Chunky Commands Guide: Pre-Generate Your Minecraft World & Fix Common Issues

Experiencing server lag when players explore new areas? Pre-generating your Minecraft world can significantly improve performance by loading chunks beforehand. This guide will walk you through installing and using the Chunky mod (for Forge/Fabric/NeoForge) or the Chunky plugin (for Paper/Spigot/Purpur) on your MintServers Minecraft host to pre-generate your world efficiently.

What is Chunky?

Chunky is a popular tool designed specifically for pre-generating Minecraft world chunks. By generating terrain before players explore, you reduce the massive server load that occurs when new chunks are created on-the-fly. This leads to a much smoother gameplay experience with less lag, especially during initial exploration or when flying with an Elytra.

Choosing Between Chunky Mod and Plugin

• Chunky Plugin: Use this if your server runs Paper, Spigot, Purpur, or other Bukkit-based server software. Installation is typically simpler.
• Chunky Mod: Use this if your server runs Forge, Fabric, or NeoForge modded platforms.

You can easily install the correct version directly from your MintServers game panel.

Installing Chunky via MintServers Panel

Whether you need the mod or the plugin, the installation process via the MintServers panel is incredibly straightforward:

1. Log into your MintServers game panel.
2. Stop your server before making changes.
3. Navigate to the appropriate installer tab on the left sidebar. For Paper/Spigot/Purpur, click on Plugins. For Forge/Fabric/NeoForge, click on Mods.

4. In the search bar, type Chunky.

5. Find the main Chunky entry and verify it is the correct one (usually authored by llopis).
6. Select the version compatible with your Minecraft server version and server software.
7. Click the Install button.
8. Once installation is complete, start your server. Chunky will now be active!

Chunky Commands & Workflow

Chunky is controlled entirely via commands. You can run these commands directly in your MintServers game panel console, or in-game if you are an operator (OP).

Here is the basic workflow to get your generation started:

1. Select the World: Specify which world you want to pre-generate (e.g., overworld, nether, end). Use the command /chunky world world_nether.
2. Set the Shape and Center (Optional): By default, Chunky generates in a square shape around the world spawn. You can change the center by using /chunky center 100 -500.
3. Set the Radius: Define how far out from the center you want to generate chunks. For example, /chunky radius 5000 will prepare a 10,000 by 10,000 area.
4. Start the Task: Begin the pre-generation process by typing /chunky start.

/chunky help               (Displays available commands)
/chunky world [name]       (Selects the target world for generation)
/chunky shape [shape]      (Sets the shape, e.g., square or circle)
/chunky center [X Z]       (Sets the center point coordinates)
/chunky radius [blocks]    (Sets the radius or half-length to generate)
/chunky start              (Begins the pre-generation task)
/chunky pause              (Temporarily pauses the current task)
/chunky continue           (Resumes a paused task)
/chunky cancel             (Stops and cancels the current task)
/chunky progress           (Shows current completion percentage and ETA)

Recommended Generation Radiuses

Larger radiuses require more disk space and generation time. It is usually best to start small and expand if your players start reaching the borders!

Monitoring Your Progress

Use the /chunky progress command periodically in the console or in-game to check how the generation is going. You will see the percentage completed, the number of chunks processed, and an estimated time remaining. Keep in mind the ETA can fluctuate based on server load and the complexity of the terrain being generated.

Generating large areas can take a significant amount of time, potentially hours or even days for very large radiuses. Because pre-generating chunks is resource-intensive, your server's performance might decrease while Chunky is running. It is highly recommended to run these tasks during off-peak hours when fewer players are online.

Whether you are using the Chunky plugin on Paper/Spigot or the Chunky mod on Forge/Fabric, this process will ensure your players have a buttery-smooth experience exploring your world.
