public EntityQueryBuilder AddNone(ComponentType t)
```

### Parameters

**** (\[ComponentType]\(/engine/7000.0/script-reference/unity/entities/componenttype)): The component type

### Returns

| Type                                                                                       | Description                                  |

### Remarks

**Obsolete.** Use [EntityQueryBuilder.WithNone](/engine/7000.0/script-reference/unity/entities/entityquerybuilder/withnone.md) instead.

Add a "none" matching type to the current query. Types in the None list are never written to. If the AccessModeType field of the provided component type is [ComponentType.AccessMode.ReadWrite](/engine/7000.0/script-reference/unity/entities/componenttype/accessmode/readwrite.md), will be forced to [NativeArray\<T>.ReadOnly](/engine/7000.0/script-reference/unity/collections/nativearray1/readonly.md) in the query.
