I am trying to recreate an event similar to the undead dragon encounter in Labrynthian. I added all the parts that I could find but for some reason when I preview it in-game there is just an empty mound.
someone please help!

I would examine the quest, check for aliases for the undead dragon and see what it's doing with it.

uhhh what? all I can find is a Quest alias list that I can't do anything with under the character tab
so far I have made a copy of the undead dragon,
I copy/paste the dragon-mound parts from the warehouse-prefab,
then Linked Ref the dragon-mound to the undead dragon
that's all I can figure out at the moment
I would like to have the dragon burst out of the mound after pulling a lever

Well after about 10 seconds of looking, I saw this in stage 20 of the quest:


alias_SkeletalDragon.getActorReference().startCombat(game.getPlayer())

So put this script on the dragon, and set the lever as it's activate parent.

OnActivate(ObjectReference What)	 StartCombat(Game.GetPlayer())EndEvent.

(Edit) If you want the dragon to be lootable, however, do it in the quest alias panel, and make a few tweaks;

ReferenceAlias Property Attacker Auto ; Set this to the quest alias reference of the dragonOnActivate(ObjectReference What)	 StartCombat(Game.GetPlayer())	 Attacker.Clear() ; Clears the dragon quest alias, detaching this script from the dragon so it can be looted after it's dead.EndEvent.

thanks for your assistance!
...sorry I'm new to this

Ok I got him in and able to come out at me to attack, however you should probably know more to begin with...
I am trying to make it where "wandering adventurer" NPCs will come in, then I pull the lever to release the dragon and he will then fight/kill them.
so how would i need to change the script so that he comes out to attack others and not me?
p.s. I made him an ally so now he just doesn't come out at all
