Résumé
Programming Linux Games discusses the most important Linux multimedia toolkits and teaches the basics of game programming, all in the context of real-world examples. The author starts with an overview of Linux gaming and then introduces the use of essential tools in the Linux development environment. Detailed discussions cover such topics as graphics, sound, and input programming; audio programming to get the most out of the major audio APIs; how to develop a powerful game engine and write a game in Tcl; the X Window System and its performance; networked gaming; and Linux game licensing issues.
