## Definition

* **Type:** Method
* **Namespace:** [Unity.Entities](/engine/7000.0/script-reference/unity/entities.md)
* **Assembly:** UnityEngine.EntitiesModule

```csharp
public SystemAPIQueryBuilder WithAnyChunkComponentRW<T>()
```

### Returns

| Type                                                                                             | Description                                  |
| ------------------------------------------------------------------------------------------------ | -------------------------------------------- |
| [SystemAPIQueryBuilder](/engine/7000.0/script-reference/unity/entities/systemapiquerybuilder.md) | The builder object that invoked this method. |

### Remarks

To match the resulting query, an Entity must have at least one of the query's optional component types, specified using either [SystemAPIQueryBuilder.WithAny](/engine/7000.0/script-reference/unity/entities/systemapiquerybuilder/withany.md) or [SystemAPIQueryBuilder.WithAnyChunkComponent](/engine/7000.0/script-reference/unity/entities/systemapiquerybuilder/withanychunkcomponent.md). Chunk components are a distinct component type, which are different from adding the same type as a standard component.

To add additional optional Chunk Components, call this method multiple times.
