Schem (sponge) file conversion to blueprint nbt file, and allowing paste / load / saving it for bits and chisels
First you need to install python 3.8+ and nbtlib via pip. go to CMD, and run /pip install nbtlib... or do it yourself. Then you need .schem format file, its not litematic file. It can be obtained in various ways, but I will take one from https://github.com/Pangamma/PixelStacker.
You also need Fabric-Carpet https://github.com/gnembon/fabric-carpet to import nbt file, or manage, or set in world.
If you're ready, then run something like this:
#a = Schem(nbtlib.load('mumeibig.schem')) #a.saveAll('birb')
It will save all the parts of the file as 'blueprint', so that you can load it from following script.
Sp or Mp, if you run minecraft with carpet, then scripts folder will be generated under worlds/worldname folder. Put blueprint.sc in /scripts/folder. Then you can load it via /script load blueprint.
Zip all the results and put inside /scripts/blueprint.data/, then you can run following script to 'paste':
If you saved as mumei.zip and it starts with birb, then
/script in blueprint run pasteFrom('mumei.zip','birb',[0,128,0])
if you want it to start from [0,128,0], toward +x +y +z.
It will paste blocks automatically : but remember, it can be laggy or there could be some visual glitch, so rejoin minecraft to see it properly.
Yes cute birb with bits and chisels!
It means, you can generate any mini-structures using this!
now there's no zip support, but there's save / load / info command.
/blueprint info
It shows how many bits you need for current 'holding' blueprint.
/blueprint save <name>
It saves current holded blueprint into prefixes + name.
/blueprint load <name>
It loads blueprint from .Overrides current data of blueprint item.
/blueprint loadZip mumei2 a0b0b0
It loads a0b0b0.nbt from mumei2.zip.
