How to remove previous shape after draw() in Processing

Question

I cant figure this out. I have a sketch with little rotating rectangles on it. They rotate on every draw(). However the previous rectangle remains visible. I tried moving backgr

Answer 1

What you are doing is printing every single circle or line...ect. You need to have a timer that removes them every so often. If you do it too fast you get a strobe like look. So have a timer that removes the first rect from the array list every so often.
