Node for 2D tile-based maps.

.. rst-class:: classref-introduction-group

Description
-----------

Node for 2D tile-based maps. Tilemaps use a :ref:`TileSet<class_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.

Method Descriptions
-------------------

.. _class_TileMap_method__tile_data_runtime_update:

.. rst-class:: classref-method

void **_tile_data_runtime_update** **(** :ref:`int<class_int>` layer, :ref:`Vector2i<class_Vector2i>` coords, :ref:`TileData<class_TileData>` tile_data **)** |virtual|

Called with a TileData object about to be used internally by the TileMap, allowing its modification at runtime.

This method is only called if :ref:`_use_tile_data_runtime_update<class_TileMap_method__use_tile_data_runtime_update>` is implemented and returns ``true`` for the given tile ``coords`` and ``layer``.

\ **Warning:** The ``tile_data`` object's sub-resources are the same as the one in the TileSet. Modifying them might impact the whole TileSet. Instead, make sure to duplicate those resources.

\ **Note:** If the properties of ``tile_data`` object should change over time, use :ref:`force_update<class_TileMap_method_force_update>` to trigger a TileMap update.

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method__use_tile_data_runtime_update:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_use_tile_data_runtime_update** **(** :ref:`int<class_int>` layer, :ref:`Vector2i<class_Vector2i>` coords **)** |virtual|

Should return ``true`` if the tile at coordinates ``coords`` on layer ``layer`` requires a runtime update.

\ **Warning:** Make sure this function only return ``true`` when needed. Any tile processed at runtime without a need for it will imply a significant performance penalty.

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method_add_layer:

.. rst-class:: classref-method

void **add_layer** **(** :ref:`int<class_int>` to_position **)**

Adds a layer at the given position ``to_position`` in the array. If ``to_position`` is negative, the position is counted from the end, with ``-1`` adding the layer at the end of the array.

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method_clear:

.. rst-class:: classref-method

void **clear** **(** **)**

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method_clear_layer:

.. rst-class:: classref-method

void **clear_layer** **(** :ref:`int<class_int>` layer **)**

----

.. _class_TileMap_method_erase_cell:

.. rst-class:: classref-method

void **erase_cell** **(** :ref:`int<class_int>` layer, :ref:`Vector2i<class_Vector2i>` coords **)**

Erases the cell on layer ``layer`` at coordinates ``coords``.

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method_fix_invalid_tiles:

.. rst-class:: classref-method

void **fix_invalid_tiles** **(** **)**

Clears cells that do not exist in the tileset.

.. rst-class:: classref-item-separator

----

.. _class_TileMap_method_force_update:

.. rst-class:: classref-method

void **force_update** **(** :ref:`int<class_int>` layer=-1 **)**

Triggers an update of the TileMap. If ``layer`` is provided, only updates the given layer.

\ **Note:** The TileMap node updates automatically when one of its properties is modified. A manual update is only needed if runtime modifications (implemented in :ref:`_tile_data_runtime_update<class_TileMap_method__tile_data_runtime_update>`) need to be applied.

\ **Warning:** Updating the TileMap is computationally expensive and may impact performance. Try to limit the number of updates and the tiles they impact (by placing frequently updated tiles in a dedicated layer for example).

Returns the tile source ID of the cell on layer ``layer`` at coordinates ``coords``. Returns ``-1`` if the cell does not exist.

If ``use_proxies`` is ``false``, ignores the :ref:`TileSet<class_TileSet>`'s tile proxies, returning the raw alternative identifier. See :ref:`TileSet.map_tile_proxy<class_TileSet_method_map_tile_proxy>`.

Returns a :ref:`Vector2i<class_Vector2i>` array with the positions of all cells containing a tile in the given layer. Tiles may be filtered according to their source (``source_id``), their atlas coordinates (``atlas_coords``) or alternative id (``source_id``).

If a parameter has it's value set to the default one, this parameter is not used to filter a cell. Thus, if all parameters have their respective default value, this method returns the same result as :ref:`get_used_cells<class_TileMap_method_get_used_cells>`.

