scripts(key, [url], [extension], [xhrSettings])


Adds an array of Script files to the current load queue.

The difference between this and the ScriptFile file type is that you give an array of scripts to this method, and the scripts are then processed exactly in that order. This allows you to load a bunch of scripts that may have dependencies on each other without worrying about the async nature of traditional script loading.

You can call this method from within your Scene's preload, along with any other files you wish to load:

function preload ()
    this.load.scripts('PostProcess', [

In the code above the script files will all be loaded in parallel but only processed (i.e. invoked) in the exact order given in the array.

The files are not loaded right away. They are added to a queue ready to be loaded either when the loader starts, or if it's already running, when the next free load slot becomes available. This happens automatically if you are calling this from within the Scene's preload method, or a related callback. Because the files are queued it means you cannot use the files immediately after calling this method, but must wait for the files to complete. The typical flow for a Phaser Scene is that you load assets in the Scene's preload method and then when the Scene's create method is called you are guaranteed that all of those assets are ready for use and have been loaded.

The key must be a unique String and not already in-use by another file in the Loader.

Instead of passing arguments you can pass a configuration object, such as:

    key: 'PostProcess',
    url: [

See the documentation for Phaser.Types.Loader.FileTypes.MultiScriptFileConfig for more details.

Once all the files have finished loading they will automatically be converted into a script element via document.createElement('script'). They will have their language set to JavaScript, defer set to false and then the resulting element will be appended to document.head. Any code then in the script will be executed. This is done in the exact order the files are specified in the url array.

The URLs can be relative or absolute. If the URLs are relative the Loader.baseURL and Loader.path values will be prepended to them.

Note: The ability to load this type of file will only be available if the MultiScript File type has been built into Phaser. It is available in the default build but can be excluded from custom builds.
