Like the final Conjuration Quest of winterhold college. You summon an actor that attacks anyone. I post the code I wrote:

Scriptname HostileSummon extends ActorEvent OnLoad()  self.SetRelationshipRank(Game.GetPlayer(), -4)  Game.GetPlayer().SetRelationshipRank(self, -4)  self.SetAv("Aggression", 1)  self.StartCombat(Game.GetPlayer())endEvent

But doesn't work.. suggestions?

Does it run? Have you tried a trace or debug?

Yes, Debug.MessageBox("jesus"), when I use the spell the box appears, but nothing else happens.

Does OnLoad work with the Actors ?

Try maybe with a OnLocationChange event. It would work if the summoning is considered by the game as a location change.

Or if you set up a default package for the summoned creature, try a On PackageStart event, when you summon it, it will start using its package and the event may load this way.

This isn't the problem, I tried Debug.MessageBox(self) and the correct name of the actor appears. Damn

I think the problem may be your script runs before the summoned creatures relationship to the player is set by the summon entry point trying on package start may help or try utility.wait (2) at the start of your unload event script.

Mmm.. now I try, but I used Debug.MessageBox() to test every variable and the changes are valid..

It doesn't work ;(

Its possible you can't make a summon hostile to its summoner. The quest you are talking about may use a script to move the creature in rather than the summon effect. Of course you could do something similar.

Just speculation, I haven't done much with relationships so I can't validate you script is correct.

possiblitiy 1)
Try to remove the summoned creature from all factions. This is different from relationships. Without a faction, it has no allies.
possibility 2)
Try to pin the Frenzy spell effect on the creature after it is summoned.

I got killed by my own Storm Atronoch yesterday...it just attacked me out of the blue...we weren't even fighting anything. I had dropped a bunch of loot about 30 seconds earlier, maybe something bounced at it and upset it? but that doesn't explain why it waited before kiiling me.

1) Already tried.
2) I'm going to prove it tomorrow
Thanks to everyone for help I will let you know!
