# DialogueViewBase

Class in [Yarn.Unity](/2.0/api/csharp/yarn.unity.md)

Inherits from `MonoBehaviour`

## Summary

A `MonoBehaviour` that can present the data of a dialogue executed by a [DialogueRunner](/2.0/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) to the user. The [DialogueRunner](/2.0/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) uses subclasses of this type to relay information to and from the user, and to pause and resume the execution of the `YarnScript` .

```csharp
public abstract class DialogueViewBase : MonoBehaviour
```

## Remarks

The term "view" is meant in the broadest sense, e.g. a view on the dialogue (MVVM pattern). Therefore, this abstract class only defines how a specific view on the dialogue should communicate with the [DialogueRunner](/2.0/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) (e.g. display text or trigger a voice over clip). How to present the content to the user will be the responsibility of all classes inheriting from this class.

The inheriting classes will receive a [LocalizedLine](/2.0/api/csharp/yarn.unity/yarn.unity.localizedline.md) and can be in one of the stages defined in `DialogueLineStatus` while presenting it.
