[Greasemonkey] On/Off CG player button (avoid high CPU consumption)

Apps & tools
#1

CodinGame player (canvas) on Firefox consume lot of CPU (especially on Spoon puzzle) which is annoying and most of the time we don’t need it.

I made a Greasemonkey script which add a toggle On/Off button to hide CodinGame player and let our CPU breathe.

Script :

    // ==UserScript==
    // @name        Codingame On/Off Player
    // @namespace   http://www.codingame.com
    // @version     1
    // @include     http://www.codingame.com/*
    // @require     http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
    // @require     https://gist.github.com/raw/2625891/waitForKeyElements.js
    // @grant       none
    // ==/UserScript==
    
    var iFrame = "#ideFrame";
    var btnText = "On/Off Player";
    var btnImg = "http://png-5.findicons.com/files/icons/2580/android_icons/24/nuclear_power_plant_checkmark.png";
    var headerBtnNode = null;
    
    this.$ = this.jQuery = jQuery.noConflict(true);
    
    // Wait for div "headerButtons" (Invite Friends, I need help, ...)
    waitForKeyElements("div.headerButtons", waitForHeaderBtn, false, iFrame);
    
    function waitForHeaderBtn(jNode) {
        headerBtnNode = jNode;
        waitForKeyElements(".player", addTogglePlayerBtn, false, iFrame);
    }
    
    function addTogglePlayerBtn(jNode) {
        if(headerBtnNode != null) {
            headerBtnNode.prepend("<div class=\"headerButtonInstance\"><button class=\"headerButton togglePlayer\"><div class=\"button_icon iconNormal icon inviteFriend\" style=\"margin-right:8px\"><img src=\"" + btnImg + "\"></div><span>" + btnText + "</span></button></div>");
        $(iFrame).contents().find(".togglePlayer").click(function() {
            jNode.toggle();
        });
    }
}

E.g: APU: Init Phase (hidden player)

/!\ You must have Greasemonkey/tampermonkey installed to use it.

Install : Codingame On/Off Player

Enjoy :wink:

Tested on chrome with tampermonkey, it works fine there too. :smiley:

Maybe it improves the CPU performances (I couldn’t test that yet), but the memory is still consumed (and in particular for the APU puzzles, it still leaks). Is that normal?

#3

Yes it’s normal because the player still exist. In some cases like in PA2 hide the player don’t decrease CPU usage (even if I remove it) and I don’t know why, I mean I do not know what causes it, so even if I remove the player instead of hide it, I don’t think it will help for RAM consumption.
In APU puzzles I don’t have memory leaks anymore (CG made an update on it).

#4

where should this button appear?
i just tried it and didn’t see the button …

maybe it is no longer compatible with the last UI update

#5

No, the script is searching for HTML elements that doesn’t exist.
