GCleanroomGenerator is a Bukkit plugin that generates cleanroom-style flat worlds, by implementing a configurable flat chunk generator. It can be configured and used by plugins such as Multiverse, or bukkit.yml.

Changes

Generated chunks are all forced to be PLAINS biome
Tested to work fully in Spigot and PaperSpigot 1.9, 1.10 and 1.11

Usage

Configuration string

A CleanroomGenerator config string is 'CleanroomGenerator:' followed by a comma-separated list of materials and their heights. These are heights from Y0 upwards, then the rest is generated is AIR.

By default, CleanroomGenerator also generates a layer of bedrock at Y0, but this can be skipped by beginning the configuration string with a ..

For example:

CleanroomGenerator:62,dirt,1,grass means:
- At Y 0, generate 1 layer of bedrock, then. . .
- From Y 1 to Y 63 (or 62 layers), generate dirt, then. . .
- From Y 64 to Y 64 (or 1 layer), generate grass
CleanroomGenerator:.10,1:5,20,3:1,1,grass means:
- From Y 0 to Y 10 (or 10 layers), generate andesite (1:5), then. . .
- From Y 11 to Y 30 (or 20 layers), generate coarse dirt (3:1), then. . .
- From Y 31 to Y 31 (or 1 layer), generate grass
CleanroomGenerator:. means:
- Generate a void world, excluding even a bedrock layer at Y0

`bukkit.yml`

Bukkit can be configured to choose a generator per-world. See http://wiki.bukkit.org/Bukkit.yml#.2AOPTIONAL.2A_worlds

Multiverse

To make a Multiverse world use CleanroomGenerator:

/mvm set generator <config> <world name>
/mv unload <world name>
/mv load <world name>

Where:

<config> is the configuration string (e.g. CleanroomGenerator:62,dirt,1,grass)
<world name> is the name of the world (e.g. world_nether)
