# SetComponentEnabled

> Enable or disable the IComponentData of type T on the specified system using a SystemHandle. This operation does not cause a structural change (even if it occurs on a worker thread), or affect the value of the component. For the purposes of EntityQuery matching, a system with a disabled component will behave as if it does not have that component. The type T must implement the IEnableableComponent interface.

## Definition

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

## SetComponentEnabled(SystemHandle, bool)

Enable or disable the [IComponentData](/engine/7000.0/script-reference/unity/entities/icomponentdata.md) of type T on the specified system using a [SystemHandle](/engine/7000.0/script-reference/unity/entities/systemhandle.md). This operation does not cause a structural change (even if it occurs on a worker thread), or affect the value of the component. For the purposes of EntityQuery matching, a system with a disabled component will behave as if it does not have that component. The type T must implement the [IEnableableComponent](/engine/7000.0/script-reference/unity/entities/ienableablecomponent.md) interface.

```csharp
public void SetComponentEnabled(SystemHandle systemHandle, bool value)
```

### Parameters

**** (\[SystemHandle]\(/engine/7000.0/script-reference/unity/entities/systemhandle)): The system whose component should be enabled or disabled.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): True if the specified component should be enabled, or false if it should be disabled.

## SetComponentEnabled(Entity, bool)

Enable or disable the [IComponentData](/engine/7000.0/script-reference/unity/entities/icomponentdata.md) of type T on the specified [Entity](/engine/7000.0/script-reference/unity/entities/entity.md). This operation does not cause a structural change (even if it occurs on a worker thread), or affect the value of the component. For the purposes of EntityQuery matching, an entity with a disabled component will behave as if it does not have that component. The type T must implement the [IEnableableComponent](/engine/7000.0/script-reference/unity/entities/ienableablecomponent.md) interface.

```csharp
public void SetComponentEnabled(Entity entity, bool value)
```

### Parameters

**** (\[Entity]\(/engine/7000.0/script-reference/unity/entities/entity)): The entity whose component should be enabled or disabled.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): True if the specified component should be enabled, or false if it should be disabled.
