't need this little part right there but still possible that the W is not valid and in that case I'm just going to return right away because I don't want to do any logic for my timer I don't want to start a timer actually I can't because I don't have a world but since I can't I'm just going to return I'm not going to try to start a timer so if the world is equal to null then I'm just going to say that my action was not a success I was not able to create my timer because the world is not valid and when that happens I'm also going to trigger the unfailed pin so my delegate unfailed right here I'm going to broadcast it and that's going to fire the unfailed execution pin that is going to be on the blueprint node so the user can react when the timer failed to be created I'm going to set the state of my action I'm going to trigger the proper execution pin and then I'm also going to finish my action so finish count seconds that function is just going to clean up the action as I said before so I'm going to clean everything that needed to be cleaned and then I'm going to destroy my action because I don't need it anymore obviously because well I cannot run a timer and that was the only purpose of this action perfect so I'm going to set the state trigger the proper pin it complete my action and that's it I'm just going to return turn I'm done because I cannot do anything with this action in the case that I don't have a w perfect so now we handled the situation in which we don't have a valid world but if we have a valid world then it's time to start the timer and that's what I'm going to do right here in the world I have access to the time manager so get timer manager and then I can do a set the timer to start a timer for that timer I'm going to provide the timer endle which is the variable that I have in my action so timer and all then I have to tell my timer which function should be called when the timer is triggered and in my case it's going to be a function on this object so on this instance and the function that we want to call is update count second which is the function that I have right here so that function is going to be called every interval of my timer the timer interval is the variable I received as input so timer intervals right here then I have a bullying to tell my timer if we want it to Loop or not in my case I want to loop I want it to continue over and over and over until we finished counting the seconds and finally the minus one right here represent the delay of the first iteration of the timer in my case I don't want the delay I want it to trigger right away so I'm just going to put it to minus one and the timer is going to start as soon as we trigger it perfect now the timer is started and it's going to call update count seconds every x amount of time and it's inside that function that we're going to do the rest of the logic we're going to increment the seconds and notify the user when the timer is updated so we're going to do that right here I'm going to scroll down a little bit and inside update count seconds it's super simple we have to first update the timer so timer current time plus equal timer interval so we're going to increment it every interval and once that's done we can notify the user that the timer was updated so trigger the pin unupdated so broadcast that pin that's going to fire the blueprint code and once the blueprint code is run we can check if the timer was completed actually because now we just updated the timer and it now has a new time is that new time bigger or equal than the final time that we wanted to compare with so timer current time bigger or equal than a finer time if it's true well it means that the timer is completed we counted all the seconds we needed to count until the final time and that's what I'm going to say right here I'm going to say that it was a success my action is completed we counted all the seconds we needed to count and then I'm going to fire the uncompleted execution pin so uncompleted broadcast is going to fire that execution pin and once that's done we're done with this action the action is done working we did everything we needed to do in this section so I'm just going to finish my count seconds right here so it's going to clean up everything stop the timer and destroy the object after everything is done perfect so that was for the update count seconds and now we just have the two last little function right here and they are pretty quick so I'm going to scroll down a little bit when we want to finish the work we're going to want to check if the timer is valid so if my timer and all is valid and my world is not equal to null it probably means that I have a timer currently running in the time manager in the world and if it's the case I want to invalidate that timer I want the timer to stop running because with we don't want to have a random timer running in the world for no reason so in the world I'm going to get the timer manager again I'm going to clear a timer and the timer I'm going to clear is the timer and all obviously so this is just going to stop the timer that is currently running in the world the time manager and then I can also invalidate my handle so I don't try to cancel it again and again and again for no reason the timer is cleared once we don't need to clear it more times so I'm just going to invalidate my timer and perfect that's done the timer is cancelled good the last thing that we need to do when we want to finish our actions is to actually tell unreal that the action is ready to be destroyed so set ready to destroy that's a function in the parent of the action so all the actions need to call that function once they are done working you have to call this action if you don't unreal is never going to destroy your action you're just