Phaser Class: Game

new Game(width, height, renderer, parent, state, transparent, antialias, physicsConfig)

This is where the magic happens. The Game object is the heart of your game, providing quick access to common functions and handling the boot process.

"Hell, there are no rules here - we're trying to accomplish something." Thomas A. Edison

Parameters:

Name	Type	Argument	Default	Description
`width`	number \| string	<optional>	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.
`height`	number \| string	<optional>	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.
`renderer`	number	<optional>	Phaser.AUTO	Which renderer to use: Phaser.AUTO will auto-detect, Phaser.WEBGL, Phaser.CANVAS or Phaser.HEADLESS (no rendering at all).
`parent`	string \| HTMLElement	<optional>	''	The DOM element into which this games canvas will be injected. Either a DOM ID (string) or the element itself.
`state`	object	<optional>	null	The default state object. A object consisting of Phaser.State functions (preload, create, update, render) or null.
`transparent`	boolean	<optional>	false	Use a transparent canvas background or not.
`antialias`	boolean	<optional>	true	Draw all image textures anti-aliased or not. The default is for smooth textures, but disable if your game features pixel art.
`physicsConfig`	object	<optional>	null	A physics configuration object to pass to the Physics world on creation.

Internal:

This member is internal (protected) and may be modified or removed in the future.

Source - core/Game.js, line 520

destroy()

Nukes the entire game from orbit.

Calls destroy on Game.state, Game.sound, Game.scale, Game.stage, Game.input, Game.physics and Game.plugins.

Then sets all of those local handlers to null, destroys the renderer, removes the canvas from the DOM and resets the PIXI default renderer.

Source - core/Game.js, line 1005

disableStep()

Disables core game loop stepping.

Source - core/Game.js, line 980

enableStep()

Enable core game loop stepping. When enabled you must call game.step() directly (perhaps via a DOM button?) Calling step will advance the game loop by one frame. This is extremely useful for hard to track down errors!

Source - core/Game.js, line 966

step()

When stepping is enabled you must call this function directly (perhaps via a DOM button?) to advance the game loop by one frame. This is extremely useful to hard to track down errors! Use the internal stepCount property to monitor progress.

Internal:

This member is internal (protected) and may be modified or removed in the future.

Source - core/Game.js, line 883

<internal> updateRender(elapsedTime)

Runs the Render cycle. It starts by calling State.preRender. In here you can do any last minute adjustments of display objects as required. It then calls the renderer, which renders the entire display list, starting from the Stage object and working down. It then calls plugin.render on any loaded plugins, in the order in which they were enabled. After this State.render is called. Any rendering that happens here will take place on-top of the display list. Finally plugin.postRender is called on any loaded plugins, in the order in which they were enabled. This method is called automatically by Game.update, you don't need to call it directly. Should you wish to have fine-grained control over when Phaser renders then use the Game.lockRender boolean. Phaser will only render when this boolean is false.

Parameters:

Name	Type	Description
`elapsedTime`	number	The time elapsed since the last update.

Internal:
