Great explanation! Thanks guys - I guess I will be creating another thread for drawing so that it doesn't interfere with the EDT while I'm at it.

Cheers  Smiley

I think it would be a good idea to have the camera actually following the turret's aim, instead of the edge-of-screen scrolling.

public class AppTest extends Applet
{
   Image i;
   public void init()
   {
   }
   
   public void paint(Graphics g)
   {
      i = createImage(this.getWidth(), this.getHeight());
      Graphics b = i.getGraphics();
      try
      {
         b.drawImage(this.getImage(new URL(this.getCodeBase(), "dude.png")), 0, 0, null);
      }
      catch (MalformedURLException e)
      {
         e.printStackTrace();
      }
      b.dispose();
      g.drawImage(i, 0, 0, null);
      repaint();
   }
}


But this doesn't draw anything:

   {
      i = createImage(this.getWidth(), this.getHeight());
      Graphics b = i.getGraphics();
      try
      {
         b.drawImage(this.getImage(new URL(this.getCodeBase(), "dude.png")), 0, 0, null);
      }
      catch (MalformedURLException e)
      {
         e.printStackTrace();
      }
      b.dispose();
   }
   
   public void paint(Graphics g)
   {
      g.drawImage(i, 0, 0, null);
      repaint();
   }
}
