Faction information.

[Jojash]

Is there a way to check which factions an NPC is a member of and then store that information? Short of checking if they are a member of every single faction, I can't think of a way to do this, any help would be greatly appreciated!

Here's how I would go about doing that:

 

1. Make two form lists. Use one as a list of all factions to check for membership, and the other as a temporary list of factions that an NPC is a member of.

2. Get a handle to the NPC's reference in a script variable using whatever means you prefer. GetFirstRef/GetNextRef, GetCrosshairRef, GetSelf in an effect script on a weapon, etc.

3. Check each faction for membership by iterating through the master faction list like so:

 

set iCount to 0
label 10
if(iCount != listgetcount FactionList)
    set rFaction to ListGetNthForm FactionList iCount
    if(rActor.GetInFaction rFaction)
        ListAddForm NPCFactions rFaction
    endif
    set iCount to iCount + 1
    goto 10
endif

This gives you a form list (NPCFactions) that contains all factions from FactionList that the NPC is a member of. You can do whatever you like with that information at this point. If you are doing this for multiple NPCs, you will need to empty the NPCFactions list each time you switch to a new one:

 

label 20
if(ListGetCount NPCFactions)
    ListRemoveNthForm NPCFactions 0
    goto 20
endif

 

Note that the additions to NPCFactions will not persist through saving and loading. If you need to make a permanent copy of the list that persists, you can do that like so:

 

label 30
if(iCount != ListGetCount NPCFactions)
    set rFaction to ListGetNthForm NPCFactions iCount
    AddFormToFormList PermFactionList rFaction
    set iCount to iCount + 1
    goto 30
endif

Thank you so much! That's really, really helpful! :D
