# Enabled

> Controls whether this system executes when its OnUpdate function is called.

## Definition

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

```csharp
public bool Enabled { get; set; }
```

### Remarks

The Enabled property is intended for debugging so that you can easily turn on and off systems from the Entity Debugger window. A system with Enabled set to false will not update, even if its [ComponentSystemBase.ShouldRunSystem()](/engine/7000.0/script-reference/unity/entities/componentsystembase/shouldrunsystem.md) function returns true.
