Chunk

Remarks

Sixteen kilobytes by default, which is what fits comfortably in L1 on every target after the entity column is accounted for, and what Arch and DOTS both converged on. A system that reads two of an archetype's eight components touches only those two columns, so the bytes the cache pulls in are bytes the loop uses — which is the entire reason this layout exists.

The whole chunk is one byte[]: the entity column first, then one column per non-tag component, each aligned. Tags occupy no column, only a bit in the archetype's mask.

Fields and properties (5)

• public Archetype Archetype

  The archetype every entity in here belongs to.

• public int Count

  How many entities are in the chunk.

• public int Capacity

  How many it has room for.

• public bool IsFull

  Whether there is no room for another entity.

• public ReadOnlySpan<Entity> Entities

  The entities in the chunk, in row order.

Methods (3)

• public Span<T> Values<T>()

  One component's values for every entity in this chunk, for writing. Marks the column changed at the world's current version.

• public ReadOnlySpan<T> ReadValues<T>()

  One component's values for every entity in this chunk, for reading.

• public uint VersionOf(int column)

  The version at which a column was last handed out for writing.
