2014-11-25 00:23:44 +00:00
* A Tween allows you to alter one or more properties of a target object over a defined period of time.
* This can be used for things such as alpha fading Sprites, scaling them or motion.
* Use `Tween.to` or `Tween.from` to set-up the tween values. You can create multiple tweens on the same object
* by calling Tween.to multiple times on the same Tween. Additional tweens specified in this way become "child" tweens and
* are played through in sequence. You can use Tween.timeScale and Tween.reverse to control the playback of this Tween and all of its children.

* 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.

* @param {function|string} [ease=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.
* @param {boolean} [autoStart=false] - Set to `true` to allow this tween to start automatically. Otherwise call Tween.start().
* @param {number} [delay=0] - Delay before this tween will start in milliseconds. Defaults to 0, no delay.
* @param {number} [repeat=0] - Should the tween automatically restart once complete? If you want it to run forever set as -1. This only effects this induvidual tween, not any chained tweens.
