Angle Between 2 Points In ActionScript

[BlueSin]

Yes this is probably a very stupid question, but I never paid attention in trigonometry. How do you find the angle between two points in ActionScript (Flash programming language)?

If you're unfamiliar with ActionScript, how do you find the angle between two points in general?

EDIT: I wasn't sure if this was the right sub-forum, since there isn't a 'programming in general' sub-forum.

Lol, since there is no 'programming in general' forum you should have just posted it in general discussion xD

lol here is how:

Xdiff = _root._xmouse-this._x;
Ydiff = _root._ymouse-this._y;
radAngle = Math.atan2(Ydiff, Xdiff);
this._rotation = int((radAngle*360/(2*Math.PI))+180);
angle = (this._rotation*(Math.PI/180));

-Edit-
Here is a flash I made a while ago messing with a code like that.

Or something a little more consolidated such as

var angle:Number = Math.atan2(y2 - y1, x2 - x1) * 180 / Math.PI;

Given x1 and y1 is "the point you're standing at" and x2 and y2 is "the point that you want to be looking towards".
