Class Server

java.lang.Object
  java.lang.Thread
      tipgame.net.Server

All Implemented Interfaces:

java.lang.Runnable

public class Server
extends java.lang.Thread

This is used to receive and transmit data for consistency. The server is the authority of all information and all clients run in lock step with the server on a common clock. Upon a client connecting, the server sends:

1. id of the client as an int
2. keyboard array
3. mouse array
4. message array
   When the server starts running, at each frame advance it reads from each client:
   1. keyboard
   2. mouse
   3. message
   then it sends to each client:
   1. the timeInteverval as a double
   2. keyboard array
   3. mouse array
   4. message array
   The timeInterval is used to keep the clocks in sync. *
