Update NPC Actors to work with WBHarry/pf2e-bestiary-tracking's NPC Tracker

update-npc-actors.js

// Change this to whatever makes sense for your layout.
// For me, I have only a top-level of folders that I put all of the current NPCs into, so a simple single-level traversal works great.

let npcFolders = 
   game.actors.apps[0].folders.filter(f => f.name === "Classmates" || f.name === "Faculty");

// dig into the folders chosen and make a single array of all actors in them
let npcs = 
   npcFolders.flatMap(f => f.contents);

function addNpcTrait(npc) {
  if (npc.traits.has("npc")) {
    return;
  }
  npc.system.traits.value.push("npc");
}

function setUnique(npc) {
 if (npc.rarity === "unique") {
    return;
 }
 npc.system.traits.rarity = "unique";
}

// apply modifications to each actor
npcs.forEach(n => {
 addNpcTrait(n);
 setUnique(n);
});
