3D movement for personage (Q3D)

Hello, lads!

I tried to use Oimo Physics, combine 2D movement with 3D and everything else. Nothing works properly.

If my game would be about some physic objects, that's perhaps would be enough, but no.

I'm trying to create movement for my personage. So, i need normal collapsing with solid objects and there should be no uncontrolled acceleration and bounciness.

Thanks for any help!

Rise!
