# Start()

> Starts the EventService so it listens to new messages.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor.MPE](/engine/6000.7/script-reference/unityeditor/mpe.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public static void Start()
```

### Remarks

Normally, Start is called automatically when a member of the EventService is invoked. However, you may sometimes need to call it explicitly. For example, if you called [EventService.Close](/engine/6000.7/script-reference/unityeditor/mpe/eventservice/close.md) you can use Start to restart the EventService.
