Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for NeoForge only.

⬇ Download for 1.21.4⬇ Download for 1.21.1
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Keep Your Minecraft Server Smooth! 🚀

This mod automatically cleans up entities on your Minecraft server to prevent lag. It does this at regular intervals that you can configure. You can also enable/disable and reset the timer with a command.

⚙️ How does it work?

The "Custom Clear Lag" mod works in the background on your server. Here are the key steps:

  1. 📝 Configuration: When the server starts for the first time with the mod installed, a configuration file named clear_lag.json is created in the config/oas_work/ folder.
  2. 📖 Reading the configuration file: The mod reads this clear_lag.json file to find out:
    • ⏱️ time: After how many minutes the cleanup should be performed (default is 5 minutes).
    • 💥 command: Which command should be executed for the cleanup (default is kill @e which kills all entities, be careful!).
  3. ⏳ Countdown: The mod counts the time elapsed in the game.
  4. 🧹 Automatic Cleanup: Once the configured time has elapsed, the mod executes the command defined in the configuration file. After the cleanup, the time counter is reset and starts again.

🎮 How to use it?

  1. **🛠️ Configuration (optional but **recommended):

    • 📂 Locate the configuration file: Go to the config/oas_work/ folder of your server and open the clear_lag.json file with a text editor.
    • ✏️ Modify the settings:
      • "time": 5, Change 5 to the desired number of minutes between each cleanup (e.g., 10 for 10 minutes).
      • "command": "kill @e" ⚠️ VERY IMPORTANT: The default command kill @e kills ALL entities (items on the ground, animals, players…). You MUST change it to a more targeted cleanup command. For example:
        • "/kill @e[type=!minecraft:player,distance=500]" (Kills all entities except players, more than 500 blocks away - adapt to your server).
        • /minecraft:kill @e[type=!player,tag=!keep] (Requires tags to protect certain entities, more advanced).
    • 💾 Save the clear_lag.json file. 🔄 Changes are applied immediately, no server restart needed!
  2. 🕹️ In-game commands (for server operators):

    Open the server console or the in-game chat (if you are an operator) and use the command: /cclearlag

    • /cclearlag stop <true/false> :

      • /cclearlag stop true 🛑 Stops automatic cleanup.
      • /cclearlag stop false ✅ Reactivates automatic cleanup.
    • /cclearlag reset <true/false> or /cclearlag reset :

      • 🔄 Resets the timer. The countdown to the next cleanup will restart from zero. The true/false argument has no effect here, only reset matters.
