Struct VoxelChunk 

pub struct VoxelChunk {
    pub asset_id: AssetId,
    pub palette: Vec<AssetId>,
    pub dim: [u32; 3],
    pub block_size: f32,
    pub blocks: Vec<u32>,
    pub lod_levels: u32,
    pub lod_distances: Vec<f32>,
    pub locator: Option<PayloadLocator>,
}

A voxel grid that compiles into a single mesh.

A dense grid of blocks compiled into a single mesh at build time. Use one chunk per region of a voxel/Minecraft-style world; reference it from a Prop’s mesh field. Hidden faces between two solid blocks are dropped, so a fully filled chunk contributes zero triangles to its interior.

The palette must contain at least one entry whose BlockType has solid: false (typically named air); cells whose palette entry is non-solid emit no faces. Faces are only emitted between a solid block and either an empty neighbour or the outside of the chunk.

Fields

asset_id: AssetId

Asset identity; injected via inject_name. Not part of args.

palette: Vec<AssetId>

BlockType asset names. blocks[i] is an index into this list.

dim: [u32; 3]

Chunk dimensions [dx, dy, dz] in blocks.

block_size: f32

World units per block edge.

blocks: Vec<u32>

Flat block array, length dx*dy*dz. Index = x + y*dx + z*dx*dy.

lod_levels: u32

Number of level-of-detail versions to generate, including the original. 1 (the default) generates none.

lod_distances: Vec<f32>

Camera distances at which to switch to each lower-detail version; empty lets the build choose defaults.

locator: Option<PayloadLocator>

Injected at load time from the compiled blob payload.

Trait Implementations

impl Clone for VoxelChunk

fn clone(&self) -> VoxelChunk

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for VoxelChunk

const NAME: &'static str = "VoxelChunk"

The registry name a world authors this component under.

fn inject_locator(&mut self, locator: PayloadLocator)

Called after construction to inject the payload locator from the blob def. Only meaningful for components with a compiled payload. The default implementation does nothing (correct for most components).

fn inject_name(&mut self, id: AssetId)

Called after construction to inject the asset’s identity from the blob def. Only meaningful for components that look themselves up by id at runtime. The default implementation does nothing.

fn from_baked(bytes: &[u8]) -> Result<VoxelChunk, CnResult>

Reconstruct this component from a blob record, whose bytes are the serialized runtime component (cook already ran the asset -> component translation). The default rejects: runtime-only components are never stored in a blob, so only loadable types provide an implementation.

impl ComponentSlot for VoxelChunk

const DISCRIMINANT: u8

The component type’s stable id, used as its ComponentId.

fn slot(s: &ComponentStorage) -> &Column<VoxelChunk>

Borrow this type’s column out of the storage.

fn slot_mut(s: &mut ComponentStorage) -> &mut Column<VoxelChunk>

Mutably borrow this type’s column out of the storage.

impl Debug for VoxelChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for VoxelChunk

fn default() -> VoxelChunk

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VoxelChunk

where VoxelChunk: Default,

fn deserialize<__D>( __deserializer: __D, ) -> Result<VoxelChunk, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<VoxelChunk> for ComponentAsset

fn from(c: VoxelChunk) -> ComponentAsset

Converts to this type from the input type.

impl RuntimeComponent for VoxelChunk

impl Serialize for VoxelChunk

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
