Minecraft + Scratch

Minecraft + Scratch 

    Scratch very useful coding application for everyone to learn what is logical. If you install ScratchGPIO and connect with Raspberry Pi then you can control a robot too (of cause with some sensor too). Scratch + Minecarft then you can control and create 3D Cartoon. It Fun !! 

Scratch with Minecraft

Simple Install Scratch2MCPI : curl http://scratch2mcpi.github.io/install.sh | sh
Simple Install Minecraft : curl http://scratch2mcpi.github.io/mcpi.sh | sh

    After Install
  • Open Minecraft
  • Open Scratch2MCPI


How to Run Python Script 

  • Open Minecraft : ./minecraft-pi
  • Open Terminal and Go to ~/Python_Minecraft
  • Run Python Script : python <script name>.py


  • HOME PAGE : http://pi.minecraft.net
  • wget https://s3.amazonaws.com/assets.minecraft.net/pi/minecraft-pi-0.1.1.tar.gz
  • To decompress it: tar -zxvf minecraft-pi-0.1.1.tar.gz
  • To run it: cd mcpi
  • Followed by ./minecraft-pi
  • https://minecraft.net/
  • Create Desktop Icon (Minecraft.desktop on XScreen)
    • [Desktop Entry]
      Name=Minecraft Pi Edition
      Comment=Launch Minecraft Pi Edition!
      Exec=sh -c 'cd ~/mcpi && lxterminal -l -t Minecraft -e ./minecraft-pi'
    • Using Minecraft : This isn’t the place to give an extensive guide to using Minecraft but I thought I would present some basics to get you moving around the environment.
      ESC  Pause/Menu
      W    Move forward
      A    Move left
      S    Move backwards
      D    Move right
      E    Show inventory of blocks
      1-8  Select items in the quick-bar
      Left mouse  Destroy blocks
      Right mouse Place blocks
      Space  Jump (ascend in fly-mode)
      Shift  Sneak (descend in fly-mode)

      The mouse can be used to change your point-of-view. The scroll wheel can be used to scroll through the items, the left mouse button being used to select a block. When viewing the inventory you can use the WASD keys to move the selection using the Enter key to select a block.

      Double-tapping the Space bar will activate and deactivate fly-mode.

      You can exit Minecraft by clicking the [x] in the top right hand corner of the game window

Problem and Solution

Control Minecraft by Scratch :
  • Open Minecraft 
  • Open ScratchMCPI
  • if open New Scartch File then it have to open the Scratch2MCPL terminal Again
