In ActionScript 2, you had the watch function that, among many things, allowed you to detect which direction your mouse cursor was moving. There is a [tutorial](http://www.kirupa.com/developer/actionscript/detecting_mouse_direction.htm) on how to do that on kirupa.com itself. In ActionScript 3, I couldn�t find the watch function nor an equivalent replacement, but creating your own function that shows you how to detect the direction of mouse movement is not very complicated.
