Ball collision

[Captain Planet]

Hi all.

I have a MC (a ball) with this AS on it:

onClipEvent (load) {
	left = 2 + _width / 2;
	right = 498 - _width / 2;
	top = 3 + _height / 2;
	bottom = 285 - _height / 2;
	xspeed = random(3) + 1;
	yspeed = random(3) + 1;
}
onClipEvent (enterFrame) {
	_x = _x + xspeed;
	_y = _y + yspeed;
	if ( (_x <= left) or (_x >= right) ) {
		xspeed *= -1;
	}
	if ( (_y <= top) or (_y >= bottom) ) {
		yspeed *= -1;
	}
}

This bounces the ball off each 'wall'. Can anybody tell me how to add more balls (using actionscript - ie not copying and pasting on the stage) and to make the balls bounce off eachother too?

Thanks.

OK, I've got hold of this:

which is pretty much what I want. I'm not great with the physics stuff, but can anyone tell me how to 'pump' more balls into the pack? Like a paintball gun, for example?
