Hi!

I am just trying to make a npc and his friends turn hostile to the player at the end of a conversation.
I made it the same way than when the thalmor patrol could turn hostile if you question them too much, I created an hostile to the player faction and at the end of the dialogue I do a akSpeaker.AddToFaction(enemyfaction).

Problem is the npc attacks me but not his friends, they just stare at the fight...

I am obviously missing something, but what?

You might need to take a look at the others' AI data. Check what their aggressiveness is, whether or not they help allies/friends, etc. If nothing seems out of place, you could try using http://www.creationkit.com/SetEnemy_-_Faction instead.

Both (Thalmors characters and mine) are set to help friends and allies...thalmor is very aggressive and my faction (vigilants) is aggressive, I don't think that's the problem and I would like to avoid to modify vanilla factions for compatibility.
I don't really want to use Setenemy because I only want the nearby npcs to go hostile...it works for the thalmor, it should work here

If nothing works, then I guess you're just going to have to use StartCombat(Game.GetPlayer()) on all three of them.

But I don't necessarily know where there are or how many there are, except in their bastion...

Sorry, I thought you were using quest aliases like in WERoad03. Hmm... did you check to see whether or not your 3 actors are friends and allies? Maybe that's why they don't help each other. I really can't think of why else they wouldn't.

You say that you don't know where or how many there are. So just how exactly is this dialogue supposed to happen? Do you get this dialogue from every single actor in the bastion, and you want everyone in the same room as the current speaker to attack the player?

No, like in WEThalmorDialogue.

Well, there are all in the VigilantsOfStendarrFaction which is allied with itself, so they should all be allies. And if I directly attack one myself they are helping eachother.

In fact you can see the dialogue for yourself, I am trying to reactivate some unused dialogue of the vigilant and expand it a bit, look at the DialogueGenericVigilantsofStendarr quest, in the Dialogue view there is a part where vigilants try to take your daedric artifacts. I am just trying to make the speaker and nearby vigilants attack the player if you refuse.

Hmm... that is weird how they don't help each other until you attack one of them. I can't figure it out either.

Since you say they help each other if you attack them first, try using akSpeaker.SendAssaultAlarm().

Well, it seems to work perfectly, thanks a lot!

In fact this is an even better solution since I don't need to create a fake faction...it makes me wonder why the thalmor quest doesn't use the same method!

Well, send assault alarm makes the game think you just attacked the other person. So it's got side effects like guards trying to attack or arrest you if they happen to be there. The method with the factions is a lot cleaner.

Oh...well yes, it can be a problem...
So back to mess with factions...tried to put all the npcs into a frenzied agression level, added alliance between standard and fake vigilant factions (there are none with the thalmor ones) but still no luck

I wonder why I always end to pass hours to do the simpliest thing in the ck and it still doesn't work!
