Calculate Simple Angle

[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:

Code:

---

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":

Code:

---

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:

Code:

---

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.
