Alright, shy of some bugs that I can fix relatively quickly (hopefully), I got it working. Thanks guys.

P.S.: Can anybody tell me why I have so many -1's?

Where did you get the equation for dW? It's very difficult to dissect the entirety of this problem without knowing where the equations came from.

Are you saying that I can just use the x- and y-components to do the same thing? I figured it out but had to use a bit of trig... and the original method. XD

EDIT: ...Why the heck do I have like 7 -1's on this thread alone? (Not to mention they're my only -1's.) How am I supposed to report this?

Using angle/magnitude for vectors is almost NEVER the good way of doing things, it quite simply makes everything more complicated.

Unless you're planning on using non-right-angles for anything other than ramps... which I am. Also, nice oxymoron. ;)

EDIT: I see what you mean, definitely less trig involved, even for my above statement. I'll convert all my classes, and tell you how it turns out.
EDIT 2: Okay, how the heck to I program bouncing now? XD

I'm using angles because I'm using vectors and not keeping track of individual x- and y- axis motion, but rather speed in a direction. The use of angles also gives me the possibility of using angles other than right angles, e.g. 45- and 22.5-degree ramps. (I'm hoping to get to ramps in the future, but at the moment I'm only worrying about 90-degree angles; I'm just trying to write it so that it's easy to port later.)

EDIT: I forgot to mention the whole division thing: That's exactly what it is, and I can't believe I didn't realize that. I'll let you know if correcting that fixes the problem.

Thanks,

Selenaut

PS: I hate the quick edit feature. XD
