OK, here I am with another issue... remember I finished my last thread in this forum telling I would use the physics engine to handle character movement? well, now that I'm about to to it, I realized I don't quite know how to achieve that kind of effect... so, does anyone out there know any resources, tutorials, or can offer a quick crash course in how to use the physics engine to achieve a natural-looking walking/jumping motion?

thanks in advance ^^
