A way to retrieve scenes instanced as a tile on a tilemap

[feelingsonice]

So Godot 4 now supports adding scenes to a TileMap as a tile. It only makes sense to add a way to retrieve the scenes instanced on a specific coordinate, so that the user can use it like an actual scene by calling methods available on it.

This may be feasible already (cc @groud) using a combination of local_to_map() methods and a TileSet method to get a tile data according to its ID. If that's the case, it's a matter of documentation 🙂

Have you got an example of how you would achieve this?

[Calinou]

Sorry, I don't know how to achieve this.

[feelingsonice]

@Calinou could you be so kind to advise a work-around for the time-being?

[AThousandShips]

I'm sorry I assumed you hadn't because you asked someone who said they didn't know how to do it

[AThousandShips]

There isn't a straight forward way to get the actual instanced scenes, but the ability to get the packed scene of a specific tile can be done with some combination of TileMap.get_cell_atlas_coords, and TileSetScenesCollectionSource.get_scene_tile_scene

Direct support for accessing the scenes themselves isn't available, and the instanced scenes are considered internal, they might also be reinstanced if the quadrant is updated, unsure

Interesting. Could we consider adding this in future updates? Feel like it'd be a feature people would like.

Thats what that proposal is for, but there's still the issues raised there to consider for this discussion as well, and I agree with groud about that exposing access to these internal scenes is something that might not be desirable, and see the suggestions for workarounds there
