# How can I make bodies that do not stick to the wall in Bullet Physics? [duplicate]

Physics engine recommendation which can simulate pool game correctly?

I made a Billiards scene with Bullet Physics, but I've got a problem. When the ball is slowing down near a wall, it sticks to that wall and slides along it. It normally bounces, but at those low speeds it sticks instead of bouncing.

What's wrong? What should I set to make sure the ball always bounces when it hits the wall? I used barebone btRigidBody, with no parameters set.
