Implementations

impl<'a, 'b> FuzzedBiomeColumn<'a, 'b>

pub(super) fn new( quarts: &'a mut SurfaceQuartBiomes<'b>, classes: Option<&'a SurfaceBiomeClasses>, biome_zoom_seed: i64, block_x: i32, block_z: i32, ) -> Self

fn compute_cy_group(&mut self, cy: i32, high: bool)

fill the low or high y slots for this candidate group

fn recompute_candidates(&mut self, parent_y: i32)

refresh candidates for this parent y

pub(super) fn get(&mut self, block_y: i32) -> u16

exact fuzzed biome at this y

pub(super) fn get_for_surface_rule(&mut self, block_y: i32) -> u16

A biome the surface rule cannot distinguish from Self::get’s.

pub(super) fn below_preliminary_outcome( &mut self, block_y: i32, ) -> PartialSurfaceOutcome

resolve below the preliminary surface using y and a shared biome class

fn uniform_group_biome(&mut self, block_y: i32) -> Option<u16>

The group’s shared-class candidate biome, if its 8 candidates agree.

fn uniform_candidate_biome( &mut self, classes: &SurfaceBiomeClasses, parent_y: i32, ) -> Option<u16>

Trait Implementations

impl SurfaceBiomeProvider for FuzzedBiomeColumn<'_, '_>

fn biome_id(&mut self, block_y: i32) -> u16

Returns the biome ID for the given block Y in the current X/Z column.
