Coordinate Rotation and Bouncing Off Angles

Abstract

This chapter covers a particular technique known as coordinate rotation. As its name implies, this technique involves rotating a coordinate around a point. While useful all by itself, coordinate rotation is indispensable for several very interesting effects. One of those is the answer to a question that has continuously been asked on all the Flash boards for years: “How do I bounce something off an angled surface?” I’ll cover how to do that in this chapter.
