new characters as you can see I've created for this video two characters the first one named Alice which we met at the beginning of this video then we met the Furious of the Oracle inside the cave you can see in the basic information you can set the name of the MPC character the traits the role in the game the stage of Life any alternative names to call this character hobbies and interests even if you can link it to Wikipedia if this character is real one and have an old history in the chord description you can give a general description of your character in the game so this description I got generated through charge EBT so Alice is cute and funny I just put General traits and chatibility generated for me this core description so Alice is a funny cute girl full of energy she's always cheerful and optimistic and something like that you can also mention the flows of the character so what this character afraid of or what the things that she is not good at for example I wrote here Alice is afraid to be alone after the loss of her parents another thing to add is that the motivations of your character so for Alice it's she is motivated by her desire to explore and have new adventures she is always looking for excitement and love discovering new things you can choose also the dialogue style they want it bubbly formal blunt commanding empathetic entertaining laid-back sarcastic and a lot of other dialogue Styles next you can put some dialogue examples some sentences that you want to mention or to try to keep the dialogue around them and finally you can choose the voice of your character if it's masculine feminine what is the age useful old middle aged and there are tons of voices that you can try of them so once you choose the voice you can listen to it I'm Alice you can choose another voice you can change the talking speed and Pitch to get different variations of character voices and now if we go to the advanced tab here we can specify more details about the character personality and mood so here you can determine what is the character traits by adding some main characteristics like funny kind-hearted introvert extrovert anything you imagine so in the mood you can control the character Mood by dragging these sliders between two values here it represents the sadness and joy the anger or fear disgust and Trust anticipation or surprise static emotion or dynamic static relationships or dynamic and for personality we can determine whether the character is positive or negative peaceful or aggressive cautious or open introvert or extrovert insecure or confident additionally here you can determine the knowledge of the character so it can realize the environment around it or any other characters to communicate with it or tell something about specific character or location here I mentioned that there is someone called zephyrus lives in the cave near the waterfall and that's how this character knew about the other character next we have the goals which triggers some context when something happened in the conversation so when the player tells some information we can trigger something in the game like open the door or next Quest or something by that I'll not go into details because this require a full detailed video about this Gold's feature and finally you determine this character in which Scene It exists and for that you need to go to the scenes section and create a new scene to describe what is this scene so you need to put the name of the scene in my case it was a fantasy forest and here is a simple description what is this scene about and this will help the character to get some information about where it is and what it's talking about so in the description here we are in the bright fantasy Forest where Alice and zephyrus lives the wise Oracle the Furious lives in the cave next to the waterfall so this gives additional information for your characters and now your character is ready to be imported to any other game engine or any supported games so you can import to Unity engine unreal Roblox Minecraft ndk node.js so we will test the unity integration once you click on Unity you will get the inward tutorial about that so you can go to the unity asset store and add the AI MPC engine dialogue and behavior for Unity inward you add it to your assets once you add it to your assets you go back to Unity to your Unity project which uses the built-in renderer go to the package manager and then choose my assets check for in world and import okay once in World Imported correctly you will see that there is a new tab called in world then you go to the studio panel and also the in World requires the text mesh Pro essential resources you can import that then you click on login and go back to the website click on integration you might need to use the API keys and the secret but you need also to generate Studio access token click generate copy the code go back to Unity paste it and click login it will welcome you then you need to select the work space I created already workspace called binary lunar then I'll choose my key and the in-world scene it will load your characters to Unity editor once you've finished loading you will see the characters inside the selected scene so we have Alice and serious if you click on Alice you'll see its prefab in the project files and simply you can drag it to your scene and you have the character ready to be interacted with if you don't want to create your own controller you can simply add the player controller to Unity scene and that's it now we are
