Question by Warbeard · Jun 09, 2016 at 02:53 PM · rigidbodygravity

Strange gravity using rigidbody on vehicle

Heya, I've included a video just so you can see what I'm talking about; basically the gravity seems to change all of a sudden.

https://youtu.be/PcGywYRnXCQ

I've moved the center of mass to slightly beneath the car to make sure it doesnt tip all over the place, yet I tried removing this and the issue persisted. I'm using Translate instead of AddForce because it feels more controlled to me.

rigidbody.centerOfMass = centerOfGravity.localPosition;
transform.Translate(0,0,speed);

Anyone tried this/have any ideas?

It's the translate. If you're using a rigidbody, and move it without force, it gets confused. It's expecting to move like actual physics, based on forces, so movement absent those forces causes some strange effects.

Also, I believe the transform.Translate you're using is in world space, not local space.

I think the issue is with the box collider - the first two are hit straight on, while the next is slanted, and that gets weird somehow.
