It's weeks i'm attempting this on Scratch. I call the community help. Currently the balls are not pointing the direction they should cause its bugged as I see. How this should work: - the total momentum should not change. This should be a frictionless ambient. - the balls should repel each others - the balls should be able to bounce on the edge Thanks a lot! Feel free to remix! On the code there is also a special formula to get the angle between two objects made by me. If you use that please credit me, @Nick05
