A class to hold chunk data for Minecraft: PC 1.8, 1.9, 1.10, 1.11 and 1.12 and Pocket Edition 0.14 and 1.0

const Chunk = require('prismarine-chunk')("1.8")
const Vec3 = require("vec3")

const chunk=new Chunk()

for (let x = 0; x < 16;x++) {
  for (let z = 0; z < 16; z++) {
    chunk.setBlockType(new Vec3(x, 50, z), 2)
    for (let y = 0; y < 256; y++) {
      chunk.setSkyLight(new Vec3(x, y, z), 15)
    }
  }
}

console.log(JSON.stringify(chunk.getBlock(new Vec3(3,50,3)),null,2))

Test data can be generated with minecraftChunkDumper.

Install it globally with npm install minecraft-chunk-dumper -g then run :

minecraftChunkDumper saveChunk 1.8.8 1.8/chunk.dump 1.8/chunk.meta

Benchmarks may be run by using:

# run benchmarks once
npm run benchmark

# run benchmarks continuously, reloading changes as they are made
npm run benchmark -- --watch

The output of the benchmarking will be placed in the file benchmarks/results/chunk-1.9.csv

Build a new chunk

Initialize a chunk.

• iniFunc is a function(x,y,z) returning a prismarine-block.

That function is faster than iterating and calling the setBlock* manually. It is useful to generate a whole chunk and load a whole chunk.

Get the Block at pos

Set the Block at pos

Get the block type at pos

Get the block data (metadata) at pos

Get the block light at pos

Get the block sky light at pos

Get the block biome id at pos

Get the block biome color at pos. Does nothing for PC.

Set the block type id at pos

Set the block data (metadata) at pos

Set the block light at pos

Set the block sky light at pos

Set the block biome id at pos

Set the block biomeColor at pos. Does nothing for PC.

Returns the chunk raw data
