Summary

Game Programming All in One, Third Edition gives aspiring game programmers the skills that are needed to create professional-quality games. If you have a working knowledge of C or C++ and are ready to expand your skills into the field of game programming, then get ready to begin your journey with this latest edition! You won't cover the topic of programming in general, but rather the specifics of programming for games. Using the cross-platform Allegro game library, you'll learn how to write complete games that will run on almost any operating system. Both Windowsr and Linuxr screenshots are displayed throughout. Using the techniques taught within this book and the tools included on the CD-ROM, you'll be able to write standard Windows and DirectXr programs without the cost of an expensive compiler.
