Hi Everybody,

I've been working on getting my paint synchronized as good as possible,
this is what I've come up with, can you think of something that would
work even better, let me know :-)

Kim Frederiksen

int currentTime;
int lastTime;
int appletSpeed=30; // Max wait time in milliseconds


public void start()
{
 startTime=(int) System.currentTimeMillis();
}

synchronized public void run ()
{
 while (true)
 {
  repaint();
  try
  {
   wait();
  }
  catch(InterruptedException e) { }
  currentTime=((int) System.currentTimeMillis())-startTime;
  sleepTime=(lastTime+appletSpeed)-currentTime;
  lastTime=currentTime;
  if(sleepTime>0)
  {
   try
   {
    spinThread.sleep(sleepTime);
   }
   catch(InterruptedException e) { }
  }
  lastTime=((int) System.currentTimeMillis())-startTime;
 }
}

synchronized public void paint(Graphics g)
{
     notifyAll();
}
