TileSetAtlasSource
==================

**Inherits:** :ref:`TileSetSource<class_TileSetSource>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Exposes a 2D atlas texture as a set of tiles for a :ref:`TileSet<class_TileSet>` resource.

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

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

An atlas is a grid of tiles laid out on a texture. Each tile in the grid must be exposed using :ref:`create_tile<class_TileSetAtlasSource_method_create_tile>`. Those tiles are then indexed using their coordinates in the grid.

Each tile can also have a size in the grid coordinates, making it more or less cells in the atlas.

Alternatives version of a tile can be created using :ref:`create_alternative_tile<class_TileSetAtlasSource_method_create_alternative_tile>`, which are then indexed using an alternative ID. The main tile (the one in the grid), is accessed with an alternative ID equal to 0.

Each tile alternate has a set of properties that is defined by the source's :ref:`TileSet<class_TileSet>` layers. Those properties are stored in a TileData object that can be accessed and modified using :ref:`get_tile_data<class_TileSetAtlasSource_method_get_tile_data>`.

As TileData properties are stored directly in the TileSetAtlasSource resource, their properties might also be set using ``TileSetAtlasSource.set("<coords_x>:<coords_y>/<alternative_id>/<tile_data_property>")``.

- void **set_texture** **(** :ref:`Texture2D<class_Texture2D>` value **)**
- :ref:`Texture2D<class_Texture2D>` **get_texture** **(** **)**

----

.. _class_TileSetAtlasSource_property_use_texture_padding:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **use_texture_padding** = ``true``

Returns a tile's texture region in the atlas texture. For animated tiles, a ``frame`` argument might be provided for the different frames of the animation.

Returns an array of tiles coordinates ID that will be automatically removed when modifying one or several of those properties: ``texture``, ``margins``, ``separation`` or ``texture_region_size``. This can be used to undo changes that would have caused tiles data loss.

Returns whether there is enough room in an atlas to create/modify a tile with the given properties. If ``ignored_tile`` is provided, act as is the given tile was not present in the atlas. This may be used when you want to modify a tile's properties.

.. _class_TileSetAtlasSource_method_has_tiles_outside_texture:

:ref:`bool<class_bool>` **has_tiles_outside_texture** **(** **)** |const|

Checks if the source has any tiles that don't fit the texture area (either partially or completely).

Move the tile and its alternatives at the ``atlas_coords`` coordinates to the ``new_atlas_coords`` coordinates with the ``new_size`` size. This functions will fail if a tile is already present in the given area.

If ``new_atlas_coords`` is ``Vector2i(-1, -1)``, keeps the tile's coordinates. If ``new_size`` is ``Vector2i(-1, -1)``, keeps the tile's size.

To avoid an error, first check if a move is possible using :ref:`has_room_for_tile<class_TileSetAtlasSource_method_has_room_for_tile>`.

void **remove_alternative_tile** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords, :ref:`int<class_int>` alternative_tile **)**

Remove a tile's alternative with alternative ID ``alternative_tile``.

Calling this function with ``alternative_tile`` equals to 0 will fail, as the base tile alternative cannot be removed.

.. _class_TileSetAtlasSource_method_remove_tile:

Remove a tile and its alternative at coordinates ``atlas_coords``.

void **set_alternative_tile_id** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords, :ref:`int<class_int>` alternative_tile, :ref:`int<class_int>` new_id **)**

Change a tile's alternative ID from ``alternative_tile`` to ``new_id``.

Calling this function with ``new_id`` of 0 will fail, as the base tile alternative cannot be moved.

void **set_tile_animation_columns** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords, :ref:`int<class_int>` frame_columns **)**

Sets the number of columns in the animation layout of the tile at coordinates ``atlas_coords``. If set to 0, then the different frames of the animation are laid out as a single horizontal line in the atlas.
