Convarter

An android app that allows you to edit Minecraft (MCPE) gamemaps with javascripts, create customized flat levels and other features.

Now supports gamemap editing using BlockLauncher-style javascripts.

• Basics:
  • getBlock(x,y,z) returns block runtime id.
  • setBlock(x,y,z,runtimeId) sets block runtime id.
  • A runtimeId is just (id << 8) | data for now.
  • getTile(x,y,z) returns block id as legacy support.
  • getData(x,y,z) returns block data as legacy support.
  • setTile(x,y,z,id,data) sets the block's id and data as legacy support.
• With multi-dimension (Overworld/Nether/...) support:
  • getBlock2(x,y,z,dim) returns block runtime id.
  • setBlock2(x,y,z,dim,runtimeId) sets block runtime id.
  • dim = 0 for Overworld, 1 for the Nether, -1 for the End.
• With two-block-coexist support:
  • getBlock3(x,y,z,dim,layer) returns block runtime id.
  • setBlock3(x,y,z,dim,layer,runtimeId) sets block runtime id.
  • layer = 0 or 1. The purpose of layer 1 is to allow block coexisting with another.

With this app you can generate huge and complex things in Minecraft that are hard or impossible to be build manually or using in-game scripts.

Ideas

• Place sand, torch and cactus in space...
• Music railway with super long musics...
• Huge structures...
• Convert HDL files into redstone circuits...
• Import 3D models and...
• Well, everything up to you...

Features that may be added

• Convert a game map back to 0.x format.
• Make portals invisible and single-directioned.

Library projects used

• F43nd1r's Rhino-android to enable script optimization.
• Mozilla's Rhino, a javascript environment.
• SimpleNBT, read|write nbt files e.g. level.dat. Originally SpoutDev's work, forked by Boomshroom, since spout was gone.
• Google's Dx tool. Here we uses a repacked version:'com.jakewharton.android.repackaged:dalvik-dx:7.1.0_r7'
• leveldb-mcpe-android thanks to
  • @litl's,
  • @mojang's and
  • @google's work.
• Inspired by reverse engineering @zhuowei's apps. Anyway we're not just copying.
