2D Physics, Pong ball is moving by itself!

I have a ball in a pong game I am making (start small, right?) :slight_smile:

The problem is, it’s haunted. The ball has been set with a rigidbody and collider (both appropriately 2D). So have the paddles, etc. I have set the gravity scale for the ball to zero.

If I start the game, nothing happens (as it should). However, if I move one of the paddles up or down, the ball will start to move on it’s own after a few secodns! In addition, sometimes the ball will stop at the physics collider on the top of the level, but other times it goes right through!

It never seems to go through the collider on the bottom of the level, even though they are identical.

Any assistance would be helpful, if you need the project file I can easily upload it as well.

Thank you.

Well, how about some ghostbusting?) Select your wall object turn on gizmos and hit play
