Looking for super nice work from past (2011 year)

Hello, I’m trying to find one superb nice work from far past. It was a collision example with a lot of orange circles, which user can touch and move. I attached a picture.

A trip down memory lane… by the right person.

It is probably easier if you implement the solution yourself at this point. There is sample code in this and previous forums about circle collision so no need to start from scratch. Then add the specifics… ask here for guidance if stuck.



It’s absolutely non trivial task to detect and handle a lot of collision at once. And it was super elegant and fast solution on 2d vectors.

Try using image search on your image along with “PVector” or “Box2D”
