I've tried to stop a creature fighting back after being hit by the player but it doesn't work so far.

I've added a faction which has the player faction set to 100 disposition.

I've set aggression to 0 and responsibility to 100.

But still it fights back.

How come the player can hit player owned horses and not get attacked?

There's a "set ignorefriendlyhits" option.

There's also the option of using "stopcombat" if the creature's target is the player.

Thanks, but how do I set ignorefriendlyhits to work?

The Wiki says

(nothing) setignorefriendlyhits willignore:bool 

Which doesn't mean a lot to me.

I currently am getting around it with using Begin OnHit and StopCombat, but the problem with that is that the music jumps as if it was about to play the battle music, which is kind of annoying.

You can set the creature to be owned by the player, which will cause it to ignore all attacks from the player regardless of anything else. This works for NPCs too.

But thats only for the ref when hand placed right? I can't do that to the creature in the Creatures list.

That I don't know. Figured I'd throw one more possibility out there in case it would be helpful.

Will this is a simple idea, and I'm not sure if it would work, but its worth a try:

Scn HorseNoAttack [or whatever your script's called]Begin OnHitStopcombatend

but tbh that's just a random idea, so you might need to build on it a bit, but may as well give it a try, it should just stopcombat with the player every time the horse is hit, which should work.

Yeah that's what I'm already doing, but it is not perfect. The problem is now the music stops as if the battle music is about to run, then the next track starts, which is kind of annoying and breaks the immersion.
