Hi to all, I need to add a TileSet background, but not a statically one, but one able to scroll just as the TileSet done.
I solved using 2 different TileMap/s, one for the Background and one for the Foreground!
You need a tileset for the background? I think you can just set the z_index of the tileset to a negative number, and then it should be drawn behind all of the other Node2D-based nodes, while still functioning like a normal tileset. You may also need to disable collision though, unless you want your entities to collide with the background, but there is probably a way to do that as well.
I wonder. Might the parallax background be of interest perhaps?
