Chunker

Pre-generate chunks ahead of time to reduce chunk generation overhead while players are roaming the world

Features

Control exact chunk-per-second pre-generation rates for great granularity over load impact while pre-genning.
Pause chunk generation tasks if required
Skip already generated chunks
Get detailed chunk pre-generation stats including processed chunks, skipped chunks and generation percentage.
Configurable optional persistent world border to keep players inside your generated chunk radius

Commands

There are permission nodes for pretty much everything, but you can grant a group/player full access by granting chunker.* a full list of available permission nodes is below:

Selection commands

/chunker world - List all worlds available for chunk pre-generation
/chunker world <worldName> - Select a world to control pre-generation for
/chunker center <x> <z> - Set the center of the pre-generation selection to the specified coordinates
/chunker center spawn - Set the center of the pre-generation selection to the world's spawnpoint
/chunker radius <blocks> - Set the radius of the selection, e.g 100 is 100 blocks in each direction from the center
/chunker corners <x1> <z1> <x2> <z2> - Set the corners of the selection to specific coordinates

Border commands

/chunker border - Toggle the world border on/off in the selected world

Lifecycle commands

/chunker start - Start generating chunks in the specified world
/chunker stop - Pause generation of chunks in the specified world
/chunker resume - Resume generation of chunks in the specified world
/chunker cancel - Cancel generation of chunks in the specified world

Pregen tuning

/chunker rate <chunksPerSecond> - Set the generation rate for chunks (default: 200)

Utility commands

/chunker trim - (DESTRUCTIVE) deletes chunks outside of the specified region, requires confirmation
/chunker reload - Reload the plugin
/chunker silent - Disables chat progress update output
/chunker quiet <seconds> - Change the progress update output frequency for both chat and console

Usage & examples

Generate chunks in a 5000 block radius in the world "default" centered on the spawnpoint

/chunker world default
/chunker center spawn
/chunker radius 5000
/chunker start
/chunker progress

Generate chunks in a 10000 block radius slowly to prevent impact in world "custom" centered on specific coordinates

/chunker world custom
/chunker center 123 321
/chunker radius 10000
/chunker rate 20 # 20 Chunks per second, 10% of the default
/chunker start
/chunker progress

Generate chunks between two sets of coordinates aggressively (requires a lot of resources), in a 20k block radius centered around spawn

/chunker world default
/chunker center spawn
/chunker radius 20000
/chunker rate 400 # double the 200 chunk per second default
/chunker start
/chunker progress

Create a world border 5000 blocks from spawn without pregeneration

/chunker world default
/chunker center spawn
/chunker radius 5000
/chunker border

Pregenerate chunks within 15000 blocks of spawn with a world border at 150 chunks per second, and trim chunks outside of the border

/chunker world default
/chunker center spawn
/chunker radius 15000
/chunker border
/chunker rate 150
/chunker start
/chunker trim --confirm
