Tween#from()

from(properties, duration, ease, autoStart, delay, repeat, yoyo) → {Phaser.Tween}

Sets this tween to be a from tween on the properties given. A from tween sets the target to the destination value and tweens to its current value.
For example a Sprite with an x coordinate of 100 tweened from x 500 would be set to x 500 and then tweened to x 100 by giving a properties object of { x: 500 }.
The ease function allows you define the rate of change. You can pass either a function such as Phaser.Easing.Circular.Out or a string such as "Circ".
".easeIn", ".easeOut" and "easeInOut" variants are all supported for all ease types.

Parameters

Name	Type	Argument	Default	Description
`properties`	object			An object containing the properties you want to tween., such as `Sprite.x` or `Sound.volume`. Given as a JavaScript object.
`duration`	number	<optional>	1000	Duration of this tween in ms. Or if `Tween.frameBased` is true this represents the number of frames that should elapse.
`ease`	function \| string	<optional>	null	Easing function. If not set it will default to Phaser.Easing.Default, which is Phaser.Easing.Linear.None by default but can be over-ridden.
`autoStart`	boolean	<optional>	false	Set to `true` to allow this tween to start automatically. Otherwise call Tween.start().
`delay`	number	<optional>	0	Delay before this tween will start in milliseconds. Defaults to 0, no delay.
`repeat`	number	<optional>	0	Should the tween automatically restart once complete? If you want it to run forever set as -1. This only effects this individual tween, not any chained tweens.
`yoyo`	boolean	<optional>	false	A tween that yoyos will reverse itself and play backwards automatically. A yoyo'd tween doesn't fire the Tween.onComplete event, so listen for Tween.onLoop instead.

Returns

Phaser.Tween -

This Tween object.
