non-spherical collision

is there a way to change that collision sphere blender has into an oval, cube, rectangle, or some other shape?

ODE <<— maybe,i didn’t exactly use it…

the movie looks nice, excpe i have a tiny problem, and that is tohupuu 2.25 doesnt have a working engine(on my computer only, probably). you can start a game, but it doesnt respond to anithign except esc, and nothing moves.

In tupohuu you have to set your game engine mode or it wont work at all. Go to the world settings, make sure to add a world, and set the engine to ODE or enji. For enji to work, you have to make a sector to put all the objects in.

ode just moves around my ant.

heres the file, incase you wanna see how screwed up it is.
