I'm trying to figure out if there is any existing AI tools/frameworks/Library for Objective C or Cocos [well OpenGL + Obj C] in general that's good for a person who's never done any form of AI before [other than the simple checkers or tic-tac-toe AI's]. The scenario here is I've finished the basics control of a game for the iPad and works fine for multiplayer. The AI just needs to move around, similar to the classic game snakes and somehow 'trap' a human player. I now want to write an AI for this.
I found a thing called http://opensteer.sourceforge.net/ which appears to be pretty good, however, it was last updated in 2004. Which was 7 years ago, and I am not sure if I should use it if there are other ones.
If anyone has any other suggestions of things I should look at, please guide me to the right area.
