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 sub-biome matcher indicating the conditions for replacement of the target biome. Sub-biomes can target replacement biomes as well as vanilla/data biomes.

// Adding Old Growth Pine Taiga as a sub-biome in the noise-based center of the Desert biome.

                CriterionTypes.RATIO,
                0.2f)));

// Adding our End midlands biome adjacent to its matching highlands biome.
BiomePlacement.addSubEnd(
        BiomeKeys.END_MIDLANDS,
        midlands,

                false)));

// Adding a forest clearing sub-biome to a forest, based on PV noise.
