Phaser API Documentation

Description:

Registers a new file type with the global File Types Manager, making it available to all Loader Plugins created after this.

This is usually called from within your Plugin code and is a helpful short-cut for creating new loader file types.

The key is the property that will be injected into the Loader Plugin and used to load the files. For example:

this.plugins.registerFileType('wad', doomWadLoaderCallback);
// later in your preload code:
this.load.wad();

The callback is what is called when the loader tries to load a file matching the given key. It's important to understand that the callback is invoked within the context of the LoaderPlugin. In this context there are several properties / methods available to use:

this.addFile - A method to add the new file to the load queue. this.scene - The Scene that owns the Loader Plugin instance.

See the LoaderPlugin class for more details. Any public property or method listed is available from your callback under this.
