Use the slider to turn on (1) and off (2) collisions. You can use these scripts however you want. there is no objective whatsoever. With collisions on, you bounce around when you touch a red and white circle. With them off, you can pass right through them. Backdrops and speed can also be altered when variables are on. The green ball will try to follow your mouse pointer when it hits the walls. V to turn on and off variables (show/hide) M key to turn on collisions with mouse pointer. This has a really simple code and is really not that hard to remix. So if you want to remix this project, just do it. se give me any ideas for updates in the comments section. This is one of my favorite projects now.
