Well, this can become quite complicated since my entity is a 2D SPRITE... you see, I'm making a visual environment that resembles those console RPGs and some asian PC games where you have a 2D sprite as a character in a 3D world. So, it can be quite difficult to make the character move in a natural way using a physical engine that's designed for polygons... maybe I should resort to ent_move, oh well... it'll be hard to code jumps... ^^o
