Implementations

impl StructureGenerator

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

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, ) -> StructureGenerator

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, ) -> StructureGenerator

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, ) -> StructureGenerator

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

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

Template pool registry used by structure contexts.

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

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.
