If you want to learn game AI, nothing beats this website:

Lot of people on the industry post on those forums. I don't know if the premium accounts are open or not, but the content they produce is well worth paying if you like game AI.

As for books, I think one the best ones to start is "Programming Game AI by Example", by Mat Buckland

There's actually a tool that automatically converts Python 2.x code to Python 3.x code:

http://docs.python.org/library/2to3.html

It works fairly well (things that I've translated with it have needed only minor tweaks afterwards to get them fully working again)

On a side note, noticed that 'code blocks' don't include support for either Java or Python. Since Elemental's AI dev is going to be in Python, it would probably make sense to add Python support to code blocks too.

thanks to everyone for adding to thread. here's a video discussing AI techniques in python:

Just a head's up, DiveintoPython3 has been finished and is available online for free or purchase.  Just the old www.diveintopython3.org and away ye go.

Useful indeed, Good find. 

This is kinda random, and outta left field as I've been very much out of the loop here lately  (come to me, Elemental capable PC in a month or so that I may start to help in beta land at last), but in regards to Python:

Will the recently announced moratorium and aim at a "grand catchup" in terms of the whole lot of it factor into Elemental down the line going BACK to the notion of aiming for Python 3.x versus what I last recall in a journal post a bit back of scaling back to 2.x due to maturity issues of a sort?  I can't speak yet with technical parlance, but here's the link to what I mean:

http://python.org/dev/peps/pep-3003/

Frogboy mentioned that due to poor support of Python 3.x in Visual C++ (one of many flaws, I can assure you), engine will work (ie. C++ will be exposed to Python) with Python 2.x. Will the game switch to Py3.x when the Visual reaches some maturity level?

That was pretty well my wondering, as the aim on the moratorium was to get everything caught up on the same page with a buffer of time (couple years they cite) and focus that was still only functioning proper back on version 2.5 and 2.6 and so on.

But even then, the trick may well be exactly when would the specific things Frogboy is eyeing would come into their own under 3.x and become something more than what they currently are under the old Python.
