There's not really a good way to explain this, except its a pong variation.

Try it, and see if you can figure out whats going on Razz had my physics teacher entertained for a good 15 minutes

the controls are W+S, and Up+Down, and its 2 player only at this point.

Looks like an interesting idea, except the controls froze about 15 seconds in.

hmmm Neutral what platform was this on? I've heard one other report of people having trouble with the controls, but its worked fine on the XP and OS X computers I've tested it on, but java occasionally seems to have trouble with key input and window switching, but its not consistent between OSes.

here are the relevant pieces of the source in case anyone wants to take a look.



Code:
private boolean w, s, up, down;


Code:
w = s = up = down = false;


Code:
parent.addKeyListener(this);


Code:
ActionListener repainter = new ActionListener() {
     public void actionPerformed(ActionEvent evt) {
    if(s && angle1 > - Math.PI / 2) angle1 = (angle1 - (Math.PI / 45.0));
    if(w && angle1 < Math.PI / 2) angle1 = (angle1 + (Math.PI / 45.0)) % (Math.PI * 2.0);
    if(down && angle2 < 3 * Math.PI * 2.0) angle2 = (angle2 + (Math.PI / 45.0)) % (Math.PI * 2.0);
    if(up && angle2 > Math.PI / 2) angle2 = (angle2 - (Math.PI / 45.0)) % (Math.PI * 2.0);
    
    update(thecanvas.getGraphics());
     }
  };
  Timer repainttimer = new Timer(1, repainter);
  repainttimer.start();



Code:
public void keyPressed(KeyEvent e){
  switch(e.getKeyCode()){
     case KeyEvent.VK_S:
    s = true; break;
     case KeyEvent.VK_W:
    w = true; break;
     case KeyEvent.VK_UP:
    up = true; break;
     case KeyEvent.VK_DOWN:
    down = true; break;
  }
   }
   public void keyReleased(KeyEvent e){
  switch(e.getKeyCode()){
     case KeyEvent.VK_S:
    s = false; break;
     case KeyEvent.VK_W:
    w = false; break;
     case KeyEvent.VK_UP:
    up = false; break;
     case KeyEvent.VK_DOWN:
    down = false; break;
  }
   }
   public void keyTyped(KeyEvent e){}

The keys didn't freeze for me, but the blue (right) player is able to go all the way around via the bottom.

That's presumably because the above code has "angle2 < 3 * Math.PI * 2.0" as opposed to "3 * Math.PI / 2".

I tried it again, and this time the controls didn't work entirely, but the ball somehow managed to start orbiting the center.

nice, as in actual full rotations around? and how long did that keep up?
I'm completely baffled on the key input issue though. I'm gonna assume this under XP, but what version of java do you have installed? I want to see if I can recreate the situation somehow.

Cool, I like it :biggrin: . There's also a similar program for the 68000 calcs but without gravity.

I just uploaded a new version with rotation on the ball as well, *I* dont think it looks as good, but I had a request for it, if anyone wants to take a peek and let me know what you think, that would be great.


new version is Here (if you want the old version the old link still works)

cool! I've seen a similar thing, but no gravity, and a different scoring system.

how very odd, it worked fine on my friend's vista laptop today.

which version of vista, and what version of java?


I'm gonna guess my frame is not acquiring focus for some reason, although if its the active window it should....maybe the canvas is picking up focus instead.....I'll play around with it some when I get back to my development computer.




Liazon: thanks Cool

I have a 1-player game a lot like this on my iPod, but the object is to break bricks.

Breakout?

I have the latest Java from their website, and 32bit Vista Ultimate.

It's like breakout, but a little different. It's called Vortex.

alright new version uploaded, I've consolidated back down to one version, so original link.

I'm planning on adding a game startup window with some options, and hopefully an AI player.



will some of the people who were having key input problems test this now and let me know if it solved the problem?

The movement of the paddles is way too fast for me (it’s very difficult to control), the ball is much slower in comparison.

should the ball be allowed to move faster, or should the paddles move slower?

I noticed the same thing. I think the paddles should move slightly slower. It is hard to hit the ball sometimes b/c the paddle will move right past the ball. A different fix could be to make the paddles a tiny bit wider.

The S button doesn't work on Mac OS X 10.4.11 with the latest version of Java. It would be nice if the paddles were wider.
