Using vanilla mathematics:
var from:Point = new Point(100, 50); var to:Point = new Point(80, 95); var angle:Number = Math.atan2(to.y - from.y, to.x - from.x);
Using a new vector representing the difference between the first two:
var difference:Point = to.subtract(from); var angle:Number = Math.atan2(difference.y, difference.x);
atan2()returns radians, not degrees.
