Product Description
AI Game Engine Programming provides game developers with the tools and wisdom necessary to create modern game AI engines. It takes programmers from theory to actual game development, with usable code frameworks designed to go beyond merely detailing how a technique might be used. In addition, it surveys the capabilities of the different techniques used. In addition, it surveys the capabilities of the different techniques used in some current AI engines, and covers common pitfalls, design considerations, and optimizations. If you're having difficulty determining which techniques to use, or looking for working code best suited to a particular game, you'll find the answers here. You'll also find a clean, usable interface for a variety of game AI techniques with an emphasis on primary decision-making paradigms.

The book provides insightful coverage of a variety of subjects important to AI engine development, and ties them together masterfully to form an indispensable reference. Part I provides an overall look at game AI, covers the basic terminology used in the book, reviews underlying concepts of game AI, and dissects the parts of a game AI engine. Part II covers specific game genres (RPG, TRS, FTPS, Shooter, Sports, Racing, Strategy, Adventure, Fighting, Platform, and miscellaneous) and explains how they use different AU paradigms. It also covers the move common solutions to the problems posed by each genre. Some of the problems include, dealing with direct AI and human interactions, using scripting languages appropriately, and general intelligence/entertainment balancing. Part III provides the actual code implementations for the basic AI techniques such as finite state machines, fuzzy state machines, message board systems, scripted systems, and location-based information systems. And, Part IV covers the move advanced techniques, including genetic algorithms, neural networks, artificial life, planning algorithms, and decision trees. The book concludes with Part V, which looks at "real game AI development." The areas covered here focus on how distributed AI works as an overall paradigm that can help with the organization of any AI engine. There is also coverage of common AI development, debugging and tuning, and the future of AI.

After reading this book you'll have traveled through most of the huge landscape of knowledge that a game AI programmer faces, and you'll be prepared to master it!

Key Feature:
* Provides a detailed guide for programmers interested in creating an AI engine for and game genre
* Breaks down AI elements and solutions by genre, and provides concrete examples from popular games
* Includes code implementations for both basic and complex AI techniques
* Provides suggestions for how the AI systems discussed can be extended or optimized for space, speed, and other limitations
* Explains distributed AI as a paradigm that can help with the organization of almost any AI engine

On the CD-ROM
The CD-ROM includes all of the source code compiled using Microsoft Visual C++ 6.0, along with the compiled binaries; the GLUT wrapper for OpenGL library, and the Lua language library; useful bookmarks; and all the figures from the book.

System Requirements: Pentium 3.1 GHz or better, GeoForce Go or 3 graphics card or better, Windows (ME, 2000, or XP). The demonstration programs are written in Microsoft Visual C++ under the Windows platform, but only rendering is platform specific. The rendering API used is the GLUT extension to Open GL.

5.0 out of 5 stars Best game book I've read yet, April 15, 2005

By	Paul (Austin, TX) - See all my reviews

I have worked in the game industry for over 10 years, and have also taught classes in game design and programming. This is the first book that I would recommend as intro/intermediate textbook for game AI. It covers all the popular game types (shooters, fighters, sports, and more) and covers all the popular AI methods (state machines, scripting, messaging, many others).

The book uses a very clean, not-too formal, not-too conversational writing style, which is easy to get into and yet remains professional sounding. The included code is clean, usable, and is very representative of real working game code. There's also tons of code snippets from actual released games to show the reader how the concepts have been done out in the wild.

The book also goes into the actual process of creating an AI system for a game project. Only by knowing the type of game you're going to make, the platform, the audience, and a slurry of other factors can you intelligently design a system that will provide your project with everything it needs to succeed.

All in all, a great piece of work from an industry vet.

Also, another review states that "the book fails because it's OpenGL based," which is hilarious in its ignorance and outright falsehood. The reviewer states that "all major gaming houses use DirectX" which is strange, cosidering that the vast majority of all video games are actually not PC based (which is the platform that mostly uses DirectX; Sony and Nintendo obviously are not using Microsoft's libraries, even the XBox uses a very specialized version of DirectX). Plus the fact that the author actually WORKS at Sony, and you can see that the reviewer doesn't really have any clue. The book is about Game AI, and the small bit of OpenGL code in the book is just allowing a quick, cross platform "renderer" for the AI demos. This is not a book on game graphics, and never says that it is.

5.0 out of 5 stars All around great book on the subject, September 6, 2005

By	Anthony (New York) - See all my reviews

This book was quite revealing to me. It is basically split into two halves: the first part talks about specific game types and how developers have traditionally used AI systems for each, and the second part which covers the actual code implementations for these systems.
I loved the in depth game section. It was really interesting to find out exactly which techniques are used the the various games. He even includes many examples from real life games. It made thinking about creating these systems for myself seem much more doable.
As far as code goes, there's a ton of it. Both working game code for each type of AI system he's trying to explain, as well as code from real games or internet demos. I found his code clean and professionally written. I have already used code from three different chapters as a launching point for my own projects.
I saw a reference in another review for Programming AI by Example. I also own that book and I must say I liked this one better. Matt's book is good, don't get me wrong. But there's a whole chapter on math basics (which I didn't need), another chapter on steering behaviors (all of the information and code for which I can get directly from Craig Reynold's OpenSteer project online) and then specific chapters detailing Matt's own AI engine, which is called Raven (nothing really mind blowing, and I'd rather code my own to get the concepts solid).
Brian's book, on the other hand, was more of a toolbox of code that I can assemble into whatever shapes I need. Not too much code, and definately not too little. One of the reviewers noted that there's "not enough code to illustrate the concepts"? Sounds to me like somebody just wants the entire thing done for him. I looked at the other books that guy has reviewed, and he absolutely loved Andre LaMothe's "Tricks of the Windows Game Programming Gurus". Ha. That book is for total beginners, and was just a collection and republishing of some of his earlier, outdated books. He even says "I want to write like him".
I'm really looking forward to anything else Brian might write in the future. I have found so many useful nuggets of information from this book. Great job.

4.0 out of 5 stars Just What I Was Looking For, February 20, 2005

By	Joseph Cocovich "greybeard" (San Jose, CA USA) - See all my reviews (REAL NAME)

Up to now, I have discovered books that contained AI code samples but out of context for what I needed. The code was specific and merely a part of collections of examples. I finally found this book. It explains all the game genres in terms of AI capability and requirements albeit rather technical in some places that I appreciated as reference. I have not completed the book yet but the contents are allowing me to create my own AI Engine that includes all the types in the book. Just to gain experience and knowledge and add to my portfolio. I strongly recommend this book for both it's content and the CD contents. --Joe
