Used to represent a world's terrain. **Signature:** ```typescript export default class Chunk implements protocol.Serializable ``` **Implements:** protocol.Serializable ## Remarks Chunks make up the bulk of the terrain in a world. Chunks are fixed size, each containing 16^3 possible blocks as a 16x16x16 cube. Chunks are primarily a data structure used by [ChunkLattice](./server.chunklattice.md) to represent a world's terrain. Chunks store their internal block coordinates in local space, meaning local coordinates x: 0...15, y: 0...15, z: 0...15. ## Constructors

Constructor	Modifiers	Description
[(constructor)(originCoordinate)](./server.chunk._constructor_.md)		Creates a new chunk instance.

## Properties

Property	Modifiers	Type	Description
[blocks](./server.chunk.blocks.md)	`readonly`	Readonly<Uint8Array>	The blocks in the chunk as a flat Uint8Array\[4096\], each index as 0 or a block type id.
[originCoordinate](./server.chunk.origincoordinate.md)	`readonly`	[Vector3Like](./server.vector3like.md)	The origin coordinate of the chunk.
