This is my collision detector behavior class:
public void initialize()
{
wEnter = new WakeupOnCollisionEntry(tg);
wMove= new WakeupOnCollisionMovement(tg);
wExit = new WakeupOnCollisionExit(tg);
wakeupOn(wMove);
System.out.println("init");
}
Should I be getting the processStimulus event to run continuously if the
object of concern is already overlapped initially?
Thanks.
