How can I get two NPCs to fight? Is a script needed? And also, how do I get an NPC to follow the player and attack anyone of X faction? Just need this information for a mod I'm making for personal use.

http://planetelderscrolls.gamespy.com/View.php?id=6083&view=Mods.Detail has the answers to your questions, and examples on how to use them in scripts.
http://planetelderscrolls.gamespy.com/View.php?view=utilities.detail&id=58 also has some scripts on making NPCs fight.

StartCombat "ID of Other Fighter"

Put that in a script and it should work fine n dandy ^_^


I'm not sure about the companion one though, but I would definatly take a look at grumpy scripts

I use that whenever I need someone to follow me in a quest, even if for 5 minutes.
