if anybody has played the resident evil games, you may be able to help...

I know the advancement in how the game was programmed is beyond my abilities at this present time, but, where the zombies are placed and programmed, is that done by somthing called "EVENT PROGRAMMING?" it is somthing I am intrested in getting to know how to do, and another thing, do I have the title of the function correct, this type of programing applys to almost evrey game, or is it AI programming?

Any suggestions greatly recived!
