This is a complete rewrite of the original pymclevel by Codewarrior0. The rewrites focus to make an easily extend-able library that can support multiple world formats without having to modify other world formats for compatibility. This library is in it's alpha stages, if you would like to help, please refer to the TODO section later in this document

• Python 2.7+ (Python 3 is not supported)
• numpy (Preferably >=1.13.3)

After installing the requirements, please copy the blockstates directory from a Minecraft .jar into the base repository directory. This cannot be included in the repository due to legal concerns.

How to access Blocks in a world:

import os
import format_loader

world = format_loader.load_world(os.path.join('tests', '1.13 World'))
chunk = world.getChunk(0,0)
print chunk.Blocks[0,0,0] # minecraft:bedrock

How to get a Blockstate object (still very much a work in progress)

import materials
mats = Materials('1.11') # Replace '1.11' with the Minecraft version you want to load, only 1.11 is complete as of 3.7.2018
stone_blockstate = mats['minecraft:stone[variant=stone]'] # Get Blockstate by string
dark_oak_planks_blockstate = mats[(5,5)] # Get Blockstate by numerical ID and data pair
oak_planks_blockstate = mats[5] # Get Blockstate by numerical ID, assumes data value of 0

print(stone_blockstate) # minecraft:stone[variant=stone]
print(dark_oak_planks_blockstate) # minecraft:planks[variant=dark_oak]
print(oak_planks_blockstate) # minecraft:planks[variant=oak]

The library is missing many functions that are present in the original pymclevel, but feature parity is slowly improving

• Common access point to load a world
• Have the world loader find world formats at runtime
• Load a Blockstate chunk from a .mca region file and decode the Blockstate array
• Re-encode the Blockstate array so Minecraft can load the modified world
• Add missing functions to the api and the Blockstate format module
• Add anvil support
• Complete the tests module so we have comprehensive testing of the library
• Add in missing functionality of the original pymclevel
