Getting to know atlas tilemaps and autotilemaps

I always wondered, how to make smooth borders of tiles on an autogenerated map. Than I learned about atlas tilemaps and autotiles in Godot.

The system is pretty easy once you learned it. You generate a tilemaps with all possible border tiles and you tell the Godot tilemap, which tile stands for which border (i.e. border left, border top-left). After placing the tiles and calling the autoconnect function in code, Godot will take care of the rest and create the correct borders (like a beach on the end of a water tile).

But also, I am not quite there yet. There are some nitty-gritty parts that still won’t work for me. But again: Huge progress for myself.
