AI, or artificial intelligence, build a better game by directing behavior within the game that makes them more difficult, while artificial life, or A-Life, adding unpredictability of play and an environment that is more alive with game. This book discusses how easy and inexpensive to implement AI and A-Life in video games not only model behavior in the game but also create tools, generate code, and test the game during development. Examples of enhancements a few A-Life in the game are presented, and you will investigate? Trap potential use of AI and how to solve problems, apply A-Life for the game itself, the test A-Life itself and almost test using A-Life, applying AI and A-Life in a multiplayer environment, and much more.
