Constructor

Phaser. Device

Detects device support capabilities and is responsible for device intialization - see 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 Phaser.Game begins its "boot" phase. Feature detection can be modified in the 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

<internal> new Device()

It is not possible to instantiate the Device class manually.

Public Properties

<static, nullable> onInitialized : Phaser.Signal

This signal is dispatched after device initialization occurs but before any of the ready callbacks (see whenReady) have been invoked.

Local "patching" for a particular device can/should be done in this event.

Note: This signal is removed after the device has been readied; if a handler has not been added before new Phaser.Game(..) it is probably too late.

Public Methods

<static> whenReady(handler, context, nonPrimer)

Add a device-ready handler and ensure the device ready sequence is started.

Phaser.Device will not activate or initialize until at least one whenReady handler is added, which is normally done automatically be calling new Phaser.Game(..).

The handler is invoked when the device is considered "ready", which may be immediately if the device is already "ready". See deviceReadyAt.

Parameters
Name Type Argument Default Description
handler function

Callback to invoke when the device is ready. It is invoked with the given context the Phaser.Device object is supplied as the first argument.
context object <optional>

Context in which to invoke the handler
nonPrimer boolean <optional>
 false

If true the device ready check will not be started.
Source code: system/Device.js (Line 536)

Parameters
Name Type Description
type string

One of 'mp3, 'ogg', 'm4a', 'wav', 'webm' or 'opus'.

isAndroidStockBrowser()

Detect if the host is a an Android Stock browser. This is available before the device "ready" event.

Authors might want to scale down on effects and switch to the CANVAS rendering method on those devices.

Source code: system/Device.js (Line 1297)
Example
var defaultRenderingMode = Phaser.Device.isAndroidStockBrowser() ? Phaser.CANVAS : Phaser.AUTO;

isConsoleOpen()

Check whether the console is open. Note that this only works in Firefox with Firebug and earlier versions of Chrome. It used to work in Chrome, but then they removed the ability: http://src.chromium.org/viewvc/blink?view=revision&revision=151136
