That's probably how it works, too. I've messed with a few others (unused values) you mentioned in your t-script reference as well. CreatureSleep, CreatureWake behave just as you'd expect them to. Can be used as expressions, thus setting a trigger off.
group TrigRaptorisAsleep = {
int ext_GeometryType = 1
string Class = "CCreatureTrigger"
bool CreatureSleep = true
int FireCount = 1
int ActionType = 0
string A00 = "RaptorB300-00"
string Sample = "VA32"
}
*Rather funny, if you bring Anne back to life, she crawls around on the ground! lol (teleporting straightens her up though)
