# AnimationTimingFunction

The pacing of an animation transition.

## Declaration

```swift
struct AnimationTimingFunction
```

## Overview

Overview Use an animation timing function to control the pace of an animation transition when you call one of an entity’s animated move methods, like Entity/move(to:relativeTo:duration:timingFunction:)-905k. If you omit a timing function from the call, the method uses the default timing function.
