Why doesn't my applet work on Mac?

[Jacob_]

This works fine for me on Windows, but someone with a Mac tested it and said that they just got a black screen, although they could hear their character moving. repaint() is definitely being called but it isn't doing it...

Strangely, on a Mac I have (it's an old PowerPC one with Java 1.5 and OS X 10.4), I get a black screen too but if I resize the browser window or move another window on top of it, it starts working.

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40   41   42   43   44   45   46   47   48   49   50

public void init() {         setBackground(Color.black);         log("Setting up");         //Initialize the canvas, set up input listeners        log("Starting animator");         animator = new Thread(this);         animator.setName("AnimatorThread");         animator.start();         new Thread(new Runnable()         {             public void run()             {                 setIgnoreRepaint(true);                 //load some stuff                setIgnoreRepaint(false);                 doneLoading = true;             }         }).start();     }     @Override     public void start()     {     }     @Override     public void update(Graphics g)     {         canvas.repaint(); //Updates a VolatileImage stored in the Canvas class        g.drawImage(canvas.getImage(), 0, 0, this);     }     @Override     public void paint(Graphics g)     {         update(g);     }     public void run()     {         log("Current thread is "+Thread.currentThread());         while(Thread.currentThread() == animator)         {             //Process input and so on            repaint();             try {                 Thread.sleep(8); //limit FPS            } catch (InterruptedException ex) {             }         }     }

I've tried moving code around between init() and start() and paint() and update(), no success.

Anyone see a problem?

Edit: Fixed some code that was copied incorrectly

Update: someone with Windows 7 had the problem too.

Why not put it online somewhere so I can test it and see what happens?

its from the cubic realms thread in the showcase, here is the link

its a good idea to call validate() at the end of you init code.


looking at your code, you should call it after your Thread has finished loading.

Here it is: http://1scripts.net/cubic/game.php?version=CubicRealms0.06_old.jar

After posting this I decided to try remaking the game as a JApplet with graphics drawn on a JPanel just to see what happened; here is the new one: http://1scripts.net/cubic/game.php

Although the loading screen didn't work on my Mac (it's an old one, maybe the loading takes so much CPU so the graphics thread is getting starved?), I didn't have to resize the window to get it to work, which seems like a good sign.

I had someone with Win7 test the JApplet version and it worked for them, although they hadn't tried the old version.

Works fine on my Mac.
