    //  The second is a URL to the JSON file the map data is stored in. This is actually optional, you can pass the JSON object as the 3rd
    //  parameter if you already have it loaded (maybe via a 3rd party source or pre-generated). In which case pass 'null' as the URL and
    //  the JSON object as the 3rd parameter.

    //  The final one tells Phaser the foramt of the map data, in this case it's a JSON file exported from the Tiled map editor.
