Calculate Simple Angle

[MichealStar]

[RESOLVED]
I've finally got it to work, just had to subtract the new angle from the moving MC(ball)'s current rotation.

So this is how it should look after being fixed:

onEnterFrame = function(){
	if(this.hitTest(_root.ball._x, _root.ball._y, true)){
		newx = _root.ball._x-_x;
		newy = _root.ball._y-_y;
		angle = (360/Math.PI)*(Math.atan2(newy, newx));
		_root.ball._rotation = angle-_root.ball._rotation;
		play();
	}
}

I've been trying to figure this one out for sometime now, I have seen a lot of posts in this forum on getting the right angle after collisions.

What I'm trying to do is get the rotation(angle) of a moving circle after colliding with another circle. I just want to do this simple and get the angle so that the moving circle just turns at the correct angle. No need to worry about acceleration/speed.

Here's my code as of now, there are two movie clips(two circles). The moving one is called "ball" and the other one is nameless.

Code in Movie Clip "ball":

onClipEvent(load){
	sp = 5;
}
onClipEvent(enterFrame){
	xsp = sp * Math.sin(_rotation*(Math.PI/180));
	ysp = sp * Math.cos(_rotation*(Math.PI/180));
	
	_x += xsp;
	_y -= ysp;
}

Code in the nameless Movie Clip:

onEnterFrame = function(){
	if(this.hitTest(_root.ball._x, _root.ball._y, true)){
		newx = _root.ball._x-_x;
		newy = _root.ball._y-_y;
		angle = (360/Math.PI)*(Math.atan2(newy, newx));
		_root.ball._rotation = angle;
	}
}

I know there has been a lot of tutorials and help on this similar topic guys, but I'm having problems with this. Any help is much appreciated.
