here I had the same question:
http://www.frictionalgames.com/forum/thread-20463.html
example:
void latern(string &in asName, int alCount)
{
RemoveItem("lantern_1");
SetEntityActive("servant_grunt_1", true);
SetEnemyDisableTriggers("servant_grunt_1", true); //monster off
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_1", 0, "Idle");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_2", 0, "Idle");
}
you have to set path nodes for the monster!!!
but thats only the way to make the enemy not to attac you...
