Don't see this as a problem, just accept it and 52 Part II: Moving Around Part II: Moving Around 53 embrace it; perfection is overrated! This lesson was learned in robotics thanks to the wave of nouvelle AI robots. After space has been figured out, it's possible to determine which parts are free space and which can be considered solid. This implicitly defines all movement: what is possible and what isn't. Only then can intelligent movement be considered. [ Team LiB ] [ Team LiB ] Types of Game Worlds It's surprising how many games rely on movement as their most fundamental concept.

This is an unavoidable consequence of current engine 44 Part I: Overview Part I: Overview 45 design, and can be difficult to deal with when starting out in AI development. This book provides a real game for testing the AI, and not just a toy environment or command prompt. For this, the open source FEAR project is used, integrated with a commercial first-person shooter game engine. Some other game engines use similar frameworks to assist the AI development (but they're not as flexible). FEAR provides some helpful facilities, including the following: • World interfaces for the AI to interact with the game engine (physics simulation and logic) • Modules that implement AI functionality on their own or by depending on other modules • Flexible architectures that enable engineers to assemble arbitrary components together • Tools to create animats and their source files using minimal programming As the combination of these elements and more, FEAR provides an ideal foundation for the examples in this book and many other prototypes, thanks to its flexibility.

Iterations These stages share many interdependencies, which is unavoidable because of the complexity of the task itself (just as with software development). It is possible to take precautions to minimize the size of the iterations by designing flexible interface specifications that don't need changing during the application phase. The final product of this process is a single behavior. In most cases, however, multiple behaviors are required! So you need to repeat this process for each behavior.
