如何读取 Minecraft .mca 文件以便在 python 中提取单个块？

Question

我找不到一种可以在 python 中使用的方式读取 Minecraft 世界文件的方法

我浏览了互联网，但找不到任何教程，只有几个库声称他们可以做到这一点，但从未真正起作用

from nbt import *
nbtfile = nbt.NBTFile("r.0.0.mca",'rb')

我预计这会起作用，但我收到了有关文件未压缩或类似内容的错误

完整错误：

Traceback (most recent call last):
  File "C:\Users\rober\Desktop\MinePy\MinecraftWorldReader.py", line 2, in <module>
    nbtfile = nbt.NBTFile("r.0.0.mca",'rb')

使用 anvil 解析器。（安装pip install anvil-parser）

import anvil

region = anvil.Region.from_file('r.0.0.mca')

# You can also provide the region file name instead of the object
chunk = anvil.Chunk.from_region(region, 0, 0)

# If `section` is not provided, will get it from the y coords
# and assume it's global
block = chunk.get_block(0, 0, 0)

print(block) # <Block(minecraft:air)>
print(block.id) # air
print(block.properties) # {}
