2D Game Collision Detection · An introduction to clashing geometry in games

Are you wondering how 2D collision detection in video games works? If so this book is made for you.

Determine shot impacts, find out which enemies are covered by lines of sight, recognize collisions of race cars or simply check if the mouse cursor floats above a button.

This book is written for beginners, new to the topic of geometrical collision detection. It contains plenty of illustrations and code examples which make it easy to understand the necessary concepts and algorithms.

The book is also designed to serve as a reference guide for looking up specific collision detection functions. Therefore it is useful for advanced game programmers as well.

The code presented in the book is available for download. The according link is listed in the book's appendix.
