# AnimationEvents

Notable milestones that the framework signals during animation playback.

## Declaration

```swift
enum AnimationEvents
```

## Overview

Overview This enumeration defines the playback states that an animated entity can indicate to an app. To receive notification of a particular event, create a completion handler: private func onAnimationCompleted(_ event:     AnimationEvents.PlaybackCompleted) {         // Define code that runs when the animation completes. } Then, subscribe the handler on the entity for the state of interest: // Get an animation. let animationName = entity.availableAnimations.first!.name!

// Pass the animation to an entity and get a controller. entity.playAnimation(named: animationName, transitionDuration: 0.0)

entitySubscription = view.scene.publisher(for:     AnimationEvents.PlaybackCompleted.self, on: entity)         .sink(receiveValue: onAnimationCompleted)
