Are these kind of projects actually build manually inside of minecraft block by block or is there some verilog/vhdl to minecraft-level compiler toolchains used?
They did not manually place hundreds of millions of blocks <:
It’s been awhile since I’ve played Minecraft, but when I built large redstone projects before, I built out each circuit manually and then used mods to copy/paste it within the game.
And nowadays you can use Axiom, which is a much better experience than WorldEdit (WE still has its uses though!)
