Question by siege911 · Jun 20, 2012 at 09:55 PM · physicsbounce

Bouncing not working

I'm trying to simply make an object bounce and it's not working.

I have a simple cylinder (my "ball") and large cube (the "ground).

Ball has... Rigidbody with Mass of 1, and Angular Drag of 2 and uses Gravity. Custom Physics Material with Dynamic and Static Friction of 0 and Bounciness of 1 (I've also tried the default "Bouncy" material).

Ground has... Rigidbody with Mass of 1 and All Constraints Frozen so it doesn't move. Custom Physics Material with Both frictions at .4 (though I've tried 0 also) and Bounciness of 1. I've also tried it without a Physics Material.

My little script launches the Cylinder Angry Birds style and when it hits the cube it doesn't bounce at all. It just rolls to a stop. I need it to bounce. Am I doing something wrong or missing something?

There;s a minimum bounce velocity setting in Physics settings... Maybe that

Thanks for the tip but unfortunately that didn't fix it.

What types of collider?

Ground has a box collider and cylinder has a capsule collider.

Well the ground doesn't need a rigidbody - just a collider - but I'm not sure why that would be your problem.

Actually giving your ground a rigidbody is your problem (I just tried it). If you were to give it a rigidbody then set isKinematic = true - but you shouldn't need one.
