# LineAdvancer

Class in [Yarn.Unity](/api/csharp/yarn.unity.md)

Inherits from [`DialoguePresenterBase`](/api/csharp/yarn.unity/yarn.unity.dialoguepresenterbase.md)

## Summary

A dialogue presenter that listens for user input and sends requests to a [DialogueRunner](/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) to advance the presentation of the current line, either by asking a dialogue runner to hurry up its delivery, advance to the next line, or cancel the entire dialogue session.

```csharp
public sealed class LineAdvancer : DialoguePresenterBase, IActionMarkupHandler
```
