Heya, I just uploaded Collision::Util 0.01 to CPAN. Like Kartik mentioned, it is still available only in pure-perl form, but it should do the trick for a while. Please report any bugs and/or feature requests you may have.
It currently expects any object with ->x, ->y, ->w, ->h value accessors (it only checks values and will never change anything), treating them as simple rectangles (y and x being top-left values). Functions are NOT exported by default. They are: check_contains() to see if the first rect contains the other rects check_collision() to see if the first rect is colliding with the other rects here, "other rects" can be either a single rect, an array reference of rects or a hash reference. The Pod documentation includes some examples and a much better description :-) Hope you find this useful!
