This is a demo that uses the RectHit patch I was inspired to make after reading about a hit test method described by Bill Atkinson, after the recent release of code for MacPaint and Quickdraw.
The "RectHit" is used inside of an iterator to make a hit map. Complete score tally of all of the hit individual objects is aided by the Kineme Spooky patch.
The demo also uses the hit info to push blocks out of the way, make the star pop out, and create the color change and steam effect with the teapot, and creates a collision effect around boundaries.
