# LineProviderBehaviour

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

Inherits from `UnityEngine.MonoBehaviour`

## Summary

A `UnityEngine.MonoBehaviour` that produces [LocalizedLine](/3.1/api/csharp/yarn.unity/yarn.unity.localizedline.md) s, for use in Dialogue Presenters.

```csharp
public abstract class LineProviderBehaviour : MonoBehaviour, ILineProvider
```

## Remarks

[DialogueRunner](/3.1/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) s use a [LineProviderBehaviour](/3.1/api/csharp/yarn.unity/yarn.unity.lineproviderbehaviour.md) to get [LocalizedLine](/3.1/api/csharp/yarn.unity/yarn.unity.localizedline.md) s, which contain the localized information that is presented to the player through dialogue presenters.
