<brief_description>
Exposes a set of scenes as tiles for a [TileSet] resource.
</brief_description>
<description>
When placed on a [TileMapLayer], tiles from [TileSetScenesCollectionSource] will automatically instantiate an associated scene at the cell's position in the TileMapLayer.
Scenes are instantiated as children of the [TileMapLayer] after it enters the tree, at the end of the frame (their creation is deferred). If you add/remove a scene tile in the [TileMapLayer] that is already inside the tree, the [TileMapLayer] will automatically instantiate/free the scene accordingly.
[b]Note:[/b] Scene tiles all occupy one tile slot and instead use alternate tile ID to identify scene index. [method TileSetSource.get_tiles_count] will always return [code]1[/code]. Use [method get_scene_tiles_count] to get a number of scenes in a [TileSetScenesCollectionSource].
Use this code if you want to find the scene path at a given tile in [TileMapLayer]:

var source_id = tile_map_layer.get_cell_source_id(Vector2i(x, y))
if source_id > -1:

if scene_source is TileSetScenesCollectionSource:
var alt_id = tile_map_layer.get_cell_alternative_tile(Vector2i(x, y))
# The assigned PackedScene.
var scene = scene_source.get_scene_tile_scene(alt_id)

// The assigned PackedScene.

<method name="create_scene_tile">
<return type="int" />
<param index="0" name="packed_scene" type="PackedScene" />
<param index="1" name="id_override" type="int" default="-1" />
<description>
Creates a scene-based tile out of the given scene.
Returns a newly generated unique ID.
</description>
</method>
<method name="get_next_scene_tile_id" qualifiers="const">
<return type="int" />
<description>
Returns the scene ID a following call to [method create_scene_tile] would return.
</description>
</method>
<method name="get_scene_tile_display_placeholder" qualifiers="const">
<return type="bool" />
<param index="0" name="id" type="int" />
<description>
Returns whether the scene tile with [param id] displays a placeholder in the editor.
</description>
</method>
<method name="get_scene_tile_id">
<return type="int" />
<param index="0" name="index" type="int" />
<description>
Returns the scene tile ID of the scene tile at [param index].
</description>
</method>
<method name="get_scene_tile_scene" qualifiers="const">
<return type="PackedScene" />
<param index="0" name="id" type="int" />
<description>
Returns the [PackedScene] resource of scene tile with [param id].
</description>
</method>
<method name="get_scene_tiles_count">
<return type="int" />
<description>
Returns the number or scene tiles this TileSet source has.
</description>
</method>
<method name="has_scene_tile_id">
<return type="bool" />
<param index="0" name="id" type="int" />
<description>
Returns whether this TileSet source has a scene tile with [param id].
</description>
</method>
<method name="remove_scene_tile">
<return type="void" />
<param index="0" name="id" type="int" />
<description>
Remove the scene tile with [param id].
</description>
</method>
<method name="set_scene_tile_display_placeholder">
<return type="void" />
<param index="0" name="id" type="int" />
<param index="1" name="display_placeholder" type="bool" />
<description>
Sets whether or not the scene tile with [param id] should display a placeholder in the editor. This might be useful for scenes that are not visible.
</description>
</method>
<method name="set_scene_tile_id">
<return type="void" />
<param index="0" name="id" type="int" />
<param index="1" name="new_id" type="int" />
<description>
Changes a scene tile's ID from [param id] to [param new_id]. This will fail if there is already a tile with an ID equal to [param new_id].
</description>
</method>
<method name="set_scene_tile_scene">
<return type="void" />
<param index="0" name="id" type="int" />
<param index="1" name="packed_scene" type="PackedScene" />
<description>
Assigns a [PackedScene] resource to the scene tile with [param id]. This will fail if the scene does not extend [CanvasItem], as positioning properties are needed to place the scene on the [TileMapLayer].
