3. Networking

3. Graphics
Lights
- Using
- Cookies: Source, Size
- Shadows: Type, Strength, Resolution
Cast Shadow, Receive Shadow
- Performance: Vertex Lighting / Pixel Lighting, Hard Shadow / Soft Shadow
- Rendering: Linear / Gamma pipeline

4. Graphics
Cameras
- Perspective / Orthographic
- Frustum Culling
- Occlusion Culling
var firstPersonCamera: Camera;
var overheadCamera: Camera;
function ShowOverheadView() {
firstPersonCamera.enabled = false;
overheadCamera.enabled = true;
}
function ShowFirstPersonView() {
firstPersonCamera.enabled = true;
overheadCamera.enabled = false;
}

5. Graphics
Materials, Shaders & Textures, Movie texture

6. Graphics
public class PlayMovieOnSpace : MonoBehaviour {
void Update () {
if (Input.GetButtonDown ("Jump")) {
Renderer r = GetComponent<Renderer>();
MovieTexture movie = (MovieTexture)r.material.mainTexture;
if (movie.isPlaying) {
movie.Pause();
}
else {
movie.Play();
}
}
}
}

7. Graphics
Terrain
- Height tools
- Textures
- Trees
- Grass
- Wind zones

8. Physics
Rigidbodies
- Movement
- Is Kinematic
- Sleeping

9. Physics
Colliders
- Primitive
- Compound
- Mesh
- Convex Mesh
Use mesh colliders for scene geometry and approximate the
shape of moving objects using compound primitive colliders

10. Physics
Physic Materials

11. Physics
Triggers
- OnTriggerXXX
- OnCollisionXXX

12. Physics
Character Controllers
- cannot walk through static colliders
- can push rigidbody objects
- will not be accelerated by incoming collisions

13. Networking
- Multiplayer (HLAPI) (NetworkBehaviour, NetworkComponents)
- Networking infrastructure (TLAPI)

14. Networking
HLAPI:
Message handlers
General purpose high performance serialization
Distributed object management
State synchronization
Network classes: Server, Client, Connection, etc

15. Networking
HLAPI

16. Networking
TLAPI:
1. Initialize the Network Transport Layer
2. Configure network topology
3. Create Host
4. Start communication (handling connections and sending/receiving messages)
5. Shutdown library after use.

17. Networking
TLAPI:
// Initializing the Transport Layer with no arguments (default settings)
NetworkTransport.Init();
// Configure network topology
ConnectionConfig config = new ConnectionConfig();
int myReiliableChannelId = config.AddChannel(QosType.Reliable);
int myUnreliableChannelId = config.AddChannel(QosType.Unreliable);
HostTopology topology = new HostTopology(config, 10);
// Create host
int hostId = NetworkTransport.AddHost(topology, 8888);
// Start communication
connectionId = NetworkTransport.Connect(hostId, "192.16.7.21", 8888, 0, out error);
NetworkTransport.Send(hostId, connectionId, myReiliableChannelId, buffer, bufferLength, out error);
NetworkTransport.Disconnect(hostId, connectionId, out error);
