The gems books are a little complex for a beginner, aren’t they?[/quote:f3e4d1c7e5]
You’ll find stuff for all levels in those, they are more like a collection of references than tutorial style books. They are expensive though and I don’t have my own copies, but I’ve read bits and pieces of some of them at work and they are pretty good.
Anyhow one book I’d definitely recomend for AI is (and juding by others posts on the Wordware books): http://www.amazon.co.uk/Programming-Game-Example-Matt-Buckland/dp/1556220782/ref=sr_11_1/026-1289302-7138866?ie=UTF8
I read this and learned loads. Maybe we should have a books section on this site where people could reccomend books!
