[Flash] Rotating an object to point to the centre.

Anybody know of a tutorial in Flash Pro 8 that helps me to rotate an object to point to the centre.

If not please could somebody direct me to a flash forum?

Here's some code:

Code:

---

onClipEvent (enterFrame) {
        GotoX = Stage.width/2;
        GotoY = Stage.height/2;
        DifferenceX = _x-GotoX;
        DifferenceY = _y-GotoY;
        _rotation = -Math.atan2(DifferenceX, DifferenceY)/(Math.PI/180);
}

---

I hope it helps.
