    Default Applet loop problem

    hi, im a noob programmer but i understand something about java. I watched all the video tutorials about java gamimg, but now I want to convert the game into applet but i can't, specially because it doesn't support loops :S

    And if I use the method repaint() the FPS get too low...

     
       //Called when this applet is loaded into the browser.
     
       public void init() {
     
          addMouseListener(this);
          addMouseMotionListener(this);
          addMouseWheelListener(this);
          mess="press escape to exit";
          setForeground(Color.WHITE);
          loadImages();
     
            //Execute a job on the event-dispatching thread; creating this applet's GUI.
     
            try {
                SwingUtilities.invokeAndWait(new Runnable() {
     
                    public void run() {
     
                       startingTime=System.currentTimeMillis();
                      cumTime= startingTime;
     
                      timePassed = System.currentTimeMillis() - cumTime;
                         cumTime+=timePassed;
     
                         while(running){
                         update(timePassed);
                         updatePrisao( timePassed);
                         preso1.update(timePassed);
                         preso2.update(timePassed);
                         preso3.update(timePassed);
                         preso4.update(timePassed);
                          repaint();
     
     
                         try{
                            Thread.sleep(20);
                         }catch(Exception ex){}
     
                      }
                    }
                    }
     
     
     
                    );
            } catch (Exception e) {
                System.err.println("createGUI didn't complete successfully");
            }
     
       }

    That is waaay too much code to ask other people to read through for you, especially since you didn't really tell us what the actual problem is. Applets definitely do support loops.

    I suggest you narrow your problem down to an SSCCE that demonstrates what you're talking about in as few lines as possible.

    When it crashes, do you get an error? Why are you calling the sleep() method while on the EDT? That's a big no-no, and will cause your program to become unresponsive or laggy.

    I've asked you questions that you haven't answered and told you why your program is probably not working, which you've ignored. If you don't have time to read the rules, create an SSCCE, or even respond to help you're receiving, why should other people take their time to help?

    I recommend you read the link in my signature on asking questions the smart way before you post again.
