# Class sfUnityEventDispatcher

Namespace: [KS.SceneFusion.Client.Unity.Editor](/scene-fusion/api-reference/ks.scenefusion.client.unity.editor.md)\
Assembly: KSUnity-Source.dll

Listens for and dispatches Unity events, in some cases changing the parameters of the event. Allows all events to be enabled or disabled. Register with this class instead of directly against the Unity events to ensure you do not respond to events that were triggered by Scene Fusion.

```csharp
public class sfUnityEventDispatcher
