## IsComponentEnabled\<T>(Entity)

Checks whether a given [ComponentType](/engine/7000.0/script-reference/unity/entities/componenttype.md) is enabled on the specified [Entity](/engine/7000.0/script-reference/unity/entities/entity.md).

```csharp
public bool IsComponentEnabled<T>(Entity entity) where T : unmanaged, IEnableableComponent
```

### Parameters

**** (\[Entity]\(/engine/7000.0/script-reference/unity/entities/entity)): The entity whose component should be checked.

### Returns

| Type                                                          | Description                                                             |
| ------------------------------------------------------------- | ----------------------------------------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | True if the specified component is enabled, or false if it is disabled. |

### Remarks

An entity with a disabled component will not match an [EntityQuery](/engine/7000.0/script-reference/unity/entities/entityquery.md) that requires that component, and will match a query that excludes that component.

## IsComponentEnabled\<T>(SystemHandle)

Checks whether a given [ComponentType](/engine/7000.0/script-reference/unity/entities/componenttype.md) is enabled on the specified system using [SystemHandle](/engine/7000.0/script-reference/unity/entities/systemhandle.md).
