Bonemeal Tweaker

This modification completely changes how bone meal works in Minecraft, giving players full control over which plants appear when using it.

Configuration via config files

All parameters are configured through JSON files in the config/bonemealtweaker folder. Each block has its own configuration file. Here's an example for the regular grass block (vanilla_grass.json):

{
  "block": "minecraft:grass",
  "replaceBlock": "minecraft:air",
  "iterations": 128,
  "applyMode": "BONEMEAL",
  "genDensity": 0,
  "biomes": [
    "minecraft:plains",
    "minecraft:forest"
  ],
  "dimensions": [
    0
  ],
  "spawnBlocks": [
    {
      "block": "minecraft:tallgrass[type=tall_grass]",
      "weight": 60
    },
    {
      "block": "flowerEntry",
      "weight": 20
    }
  ]
}

Configuration parameters

• block: Block to apply custom bone meal logic to (must be IGrowable)
• replaceBlock: Block that will be replaced with vegetation (above the specified block). Can be omitted to replace air
• iterations: Density of generated blocks and plants
• applyMode: Application logic: BONEMEAL (when using bone meal, default), SURFACE (natural surface world generation), or BOTH (bone meal + world generation)
• genDensity: Number of generation cycles for surface world generation. Required when applyMode is SURFACE or BOTH
• biomes: Optional list of allowed biomes. Can be left empty to work everywhere
• dimensions: Optional list of allowed dimensions. Can be left empty to work everywhere
• spawnBlocks: Array of blocks and plants to spawn on the specified block. flowerEntry selects a random flower
• weight: Relative spawn chance among all entries in spawnBlocks

The mod was created for Minecraft version 1.12.2.
