About this Mod

Auto Chunky

A lightweight, server-side utility mod that automatically pauses world pre-generation when players are online and resumes when they leave.

Perfect for servers using the Chunky mod to pre-generate their worlds! You no longer have to worry about the server lagging when players join, or forgetting to resume Chunky when the server is empty.

How it works

  • Player Joins: The mod instantly pauses Chunky behind the scenes (/chunky pause).
  • Server Becomes Empty: The mod starts a 2-minute timer. If no one joins during this time, it automatically resumes generation (/chunky continue).

Commands

Requires OP / Permission level 2

  • /autochunky toggle - Turns the automation ON or OFF.
  • /autochunky status - Checks if the automation is currently running.

Requirements & Recommended Setup

  • Server-side only! Your players do NOT need to download this to join your server.
  • Fabric Loader: Version 0.18.5 or higher is strictly required.
  • Chunky must be installed on the server for this mod to have any effect.
  • Highly Recommended: Set continueOnRestart to true in your Chunky configuration! This ensures Chunky starts generating immediately when the server boots up, allowing Auto Chunky to perfectly manage pausing and resuming from the very beginning.

Permissions & Modpacks

You are totally free to use this mod in your modpacks! If you wish to copy, fork, or use the code in your own projects, you are welcome to do so, provided you give proper credit to the original author (Gabbe). Released under the MIT License.

Frequently Asked Questions

Auto Chunky server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Auto Chunky compatible with fabric?

Auto Chunky officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Auto Chunky – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Auto Chunky consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
