lol, I was on the scratch yt page, and there was a tutorial for how to make gravity, then it said something like "so what would the scripts be to make a bouncing ball that turned?", so obviously this is super simple, so I made it. Press space to go to the basketball court they showed in the st video.
I made an updated version of it that is much better: https://scratch.mit.edu/projects/1287736906/
