How to access instances of a TileMap Scene Collection?

Question

I’m experimenting with the Scene Collection feature of the TileMapLayer node and want to use it to define enemy spawn points.
My problem is that I can’t find a way to access the instances of the Scene Collection.

I’ve tried using TileData and groups but it doesn’t work. What can I do instead?

@onready var _enemy_spawner_tile_map_layer: TileMapLayer = $EnemySpawnerTileMapLayer

func _ready() -> void:
	for used_cell: Vector2i in _enemy_spawner_tile_map_layer.get_used_cells():
		var tile_data := _enemy_spawner_tile_map_layer.get_cell_tile_data(used_cell) as TileData
		# is never true
		if not tile_data == null:
			breakpoint

func _ready() -> void:
	var enemy_spawn_markers := get_tree().get_nodes_in_group("enemy_spawn_marker")

	# also never true
	if not enemy_spawn_markers.is_empty():
		breakpoint

I assumed that for each tile with defined SceneCollection, that an object of type TileSetScenesCollectionSource is created.
Could you check the Remote tab of when the game is running? Is there a data object inside your SceneTree that could be your TileSetScenesCollectionSource.
If you knew the tile coordinates, you could also get the TileSetSource directly.

As I haven’t worked with the TileMapLayer yet, I could only reference the documentation:

• TileSetScenesCollectionSource — Godot Engine (stable) documentation in English
• TileSetSource — Godot Engine (stable) documentation in English

Checking the remote tab was a great idea! Thanks.
