Hey, cool. When did you get the domain name?

BTW - love the sounds you put to 'Pong', they cracked me up. :-)


I've had it for a while but I linked it up a couple of months ago.

I told Jeff Higgins, my wife hates the sounds and leaves the room whenever I play the game :-).

I got a little bug while playing. When the ball hits an upper corner more or less exactly (depends on speed), it stays glued to the top line. This is because the following Y condition

// if ball is hitting top bounce off
} else if (ballY <= 0) {
veloY = -veloY;
bink.play();
}

Should not be "else" to the X condition.

If the ball crosses both conditions (X&Y) in the same step, the veloY will be added twice to ballY before the Y condition is evaluated and so the condition (ballY <= 0) will now be true forever (with the veloY changing sign at each frame).

So take out this "else".

:-)

Fixed! It still has a few other little bugs. Feel free to recommend fixes.
