}

A chunk generator for vanilla (normal) world generation.

Matches vanilla’s NoiseBasedChunkGenerator. The biome source is pluggable per-dimension — overworld, nether, and end each provide a different BiomeSourceKind variant.

Generic over N: DimensionNoises to support different dimensions with their own transpiled density functions and noise settings.

Fields

biome_source: BiomeSourceKind

Biome source for this dimension. Determines biomes at each quart position.

uniform_carver_biome: Option<BiomeRef>

Representative biome for source-carver lookup when every possible biome from biome_source has the same carver list.

Vanilla still samples each source biome in apply_carvers; Steel skips that sampling only when the source’s full possible-biome set proves the carver list is uniform. If future biome sources can produce mixed carver lists this remains None and the vanilla per-source lookup is used.

noises: Box<N>

Noise generators for this dimension’s density functions. Boxed because noise structs can be large.

splitter: RandomSplitter

Seed positional splitter for per-chunk construction of aquifers.

ore_veinifier: Option<OreVeinifier>

Ore vein generator for replacing stone with ore blocks.

surface_system: SurfaceSystem

Surface system for biome-specific block replacement.

surface_extension_biomes: SurfaceExtensionBiomes

Which vanilla surface extension biomes this source can produce.

default_block_id: BlockStateId

Block state ID for the default block, cached at construction time.

biome_zoom_seed: i64

Obfuscated seed for BiomeManager biome zoom fuzzing.

seed: i64

World seed as i64 (matching Java’s long), used for structures and carver seeding.

structure_generator: StructureGenerator

Shared structure placement/selection engine.

feature_runner: FeatureDecorationRunner

Cached placed-feature order for biome decoration.

_phantom: PhantomData<N>

Implementations

impl<N: DimensionNoises> VanillaGenerator<N>

pub fn new( world_path: Option<&Path>, biome_source: BiomeSourceKind, seed: u64, thread_pool: &ThreadPool, ) -> Self

Creates a new VanillaGenerator with the given biome source and seed.

Panics

Panics if SHA-256 hash output is shorter than 8 bytes (cannot happen).

fn initial_spawn_search_origin(&self) -> BlockPos

Returns the climate-selected origin used by vanilla before searching for a safe spawn chunk.

fn structure_generator(&self) -> Option<&StructureGenerator>

Returns the structure generator used for placement and locate queries.

fn create_structures(&self, chunk: &Chunk)

Creates the structures in a chunk.

fn create_biomes(&self, chunk: &Chunk)
