how do I make a vampire npc that wears a vampire face, has the vampire blood but does not attack the player. the npc should defense himself, when attacked. how do I manage this? has someone a script for that or can i make it via ai?
It would be fairly simple if you could just give them a vampire head and give them a script that makes them a carrier or Porphyric Hemophilia, but not a full vampire, even though they would appear as such. I'm assuming he'd be alone, and if that's the case, that should work. I'm not nearly as witty with the CS as other people who I'm sure will reply to this thread, so they'll probably have something better.
Try to take an existing vampire, change his ID, set Fight in AI tab to 30 and save. CS will ask whether you want to change the existing one or create a new record; select the latter. You may need a custom version of the vampire script (Vampire_Aundae/Berne/Quarra) with edited out parts that SetFight in case that PC is not a vampire or a rival clan vampire.
The script is only for setting the NPC's fight and disposition and to also keep track of kills if the player is doing the vampire hunt quest(s). I just copy one of the vampires and set their fight to 30 if the NPC is not going to be a member of a particular vampire clan.
