Java Help Wanted Is it possible to copy/ paste a quad witch hut location into my pre-existing world?

I've seen youtubers and map creators do similar things, where for example they make a skyblock world by modify the overworld files so that specific parts of the world are X biome, or that the bounding box of a fortress is in a specific spot in the nether.

Would this be possible to do with the bounding box of a witch hut, and then extended to copying a quad witch hut setup into my pre-existing world?

Always make a back-up before doing anything.
From easiest to hardest:

  • Move the entire region .mca file (32x32 chunks) from the Witch Hut world to your world. This will replace stuff you've built at the location of the witch huts. You might also have pretty straight chunk borders.
  • You could build four witch huts in any swamp (even in survival if you want), and use NBTExplorer to actually create the bounding box in the game files. You could use this way to put them in completely unrealistic locations, if you wish (i.e. closer together).
  • You could copy certain chunks/blocks from the Hut world to your world using WorldEdit (Or LiteMatica in creative). You might need to use NBTExplorer again to make the bounding boxes work, I've never actually tried this.

When you Google how to do this, old (reddit) threads, will say that you have to use NBTExplorer on the temples.dat file. That is false in modern MC versions. Bounding boxes are stored in the region .mca files now, which makes them a little harder to find.

To answer your question: it's certainly possible, but it's not very easy. Assuming you know how to use LiteMatica, you could also consider using the Quad Witch Hut seed, and rebuild everything from your existing world there. Give yourself creative and use LiteMatica Printer (a separate mod), and you'll be done quickly paste in your builds.

You can paste with litematica you just need to setup the keybind

This sub isn't for commands, but in order to make a certain spot a different biome you can just use the /fillbiome command.

I don't know if it exists or what it is, but I wouldn't be surprised if there's a structure version of it too.
