Physics is a hot topic in computer games. No self-respecting action game can get by without a good physics engine, and the trend is rapidly spreading to other genres, including strategy games and puzzles. This growth has been largely fuelled by middleware companies offering high-powered physics simulation.Many high-profile games feature commercial physics engines.

But commercial packages come at a high price, and for a huge range of developers building a custom physics solution can be cheaper, provide more control, and be more flexible. Unfortunately physics is a topic shrouded in mystery, mathematics, and horror stories.

When I came to build a general physics engine in 2000, I found there was almost no good information available, almost no code to work from, and lots of contradictory information. I struggled through and built a commercial engine, and learned a huge amount in the process. Over the last five years I’ve applied my own engine and other commercial physics systems to a range of real games. More than five years of effort and experience are contained in this book.

There are other books, websites, and articles on game physics, but there is still almost no reliable information on building a physics engine—that is, a complete simulation technology that can be used in game after game. This book aims to step you through the creation of a physics engine. It goes through a sample physics engine (provided on the CD) line by line, as well as giving you insight into the design decisions that were made in its construction. You can use the engine as is, use it as a base for further experimentation, or make different design decisions and create your own system under the guidance that this book provides.
