anvil-parser

A parser for the Minecraft anvil file format. This package was forked from matcool's anvil-parser in order to additionally support minecraft versions 1.18 and above.

Installation

pip install anvil-parser2

Usage

Reading

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) # {}

Making own regions

import anvil
from random import choice

# Create a new region with the `EmptyRegion` class at 0, 0 (in region coords)
region = anvil.EmptyRegion(0, 0)

# Create `Block` objects that are used to set blocks
stone = anvil.Block('minecraft', 'stone')
dirt = anvil.Block('minecraft', 'dirt')

# Make a 16x16x16 cube of either stone or dirt blocks
for y in range(16):
    for z in range(16):
        for x in range(16):
            region.set_block(choice((stone, dirt)), x, y, z)

# Save to a file
region.save('r.0.0.mca')

Todo

things to do before 1.0.0

• Proper documentation
• Biomes
• CI
• More tests
  • Tests for 20w17a+ BlockStates format

Note

Testing done in 1.14.4 - 1.19, should work fine for other versions. Writing chunks and regions is broken from 1.16 onwards
