use the sliders to edit the shape. press space to begin drawing (it will clear itself if you want to do a new one) press h to hide the variables press s to show them If you don't want to use complicated stuff just leave it at 1 (it controls how many times it loops around).
I made this project with some help from my "Coding for Beginners using SCRATCH" book. By the way I know you can edit the variables while it is drawing but don't do it too much because it can cause lag.
