Hello guys, I'm trying to implement a mod that makes a npc respond to the player with a custom message per player. I've tried searching the forum and other sources, but didn't find any answer (Maybe i'm missing something please let me know). I'm a programer that so the coding part isn't the issue, i'm currently struggling to get some documentation how this could work. If you have any sources i can read through i would be really thankful.
