True if all assets in the queue have finished loading.

Source - loader/Loader.js, line 57

Used to map the application mime-types to to the Accept header in XHR requests. If you don't require these mappings, or they cause problems on your server, then remove them from the headers object and the XHR request will not try to use them.

This object can also be used to set the X-Requested-With header to XMLHttpRequest (or any other value you need). To enable this do:

this.load.headers.requestedWith = 'XMLHttpRequest'

before adding anything to the Loader. The XHR loader will then call:

setRequestHeader('X-Requested-With', this.headers['requestedWith'])

Default Value: - {"undefined":"application/xml"}

Source - loader/Loader.js, line 122

True if the Loader is in the process of loading the queue.

The number of concurrent / parallel resources to try and fetch at once.

Many current browsers limit 6 requests per domain; this is slightly conservative.

This should generally be left at the default, but can be set to a higher limit for specific use-cases. Just be careful when setting large values as different browsers could behave differently.

This event is dispatched when a file has either loaded or failed to load.

Any function bound to this will receive the following parameters:

progress, file key, success?, total loaded files, total files

Where progress is a number between 1 and 100 (inclusive) representing the percentage of the load.

Source - loader/Loader.js, line 175

This event is dispatched when a file (or pack) errors as a result of the load request.

For files it will be triggered before onFileComplete. For packs it will be triggered before onPackComplete.

Params: (file key, file)

Source - loader/Loader.js, line 186

This event is dispatched immediately before a file starts loading. It's possible the file may fail (eg. download error, invalid format) after this event is sent.

Params: (progress, file key, file url)

Source - loader/Loader.js, line 162

This event is dispatched when the final file in the load queue has either loaded or failed.

Source - loader/Loader.js, line 141

This event is dispatched when the loading process starts: before the first file has been requested, but after all the initial packs have been loaded.

Source - loader/Loader.js, line 134

This event is dispatched when an asset pack has either loaded or failed to load.

This is called when the asset pack manifest file has loaded and successfully added its contents to the loader queue.

Params: (pack key, success?, total packs loaded, total packs)

Source - loader/Loader.js, line 152

The value of path, if set, is placed before any relative file path given. For example:

load.path = "images/sprites/"; load.image("ball", "ball.png"); load.image("tree", "level1/oaktree.png"); load.image("boom","http://server.com/explode.png");

Would load the ball file from images/sprites/ball.png and the tree from images/sprites/level1/oaktree.png but the file boom would load from the URL given as it's an absolute URL.

Please note that the path is added before the filename but after the baseURL (if set.)

The string must end with a "/".

{Phaser.Loader}

Adds a Texture Atlas file to the current load queue.

To create the Texture Atlas you can use tools such as:

Texture Packer Shoebox

If using Texture Packer we recommend you enable "Trim sprite names". If your atlas software has an option to "rotate" the resulting frames, you must disable it.

You can choose to either load the data externally, by providing a URL to a json file. Or you can pass in a JSON object or String via the atlasData parameter. If you pass a String the data is automatically run through JSON.parse and then immediately added to the Phaser.Cache.

If URLs are provided the files are not loaded immediately after calling this method, but are added to the load queue.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the file via Cache.getImage(key). JSON files are automatically parsed upon load. If you need to control when the JSON is parsed then use Loader.text instead and parse the JSON file as needed.

The URLs can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

If the textureURL isn't specified then the Loader will take the key and create a filename from that. For example if the key is "player" and textureURL is null then the Loader will set the URL to be "player.png". The same is true for the atlasURL. If atlasURL isn't specified and no atlasData has been provided then the Loader will set the atlasURL to be the key. For example if the key is "player" the atlasURL will be set to "player.json".

If you do not desire this action then provide URLs and / or a data object.

Parameters:

Name

Type

Argument

Description

key

atlasURL

string

<optional>

URL of the texture atlas data file. If undefined or null and no atlasData is given, the url will be set to <key>.json, i.e. if key was "alien" then the URL will be "alien.json".

atlasData

object

<optional>

A JSON or XML data object. You don't need this if the data is being loaded from a URL.

format

number

<optional>

The format of the data. Can be Phaser.Loader.TEXTURE_ATLAS_JSON_ARRAY (the default), Phaser.Loader.TEXTURE_ATLAS_JSON_HASH or Phaser.Loader.TEXTURE_ATLAS_XML_STARLING.

Returns:

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the file via Cache.getSound(key).

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

Mobile warning: There are some mobile devices (certain iPad 2 and iPadMini revisions) that cannot play 48000 Hz audio. When they try to play the audio becomes extremely distorted and buzzes, eventually crashing the sound system. The solution is to use a lower encoding rate such as 44100 Hz.

