Sub‐Biome Placement

Add Sub-Biomes

Adding a sub-biome requires the relevant dimension key, the biome key of the target biome to replace, the biome key of the biome to replace it with, and a criterion indicating the conditions for replacement of the target biome. Sub-biomes can target replacement biomes as well as vanilla/data biomes.

in code

• Methods: addSubOverworld, addSubNether, addSubEnd
• See also: criterion

// Adding Old Growth Pine Taiga as a sub-biome in the noise-based center of the Desert biome.
BiomePlacement.addSubOverworld(
        BiomeKeys.DESERT,
        BiomeKeys.OLD_GROWTH_PINE_TAIGA,
        CriterionBuilder.ratioMax(
                RatioTargets.CENTER,
                0.2f));

// Adding our End midlands biome adjacent to its matching highlands biome.
BiomePlacement.addSubEnd(
        BiomeKeys.END_MIDLANDS,
        midlands,
        CriterionBuilder.alternate(
                highlands,
                BiomeKeys.END_HIGHLANDS));

// Adding a forest clearing sub-biome to a forest, based on PV noise.
BiomePlacement.addSubOverworld(
        myforest,
        myclearing,
        CriterionBuilder.deviationMin(
                BiomeParameterTargets.PEAKS_VALLEYS,
                0.05d));
