WheelCollider climbing the wall

Questions & Answers
1

Hello! Sorry for broken language :slight_smile:

I’m trying to make arcade car model and experiencing an issue with its wheels.

Simple car model with normally oriented wheelcolliders.
Simple track surrounded with borders.

I want my car on colliding with wall just slide along it (if angle of impact is appropriate), but car climbs on it.

I’m happy with car movements and physics on flat space but when car model colliding with wall - it climbs up. I’m not talking about head-on impact on huge speed. Even on low speed if drive along a wall and collide with it.

I’ve tried to play with physic materials of wall and car colliders (Friction). Even friction=0 on both solids. No luck.
I’ve tried to make car collider wider wheels base - unacceptable due to weird behaviour while jumps/collides and anyway it collides at strange poses.

On attached image you can see boundaries and center of mass.

I tried all of obvious things but suppose that I missing something.
Thanks for any advice!

Seems I found some workaround for this. First of all, issue is not connected with WheelColliders. It turns out that boxcollider of vehical just forced to climb by velocity. It’s weird, cause issue is happen even at very low velocity.
I’ve just created a physic material with huge negative friction direction and applied it on the vehicle. Now seems much better, but not so good, as I want :slight_smile:
