I made this on accedent when messing around with turbowarp. I thought this would run terribly in Scratch, but it runs great! (No turbo mode needed) This works by cloning a bunch of balls that bounce with some effects to make it "roll".
And if you try spotting a pattern in the barrel, it preserves the design. So if you see inside, the go to block in the clone scrips can be inputted with mouse x instead of pick random. If you have ideas for me to code, be sure to comment below!
