You'd likely need to know the existing personality tags of the specific NPC if you want to add on to their personalities.
If you tell me which NPC I can give you their personality tags.
Hrm. If we are attempting to replicate a npc and only adjust a few things, then by this logic we'll need all their bells and whistles for information, yes? But the NPC at the very least keeps their home, general pathing and whatnot?
For example, if we tweak the vendors, do they still retain their stock and sales?
Semi related, could this be used so you don't get eaten in the wild by a certain NPC, or has that been fixed?
I haven't tried altering any NPCs yet, but I presume if you leave the physical and private description fields blank for the original NPCs, then they will default to the original description for that NPC.
Of course this is all new stuff, so I could be wrong, but that is the impression I am given if NPC descriptions are to be kept hidden.
You can only change the original NPCs into ones of the same gender.
However as far as I've figured, you can make it so the AI treats the character as the gender that you want by adding that detail in different ways, such as in the Public/Private Character Description, and in the character's Set Knowledge.
I don't know how far you have to go exactly, and the more stuff you change from the original NPC's original settings the more different they will become from their usual self.
Hang on let me check if the information is still floating around in the 1.7.0 level0 file. I technically revealed this before, but I didn't know it was for Darian at the time. If it's been hidden since, I'm not going to reveal it, otherwise, might as well.
Also, you can find this out if you spend any significant length of time with him. I even saw signs of it before I put the two things together.
Right, so that information isn't uncompressed anymore, so you won't see it in the files, which means I probably shouldn't share it, since it's not publicly available knowledge. I suspect it's set knowledge, so if you mod Darian it will still be a hidden part of his personality because anything new is appended to the existing knowledge pool.
