All Implemented Interfaces:

java.lang.Runnable

public class PositionLoader

extends SuspendableThread

The PositionLoader loads the current real world position for each Person from a server. If the file cannot be loaded, random positions are used and a message is shown. When the applet is stopped and started again, it tries loading the positions from the server again.
