minecraft-region's Introduction

minecraft-region

parses chunks out of a minecraft region file

extracted from code originally written by @ithkuil for mcchunkloader, turned into a module and now maintained by @maxogden

minecraft is property of Mojang AB

var mcRegion = require('minecraft-region')
var region = mcRegion(binaryRegionData) // from a .mca file
var chunkX = 0
var chunkY = 0
if (region.hasChunk(chunkX, chunkY))
  var chunk = region.getChunk(chunkX, chunkY)

now use the chunk with minecraft-region to get voxel data

this module works with minecraft-chunk and is used by minecraft-mca

designed for use with browserify

minecraft-region's Issues

Zlib problem in getChunk method

I'm trying to view and manipulate mca data in node.js. I'd like to use the getChunk(x, y) method, but it's been giving me trouble. Here some test code I used to see if I could read chunks. It's a modified version of the test.js file in the repo.

mcRegion = require('./')
var fs = require('fs')
var mcaData = fs.readFileSync('r.0.1.mca')
var region = mcRegion(mcaData)
console.log('region loaded')
console.log(region.getChunk(0, 0))

Here's the output I'm getting:

region loaded
[ommited path info]/zlibjs-node.js:2
(function() {'use strict';function m(a){throw a;}var p=void 0,u=!0;var A="unde
                                              ^

    at Module.load (module.js:355:32)
    at Function.Module._load (module.js:310:12)

I'm using node v0.12.2. Also tried with node v0.10.40 and got the same error. The only other thing I tried was changing line 5 in index.js from

 else var Zlib = require('./zlibjs-node')

to

 else var Zlib = require('zlib')

That gave me the following output:

region loaded
zlib.js:236
    throw new TypeError('Not a string or buffer');
          ^

Any help would be much appreciated.
