/**
 * @classdesc
 * A Tilemap is a container for Tilemap data. This isn't a display object, rather, it holds data
 * about the map and allows you to add tilesets and tilemap layers to it. A map can have one or
 * more tilemap layers, which are the display objects that actually render the tiles.
 *
 * The Tilemap data can be parsed from a Tiled JSON file, a CSV file or a 2D array. Tiled is a free
 * software package specifically for creating tile maps, and is available from:
 * http://www.mapeditor.org
 *
 * As of Phaser 3.50.0 the Tilemap API now supports the following types of map:
 *
 * 1) Orthogonal
 * 2) Isometric
 * 3) Hexagonal
 * 4) Staggered
 *
 * Prior to this release, only orthogonal maps were supported.
 *
 * Another large change in 3.50 was the consolidation of Tilemap Layers. Previously, you created
 * either a Static or Dynamic Tilemap Layer. However, as of 3.50 the features of both have been
 * merged and the API simplified, so now there is just the single `TilemapLayer` class.
 *
 * A Tilemap has handy methods for getting and manipulating the tiles within a layer, allowing
 * you to build or modify the tilemap data at runtime.
 *
 * Note that all Tilemaps use a base tile size to calculate dimensions from, but that a
 * TilemapLayer may have its own unique tile size that overrides this.
 *
 * As of Phaser 3.21.0, if your tilemap includes layer groups (a feature of Tiled 1.2.0+) these
 * will be traversed and the following properties will impact children:
 *
 * - Opacity (blended with parent) and visibility (parent overrides child)
 * - Vertical and horizontal offset
 *
 * The grouping hierarchy is not preserved and all layers will be flattened into a single array.
 *
 * Group layers are parsed during Tilemap construction but are discarded after parsing so dynamic
 * layers will NOT continue to be affected by a parent.
 *
 * To avoid duplicate layer names, a layer that is a child of a group layer will have its parent
 * group name prepended with a '/'.  For example, consider a group called 'ParentGroup' with a
 * child called 'Layer 1'. In the Tilemap object, 'Layer 1' will have the name
 * 'ParentGroup/Layer 1'.

    /**
     * This method will iterate through all of the objects defined in a Tiled Object Layer and then
     * convert the matching results into Phaser Game Objects (by default, Sprites)
     *
     * Objects are matched on one of 4 criteria: The Object ID, the Object GID, the Object Name, or the Object Type.
     *
     * Within Tiled, Object IDs are unique per Object. Object GIDs, however, are shared by all objects
     * using the same image. Finally, Object Names and Types are strings and the same name can be used on multiple
     * Objects in Tiled, they do not have to be unique; Names are specific to Objects while Types can be inherited
     * from Object GIDs using the same image.
     *
     * You set the configuration parameter accordingly, based on which type of criteria you wish
     * to match against. For example, to convert all items on an Object Layer with a `gid` of 26:
     *
     * ```javascript
     * createFromObjects(layerName, {
     *   gid: 26
     * });
     * ```
     *
     * Or, to convert objects with the name 'bonus':
     *
     * ```javascript
     * createFromObjects(layerName, {
     *   name: 'bonus'
     * });
     * ```
     *
     * Or, to convert an object with a specific id:
     *
     * ```javascript
     * createFromObjects(layerName, {
     *   id: 9
     * });
     * ```
     *
     * You should only specify either `id`, `gid`, `name`, `type`, or none of them. Do not add more than
     * one criteria to your config. If you do not specify any criteria, then _all_ objects in the
     * Object Layer will be converted.
     *
     * By default this method will convert objects into `Sprite` instances, but you can override
     * this by providing your own class type:
     *
     * ```javascript
     * createFromObjects(layerName, {
     *   gid: 26,
     *   classType: Coin
     * });
     * ```
     *
     * This will convert all Objects with a gid of 26 into your custom `Coin` class. You can pass
     * any class type here, but it _must_ extend `Phaser.GameObjects.GameObject` as its base class.
     * Your class will always be passed 1 parameter: `scene`, which is a reference to either the Scene
     * specified in the config object or, if not given, the Scene to which this Tilemap belongs. The
     * class must have {@link Phaser.GameObjects.Components.Transform#setPosition} and
     * {@link Phaser.GameObjects.Components.Texture#setTexture} methods.
     *
     * All properties from object are copied into the Game Object, so you can use this as an easy
     * way to configure properties from within the map editor. For example giving an object a
     * property of `alpha: 0.5` in Tiled will be reflected in the Game Object that is created.
     *
     * Custom object properties that do not exist as a Game Object property are set in the
     * Game Objects {@link Phaser.GameObjects.GameObject#data data store}.
     *
     * Objects that are based on tiles (tilemap objects that are defined using the `gid` property) can be considered "hierarchical" by passing the third parameter `useTileset` true.
     * Data such as texture, frame (assuming you've matched tileset and spritesheet geometries),
     * `type` and `properties` will use the tileset information first and then override it with data set at the object level.
     * For instance, a tileset which includes
     * `[... a tileset of 16 elements...], [...ids 0, 1, and 2...], {id: 3, type: 'treadmill', speed:4}`
     * and an object layer which includes
     * `{id: 7, gid: 19, speed:5, rotation:90}`
     * will be interpreted as though it were
     * `{id: 7, gid:19, speed:5, rotation:90, type:'treadmill', texture:..., frame:3}`.
     * You can then suppress this behavior by setting the boolean `ignoreTileset` for each `config` that should ignore
     * object gid tilesets.
     *
     * You can set a `container` property in the config. If given, the class will be added to
     * the Container instance instead of the Scene.
     * You can set named texture-`key` and texture-`frame` properties, which will be set on the resultant object.
     *
     * Finally, you can provide an array of config objects, to convert multiple types of object in
     * a single call:
     *
     * ```javascript
     * createFromObjects(layerName, [
     *   {
     *     gid: 26,
     *     classType: Coin
     *   },
     *   {
     *     id: 9,
     *     classType: BossMonster
     *   },
     *   {
     *     name: 'lava',
     *     classType: LavaTile
     *   },
     *   {
     *     type: 'endzone',
     *     classType: Phaser.GameObjects.Zone
     *   }
     * ]);
     * ```
     *
     * The signature of this method changed significantly in v3.60.0. Prior to this, it did not take config objects.
