No I don't mean an area script. If I wanted to use Area scripts I would have to append my code into every single outdoor area script where I wanted it to happen. Not that it's not undoable, but there should be a more elegant of doing it.
As we know, AR0700.bcs and AR0300.bcs are area scripts in the city. However the occurences, say (for those with bad reputation) "Guards approach. (blah blah)" and about 5 Amnish Legionaries and 2 Cowled Enforcers suddenly reasonably appear near you, are performed using AmnTrp01.bcs. If one were to look over the code one would find that whatever thing uses AmnTrp01.bcs, should be an item or an actor, since it spawns the Guards etc based on the position of the invisible item / actor, where the invisible item (usually as a condition in the trigger) is within range 20 of the PC.
What I'm trying to find out is that, is there a similar .bcs that I can use for areas like Umar Hills, Windspear Hills, etc ? Currently AmnTrp01.bcs, bodhitrp.bcs and Vamptrap.bcs (I think that's how its spelt) all seem to work only for areas within the city.
