* Phaser - http://phaser.io
|
|
*
|
|
* v2.3.0 "Tarabon" - Built: Wed Mar 25 2015 16:17:23
|
|
*
|
|
* By Richard Davey http://www.photonstorm.com @photonstorm
|
|
*
|
|
* Phaser is a fun, free and fast 2D game framework for making HTML5 games
|
|
* for desktop and mobile web browsers, supporting Canvas and WebGL rendering.
|
|
*
|
|
* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com @Doormat23
|
|
* Phaser uses p2.js for full-body physics, created by Stefan Hedman https://github.com/schteppe/p2.js @schteppe
|
|
* Phaser contains a port of N+ Physics, converted by Richard Davey, original by http://www.metanetsoftware.com
|
|
*
|
|
* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from which both Phaser
|
|
* and my love of framework development originate.

* A RenderTexture is a special texture that allows any Pixi display object to be rendered to it.
|
|
*
|
|
* __Hint__: All DisplayObjects (i.e. Sprites) that render to a RenderTexture should be preloaded otherwise black rectangles will be drawn instead.
|
|
*
|
|
* A RenderTexture takes a snapshot of any Display Object given to its render method. The position and rotation of the given Display Objects is ignored. For example:
|
|
*
|
|
* var renderTexture = new PIXI.RenderTexture(800, 600);
|
|
* var sprite = PIXI.Sprite.fromImage("spinObj_01.png");
|
|
* sprite.position.x = 800/2;
|
|
* sprite.position.y = 600/2;
|
|
* sprite.anchor.x = 0.5;
|
|
* sprite.anchor.y = 0.5;
|
|
* renderTexture.render(sprite);
|
|
*
|
|
* The Sprite in this case will be rendered to a position of 0,0. To render this sprite at its actual position a DisplayObjectContainer should be used:
|
|
*
|
|
* var doc = new PIXI.DisplayObjectContainer();
|
|
* doc.addChild(sprite);
|
|
* renderTexture.render(doc); // Renders to center of renderTexture

|
|
* The ScaleManager object handles the the scaling, resizing, and alignment of the
|
|
* Game size and the game Display canvas.
|
|
*
|
|
* The Game size is the logical size of the game; the Display canvas has size as an HTML element.
|
|
*
|
|
* The calculations of these are heavily influenced by the bounding Parent size which is the computed
|
|
* dimensions of the Display canvas's Parent container/element - the _effective CSS rules of the
|
|
* canvas's Parent element play an important role_ in the operation of the ScaleManager.
|
|
*
|
|
* The Display canvas - or Game size, depending {@link #scaleMode} - is updated to best utilize the Parent size.
|
|
* When in Fullscreen mode or with {@link #parentIsWindow} the Parent size is that of the visual viewport (see {@link Phaser.ScaleManager#getParentBounds getParentBounds}).
|
|
*
|
|
* Parent and Display canvas containment guidelines:
|
|
*
|
|
* - Style the Parent element (of the game canvas) to control the Parent size and
|
|
* thus the Display canvas's size and layout.
|
|
*
|
|
* - The Parent element's CSS styles should _effectively_ apply maximum (and minimum) bounding behavior.
|
|
*
|
|
* - The Parent element should _not_ apply a padding as this is not accounted for.
|
|
* If a padding is required apply it to the Parent's parent or apply a margin to the Parent.
|
|
* If you need to add a border, margin or any other CSS around your game container, then use a parent element and
|
|
* apply the CSS to this instead, otherwise you'll be constantly resizing the shape of the game container.
|
|
*
|
|
* - The Display canvas layout CSS styles (i.e. margins, size) should not be altered/specified as
|
|
* they may be updated by the ScaleManager.
|
|
*
|
|
* @description
|
|
* Create a new ScaleManager object - this is done automatically by {@link Phaser.Game}

*

* The SpriteBatch class is a really fast version of the DisplayObjectContainer built purely for speed, so use when you need a lot of sprites or particles.
|
|
* It's worth mentioning that by default sprite batches are used through-out the renderer, so you only really need to use a SpriteBatch if you have over
|
|
* 1000 sprites that all share the same texture (or texture atlas). It's also useful if running in Canvas mode and you have a lot of un-rotated or un-scaled
|
|
* Sprites as it skips all of the Canvas setTransform calls, which helps performance, especially on mobile devices.
|
|
*
|
|
* Please note that any Sprite that is part of a SpriteBatch will not have its bounds updated, so will fail checks such as outOfBounds.

* BitmapText objects work by taking a texture file and an XML file that describes the font structure.

* match the font structure.
|
|
*
|
|
* BitmapText objects are less flexible than Text objects, in that they have less features such as shadows, fills and the ability
|
|
* to use Web Fonts, however you trade this flexibility for rendering speed. You can also create visually compelling BitmapTexts by
|
|
* processing the font texture in an image editor, applying fills and any other effects required.

* To create a BitmapText you can use:
