ArmouredWizard, I've managed to convert my Dungeon Generator over to Godot.
Took me literally all day to get the Corridors code working, and it still needs a lot of tweaking.
And this is just a Map. So much more to turn it into anything useful.Rooms generated as random, non-overlapping, rectangles, then centres joined in turn.
Next: align corridors and trim unneeded ones
