* @classdesc
|
|
* Detects device support capabilities and is responsible for device initialization - see {@link Phaser.Device.whenReady whenReady}.
|
|
*
|
|
* This class represents a singleton object that can be accessed directly as `game.device`
|
|
* (or, as a fallback, `Phaser.Device` when a game instance is not available) without the need to instantiate it.
|
|
*
|
|
* Unless otherwise noted the device capabilities are only guaranteed after initialization. Initialization
|
|
* occurs automatically and is guaranteed complete before {@link Phaser.Game} begins its "boot" phase.
|
|
* Feature detection can be modified in the {@link Phaser.Device.onInitialized onInitialized} signal.
|
|
*
|
|
* When checking features using the exposed properties only the *truth-iness* of the value should be relied upon
|
|
* unless the documentation states otherwise: properties may return `false`, `''`, `null`, or even `undefined`
|
|
* when indicating the lack of a feature.
|
|
*
|
|
* Uses elements from System.js by MrDoob and Modernizr
|
|
*
|
|
* @description
|
|
* It is not possible to instantiate the Device class manually.
