How Y sort works for layers

Hi, I’m trying to programmatically create an isometric scene. When I paint the scene I get this:
Painting the scene

Seems that layers sort y with themselves but not with the rest of the tilemap.

This is the code:

	public override void _Ready()

	_packedScene = ResourceLoader.Load<PackedScene>("res://data/TerrainTileMap.tscn");

	var tm1 = _packedScene.Instantiate<TileMap>();
	tm1.SetLayerYSortEnabled(0, true);
	tm1.SetCell(0, new Vector2i(5,5), 0, new Vector2i(1,0), 0);
	tm1.SetCell(0, new Vector2i(5,6), 0, new Vector2i(1,0), 0);
	tm1.SetCell(0, new Vector2i(5,7), 0, new Vector2i(1,0), 0);
	for (var i = 8; i < 20; i++)
		tm1.SetCell(0, new Vector2i(5,i), 0, new Vector2i(1,0), 0);	
	tm1.SetLayerYSortEnabled(1, true);
	tm1.SetLayerModulate(1, Colors.Aqua);
	tm1.SetCell(1, new Vector2i(5,11), 0, new Vector2i(1,0), 0);

	AddChild(tm1); }

So how to use Y sorting using the whole tilemap? Or it’s simply that I’m not using layers properly?

Hi, I just want to confirm: You want all elements in the TileMap on any layer be y_sorted with each other?

E.g. if I have a tile with y-value 0 and one with 2 on layer 1 and a tile with y-value 1 on layer 2 then it should be between both of them?

From the documentation TileMap — Godot Engine (latest) documentation in English

I understand that the y-sort should only work on your current layer, not all of them.
Therefore I think that you would need to move all objects you want to y-sort into one layer.

Well, to give some context, what I want to do is to highlight some tiles by coloring them (for UI/UX purposes). As you can not modulate a single tile, I decided to simply paint a second layer with the highlighted tiles. But the Y-sort of the layer only seems to work on the layer and not in the whole tilemap. If there is an alternative method to color a single tile, that can be a solution for me.

Are the tilemaps a child of YSort node?

Ysort is not a node in Godot 4.

y-sort is different in godot 4 than godot 3