A cell is considered empty if its source identifier equals -1, its atlas coordinates identifiers is ``Vector2(-1, -1)`` and its alternative identifier is -1.

Returns for the given coordinate ``coords_in_pattern`` in a :ref:`TileMapPattern<class_TileMapPattern>` the corresponding cell coordinates if the pattern was pasted at the ``position_in_tilemap`` coordinates (see :ref:`set_pattern<class_TileMap_method_set_pattern>`).

.. rst-class:: classref-method

:ref:`Vector2<class_Vector2>` **map_to_local** **(** :ref:`Vector2i<class_Vector2i>` map_position **)** |const|

Returns the centered position of a cell in the TileMap's local coordinate space. To convert the returned value into global coordinates, use :ref:`Node2D.to_global<class_Node2D_method_to_global>`. See also :ref:`local_to_map<class_TileMap_method_local_to_map>`.

\ **Note:** This may not correspond to the visual position of the tile, i.e. it ignores the :ref:`TileData.texture_offset<class_TileData_property_texture_offset>` property of individual tiles.

Sets the tile indentifiers for the cell on layer ``layer`` at coordinates ``coords``. Each tile of the :ref:`TileSet<class_TileSet>` is identified using three parts:

- The source identifier ``source_id`` identifies a :ref:`TileSetSource<class_TileSetSource>` identifier. See :ref:`TileSet.set_source_id<class_TileSet_method_set_source_id>`,

- The atlas coordinates identifier ``atlas_coords`` identifies a tile coordinates in the atlas (if the source is a :ref:`TileSetAtlasSource<class_TileSetAtlasSource>`. For :ref:`TileSetScenesCollectionSource<class_TileSetScenesCollectionSource>` it should always be ``Vector2i(0, 0)``),

- The alternative tile identifier ``alternative_tile`` identifies a tile alternative the source is a :ref:`TileSetAtlasSource<class_TileSetAtlasSource>`, and the scene for a :ref:`TileSetScenesCollectionSource<class_TileSetScenesCollectionSource>`.

If ``source_id`` is set to ``-1``, ``atlas_coords`` to ``Vector2i(-1, -1)`` or ``alternative_tile`` to ``-1``, the cell will be erased. An erased cell gets **all** its identifiers automatically set to their respective invalid values, namely ``-1``, ``Vector2i(-1, -1)`` and ``-1``.

Update all the cells in the ``cells`` coordinates array so that they use the given ``terrain`` for the given ``terrain_set``. If an updated cell has the same terrain as one of its neighboring cells, this function tries to join the two. This function might update neighboring tiles if needed to create correct terrain transitions.

If ``ignore_empty_terrains`` is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.

\ **Note:** To work correctly, ``set_cells_terrain_connect`` requires the TileMap's TileSet to have terrains set up with all required terrain combinations. Otherwise, it may produce unexpected results.

Update all the cells in the ``path`` coordinates array so that they use the given ``terrain`` for the given ``terrain_set``. The function will also connect two successive cell in the path with the same terrain. This function might update neighboring tiles if needed to create correct terrain transitions.

If ``ignore_empty_terrains`` is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.

.. _class_TileMap_method_set_layer_enabled:

.. rst-class:: classref-method

void **set_layer_enabled** **(** :ref:`int<class_int>` layer, :ref:`bool<class_bool>` enabled **)**

Enables or disables the layer ``layer``. A disabled layer is not processed at all (no rendering, no physics, etc...).

If ``layer`` is negative, the layers are accessed from the last one.

.. rst-class:: classref-method

void **set_layer_y_sort_enabled** **(** :ref:`int<class_int>` layer, :ref:`bool<class_bool>` y_sort_enabled **)**

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 behavior.

If ``layer`` is negative, the layers are accessed from the last one.

.. rst-class:: classref-method

void **set_layer_y_sort_origin** **(** :ref:`int<class_int>` layer, :ref:`int<class_int>` y_sort_origin **)**

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.

If ``layer`` is negative, the layers are accessed from the last one.
