Paint Biome Region

Paints a biome over a whole region and writes it to the world. Everyone sees it, and it survives a restart.

Fields

Field	Type	Description
biome	Var<String>	Biome key to paint
region	WORLDEDIT_SELECTION / RADIUS_AROUND_PLAYER	Where the region comes from
radius	Var<Int>	Radius in blocks, used by the radius mode
snapshotId	String	Name to record the previous biomes under. Empty means no undo.

Snapshots

When snapshotId is set, the biomes already present are read and stored before anything is overwritten. Restore Biome puts them back under the same name.

Snapshots work for both region modes. A name is reused if it already exists, so painting twice under the same name keeps only the most recent "before" state — give each zone its own name if you want to undo them independently.

Performance

Biomes are stored per 4×4×4 cell, so the region is walked on that grid rather than block by block. Reading the previous biomes happens off the main thread, and writes are scheduled on the region that owns each chunk, which keeps large selections from stalling the server.

WorldEdit

WORLDEDIT_SELECTION uses the triggering player's current selection and requires WorldEdit or FAWE. Without a selection — or without the plugin — the action logs a warning and does nothing.

Example

Burn a zone, then restore it when the quest ends:

biome:      typewriter:ember_wastes
region:     WORLDEDIT_SELECTION
snapshotId: quete_incendie