going to have an object floating around in space forever and that's not good make sure to always call set ready to destroy as soon as you're done working with that action the action task is completed the action was cancelled the action fail to run for some reason called the set ready to destroy and that's why I wrapped those two steps inside a little function because I want to make sure to always clear the timer and always call set ready to destroy when I'm done working with that action good okay the action is cleaned up properly and it's going to be destroyed it says set ready to destroy because on real it's just going to destroy it later it's not going to destroy it right away it's just going to destroy it on the next garbage collection call here we go that's it for the finished count seconds and now we have the last one cancel count seconds and that one is super simple we can see that it was a success it was cancelled by the user and then I can broadcast the uncancelled pin so uncancelled the broadcast that's going to fire the blueprint code and finally I can call my finish count seconds just to make sure that the action is cleaned up properly and the object is destroy and that's it now it's time to jump in unreal to see if it works and here we are in unreal and today we don't need a scene because everything's going to be inside the user interface that I have right here and actually yep it's the same as the previous video because that was the objective to be able to recreate the same exact logic with two different techniques so today it's going to be the async action blueprint node user interface which is similar as the previous one so I have my interval right here so at which interval we want to update the timer we have the slider for the final time so we can decide when is the final time of our timer a little number that is going to display the current time of our timer a button to start the timer a button to cancel the timer and finally a button to increase manually the timer and when we click on those button it's going to feed the information directly to our timer just like yeah okay the blueprint in this video is way more complicated than the one from the previous video yeah and that's because the async action count second right here doesn't do as much as the latent action in that node we cannot manage the current action that is currently running and that's mainly what caus all of that because I might have an action that is currently running and I don't want to spawn a bunch of different different instances of the same action I want to cancel the previous one before creating a new one but anyway let's go through all the steps together I have my function right here Asing count seconds that's good that's exactly the function we created it's a latent function perfect we have the little timer right here in the top right corner and we can provide the variables that we wanted to provide so the interval from my user interface and also the final time same thing from the user interface so the node knows what interval it should update the timer and also the final time of that timer when that node is called it's going to first create the action that I'm going to promote into a variable because I want to keep track of the current action and that's going to be the action I'm going to use to retrieve the current time or to cancel the action if I want to so I'm going to promote it into a new variable that I have right here on the left I have my new variable and then we have the thing that I like the most about this technique is that we have a little execution pin right here a default execution pin so even if we were not able to create the async action the blueprint code will not stop right here will continue using that execution pin that was not the case with the latent action the latent action will just stop right here and that's not fun so instead here what we can do is check if the action is valid and do something in that case but in our case I'm just going to always assume that the action is valid and that's it the node is just going to create the action for you and then execute the rest of the flow afterwards on top of that we have all the other execution pin that we created so the unupdated uncancelled uncompleted and also unfailed all the broadcast event dispatcher that we created here they are and that's just going to be used to update the user interface in my case if I just receed the unupdated I'm just going to update my timer in my user interface so I'm going to set my text using the current time of my action but if instead I receive the uncancelled completed or failed I'm just going to update the user interface with the information that my action contains and I'm also going to clear my variable because the action is completed the action should be destroyed in the near future so I also want to cancel my varable right here because I don't need to keep track of that variable anymore because it's cancelled or completed perfect that was for when we call this node right here but every time we call this node it's going to automatically create a new instance of theaction for you every time so if you call it 10 times it's going to create 10 intenses 20 time 20 40 40 intenses that can be a lot and it's possible that your previous instanes are still running then you can decide if you want to let them run and continue receiving the events for all those functions or maybe you want to cancel the previous action before creating a new instance and that's my case I want to be able to cancel the previous action before creating a new instance that way even if I spam the start button it's always going to cancel the previous action and then create a new one and when I click on that it's going to cancel the current action which