Mat Buckland has always rocked. His book AI Techniques for Game Programming is choc full of in-your-face AI implementations. He does not hide anything from you. Incredible book, the total opposite of so many failed attempts at actually coding up some working, useful AI that you can learn from. To this day I'm thankful to Mr. Buckland for such a terrific book. He's not afraid of showing you tons of code and I mean tons.
