I have two NPCs who are meant to attack each other on sight. They're set with 100 Aggression, 0 Personality, opposing factions that Love themselves and Hate each other. But they just stand there... If the Player moves into their field of detection, they attack just fine-- and will sometimes turn on each other if the Player leaves, but this really is not convenient since the Player is not meant to be able to get that close to them, or fight them... If anyone has any ideas, I'd be grateful.

Avoid have PlayerFaction on both of them.
Better dont have them both being members of same faction
Put their faction -100 reaction to enemyfaction

I suppose you dont want using scripts here...?

That's really quite odd... Check each of these things are correct:

-Each character is in a separate faction, and each faction has a disposition modifier of -100 to the other.
-Make sure there aren't any AI packages running on the NPCs that have the 'defensive combat' box checked (I'm not sure if this would actually affect it, but I have occasionally have NPCs refuse to fight because this was checked).
-Both NPCs have a confidence of 100
-Both NPCs have a responsibility of 0 (This is probably the one)
-Both NPCs aren't engaged in a wander package that has the 'Must Complete' box checked (Again, this is unlikely to affect it, I'm just covering all my bases).
-I'm not sure if it has an affect on fighting, but bump both the characters' energy level up to 100. If you're only using these specific references for this part of your quest it wont be a problem later.

Hope those help :foodndrink:

Dey,
I'd prefer to avoid scripts, since eventually there will be random possible NPCs

Tried with no AI packages at all and hit the same issue

I *bleieve* it is done, but will check

Shouldn't be, but I'll check

As you can see, I already have all the logical basis covered, so it's really odd why they will not fight... I have found if they are RIGHT ON TOP of each other, they initiate, but not anywhere before...

Now that does sound familiar... I once had two NPCs locked in a UseItemAt package, and wouldn't stop to continue with their other scripts. Oddly enough, the way to fix them was to put them right in front of each other. I never did work out what that was about.

One other thing that popped into my mind last night was that maybe you accidentally left a script on the base models (Presuming you're lazy like me and just copy existing NPCs for every new one you make), which forces them to stand still. I'm clutching at straws now though.

It's a long shot, but it may be a pathing issue (ie. the NPCs don't know how to get to each other), but that's unlikely. Still, just toss some path nodes in between the two guys.

If those don't work, my suggestion would be to simply remake the NPCs from scratch. I assume you're only using them for this part, of course. If not, and you've got a whole quest lined up on them, we'll have to actually work out what this problem is... <_<

Fortunately, it is just fighting-- nothing overly fancy, but it is necessary to the Mod idea that they actually fight each other

When I'm back at my Modding PC, I'll have another look at them
