# ActionMarkupHandler

Class in [Yarn.Unity](/3.1/api/csharp/yarn.unity.md)

Inherits from `UnityEngine.MonoBehaviour`

## Summary

This is an abstract monobehaviour that conforms to the [IActionMarkupHandler](/3.1/api/csharp/yarn.unity/yarn.unity.iactionmarkuphandler.md) interface.

```csharp
public abstract class ActionMarkupHandler : MonoBehaviour, IActionMarkupHandler
```

## Remarks

Intended to be used in situations where you require a monobehaviour version of the interfaces. This is used by [LinePresenter](/3.1/api/csharp/yarn.unity/yarn.unity.linepresenter.md) to have a list of handlers that can be connected up via the inspector.
