Animator

class Animator(uiElement: UIElement)

The Animator class is responsible for a UIElement animations

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

The animator modifies the uiElement transformations, like UIElement.scale, UIElement.translateBy, UIElement.rotate, according to its configuration

NOTE:

Applying additional transformations during animation may result in unexpected behavior
When the animation has ended, consider calling UIElement.resetTransformations to reset the transformation state or apply the new position to the UIElement, for example, by passing the Animator.getCurrentX value to the UIElement.setX method

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

Animation might be laggy when uploading assets to the glasses (like images and fonts)

Constructors

constructor(uiElement: UIElement)

Types

IEvsAnimationListener

interface IEvsAnimationListener

Interface for receiving animation events

Functions

fun blink(intervalMs: Long): Animator

Start blinking the ui element every intervalMs

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

Start blinking the ui element

fun bounce(): Animator

The animation will reverse infinitely, until cancel is called

fun cancel(): Animator

Cancels the animation.

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

fun getCurrentX(): Float?

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

fun getCurrentY(): Float?

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

fun getProgress(): Float

Receive the current animation progress 0,1

fun isBlinking(): Boolean

Returns true if the UIElement is blinking

fun isStarted(): Boolean

Indicates if the animation is active.

fun register(listener: Animator.IEvsAnimationListener): Animator

Register for animation events.

fun repeat(): Animator

The animation will repeat infinitely, until cancel is called

fun reverse(): Animator

The animation will reverse ONCE before end

fun rotate(angleDegrees: Float): Animator

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

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