Parameters:

Name

Type

Argument

Default

Description

key

string

Unique asset key of the audio file.

urls

string | Array.<string> | Array.<object>

Either a single string or an array of URIs or pairs of {uri: .., type: ..}. If an array is specified then the first URI (or URI +mime pair) that is device-compatible will be selected. For example: "jump.mp3", ['jump.mp3', 'jump.ogg', 'jump.m4a'], or [{uri: "data:<opus_resource>", type: 'opus'}, 'fallback.mp3']. BLOB and DATA URIs can be used but only support automatic detection when used in the pair form; otherwise the format must be manually checked before adding the resource.

autoDecode

boolean

<optional>

true

When using Web Audio the audio files can either be decoded at load time or run-time. Audio files can't be played until they are decoded and, if specified, this enables immediate decoding. Decoding is a non-blocking async process, however it consumes huge amounts of CPU time on mobiles especially.

Adds an Image to the current load queue.

The file is not loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.

Phaser can load all common image types: png, jpg, gif and any other format the browser can natively handle.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the image via Cache.getImage(key)

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

If the URL isn't specified the Loader will take the key and create a filename from that. For example if the key is "alien" and no URL is given then the Loader will set the URL to be "alien.png". It will always add .png as the extension. If you do not desire this action then provide a URL.

This method also supports passing in a texture object as the url argument. This allows you to load compressed textures into Phaser. You can also use Loader.texture to do this.

Compressed Textures are a WebGL only feature, and require 3rd party tools to create. Available tools include Texture Packer, PVRTexTool, DirectX Texture Tool and Mali Texture Compression Tool.

Supported texture compression formats are: PVRTC, S3TC and ETC1. Supported file formats are: PVR, DDS, KTX and PKM.

The formats that support all 3 compression algorithms are PVR and KTX. PKM only supports ETC1, and DDS only S3TC for now.

The texture path object looks like this:

load.image('factory', {    etc1: 'assets/factory_etc1.pkm',
    s3tc: 'assets/factory_dxt1.pvr',
    pvrtc: 'assets/factory_pvrtc.pvr',
    truecolor: 'assets/factory.png'
});

The truecolor property points to a standard PNG file, that will be used if none of the compressed formats are supported by the browser / GPU.

Parameters:

Name

Type

Argument

Default

Description

key

string

Unique asset key of this image file.

url

string | object

<optional>

URL of an image file. If undefined or null the url will be set to <key>.png, i.e. if key was "alien" then the URL will be "alien.png". Can also be a texture data object.

overwrite

boolean

<optional>

false

If an unloaded file with a matching key already exists in the queue, this entry will overwrite it.

Adds an array of images to the current load queue.

It works by passing each element of the array to the Loader.image method.

The files are not loaded immediately after calling this method. The files are added to the queue ready to be loaded when the loader starts.

Phaser can load all common image types: png, jpg, gif and any other format the browser can natively handle.

The keys must be unique Strings. They are used to add the files to the Phaser.Cache upon successful load.

Retrieve the images via Cache.getImage(key)

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

If the URL isn't specified the Loader will take the key and create a filename from that. For example if the key is "alien" and no URL is given then the Loader will set the URL to be "alien.png". It will always add .png as the extension. If you do not desire this action then provide a URL.

Parameters:

Name

Type

Argument

Description

keys

array

An array of unique asset keys of the image files.

urls

array

<optional>

Optional array of URLs. If undefined or null the url will be set to <key>.png, i.e. if key was "alien" then the URL will be "alien.png". If provided the URLs array length must match the keys array length.

Returns:

Phaser.Loader-

Add a JSON resource pack ('packfile') to the Loader.

A packfile is a JSON file that contains a list of assets to the be loaded. Please see the example 'loader/asset pack' in the Phaser Examples repository.

Packs are always put before the first non-pack file that is not loaded / loading.

This means that all packs added before any loading has started are added to the front of the file queue, in the order added.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

The URL of the packfile can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

Parameters:

Adds a Sprite Sheet to the current load queue.

The file is not loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.

To clarify the terminology that Phaser uses: A Sprite Sheet is an image containing frames, usually of an animation, that are all equal dimensions and often in sequence. For example if the frame size is 32x32 then every frame in the sprite sheet will be that size. Sometimes (outside of Phaser) the term "sprite sheet" is used to refer to a texture atlas. A Texture Atlas works by packing together images as best it can, using whatever frame sizes it likes, often with cropping and trimming the frames in the process. Software such as Texture Packer, Flash CC or Shoebox all generate texture atlases, not sprite sheets. If you've got an atlas then use Loader.atlas instead.

The key must be a unique String. It is used to add the image to the Phaser.Cache upon successful load.

Retrieve the file via Cache.getImage(key). Sprite sheets, being image based, live in the same Cache as all other Images.

