/**
|
|
* The Phaser.Game object is the main controller for the entire Phaser game. It is responsible
|
|
* for handling the boot process, parsing the configuration values, creating the renderer,
|
|
* and setting-up all of the Phaser systems, such as physics, sound and input.
|
|
* Once that is complete it will start the default State, and then begin the main game loop.
|
|
*
|
|
* You can access lots of the Phaser systems via the properties on the `game` object. For
|
|
* example `game.renderer` is the Renderer, `game.sound` is the Sound Manager, and so on.
|
|
*
|
|
* Anywhere you can access the `game` property, you can access all of these core systems.
|
|
* For example a Sprite has a `game` property, allowing you to talk to the various parts
|
|
* of Phaser directly, without having to look after your own references.
|
|
*
|
|
* In it's most simplest form, a Phaser game can be created by providing the arguments
|
|
* to the constructor:
|
|
*
|
|
* ```
|
|
* var game = new Phaser.Game(800, 600, Phaser.AUTO, '', { preload: preload, create: create });
|
|
* ```
|
|
*
|
|
* In the example above it is passing in a State object directly. You can also use the State
|
|
* Manager to do this:
|
|
*
|
|
* ```
|
|
* var game = new Phaser.Game(800, 600, Phaser.AUTO);
|
|
* game.state.add('Boot', BasicGame.Boot);
|
|
* game.state.add('Preloader', BasicGame.Preloader);
|
|
* game.state.add('MainMenu', BasicGame.MainMenu);
|
|
* game.state.add('Game', BasicGame.Game);
|
|
* game.state.start('Boot');
|
|
*
|
|
* ```
|
|
* In the example above, 4 States are added to the State Manager, and Phaser is told to
|
|
* start running the `Boot` state when it has finished initializing. There are example
|
|
* project templates you can use in the Phaser GitHub repo, inside the `resources` folder.
|
|
*
|
|
* Instead of specifying arguments you can also pass a single object instead:
|
|
*
|
|
* ```
|
|
* var config = {
|
|
* width: 800,
|
|
* height: 600,
|
|
* renderer: Phaser.AUTO,
|
|
* antialias: true,
|
|
* multiTexture: true,
|
|
* state: {
|
|
* preload: preload,
|
|
* create: create,
|
|
* update: update
|
|
* }
|
|
* }
|
|
*
|
|
* var game = new Phaser.Game(config);
|
|
* ```
|
|
*
|
|
* @class Phaser.Game
|
|
* @constructor
|
|
* @param {number|string} [width=800] - The width of your game in game pixels. If given as a string the value must be between 0 and 100 and will be used as the percentage width of the parent container, or the browser window if no parent is given.
|
|
* @param {number|string} [height=600] - The height of your game in game pixels. If given as a string the value must be between 0 and 100 and will be used as the percentage height of the parent container, or the browser window if no parent is given.
|
|
* @param {number} [renderer=Phaser.AUTO] - Which renderer to use: Phaser.AUTO will auto-detect, Phaser.WEBGL, Phaser.WEBGL_MULTI, Phaser.CANVAS or Phaser.HEADLESS (no rendering at all).
|
|
* @param {string|HTMLElement} [parent=''] - The DOM element into which this games canvas will be injected. Either a DOM ID (string) or the element itself.
|
|
* @param {object} [state=null] - The default state object. A object consisting of Phaser.State functions (preload, create, update, render) or null.
|
|
* @param {boolean} [pixelArt=false] - Draw all image textures anti-aliased or not. The default is for smooth textures (false), but set to `true` if your game features all pixel art.
