Expand description

A trait for generating chunks.

Required Methods§

Source

fn min_y(&self) -> i32

Returns the generator’s minimum Y coordinate.

Source

fn gen_depth(&self) -> i32

Returns the generator’s vertical generation depth in blocks.

Source

fn noise_biome(&self, quart_x: i32, quart_y: i32, quart_z: i32) -> BiomeRef

Returns the generator biome at one quart position without requiring a loaded chunk.

Source

fn create_structures(&self, chunk: &Chunk)

Creates the structures in a chunk.

Source

fn create_biomes(&self, chunk: &Chunk)

Creates the biomes in a chunk.

Source

fn fill_from_noise( &self, chunk: GenerationChunk<'_, NoisePhase>, beardifier: Option<&Beardifier>, )

Fills the chunk with noise.

beardifier carries pre-collected structure-piece terrain adaptation. The caller (production: noise stage; tests: harness) is responsible for walking the chunk’s structure references and building the beardifier — this trait stays free of any cross-chunk lookup. None skips the integration entirely (cheaper than passing an empty beardifier).

Source

fn build_surface( &self, chunk: GenerationChunk<'_, SurfacePhase>, neighbor_biomes: &dyn Fn(IVec3) -> u16, )

Builds the surface of the chunk.

neighbor_biomes maps (quart_x, quart_y, quart_z) to a biome palette ID, reading from neighbor chunk palettes for out-of-chunk biome lookups (matching vanilla’s WorldGenRegion.getNoiseBiome).
