/**
2014-03-14 06:36:05 +00:00
* Creates a new Phaser.Tilemap object. The map can either be populated with data from a Tiled JSON file or from a CSV file.
* To do this pass the Cache key as the first parameter. When using Tiled data you need only provide the key.
* When using CSV data you must provide the key and the tileWidth and tileHeight parameters.
* If creating a blank tilemap to be populated later, you can either specify no parameters at all and then use `Tilemap.create` or pass the map and tile dimensions here.
* 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 it.
* A Tile map is rendered to the display using a TilemapLayer. It is not added to the display list directly itself.
2013-11-28 15:57:09 +00:00
* A map may have multiple layers. You can perform operations on the map data such as copying, pasting, filling and shuffling the tiles around.
*
* @class Phaser.Tilemap
* @constructor
* @param {Phaser.Game} game - Game reference to the currently running game.
2014-03-14 06:36:05 +00:00
* @param {string} [key] - The key of the tilemap data as stored in the Cache. If you're creating a blank map either leave this parameter out or pass `null`.
* @param {number} [tileWidth=32] - The pixel width of a single map tile. If using CSV data you must specify this. Not required if using Tiled map data.
* @param {number} [tileHeight=32] - The pixel height of a single map tile. If using CSV data you must specify this. Not required if using Tiled map data.
* @param {number} [width=10] - The width of the map in tiles. If this map is created from Tiled or CSV data you don't need to specify this.
* @param {number} [height=10] - The height of the map in tiles. If this map is created from Tiled or CSV data you don't need to specify this.
