Direction formula?
I was wondering if anyone has any information on how to calculate the angle at which to rotate an object based on an x,y set of information?
Ie:
A circle has a point on it that I want to face the mouse. I have the x,y of the circle, and the x,y of the mouse. How can I figure the angle at which to rotate the circle?

Code:
atan2(mousey  circley, mousex  circlex)
