Chunky

Chunky Plugin: Pre-Generating Your Minecraft Server World

Chunky is a powerful Bukkit plugin (and mod) designed to pre-generate chunks on your Minecraft server. Pre-generating your server’s world can significantly reduce CPU usage over time, ensuring smoother gameplay, optimized performance, and fewer lag spikes.

This guide explains how to install and use Chunky to prepare your server for peak performance.

Installation

For Bukkit-Based Servers

Download the Plugin: Get the latest .jar file from SpigotMC.
Install the Plugin: Place the downloaded .jar file into your server’s plugins folder. You can do this via your file manager or SFTP.
Restart the Server: Start your server to activate Chunky.

For Forge or Fabric-Based Servers

Download the Mod: Obtain the mod file from CurseForge or Modrinth.
Install the Mod: Place the downloaded .jar file into the /mods folder using your file manager or SFTP.
Restart the Server: Once restarted, Chunky will be ready to use.

Usage

Important: Pre-generating your world can significantly increase its size, so ensure your server has enough disk space. Use tools like onlinemo.de/world to estimate the size of your world before proceeding. Always back up your server before starting pre-generation.

Chunky offers several commands to control world pre-generation. Here are the key commands you’ll need:

/chunky radius <chunk-size> Defines the radius (in chunks) to be pre-generated, measured from the center. Example: 5000 means 5000 blocks in all directions.
/chunky center <x> <z> Sets the center point for pre-generation. By default, this is (0, 0).
/chunky setcorners <x1> <z1> <x2> <z2> Defines rectangular corners for a custom pre-generation area.
/chunky start Starts the pre-generation process.
/chunky pause Temporarily pauses the process.
/chunky resume Resumes a paused generation process.
/chunky stop Stops the pre-generation process entirely.
/chunky status Displays the progress and status of the current pre-generation.

For additional commands and tips, refer to Chunky’s documentation.

Example: Pre-Generating a 5000x5000 Area

To pre-generate a 5000x5000 block area centered at (0, 0), follow these steps:

Set the radius:
```
/chunky radius 5000
```
Set the center (optional, default is (0, 0)):
```
/chunky center 0 0
```
Start the pre-generation process:
```
/chunky start
```

Tips for Efficient Pre-Generation

Be Mindful of the Radius: Large radii can take hours to complete. Start with a reasonable size based on your server’s needs.
Run It During Off-Hours: Pre-generating chunks consumes server resources and may cause lag. Run it overnight or during downtime for minimal disruption.
Check the Status: Use /chunky status to monitor progress.

What Happens After Pre-Generation?

Once Chunky finishes, the specified area (e.g., from X 5000, Z 5000 to X -5000, Z -5000) will be fully generated and ready for players. This ensures smoother gameplay as players explore pre-generated chunks instead of forcing the server to generate them on the fly.

With Chunky, you’ll enhance your server’s performance and provide a seamless experience for your players!
