prismarine-chunk

A class to hold chunk data for Minecraft: PC 1.8, 1.9, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15 and 1.16 and Pocket Edition 0.14 and 1.0

Usage

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

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

API

Chunk

Chunk()

Build a new chunk

Chunk.initialize(iniFunc)

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.

Chunk.getBlock(pos)

Get the Block at pos

Chunk.setBlock(pos,block)

Set the Block at pos

Chunk.getBlockType(pos)

Get the block type at pos

Chunk.getBlockStateId(pos)

Get the block state id at pos

Chunk.getBlockData(pos)

Get the block data (metadata) at pos

Chunk.getBlockLight(pos)

Get the block light at pos

Chunk.getSkyLight(pos)

Get the block sky light at pos

Chunk.getBiome(pos)

Get the block biome id at pos

Chunk.getBiomeColor(pos)

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

Chunk.setBlockStateId(pos, stateId)

Set the block type stateId at pos

Chunk.setBlockType(pos, id)

Set the block type id at pos

Chunk.setBlockData(pos, data)

Set the block data (metadata) at pos

Chunk.setBlockLight(pos, light)

Set the block light at pos

Chunk.setSkyLight(pos, light)

Set the block sky light at pos

Chunk.setBiome(pos, biome)

Set the block biome id at pos

Chunk.setBiomeColor(pos, biomeColor)

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

Chunk.getMask()

Return the chunk bitmap 0b0000_0000_0000_0000(0x0000) means no chunks are set while 0b1111_1111_1111_1111(0xFFFF) means all chunks are set

Chunk.dump()

Returns the chunk raw data

Chunk.load(data, bitmap = 0xFFFF, skyLightSent = true, fullChunk = true)

Load raw data into the chunk

Chunk.dumpLight()

Returns the chunk raw light data (starting from 1.14)

Chunk.loadLight(data, skyLightMask, blockLightMask, emptySkyLightMask = 0, emptyBlockLightMask = 0)

Load lights into the chunk (starting from 1.14)

Chunk.dumpBiomes()

Returns the biomes as an array (starting from 1.15)

Chunk.loadBiomes(biomes)

Load biomes into the chunk (starting from 1.15)

Chunk.toJson()

Returns the chunk as json

Chunk.fromJson(j)

Load chunk from json

Chunk.sections

Available for pc chunk implementation. Array of y => section Can be used to identify whether a section is empty or not (will be null if it's the case) For version >= 1.9, contains a .palette property which contains all the stateId of this section, can be used to check quickly whether a given block is in this section.
