Hmm you could just do something like this in the class script

//NPC.addMember(this); to call it
public function addMember(id) {
  this.moblist.add(id);
}

public function onCallMob() {
  for (temp.npc: this.moblist) temp.npc.trigger("YourTrigger", "");
}

public function onYourTrigger() {
  //Hell Yeah!
}
