Entity spawn configuration - Slexom/earth2java GitHub Wiki

In Earth2Java any creature can be set on your preferred biome. Based on the mod loader you are using the procedure can be different

Add biomes to entity spawn

You can set the spawn biome of any creature by modifying the file earthtojavamobs.json in the config folder. Any entity object have a field called spawnBiomes that accept a list of strings. Those strings can be a Biome Identifier or a Biome Category. Both kind of entries can be used together.

Biome Identifier

Is a string identifying a registered biome. For vanilla biomes it is in the form of minecraft:name_of_the_biome.

Example

The following example will set the Rainbow Sheep on Plains, Sunflower Plains, Forest, Wooded Hills and Flower Forest biomes.

"rainbowSheep": {
    ...
    "spawnBiomes": [
      "minecraft:plains",
      "minecraft:sunflower_plains",
      "minecraft:forest",
      "minecraft:wooded_hills",
      "minecraft:flower_forest"
    ]
  },

Biome Category

It define a cateogry for biomes. Using one, or more, of those types will let the creature spawn in any biome, vanilla or modded, marked with that category.

Example

The following config will set the Pink Footed Pig on any biome marked as PLAINS.

"pinkFootedPig": {
    ...
    "spawnBiomes": [
      "plains"
    ]
  },

Builtin values

Blacklist a biome

Only Fabric version currently support this feature, Forge version will receive it on the next update and this warning will be removed

Using Biome Category or BiomeDictionary could have the creature to spawn on an unwanted biome. To avoid this you can blacklist the biome for that creature by adding an exclamation mark ! before the biome identifier.

Example

The following config will set the Pink Footed Pig on any biome marked as PLAINS, FOREST, except the Flower Forest.

"pinkFootedPig": {
    ...
    "spawnBiomes": [
      "plains",
      "forest",
      "!minecraft:flower_forest
    ]
  },