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

If the URL isn't specified the Loader will take the key and create a filename from that. For example if the key is "alien" and no URL is given then the Loader will set the URL to be "alien.png". It will always add .png as the extension. If you do not desire this action then provide a URL.

Parameters:

Name

Type

Argument

Default

Description

key

string

Unique asset key of the sheet file.

url

string

URL of the sprite sheet file. If undefined or null the url will be set to <key>.png, i.e. if key was "alien" then the URL will be "alien.png".

frameWidth

number

Width in pixels of a single frame in the sprite sheet.

frameHeight

number

Height in pixels of a single frame in the sprite sheet.

frameMax

number

<optional>

-1

How many frames in this sprite sheet. If not specified it will divide the whole image into frames.

margin

<optional>

0

If the frames have been drawn with a margin, specify the amount here.

spacing

number

<optional>

0

If the frames have been drawn with spacing between them, specify the amount here.

Adds a Compressed Texture Image to the current load queue.

Compressed Textures are a WebGL only feature, and require 3rd party tools to create. Available tools include Texture Packer, PVRTexTool, DirectX Texture Tool and Mali Texture Compression Tool.

Supported texture compression formats are: PVRTC, S3TC and ETC1. Supported file formats are: PVR, DDS, KTX and PKM.

The formats that support all 3 compression algorithms are PVR and KTX. PKM only supports ETC1, and DDS only S3TC for now.

The texture path object looks like this:

load.texture('factory', {    etc1: 'assets/factory_etc1.pkm',
    s3tc: 'assets/factory_dxt1.pvr',
    pvrtc: 'assets/factory_pvrtc.pvr',
    truecolor: 'assets/factory.png'
});

The truecolor property points to a standard PNG file, that will be used if none of the compressed formats are supported by the browser / GPU.

The file is not loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the image via Cache.getImage(key)

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

Adds a Tile Map data file to the current load queue.

Phaser can load data in two different formats: CSV and Tiled JSON.

Tiled is a free software package, specifically for creating tilemaps, and is available from http://www.mapeditor.org

You can choose to either load the data externally, by providing a URL to a json file. Or you can pass in a JSON object or String via the data parameter. If you pass a String the data is automatically run through JSON.parse and then immediately added to the Phaser.Cache.

If a URL is provided the file is not loaded immediately after calling this method, but is added to the load queue.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the file via Cache.getTilemapData(key). JSON files are automatically parsed upon load. If you need to control when the JSON is parsed then use Loader.text instead and parse the text file as needed.

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

If the URL isn't specified and no data is given then the Loader will take the key and create a filename from that. For example if the key is "level1" and no URL or data is given then the Loader will set the URL to be "level1.json". If you set the format to be Tilemap.CSV it will set the URL to be "level1.csv" instead.

If you do not desire this action then provide a URL or data object.

Parameters:

{Phaser.Loader}

Adds a video file to the current load queue.

The file is not loaded immediately after calling this method. The file is added to the queue ready to be loaded when the loader starts.

The key must be a unique String. It is used to add the file to the Phaser.Cache upon successful load.

Retrieve the file via Cache.getVideo(key).

The URL can be relative or absolute. If the URL is relative the Loader.baseURL and Loader.path values will be prepended to it.

You don't need to preload a video in order to play it in your game. See Video.createVideoFromURL for details.

Parameters:

Name

Type

Argument

Default

Description

key

string

Unique asset key of the video file.

urls

string | Array.<string> | Array.<object>

Either a single string or an array of URIs or pairs of {uri: .., type: ..}. If an array is specified then the first URI (or URI +mime pair) that is device-compatible will be selected. For example: "boom.mp4", ['boom.mp4', 'boom.ogg', 'boom.webm'], or [{uri: "data:<opus_resource>", type: 'opus'}, 'fallback.mp4']. BLOB and DATA URIs can be used but only support automatic detection when used in the pair form; otherwise the format must be manually checked before adding the resource.

loadEvent

string

<optional>

'canplaythrough'

This sets the Video source event to listen for before the load is considered complete. 'canplaythrough' implies the video has downloaded enough, and bandwidth is high enough that it can be played to completion. 'canplay' implies the video has downloaded enough to start playing, but not necessarily to finish. 'loadeddata' just makes sure that the video meta data and first frame have downloaded. Phaser uses this value automatically if the browser is detected as being Firefox and no loadEvent is given, otherwise it defaults to canplaythrough.

asBlob

boolean

<optional>

false

Video files can either be loaded via the creation of a video element which has its src property set. Or they can be loaded via xhr, stored as binary data in memory and then converted to a Blob. This isn't supported in IE9 or Android 2. If you need to have the same video playing at different times across multiple Sprites then you need to load it as a Blob.

Returns:

Phaser.Loader-
