Thanks, getting it to change from a cube/sphere is working.As was stated though, I'm getting the cube penetrating objects that the sphere wasn't on creation.I'm unsure on how to detect the depth of penetration and move the cube by this amount, any pointers please?Thanks in advance.> Date: Tue, 12 Sep 2006 10:33:38 -0700> From: hplus-ode at mindcontrol.org> To: tias_dp at hotmail.com> CC: ode at q12.org> Subject: Re: [ODE] Sphere to Cube?> > The easiest thing to do is to remove the sphere geom from the body and > destroy it, and create a new geom that's a cube and attach that to the > body.
