Animator

The Animator class is responsible for a UIElement animations

Each UIElement has a single UIElement.animator object that handles its animations

NOTE: upon animation end\cancel its state is reset

The SDK will do its best effort to perform animations as fast as possible, but the communication bandwidth and the amount of rendered elements may have an impact on the animation rendering performance

In addition, animation will not work properly when uploading assets to the glasses (like images and fonts)

It is recommended to read the SDK use guide for more information

Constructors

Animator

constructor(uiElement: UIElement)

Types

IEvsAnimationListener

interface IEvsAnimationListener

Interface for receiving animation events

Functions

blink

fun blink(intervalMs: Long): Animator

Start blinking the ui element every intervalMs

fun blink(intervalOffMs: Long, intervalOnMs: Long): Animator

Start blinking the ui element

bounce

fun bounce(): Animator

The animation will reverse infinitely, until cancel is called

cancel

fun cancel(): Animator

Cancels the animation.

duration

fun duration(ms: Int): Animator

Sets the animation duration in milliseconds. Default is 1000ms

estimatePositionAt

fun estimatePositionAt(timestamp: Long): Point

Helper function to estimate to animator translation x,y position at a certain percent

getCurrentAngle

fun getCurrentAngle(): Float?

Receive the current rotation associated with the current animation progress getProgress

getCurrentScaleX

fun getCurrentScaleX(): Float?

Receive the current scale x associated with the current animation progress getProgress

getCurrentScaleY

fun getCurrentScaleY(): Float?

Receive the current scale y associated with the current animation progress getProgress

getCurrentX

fun getCurrentX(): Float?

Receive the current x position associated with the current animation progress getProgress

getCurrentY

fun getCurrentY(): Float?

Receive the current y position associated with the current animation progress getProgress

getProgress

fun getProgress(): Float

Receive the current animation progress 0,1

isBlinking

fun isBlinking(): Boolean

Returns true if the UIElement is blinking

isStarted

fun isStarted(): Boolean

Indicates if the animation is active.

fun register(listener: Animator.IEvsAnimationListener): Animator

repeat

fun repeat(): Animator

fun rotate(angleDegrees: Float, px: Float, py: Float): Animator

fun rotate(angleDegrees: Float, px: Float, py: Float, pivot: Pivot): Animator

Sets the target rotation angle animation value

scale

fun scale(scaleFactor: Float): Animator

Sets the target scale x and y animation values

scaleX

fun scaleX(scaleFactor: Float): Animator
