Can I move buildings from a snowy super-flat map into a plains super flat map? [closed]

Can I move all my buildings in a world that is a snowy super-flat, into a plain super flat?

I assume I would need to know where my building files are or, the files that contain the biome so I can just change that.

Is this possible?

Solution 1:

The files are in %AppData%\Roaming\.minecraft\saves\[world name]\region but it won't help you, because the game doesn't distinguish what is a block of the originally generated snowed over grass, and what is a block of your house you had placed. These files contain 512x512 blocks (x256 height) areas of the world each, and they don't distinguish what was naturally generated and what was placed by the player, they also contain the biome information, so even if you 'transplant' the area with your buildings to your new world, you'll have a 512x512 area with snowfall where everywhere else it's raining.

If the structures aren't very big and there's not a lot of them, I'd recommend using the Structure Block. One block can save a 32x32x32 volume you can then restore elsewhere using Structure Block in 'load' mode. There are techniques of chaining more structure blocks together (essentially, save the prior structure block within the next one), so a build of 100x100 blocks or so is relatively doable. If you need more, you'll need tools like WorldEdit - and it would probably be easier to change the biome of your world with it.
