Mesh renderer, mesh filter● Information about this

model and shader used to draw it.

● Mesh Filter just stores info about mesh

● Mesh Renderer draws the model

Material, Shader

Rigidbody● Basic physics● Mass, gravity, forces● Collision handling

Collider

● Collision detection● Types: box, plane, sphere, mesh, capsule● Triggers

Scripting in Unity3DWhere the fun begins… :D

Using C# in Unity● Scripts are builded by Mono● Most of .NET functionality is available.● Delegates, properties, extended methods, LINQ, ...● You can use MonoDevelop or Visual Studio

About scripts in overall● Scripts are components● Each script is a class● Public fields are seen (and changeable) from

the inspector.

MonoBehaviour Class● Awake(), Start(), Update()● GetComponent<T>()● Instantiate()● Invoke()● Coroutines and “yield”● GameObject.Find()● OnGUI()

GUI● Current ways of creating GUI:

○ GuiTexture, GuiText, GuiLabel components○ OnGUI scripting○ … or buy a plugin :D

● New (way better) GUI system is announced. When ? Soon...

Some of Unity plugins● Touchscript - touch gestures● GoKit - “tweening” (moving objects)● NGUI - GUI creation● Marmoset - Image-based lighting● Photon integration - networking

ExamplesLet’s dive into scripts ;)

Q/Aflame wars ? :D
