const { LevelDB } = require('leveldb-zlib')
const { WorldProvider } = require('bedrock-provider')
const registry = require('prismarine-registry')('bedrock_1.17.10')
const Block = require('prismarine-block')(registry)
const ChunkColumn = require('prismarine-chunk')(registry)

async function main() {
  const x = 0, z = 0
  const cc = new ChunkColumn({ x, z })
  cc.setBlock({ x: 0, y: 1, z: 0 }, Block.fromStateId(registry.blocksByName.dirt.defaultState))

  // Create a new database and store this chunk in there
  const db = new LevelDB('./sample', { createIfMissing: true })
  await db.open() // Open the database
  // Create a WorldProvider instance from the DB with a prismarine-registry
  const world = new WorldProvider(db, { dimension: 0, registry })
  // Store this chunk in world
  world.save(x, z, cc)
  // Close it
  await db.close() 
  // Done! 😃
}

API

WorldProvider

constructor(db: LevelDB, options: { dimension?: number; registry });

The exported WorldProvider class allows you to load a save file from a LevelDB database. The first parameter is the db (leveldb-zlib instance), and the second is an options object. The options argument takes a dimension ID (overworld or nether or end are 1, 2 and 3).

The options argument also takes an instance of prismarine-registry, which will be used when doing block related calls.

load(x: number, z: number, full: boolean): Promise

This returns a ChunkColumn at the specified x and z coordinates. full if we should load biomes, entities, tiles, and other related data ontop of chunks.

save(x: number, z: number, column: ChunkColumn): Promise

Saves a ChunkColumn into the database.
