TileSetSource
=============

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

**Inherited By:** :ref:`TileSetAtlasSource<class_TileSetAtlasSource>`, :ref:`TileSetScenesCollectionSource<class_TileSetScenesCollectionSource>`

Exposes a set of tiles for a :ref:`TileSet<class_TileSet>` resource.

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

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

Exposes a set of tiles for a :ref:`TileSet<class_TileSet>` resource.

Tiles in a source are indexed with two IDs, coordinates ID (of type Vector2i) and an alternative ID (of type int), named according to their use in the :ref:`TileSetAtlasSource<class_TileSetAtlasSource>` class.

Depending on the TileSet source type, those IDs might have restrictions on their values, this is why the base **TileSetSource** class only exposes getters for them.

You can iterate over all tiles exposed by a TileSetSource by first iterating over coordinates IDs using :ref:`get_tiles_count<class_TileSetSource_method_get_tiles_count>` and :ref:`get_tile_id<class_TileSetSource_method_get_tile_id>`, then over alternative IDs using :ref:`get_alternative_tiles_count<class_TileSetSource_method_get_alternative_tiles_count>` and :ref:`get_alternative_tile_id<class_TileSetSource_method_get_alternative_tile_id>`.

\ **Warning:** **TileSetSource** can only be added to one TileSet at the same time. Calling :ref:`TileSet.add_source<class_TileSet_method_add_source>` on a second :ref:`TileSet<class_TileSet>` will remove the source from the first one.

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

.. _class_TileSetSource_method_get_alternative_tile_id:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_alternative_tile_id**\ (\ atlas_coords\: :ref:`Vector2i<class_Vector2i>`, index\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_TileSetSource_method_get_alternative_tile_id>`

Returns the alternative ID for the tile with coordinates ID ``atlas_coords`` at index ``index``.

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

----

.. _class_TileSetSource_method_get_alternative_tiles_count:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_alternative_tiles_count**\ (\ atlas_coords\: :ref:`Vector2i<class_Vector2i>`\ ) |const| :ref:`🔗<class_TileSetSource_method_get_alternative_tiles_count>`

Returns the number of alternatives tiles for the coordinates ID ``atlas_coords``.

For :ref:`TileSetAtlasSource<class_TileSetAtlasSource>`, this always return at least 1, as the base tile with ID 0 is always part of the alternatives list.

Returns -1 if there is not tile at the given coords.

.. _class_TileSetSource_method_get_tile_id:

.. rst-class:: classref-method

:ref:`Vector2i<class_Vector2i>` **get_tile_id**\ (\ index\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_TileSetSource_method_get_tile_id>`

Returns the tile coordinates ID of the tile with index ``index``.

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

----

.. _class_TileSetSource_method_get_tiles_count:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_tiles_count**\ (\ ) |const| :ref:`🔗<class_TileSetSource_method_get_tiles_count>`

Returns how many tiles this atlas source defines (not including alternative tiles).

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

----

.. _class_TileSetSource_method_has_alternative_tile:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has_alternative_tile**\ (\ atlas_coords\: :ref:`Vector2i<class_Vector2i>`, alternative_tile\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_TileSetSource_method_has_alternative_tile>`

Returns if the base tile at coordinates ``atlas_coords`` has an alternative with ID ``alternative_tile``.

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

----

.. _class_TileSetSource_method_has_tile:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has_tile**\ (\ atlas_coords\: :ref:`Vector2i<class_Vector2i>`\ ) |const| :ref:`🔗<class_TileSetSource_method_has_tile>`

Returns if this atlas has a tile with coordinates ID ``atlas_coords``.
