Artificial Intelligence

Hi, does sb know of a good AI tutorial?

I need objects to find paths from place to place, and follow that path, and stop if there is any obstacle on the route. Cars should be able to move around an assigned road, and stop if sth is blocking the road.
If the cars are hit, they should move away.
I also need some cars/other objects to move towards the player.

I might be asking for too much, but I’ve been dreaming about these…

I’m new (but pls give some answer, and one suitable for me) and I do want to learn.

Learning basic pathfinding is the first step. Install this, poke at it, check out the source, and understand how to follow at least basic paths before tackling the more sophisticated topics like object avoidance.
