Matt at Raspberry Pi Spy shares this Minecraft Pi Edition tutorial for how to Build Blocks (and Worlds) With Python Scripts Using the Minecraft Python API on a Raspberry Pi:

The great thing about the Raspberry Pi Edition of Minecraft is that you can manipulate the game world using Python scripts. You can move the player as well as create and destroy blocks. This allows you to create structures in seconds that would take hours to create by hand.

By repeating a script you can quickly create structures you have designed. For example you could write a script to create a tower and a section of wall and use it to quickly create a massive castle.

…To test your setup you can use the following simple script. It creates a cube made of stone and places you on top of it.

#!/usr/bin/python
# Import Minecraft libraries
import mcpi.minecraft as minecraft
import mcpi.block as block
 
mc = minecraft.Minecraft.create()
 
# Get player position
pPos = mc.player.getTilePos()
 
mc.postToChat("API Test!")
 
# Change block
print "Create stone 3x3 cube"
mc.setBlocks(pPos.x-1,pPos.y,pPos.z-1,pPos.x+1,pPos.y+2,pPos.z+1,block.STONE)
 
print "Position player on top"
mc.player.setPos(pPos.x,pPos.y+3,pPos.z)
 
mc.postToChat("Move and have another go.")

You can download this script directly to your Pi using :

wget https://bitbucket.org/MattHawkinsUK/rpispy-misc/raw/master/minecraft/api_test.py

It can be run using :

python api_test.py
Make sure Minecraft is running before you try the test script or nothing will happen! Pressing TAB will free the mouse from the game window and let you use the LXTerminal.

When the script has run you should see a stone cube under your feet….
