Enhances MooMoo.io with mini-mods to level the playing field against cheaters whilst being fair to non-script users.
This user script combines a large bunch of mods into one big one, allowing for a bit more fun while playing the game. For fairness, it doesn't include things like auto-heal, instant-kill, or anything like that, which'd make things unfair for others, however instead, you get a ton of convenient utility tools. Due to the nature of this script it is compliant with FRVR's Terms of Service by focusing on convenience, not "hacks, cheats, and exploits".
How do I use the script?
It's simple! First, install the script by clicking on the green install button, right here:
If you already have Tampermonkey, click the 'install' button, if not... add the Tampermonkey chrome extension.
After that, actually using the script is easy! Just open moomoo.io and the script will be enabled.
Choose the settings you want to use, select your name, server, colour and enter the game!.
BTW, in the main menu, you should see the '.', in the MooMoo.io title screen text coloured beige. If it's white, the mod wasn't enabled, try reloading. If it's still not working. Feel free to for some help, response may be slow.Why does the mod not work?
This Utility mod is designed specifically to work with Google Chrome on Windows on a laptop... because that's exactly what I'm using to develop this script. This script may work with other browsers, the script may work on Mac, Linux, and other operating systems and it might even work on your phone, tablet, or even smart TV, but I can't guarantee it will because I can't test it.
Due to the way in which I code, as long as you're using a modern browser, you should be fine regardless regardless of what you're using. However, if anything happens contact me and let me know.What's the update schedule? / Can I contribute?
To be transparent, this was a side project to a side project, and I have no intention to actively update this script with major features until "later". Small updates and bug fixes will still come out here and there.
However, I highly encourage users to contribute to the project themselves. The GitHub repository is public, and I will be actively reading issues and reviewing Pull Requests to update the official script. As per the license, you are also free to fork the project and maintain your own version.

This script is developed and tested on a Windows laptop using Google Chrome with the Tampermonkey extension. It should work with other browsers, operating systems, and userscript managers (Greasemonkey), but they are not officially supported as they are completely untested.
It is unlikely this script will work well with other moomoo.io scripts. This script records a number of actions that occur in the game to function correctly. Other scripts may interfere with this in-game tracking and cause bugs. The use of cheats on top of this mod, is not condoned - anti-cheat may be added, if this becomes a major thing.Why is there no auto-heal or instant kill feature?
Good question, the short answer: it's annoying. I made the MooMoo.io Insane Mod! user script in 2017, and it was one of the first to include such features. In reality, it just makes the game much more... toxic? There was a time when if you didn't have a script with auto-heal you'd be killed after just three minutes of playing.
I don't know about you, but that's just not fun. I want to have a fair fight without using such OP features and that's why I made this one. It doesn't offer auto-heal or instant kill, but it offers enough useful features that one could say it helps level-the-playing field.Can I use parts of the code in my user script?
Sure! Use as much of this script as you want, I've actually tried to make the code somewhat easy to understand to allow people to do just that.
However, this script has a license. In short, for any public user script that uses some of my code, the user script should not include any auto-heal or instant-kill features, and the script must also state any changes made and use the same license as this one. I will be requesting takedowns of scripts that violate these terms.

... I'll be updating this FAQ with questions I get from the Feedback tab.
Settings Manager
Adds a new "Gameplay Settings" panel to the main menu. This UI allows you to enable, disable, and configure every mini-mod included in this script.Scrollable Inventory
This mini-mod allows you to scroll through your items on your hotbar using your mouse wheel, as opposed to using the 1-9 keys or clicking. It includes options for inverting scroll direction and smart-switching back to your last-used weapon after placing an item.Wearables Toolbar
Sometimes there are just not enough keys to bind to the hats and accessories you may use, so that's why I've designed & developed a hotbar specifically for the hats & accessories you currently own. It's a draggable UI panel that lets you pin your favorite wearables for one-click equipping.Typing Indicator
As you type in the chat box, this mini-mod sends a "..." loading animation to other players, letting them know you are writing a message.Proximity Chat
Adds a persistent chat log for nearby players, just like in basically any other game. It displays messages with timestamps and the player's name, including their leaderboard rank if applicable.
Here are some of the features planned for future updates:
