[...] could do immediately is rotate one object to face another (or the mouse) by using a function like this one to get the angle between the objects in radians, and using displayObject1.rotation = rotFromRad( [...]

Thanks, Hanox! More to come …

Worked for me when I changed it to this:

public static function findAngle(point1:Point, point2:Point):Number
{
var dx:Number = point2.x – point1.x;
var dy:Number = point2.y – point1.y;
return Math.atan2(dy,dx);
}

In livedocs I found:
Note that the first parameter to atan2 is always the y coordinate.

Anyway thx for the Helper classes!
