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>`.

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

.. _class_TileSetSource_method_get_alternative_tile_id:

.. rst-class:: classref-method

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

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** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords **)** |const|

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.

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

----

.. _class_TileSetSource_method_get_tile_id:

.. rst-class:: classref-method

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

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|

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** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords, :ref:`int<class_int>` alternative_tile **)** |const|

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** **(** :ref:`Vector2i<class_Vector2i>` atlas_coords **)** |const|

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

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
.. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
