Making pong clone. Ball needs to have the same speed pre and post collision. The ball game object has a rigid body and a physics material. All friction/drag setting are set to zero, bounciness of the material is at 1 (All objects it interacts with also have the same material). The ball still loses speed after a collision, albeit very little.
Sorry if its a duplicate of my previous question, but for some reason I can’t find it via search and its not appearing under the questions section of my user-page.
