Work in progress!
I am trying to replicate the OpenTTD map system in Godot 4.
To get this working I need each height layer to be shifted some pixels up. As the normal tile map cannot work with shifted layers, I am trying to build a new tile map, which leverages multiple normal tile maps, one for each layer.
I am not sure yet, if / how this tile map could be used in real projects. For now think of it as a tech-experiment.
A small, simple noise generator (Diamond Square) is included to generate example maps. It will regenerate on each run.
It requires the map size to be 2^n.
