I was following a tutorial on how to make ping pong (https://www.youtube.com/watch?v=Xq9AyhX8HUc) but at around the 16 minute mark, he runs the game and the ball works perfectly, but mine doesn’t for some reason. It freezes and doesn’t move.
I recommend you rewatch those 16 minutes and see what you missed. We don’t have your code, and I doubt anyone else is going to want to watch 16 minutes of video and then guess at what you might have missed.
If you’ve done that already and are stuck, show us a screenshot of the editor and how the node structure looks, and then the code for the ball.
