Implementations

impl StructureGenerator

pub fn vanilla( seed: i64, world_path: Option<&Path>, biome_provider: &(impl StructureBiomeProvider + Sync), thread_pool: &ThreadPool, ) -> Self

Creates a structure generator over all vanilla structure sets.

pub fn vanilla_with_structure_sets( seed: i64, world_path: Option<&Path>, biome_provider: &(impl StructureBiomeProvider + Sync), structure_sets: Vec<(Identifier, StructureSet)>, thread_pool: &ThreadPool, ) -> Self

Creates a generator over an explicit structure-set list while keeping all template pools, templates, and structure implementation dispatch vanilla.

pub fn vanilla_flat_with_structure_sets( seed: i64, world_path: Option<&Path>, biome_provider: &(impl StructureBiomeProvider + Sync), structure_sets: Vec<(Identifier, StructureSet)>, thread_pool: &ThreadPool, ) -> Self

Creates a vanilla superflat structure generator.

Vanilla superflat uses the level seed for random-spread placement and structure selection, but always seeds concentric-ring positions with 0L.

pub fn with_assets( seed: i64, world_path: Option<&Path>, biome_provider: &(impl StructureBiomeProvider + Sync), structure_sets: Vec<(Identifier, StructureSet)>, assets: StructureGeneratorAssets, thread_pool: &ThreadPool, ) -> Self

Creates a generator from explicit structure sets and explicit runtime assets.

fn with_assets_for_ring_seed( seed: i64, ring_position_seed: i64, world_path: Option<&Path>, biome_provider: &(impl StructureBiomeProvider + Sync), structure_sets: Vec<(Identifier, StructureSet)>, assets: StructureGeneratorAssets, thread_pool: &ThreadPool, ) -> Self

pub const fn template_pools(&self) -> &FxHashMap<Identifier, TemplatePoolData>

Template pool registry used by structure contexts.

pub const fn templates(&self) -> &FxHashMap<Identifier, TemplateData>

Structure templates used by structure contexts.

pub fn locate_plan_for_structures( &self, structures: &[Identifier], ) -> Option<StructureLocatePlan>

Builds a detached locate plan for one or more structure ids.

pub fn generate_starts_for_chunk( &self, ctx: &mut dyn StructureGenerationContext, has_existing_start: impl FnMut(&Identifier) -> bool, ) -> Vec<StructureStart>

Generates structure starts for one chunk.

fn rings_for_set(&self, set_key: &Identifier) -> Option<&[ChunkPos]>

fn is_structure_chunk_for_set( &self, set_key: &Identifier, source_x: i32, source_z: i32, stack: &mut Vec<Identifier>, ) -> bool

fn is_excluded( &self, placement: &StructurePlacement, source_x: i32, source_z: i32, stack: &mut Vec<Identifier>, ) -> bool

fn select_structure( &self, set: &StructureSet, ctx: &mut dyn StructureGenerationContext, ) -> Option<(StructureRef, GenerationStub)>

fn try_generate_entry( &self, entry: &StructureSelectionEntry, ctx: &mut dyn StructureGenerationContext, ) -> Option<(StructureRef, GenerationStub)>
