GlymeraChunkLoader - Keep Chunks Alive!

Permanently keep chunks loaded and ticking without any player nearby. Survives server restarts.

What is GlymeraChunkLoader?

GlymeraChunkLoader lets server operators force-load specific chunks so they remain active even when no player is present. Loaded chunks keep ticking — crops grow, redstone fires, entities move, everything behaves as if a player is standing right there.

All configured chunks persist across server restarts via a simple JSON config that can also be edited by hand.

Commands

All commands are OP-only.

Load & Unload

/cl load [radius]  - Force-load the chunk you're standing in (radius 0-16, default 0)
/cl unload         - Release the chunk you're standing in

Radius example: /cl load 3 force-loads a 7x7 area (49 chunks) centered on your position.

Management

/cl list           - List all force-loaded chunks (grouped by world)
/cl status         - Verify which chunks are actually loaded and ticking right now
/cl reload         - Reload config from disk after manual edits

Tick-Test Clock

/cl test           - Mark a nearby chest as a tick-test clock
/cl test off       - Stop the tick-test

Stand next to a chest and run /cl test. The plugin will add 1 Rock_Stone every 60 real seconds to the chest. Walk away, come back later, count the stones — that's how many minutes the chunk was actively ticking in your absence.

Chest full? Pauses automatically, resumes when space is freed.
Chest destroyed? Test stops automatically.

Config

Located at plugins/GlymeraChunkLoader/config.json. Can be edited manually — use /cl reload to apply changes.

{
  "chunks": [
    {
      "world": "default",
      "x": -56,
      "z": 47
    },
    {
      "world": "plains_1",
      "x": 10,
      "z": -3
    }
  ]
}

Each entry specifies the world name and chunk coordinates (not block coordinates). Chunks from different worlds are fully supported.

How It Works

Uses Hytale's native WorldChunk.addKeepLoaded() API (ref-counted, prevents unloading)
A maintenance task runs every 5 seconds to ensure all configured chunks stay loaded and ticking
Sets the TICKING flag and resets keepAlive / activeTimer to prevent the unload system from evicting chunks
Chunks are loaded asynchronously via getChunkReferenceAsync() on first activation
All chunk operations run on the world thread for thread safety
No fake players, no network overhead — minimal performance impact

Installation
