# EmphasizeAction

An action that performs an animation to call attention to an entity.

## Declaration

```swift
struct EmphasizeAction
```

## Overview

Overview This action plays a preexisting animation, dependent on the style and motionType options. The example below creates an animation that causes the entity to bounce in a playful style. // An action that performs a bounce motion in a playful style. let emphasizeAction = EmphasizeAction(motionType: .bounce,                                       style: .playful,                                       isAdditive: false)

// A five second animation that plays the preexisting animation. // // This animation causes the entity to raise up, and then drop, // appearing to bounce on the ground in a playful style, // before returning to its original position. let playfulBounceAnimation = try AnimationResource     .makeActionAnimation(for: emphasizeAction,                          duration: 5.0,                          bindTarget: .transform)

// Play the five second emphasize animation that causes the entity to // bounce in a playful style. entity.playAnimation(playfulBounceAnimation) important: This action directly animates the BindTarget.transform on the bound entity. Ensure a correct bind target is supplied when creating the animation.
