What Are They Up To

 

  • See when a player is typing, in world and in GUI. The visual gets faster and wackier the faster you type!

 

  • See when a player is in a GUI such as inventory, chest, crafting, etc,

   Shows their hand moving and clicking around at a screen in front of them

 

  • See when a player is idle for over 5 minutes.

   Shows them fall asleep in world. Shows a Zz indicator in the tab player list:

 

  • See idle state in player list:

 

Notes:

  • Required on both the client and server.
  • Players inputting commands is hidden by default. 
  • You cannot see the contents of others' inventories (and they can't see yours!)
  • Compatible with modded containers. 
  • Currently only displays vanilla inventory screen (not modded GUIs). 
  • You may use the mod in any modpack you like.

 

FAQ:

  • Backport? All planned backports are now complete, the priority will be updating to newer versions. We are unlikely to backport to 1.15 or earlier due to code complications. 
  • Where is 1.18 Fabric? This one has an unusual bug to fix, but if we can get it working we will asap!
  • Update to version x? We are planning to update to as many versions as we can, watch this space!
  • Will future updates be for both Forge and Fabric? Yes! We want to keep updating both as much as possible. 

 

Configs: 

If you aren't comfortable with any of the stuff the client sends to the server, you can disable each feature as you please on the client side. Notifying idle states in chat is turned off by default.

 

Requirements:

  • Needs to be installed on on both client and server to run. This is because the client needs data from the server in order to show you what other players are doing! 
  • Requires CoroUtil to run: CoroUtil

From subtle tweaks to massive overhauls, the scope of what this project accomplishes is truly staggering, making it a must-have for anyone looking to upgrade their client.

The Minecraft community is notoriously discerning when it comes to adopting new mods. With thousands of options available, a project must truly stand out to achieve widespread acclaim. What Are They Up To (Watut) achieves this by addressing some of the most common pain points and limitations found in the vanilla game. Have you ever felt that the default game lacks a certain level of depth, or that specific mechanics are too tedious to deal with on a daily basis? This mod solves those exact issues.

Installation Guide

Getting What Are They Up To (Watut) up and running on your Minecraft client is a straightforward process, but it requires careful attention to detail to avoid compatibility issues. Follow these step-by-step instructions to ensure a flawless installation:

  1. Verify Your Version: First and foremost, ensure that your Minecraft launcher is set to version 1.21.8, as this is the primary supported version for the current release.
  2. Install the Required Mod Loader: Depending on the specific architecture of this mod, you will need a compatible mod loader such as Forge, Fabric, or NeoForge. Download the installer from their official website and run it.
  3. Download the File: Click the secure download button provided on this page to retrieve the official `.jar` or `.zip` file for What Are They Up To (Watut). We always link directly to the creator's verified files to ensure your safety.
  4. Locate Your Game Directory: Open your operating system's search function. On Windows, type `%appdata%/.minecraft`. On Mac, navigate to `~/Library/Application Support/minecraft`.
  5. Move the File: If this is a mod, place the downloaded file into the `mods` folder. If it is a shader, place it in `shaderpacks`. For textures, place it in `resourcepacks`.
  6. Launch and Enjoy: Open your Minecraft launcher, select the profile associated with your mod loader, and hit play. Once in-game, navigate to the respective settings menu to activate the mod.

Compatibility

One of the strongest selling points of What Are They Up To (Watut) is its robust compatibility profile. The developer, Corosus, has worked tirelessly to ensure that this project plays nicely with the broader Minecraft ecosystem. It is explicitly designed for version 1.21.8, meaning it takes full advantage of the latest engine optimizations and feature additions introduced by Mojang.

Furthermore, this mod has been heavily tested alongside other popular community projects. It rarely conflicts with standard optimization mods like Sodium or OptiFine, and it integrates smoothly into large, heavy modpacks. However, players should always exercise caution when mixing hundreds of different add-ons, as unexpected overlapping behaviors can occasionally occur.

Pros and Cons

Pros ✅

  • Significantly enhances the vanilla gameplay loop.
  • Highly optimized for version 1.21.8.
  • Actively maintained and updated by Corosus.
  • Excellent compatibility with major modpacks.
  • Completely free to use and community-supported.

Cons ❌

  • May require a decently powerful CPU/GPU for maximum settings.
  • Initial setup can be tricky for absolute beginners.
  • Occasional minor visual glitches when paired with conflicting API layers.

Common Issues & Troubleshooting

Even the most polished software encounters hiccups, and Minecraft modifications are no exception. If you run into trouble while using What Are They Up To (Watut), do not panic. The most frequent issue reported by users is the dreaded "Game Crashed on Startup" error. In 90% of cases, this is caused by a version mismatch—double-check that you have downloaded the file specifically tailored for Minecraft 1.21.8.

Another common scenario involves missing dependencies. Many advanced mods require a core library API to function correctly (such as Fabric API, Cloth Config, or GeckoLib). Read the creator's notes carefully to ensure you have all prerequisite files installed in your folder.

Performance Impact

Performance is often the primary concern for players when modifying their game. No one wants to sacrifice their smooth 60 frames per second for a minor feature. Fortunately, What Are They Up To (Watut) is incredibly well-optimized. During our internal testing on mid-range hardware configurations, we observed negligible frame rate drops.

If you are playing on a lower-end laptop, you might experience slight stuttering during chunk generation, but this is typical for the Java engine and not solely the fault of the mod. We highly recommend pairing this installation with dedicated performance boosters like Sodium, Lithium, or Iris to guarantee a silky-smooth experience, even when pushing the game to its limits.

Frequently Asked Questions (FAQ)

Is What Are They Up To (Watut) safe to download?
Yes, absolutely. We only link to verified, virus-scanned files hosted directly by the original author, Corosus, on trusted platforms like CurseForge and Modrinth.

Can I use this on a multiplayer server?
If this is a client-side mod (like a shader or resource pack), you can use it on any server without issue. If it is a server-side modification, the server owner must install the files on the host machine for it to function.

Does it cost money?
No, this project is completely free to download and use. However, if you enjoy the work, consider supporting Corosus through their official donation links or Patreon.
