Here's the link with the example and code:

Basically, what happens is that the ball follows wherever you click. I'm pretty new to actionscript, and I'm trying to break this down and understand completely how it works. I know all the terminology ie where variables are declared, functions, eventlisteners, math etc, but i don't understand how this values allow it to work.

For example, what's up with the variable "dx" and "dy"? Why are they 0 and if they are zero, then how come for the function "frame", the "minx" and "max" vars have Math.abs(dx/dy) added to it if dx=dy=0? Doesn't make sense. Thanks for clearing all of this stuff out.
