I'm trying to make a very abstract physics platformer with rigidbody movement. You essentially play as a wheel dolly. You know, those square platforms with wheels designed to move around trashcan and the like? Anyway, so the ideal is that you can roll around, jump and flip onto your back, and continue rolling around on your back. I've already got the jump and flipping physics all taken care of. However, even though I used a zero-friction physics texture on my rigidbody object, my player object can only move horizontally while in midair. I think because my object is a rectangular prism rather than a sphere, the friction is way stronger than it is in any of the physics tutorials. What would you recommend as the best way to get this rigidbody to slide around on the ground via physics?
