About Chunky

🔌 About Chunky

Chunky is a Minecraft plugin that pre-generates (pre-gens) chunks on a server so terrain and world data exist before players explore an area. It runs generation tasks in the background, reports progress, and can be paused and resumed. Chunky is intended for server administrators who want to avoid generation lag when players explore new areas.

🎯 Purpose

Chunky's core purpose is to remove or reduce in-game lag caused by on-demand chunk generation by creating chunk data ahead of player exploration. It is designed for server setup and maintenance workflows where administrators want predictable performance and prepared areas.

⚙️ Features

  • Start one or multiple chunk generation tasks simultaneously.
  • Pause and resume saved generation tasks.
  • Detailed task reporting (chunks processed, percent complete, ETA, chunks/sec).
  • Multiple selection shapes (circle, square, custom shapes) for controlled generation.
  • World-border integration via an optional ChunkyBorder add-on.
  • Commands to inspect and control selection, center, radius, and generation pattern.
  • Ability to trim (delete) chunks outside the current selection.

🧩 Who It Is For

  • Server owners and administrators running survival, SMP, or public servers who want to pregenerate terrain.
  • Operators preparing large maps before opening to players.
  • Hosts that need predictable world-generation behavior to reduce runtime spikes.

🏗️ Example Use Cases

  • Pre-generate a spawn area and surrounding map to prevent generation lag during launch.
  • Generate the Nether or End to a set radius around spawn before inviting players.
  • Use multiple tasks to generate different worlds or regions in parallel and pause/resume overnight.

⚙️ Installation

📥 Setup

  • Download the official plugin .jar from the plugin's distribution page.
  • Place the .jar into your server's plugins/ directory for a Spigot-compatible server.
  • Restart the server and check the console to confirm Chunky loaded correctly.

📦 Dependencies

  • ChunkyBorder (optional): an add-on that provides world-border based selection support.

🧠 Technical Notes

  • Chunky is distributed with builds targeting multiple Minecraft versions; the plugin author provides recommended downloads for specific MC version ranges.
  • Chunky exposes multiple concurrent generation tasks to leverage CPU resources; administrators should monitor server CPU/memory when running large jobs.
  • The plugin includes a progress/reporting system and ability to save/restore paused tasks.

🤝 When This Plugin Is Useful

If you need to prepare large map areas before players explore them, Chunky is useful because it creates chunk data ahead of time, reducing runtime generation load and helping provide a more consistent performance profile for your server.
