TRSCollisionMap Readme
In this readme, we discuss performing 2D collision detection using the TRSCollisionMap class, a free class with source code (available at www.RiverSoftAVG.com/Files/RSCollisionDetection.zip ). For a certain class of problems, this class provides easy and fast collision detection for 2D games.
We certainly don t claim this class is perfect, or that there are not better methods. But for a certain class of problems, this class has the advantage of being simple to use and accurate. Plus, it s free :-)
