Not talking about the code, what I meant was the physics material ext..
Oh, this one. Honestly, I did not notice the need of using frictionless material in your game. It works fine. But if you check out mine, there is a little freze at the landing. It’s caused by undisabled friction. You don’t have this issue.
Maybe cause I'm using a kinematic body and not a rigid body, so I might end up needing frictionless material if I use a rigid body.
