hello community! im new to processing and im having tons of trouble with it. my teacher sent us an assignment last week about the first chapter of this  http://blabla.nfb.ca/#/blabla. i can make the ball move around the window but i have no ideia how to split the ball when you click on it and how to group them when they touch. you would ask " why dont you ask to your teacher?" well he's a jerk, he doesnt teach us jack, he doesnt give us exercises to practise neither examples so we can actually learn something. the only thing he says is " go google it." and its getting really frustrating. if anyone could give me a tip on this i would be eternaly grateful.
