I tough I could learn something about AI so I tried with blizzards campaign map. I extracted "Human02.w3m" (second human campaign from RoC) from war3.mpq and in "Scripts" folder I found h02_red.ai (ai script that controls Orc attacks in that map). The problem is I can't find a connection between the two. I couldn't find a trigger that loads h02_red.ai and if I delete that script from war3.mpq the Orcs don't attack anymore. How does the map knows that it has to use that script if it is not stated in triggers?
