up ?
Sorry but i have no answers, anyone know how setting the density when you have moment of inertia ?

Good Morning,

I have to do the same project than dark and I think the moment of inertia is linked with the density but on chipmunk, I don't know how to use the density too.

We have to finish the project the next monday morning and we need help to solve this problem.

Sorry for my bad english thanks for your future help.

In Chipmunk you set the mass of a body rather than the density. You set it with body->m. If you only know the density you'll have to work out the mass from the size of the shape.

If I understood, the density is useful to obtain the mass when whe don't know it.

thank you for your help.
