Appendix A: Hide Others Tampermonkey

To clean up the game and make KringleCon a bit less crowded and make it easier to find things in the game, I used JavaScript to remove the other players from the map.

In the Inspector window, I see the players are each a div with classes ent and player:


I’ll also notice that I have the class me.

I can add a style visibility: hidden to one of those divisions, and the player disappears. I’ll use that to create a loop that runs each second, find each player that isn’t me, and sets them to hidden.

As a TamperMonkey script, here’s the source:

// ==UserScript==
// @name         Hide Others
// @namespace
// @version      0.1
// @description  Hide other players in KingleCon
// @author       0xdf
// @match
// @grant        none
// ==/UserScript==

window.setInterval(hideplayers, 1000);
function hideplayers(){
  document.querySelectorAll('.player').forEach(function (player) {
    if (!player.className.includes("me")) { = 'hidden';
