It fist got stuck inside the moveable platform and when i moved it this happened (got stuck in the bottom and whenever i move the platform it gives me points.)
Oh, man! u.u I'm sorry. That error happened to me just once.
I changed some values on the rigid body 2D of the ball and the paddle, and it worked just fine. So, I thought I got it fixed. But I guess it didn't work.
Thanks for sharing with me this observation. I will be more careful on future projects.