is the little piece of code that I have right here so cancel current action is going to check if the current action is valid if it is I'm going to call cancel count seconds as simple as that that's the function we created in C++ to be able to cancel the action at any point I'm also going to do the same thing when I click on the button cancel timer because that's pretty much the same logic actually and I'm also going to do the same thing when the widget is getting destroyed because when the widget is destroyed it's also possible that the action is not completed it's still counting the seconds it's still running in background and if your final time is crazy high so let's say 2 hours 3 hours the timer is still going to run for another two hours and maybe you don't need that timer to run it's just going to run for no reason there's no widget to update there's nobody that is going to receive the event it's just a running timer for no reason and you don't want that you want to cancel the timer in the case that the object that created the timer is destroyed in my case I'm checking for the current widget but if you spawned it with another blueprint actor that actor can be destroyed and then you probably also want to destroy the timer you don't want to let it run for no reason so here that's what I'm doing evented destroy so when my widget is destroyed if I have an action running I'm just going to cancel before destroying the widget as simple as that and the last piece of code that we have right here is when we click on the manual increase button it's going to check if my action is valid because if it's not I cannot increment a random value on an action that doesn't exist that will not make sense and then since the variable are already accessible in Blueprint I can simply modify them right here so in my action I have access to the current time I can do a plus one on that current time why not and then set my timer using the new value that I want to assign to that timer and that's it that's as simple as as that the variables are accessible in Blueprint so you can simply set the variable hey that makes sense and after that obviously I'm updating the user interface because I want it to be updated as soon as I click on the button perfect that I think pretty much covers everything that we have in the blueprint right here as I said most of the logic comes from the fact that we cannot manage the current action directly inside the blueprint node we have to add extra logic around it to manage the current action but you can see it in a way that well you have more control over the things and maybe that's what you want perfect okay let's see how it runs now I'm going to run my editor utility widget it's going to open my little timer right here at the bottom and I'm also going to select it right here at the top so we can see what happens when we click on the button so I'm going to select my current widget here we go and then if I start my timer it's going to start the timer up the user interface and then it's going to update my text every time the timer is updated once the timer is completed it's going to update my us interface again to say that my Asing count second was a success and it's completed and then I'm also going to clear my variable because I don't need it afterwards I'm going to start again to see what happens I'm trying to cancel the previous timer but I didn't have one so it didn't cancel anything if I start again now it's going to cancel the previous timer start again cancel start again cancel so it's always canceling the previous timer before starting a new one and then it's updating all the way until the end and once it's done it's just going to say that it's a success and it's completed perfect it seems to work I can click on cancel it doesn't do anything because I don't have an action running I'm going to start an action and then cancel it there we go I was able to cancel my action and it say that it was success it was canceled by a user so that works I can change my interval right here so make them a little bit smaller here we go my timer updates faster I can increase the last value so the final time right here it's going to take more time to reach that final time obviously t t it gets to the end here we go it's completed and finally we can Min increase the timer right now I can't because I don't have a timer running but if I start a new timer I can increase it manually and here we go I reach the end and you can see that the final time right here is actually higher than the max time it's because well first the final time cannot be divided properly by the interval and that's why I have a bigger amount right here but if let's say I spam my timer super fast right here I'm going to go way above the limit because I'm able to actually spam a bunch of times in between the different updates actually I'm not that fast if I do that here we go I can go way above the limit before the next update is called because my intervals are too long that's something you have to manage on your side if you don't want the user to be able to go way above the timer value because right now I can spam it as fast as I can and it's going to go faster than the current time there we go perfect okay I guess that covers everything oh yeah no the distrct we forgot that going to start a new timer and now if I close this little widget right here it's going to cancel my timer and that's it it's going to make sure that the timer is destroyed because well the widget doesn't exist so the timer doesn't exist either so if I start my timer stop again it's going to start the timer before closing the widget and that's it now you know what to create a ning action with C++ and that's going to be it for today's video so I'm going to see you in the next one bye-bye
