18. Setting Up Bone Animations The Model Abby has different animations: Idle: 1-200 Idle: 201-390 Idle Action: 391-660 Walk: 819-898 Etc. We need to split animations to use them in Unity Getting Started with Unity
19. Creating Prefab Create a New Scene File -> New Scene Add Plane and scale it bigger (x & z) Rename “Abby” to “Abby Model” (project view) Create Abby prefab Project Popup -> Create -> Prefab Rename “New Prefab” to “Abby” Drag-and-drop Abby Model to Abby Getting Started with Unity
20. Creating Prefab Adding control scripts to Abby Drag-and-drop ThirdPersonController to Abby Change values of CharacterController of Abby Height: 1.7 Radius: 0.3 Add animations to the scripts Add SmootFollow to Main Camera Drag-and-drop Abby to Scene view Make her stand on the plain Drag-and-drop Abby to Main Camera/SmoothFollow/Target Getting Started with Unity
23. Adding New Animation Control Create new C# script AbbyAnim Attach the script to Abby (on Scene view) Add idle action animation clip to the Abby/AbbyAnim Apply changes to prefab Getting Started with Unity More about character animation, http://unity3d.com/support/documentation/Manual/Character-Animation.html
24. public class AbbyAnim : MonoBehaviour { private Animation _animation; public AnimationClip action; void Awake() { _animation = GetComponent(typeof(Animation)) as Animation; if (! _animation) { Debug.LogError(“…”); } if (! action) { Debug.LogError(“…”); return;} _animation[action.name].wrapMode = WrapMode.Once; } … Getting Started with Unity
25. … void Update() { if(Input.GetKey(“z”) { _animation.Play(action.name); } } } Getting Started with Unity
26. Mono Behavior Can be attached to game objects Unity Calls MonoBehavior Initialization Awake(): called for every MonoBbehavior Start(): called for every MonoBehaviour after all the Awake()s Game Loop calls Update(): called in every frame, most things happens here LateUpdate(): called after every Update()s are exceted. Use for, e.g., follow camera FixedUpdate(): use for physics thing, e.g., RagDoll handling OnGUI(), for GUI drawing, can be called several times in each frame Other useful things: Invoke(), InvokeRepeating(), StartCouroutine() Getting Started with Unity
27. User Interface public class ExampleGUI : MonoBehaviour { public GUISkingSkin; public string infoText = "”; private boolshowThingies; void Start() { if(gSkin==null) { Debug.LogError(“ gSkin is not set”); } showThingies = false; } } Getting Started with Unity
28. User Interface… void OnGUI() { GUI.skin = gSkin; // Seting skin for changins how GUI looks in inspector GUI.matrix = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, new Vector3(Screen.width / 1280.0f, Screen.height / 854.0f, 1)); GUILayout.BeginArea (new Rect (1100, 750, 100, 100)); if(showThingies) { if(GUILayout.Button ("Hide")) { showThingies = !showThingies; } } else { if(GUILayout.Button ("Show")) { showThingies = !showThingies; } } GUILayout.EndArea (); if(showThingies) { GUI.Label(newRect (600, 400, 200, 200), infoText, "blackBG"); } Getting Started with Unity
29. User Interface Create a game object for attaching GUI script Game Object->Create Empty Rename the new object to, e.g., GUI Cube Drag-and-drop ExampleGUI script to GUI Cube Create GUI Skin Project -> popup -> GUI Skin Drag and drop the skin to ExampleGUI : GSkin Getting Started with Unity
30. User Interface Experiment with GUI Skin settings Play to see how the settings changes GUI Getting Started with Unity
31. Models and Animations Characters 15-60 bones Hierarchy! Consistent naming (the same names for same type of things) 2500-5000 triangles Textures Optimal size: 2nx2m (1x1, 2x2, …, 128x256, … 256x256, …, 256x1024, …, 1024x1024,) In some cases SoftImage does texture optimizing Optimal size: small as possible Older cards do not support over 1024x1024 Getting Started with Unity
32. Material – Shader – Texture Material defines Shader Defines method to render an object, texture properties, etc. Texture(s) Color definitions Other assets E.g., cubemap required for rendering Getting Started with Unity
33. Models and Animations Object needs to be drawn for every of its texture Object with 4 textures will be draw 4 times Combine textures in SoftImage Use different textures only if you, e.g., need different shaders Unity and SoftImage have different shaders Use simplest possible shader in Unity Opt for shaders without bumbs, transparencies unless you use these Getting Started with Unity
34.
35. Version Control External version control with Pro Needs to be enabled from Edit->Project Settings->Editor Set up the system: http://unity3d.com/support/documentation/Manual/ExternalVersionControlSystemSupport.html CVS, Perforce, Subversion, … Binary files, (textures, models, sounds) do not work work well with these Unity Pro project will be incompatible with Unity DropBox as version control Drop the project folder to a DropBox folder to check in a version and vice versa CVS, Perforce, Subversion for version control for scripts Unity and Unity Pro projects will be compable Unity Pro only features will be automatically disabled in Unity Regular backup (e.g., zip the project folder) Archive backups to have snapshop of the project to rollback Getting Started with Unity
36. Terrain Editor Terrain->Create Terrain Getting Started with Unity More about Terrain Editor, http://unity3d.com/support/documentation/Manual/Terrains.html

Editor's Notes
Unity Project in the filesystem is a folder that contains folders Assets, Library, and Temp. Models, textures, scripts etc. goes to Assets folder. Assets folder can contain subfolders. Just drag and drop in Finder assets were you want to put them.BUT, rename things in Unity, NOT in Finder, because renaming in Finder will break dependencies in Unity.
Test by hitting PLAY. You can test and see your game in Game window . Controls: ASDW or cursor keys + mouse
By default, as Play Automatically is selected, the animations of the model are played, but we do now we do not have any control over them
