A quick ball related issue.

Aug 8, 2009 at 12:09 PM

Hello, I'm trying to create a platformer. On my way there I've made a character that is for now.. a ball. Problem is, I can't get it too move.

to attempt to move, I apply torque to the ball. However, it doesn't seem to work.

The ball is indeed rotating, but is not moving. All it does is bounce on the same position (the higher the torque, the higher its vertical speed goes, no horizontal speed whatsoever).

I understand that the problem is friction-related, and that the ball bounces on the spot because it is not a perfect circle, but I'm going wrong somewhere.

What kind of friction do I need to apply to both the ball and the floor for it to move? I tried nearly everything.

Thanks in advance!

All this time I had applied the friction to the body instead of the geometry. Problem solved.
