Struct ArchetypeChunk
A block of unmanaged memory containing the components for entities sharing the same Archetype.
Namespace: Unity.Entities
Syntax
public struct ArchetypeChunk : IEquatable<ArchetypeChunk>Properties
| Name | Description |
|---|---|
| Archetype | The archetype of the entities stored in this chunk. |
| Capacity | The number of entities that can fit in this chunk. |
| ChunkEntityCount | The number of entities currently stored in the chunk (ignoring any sub-batching) |
| Count | If the ArchetypeChunk is not sub-batched, returns the number of entities in the chunk. Otherwise, returns the number of entities referenced by this batch. |
| Full | Whether this chunk is exactly full. |
| Null | A special "null" ArchetypeChunk that you can use to test whether ArchetypeChunk instances are valid. |
