# AnimationLibraryComponent.AnimationCollection

A collection of animations an entity can play.

## Declaration

```swift
struct AnimationCollection
```

## Overview

Overview You use AnimationCollection to access animations in an AnimationLibraryComponent. The initializers for AnimationLibraryComponent create an AnimationCollection, so you don’t need to create one directly. You can access the collection with the animations property.
