Hey guys,
I'm trying to write a piece of code that uses the flob library to detect the movement of a person though a webcam. The motion detection captured interacts with random shapes that appear on the screen. When the shapes are "touched" they disappear and re-spawn off-screen as one of 8 random shapes through my changeShape function. I know where it's currently placed the shapes will continuously changeShapes. Can anyone tell me if I'm doing something wrong? Or guide me in the write direction to fixing this code?
Thanks!
