I'm trying to make a rolling ball game, and I need to know how to write a script that uses collision detection. I also need to know if there's a way to add other modules to pythonista, specifically tkinter.
Go to http://omz-forums.appspot.com/pythonista and search on "collision"... There are many discussions on this topic.
On tkinter, see http://omz-forums.appspot.com/pythonista/post/4586664294875136 for a discussion on why this would be a difficult task.
