I've been weaning my son off of Scratch in favor of Racket, and trying to get him to write interactive games using universe.ss and image.ss. I'm wondering if anyone has suggestions for how to do things like collision detection. image.ss has these nice first-class images, but I don't see a good way of querying two images to see if they overlap.
Has anyone else had luck in doing this? universe has a nice programming model, but I've found it challenging to find simple ways of doing the kinds of things that Scratch makes easy. y ____________________ Racket Users list: http://lists.racket-lang.org/users
