	</brief_description>
	<description>
		Node for 2D tile-based maps. Tilemaps use a [TileSet] which contain a list of tiles which are used to create grid-based maps. A TileMap may have several layers, layouting tiles on top of each other.

			<description>
				Sets the tile indentifiers for the cell on layer [code]layer[/code] at coordinates [code]coords[/code]. Each tile of the [TileSet] is identified using three parts:
				- The source indentifier [code]source_id[/code] identifies a [TileSetSource] identifier. See [method TileSet.set_source_id],
				- The atlas coordinates identifier [code]atlas_coords[/code] identifies a tile coordinates in the atlas (if the source is a [TileSetAtlasSource]. For [TileSetScenesCollectionSource] it should be 0),
				- The alternative tile identifier [code]alternative_tile[/code] identifies a tile alternative the source is a [TileSetAtlasSource], and the scene for a [TileSetScenesCollectionSource].

		<method name="set_layer_enabled">
			<return type="void" />
			<argument index="0" name="layer" type="int" />
			<argument index="1" name="enabled" type="bool" />
			<description>
				Enables or disables the layer [code]layer[/code]. A disabled layer is not processed at all (no rendering, no physics, etc...).
			</description>

		<method name="set_layer_name">
			<return type="void" />
			<argument index="0" name="layer" type="int" />
			<argument index="1" name="name" type="String" />
			<description>

		<method name="set_layer_y_sort_enabled">
			<return type="void" />
			<argument index="0" name="layer" type="int" />
			<argument index="1" name="y_sort_enabled" type="bool" />
			<description>
				Enables or disables a layer's Y-sorting. If a layer is Y-sorted, the layer will behave as a CanvasItem node where each of its tile gets Y-sorted.
				Y-sorted layers should usually be on different Z-index values than not Y-sorted layers, otherwise, each of those layer will be Y-sorted as whole with the Y-sorted one. This is usually an undesired behvaior.

		</method>
		<method name="set_layer_y_sort_origin">
			<return type="void" />
			<argument index="0" name="layer" type="int" />
			<argument index="1" name="y_sort_origin" type="int" />
			<description>
				Sets a layer's Y-sort origin value. This Y-sort origin value is added to each tile's Y-sort origin value.
				This allows, for example, to fake a different height level on each layer. This can be useful for top-down view games.
			</description>
		</method>
		<method name="set_layer_z_index">
			<return type="void" />
			<argument index="0" name="layer" type="int" />
			<argument index="1" name="z_index" type="int" />
			<description>
				Sets a layers Z-index value. This Z-index is added to each tile's Z-index value.
