Presentation about Unity3d engine.

2. Unity3D - What is this ?
● 3D game engine (recently also 2D)
● Graphics, physics, sounds,
● Works for any type of game.
● Scripts written in C#, JavaScript, Boo (? :D )
● Desktop, mobile platforms, consoles,
webplayer

3. Advantages of Unity3D
● Indie version is free
● Supports DirectX9, DirectX11, PhysX
● Easy to learn
● Enormous support of community

7. Briefly about Unity3D
Components

8. Transform
● Position, rotation, scale
● Part of every gameobject, info about hierarchy
● All sorts of translations, rotations etc. in scripts

9. 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

10. Material, Shader

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

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

13. Light

14. Types of lights in Unity
Point light Area lightSpotlightDirectional light

15. Particle engine

16. Scripting in Unity3D
Where the fun begins… :D

17. 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

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

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

21. 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...

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

23. Examples
Let’s dive into scripts ;)

24. Q/A
flame wars ? :D
