|

|
|
* @classdesc
|
|
* Phaser.Game has a single instance of the TweenManager through which all Tween objects are created and updated.
|
|
* Tweens are hooked into the game clock and pause system, adjusting based on the game state.
|
|
*
|
|
* TweenManager is based heavily on tween.js by http://soledadpenades.com.
|
|
* The difference being that tweens belong to a games instance of TweenManager, rather than to a global TWEEN object.
|
|
* It also has callbacks swapped for Signals and a few issues patched with regard to properties and completion errors.
|
|
* Please see https://github.com/sole/tween.js for a full list of contributors.
