Move the sliders and experiment! Space to see/not see the variables. If changing the variables hardly changed it, you must have done it too quick. I suggest moving the slider slowly to let it catch up to the variables.
Thnx to @PullJosh for https://scratch.mit.edu/projects/84486170/ . After I used it when making an engine, I always wondered how to get the shortest line possible between two ovals. Huge thanks to @Scratch_Minion for figuring out a better and efficient way to do this. I am trying to figure out a more efficient way but it is a slow process. (You may see the test variable script occasionally change.)
