Python experiments for Minecraft API (mcpi) to make ridiculous cubes & towers.

minecraft-cubes-and-towers.py

"""
  Make cubes and towers in Minecraft, with Python.
  
  Really fun way to introduce a kid to Python (or yourself to Minecraft, as I've learned).

  Setup instructions for Minecraft + macOS + Python: https://gist.github.com/noahcoad/fc9d3984a5d4d61648269c0a9477c622

  Additional setup:
    - Activate correct Java version: `export JAVA_HOME=`/usr/libexec/java_home -v 11.0.5``
    - Activate spigot `cd spigot; java -jar spigot.jar`
    - Open Minecraft, make installation of v13.0.1, go into Multiplayer, join server `localhost`, and then run this script
