How to use Registration points to stretch and rotate a MovieClip Correctly

Question

Is kind of an explanation of what I am trying to do.

I have 2 known points, a slope, the angle I want it to rotate to, and the hypotenuse.

I've spent at least an hour trying different things, and googling.

Any idea on what I should do? Currently just setting the width larger, and then using .rotation.

Thanks.

use a top center reg point. assign your circle's x,y to match the upper point's x,y. then assign the circle's width and height to be distance between the two points and finally its rotation to be the atan2 between the two points:

circle_mc.x = p1.x;

circle_mc.y = p1.y;

circle_mc.width = circle_mc.height = Math.sqrt((p2.y-p1.y)*(p2.y-p1.y)+(p2.x-p1.x)*(p2.x-p1.x));

circle_mc.rotation = -90+ 180*Math.atan2(p2.y-p1.y,p2.x-p1.x)/Math.PI;

Thank You. That was exactly what I was looking for! Works exactly how I wanted it to.

One thing I removed the mc.width part, it was causing a large circle to be between the points. So I took that out and left it to default.
