I have an issue with the combat tutorial's ambush script as well, except that my orc enemy is already standing on the map, waiting, causing the battle to start before I even reach the trigger.

I've added the alignment scripts from the main file, the orcs alignment is already set to Evil NPC, the orc is global, the triggers are global, and they all have original names. Is there something else I forgot to do that's not in the video? Surely this script works for orcs as well as wolves?

I'm also wondering if it's possible to decrease the orc NPCs perception so the combat doesn't trigger so soon (sometimes I can't even see the orcs on my screen).
