# OnDialogueCompleteAsync()

Method in [DialoguePresenterBase](/3.1/api/csharp/yarn.unity/yarn.unity.dialoguepresenterbase.md)

## Summary

Called by the [DialogueRunner](/3.1/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) to signal that the dialogue has ended, and no more lines will be delivered.

```csharp
public abstract YarnTask OnDialogueCompleteAsync();
```

## Remarks

This method is called after the last piece of content (that is, lines, options or commands) finished running.

This method is a good place to perform tasks like dismissing on-screen dialogue UI (for example, turning off a letterboxing effect, or hiding dialogue UI elements.)

A task that represents any work done by this dialogue presenter in order to clean up after running dialogue.
