What a biome modifier does to its biomes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AddFeatures

add_features: append placed features to one generation step.

Fields

features: Vec<String>

Placed feature ids (mymod:ore) or tags (#mymod:tag).

step: String

The generation step (underground_ores, …).

RemoveFeatures

remove_features: take placed features out of generation steps.

Fields

features: Vec<String>

Placed feature ids or tags.

steps: Vec<String>

The steps to take them out of; none means every step.

AddSpawns

add_spawns: append spawners to their entity types’ spawn categories.

Fields

spawners: Vec<BiomeModifierSpawner>

The spawners to add.

RemoveSpawns

remove_spawns: take entity types out of every spawn category.

Fields

entity_types: Vec<String>

Entity type ids or tags.

AddSpawnCosts

add_spawn_costs: set the spawn cost of entity types.

Fields

entity_types: Vec<String>

Entity type ids or tags.

energy_budget: f64

The energy_budget of the cost.

charge: f64

The charge of the cost.

RemoveSpawnCosts

remove_spawn_costs: take entity types out of spawn_costs.

Fields

entity_types: Vec<String>

Entity type ids or tags.

AddCarvers

add_carvers: append configured carvers to the biome’s carvers.

Fields

carvers: Vec<String>

Configured carver ids (mymod:pit) or tags.

RemoveCarvers

remove_carvers: take configured carvers out of the biome’s carvers.

Fields

carvers: Vec<String>

Configured carver ids or tags.

ModifyBiome

horizon:modify_biome (NeoForge’s MODIFY phase): set single values of the biome, after every addition and removal. A None leaves the value as it is.

Fields

temperature: Option<f64>

temperature.

downfall: Option<f64>

downfall.

has_precipitation: Option<bool>

has_precipitation.

temperature_modifier: Option<String>

temperature_modifier: none or frozen.

sky_color: Option<u32>

effects.sky_color, 24-bit RGB (0..=0xFFFFFF).

fog_color: Option<u32>

effects.fog_color, 24-bit RGB.

water_color: Option<u32>

effects.water_color, 24-bit RGB.

water_fog_color: Option<u32>

effects.water_fog_color, 24-bit RGB.

foliage_color: Option<BiomeColourChange>

effects.foliage_color: set it or remove the override.

dry_foliage_color: Option<BiomeColourChange>

effects.dry_foliage_color: set it or remove the override.

grass_color: Option<BiomeColourChange>

effects.grass_color: set it or remove the override.

ambient_particles: Option<Vec<BiomeAmbientParticle>>

minecraft:visual/ambient_particles: replaces the biome’s particles (an empty list removes them).

ambient_loop: Option<String>

loop of minecraft:audio/ambient_sounds. Setting this, ambient_mood or ambient_additions replaces the biome’s whole ambient sounds value with the ones set.

ambient_additions: Option<Vec<BiomeAmbientAddition>>

additions of minecraft:audio/ambient_sounds.

ambient_mood: Option<BiomeAmbientMood>

mood of minecraft:audio/ambient_sounds.

background_music: Option<BiomeMusic>

default of minecraft:audio/background_music; replaces the whole value, so the biome’s creative and underwater music go.

music_volume: Option<f64>

minecraft:audio/music_volume, 0.0..=1.0.
