SparkTween

A tiny teeny tween function for SparkAR

by chrisError

https://pl.ai

make sure to add the following to which ever scripts need to use SparkTween

const { Tween, Ease, SparkTweener } = require("./tween.js");

Tween(startVal, endVal, duration, loopCount, mirror, ease, completeCallback)

startVal - start value for tween

endVal - end value for tween

duration - length of time for tween (in seconds)

loopCount - how many times should the tween loop (-1 for infinite)

mirror - bool - should the tween yoyo

ease - ease type [see enum for supported eases]

completeCallback - method to call on complete

breaking changes from previous version

please note the .animation when setting the tween to a property

SIMPLE USAGE (using the tween directly)

var sceneObject = Scene.root.find("MySceneObject);

sceneObject.transform.y = Tween(0.35, 2, 4, -1, false, Ease.LINEAR, null).animation;

EXTENDED FUNCIONALITY

var sceneObject = Scene.root.find("MySceneObject);

var tween = Tween(0.35, 2, 4, -1, false, Ease.LINEAR, null);

sceneObject.transform.y = tween.animation;

tween.Kill(); //CALL THIS WHEN YOU WANT TO KILL THE TWEEN

tweens also now support infinite loops by passing -1 as the loopCount
