how to import AI code?

Hi. I just started to work on unity, and I made some parts of game, looks nice :). next step is to import some enemies, monsters etc. I have some AI code from star wars jedy academy but I don’t know how to import code or implement it with character. Do I need special type of character to import code to it, or I can use any character.

thank you.

first to import characters it must be in the extension .fbx and there is many sites that have free characters such as
link text link text
and also you can download from asset store characters and also you can download AI scripts
but i advice you to learn how to write a script, there is many tutorial to do that
