gameprogrammer@xxxxxxxxxxxxxxxxxxxx: [gameprogrammer] Re: AI in gamesOK for 
your first questionsAI is used in so many places, basically AI is whenever you 
need the computer to "imagine" how it's going to do something, this can be:How 
to get somewhere (check the Dijsktra's algorithm or A* for basic pathing)How to 
beat the player in any game (be it the whole game (as an RTS) or a sub-game 
(like a battle in an RPG)What actions should a PC do in a certain situation 
(like for example if you jump at a ledge the character grabs on to 
it)etc.Notice that AI is not making one intelligence, it's making specialized 
algorithms that make seemingly intelligent answers, that's why it's 
Artificial.Games use all kinds of AI, when we understand that no one programs a 
whole "brain" and makes them do all sorts of things (with few exceptions) 
because that'd be too hard to make it run on realtime. Games use mostly 
specialized Algorithms, thought now we start seeing more elaborate decision 
making, where various algorithms put diferent weights on the decisions.Finally. 
A lot of people use LISP for AI, but I don't think that is the case in games. 
If you want to see some interesting thing research the next:Game Theory 
(Mathematics)Dikjstra's Algorithm / Floyd's Algorithm (Path making)Bayesian 
Decision Making (Probability/Programing) (Understand Bayesian Probability 
first)Inference Engines (checkout CLIPS)You may see how to use this on C++ or 
not, you maybe would want to make the AI with a script or such (because it 
needs a lot of tweeking). Hope that helps.
