well i think i kno what u mean...
trigger action??
like say you have a weapon and u use it and if it is on a certain npc u want that npc to activate or something like that
NPC Code:
triggeraction x,y,triggeractionname,parameters;
NPC Code:
if (actiontriggeractionname)
i kno this might sound confusing cuz im not sure what exactly ur tryin to do
