Hello,
I just try to test the benefits of ODE, and once initialized, now I try to manage collision, and see the effects of ODE.
I declare my geom, my space, autocollide… But nothing happens. It seems to be close as I can see on tutorials, and other post, and I think I need someone else to look at my code, and see the error I can’t see.
