This simulation shows us how an object (a translucent ball here) is controlled by four pistons. But , actually it is opposite of that . I mean, the piston shaft sprites go to the object and point towards a specific direction. You can also set a specific speed in the editor (I'd prefer not to use speed more than 40) Have fun- Scratch On =^..^=
I made to myself. It took about 3 hours( I didn't do it continuously). You can use if you give credit.(And please give credit, please ...) If you like it please love, share and comment.
