Minecraft + Python Challenges

Learning Objectives

Another approach to boost your pogramming skills is to learn how to code for Minecraft. Using Python code you can interact with the Minecraft world to for instance move the player or add blocks to build structures.

For this challenge we are using a Raspberry Pi with Minecraft and Python 2 pre-installed.

Let’s see how this works…

Hello Minecraft World

Let’s start by writting a “Hello World” program that will write a welcome message on the Minecraft chat. This is the simplest program and will be useful to make sure we have the required library and can connect to Minecraft.

Here is the Python code:

So to test this program on your Raspberry Pi you will need to:

  • Type this program in your Python IDE (e.g. IDLE) for Python 2,
  • Launch Minecraft
  • In your IDE run the program
  • Check the Minecraft screen. If everything goes right, a message will appear on screen.

Teleporting your player

minecraft-xyz-coordinatesFor this Python script we are going to write a function to teleport the player up in the sky. We will call this function “jump”. It will take one parameter: the distance (number of blocks) we want the player to jump (up in the sky).

To understand the code below we need to understand how (X,Y,Z) are used in minecraft to retrieve or change the position of a player (and later on the position of blocks).

Building a Tower

minecraft-postThe purpose of this script is to build a ten-block high tower in front of the player. We will be using 3 different methods for you to compare:
  • Method 1: Building the tower one block at a time using sequencing,

  • Method 2: Building the tower one block at a time using iteration (for loop),

  • Method 3: Building the tower in one go using the setBlocks(), method.

Challenge #1: Rugby Post

minecraft-rugby-postUse any of the three methods mentioned above and complete the code to create a full rugby post using Python.

Challenge #2: A complex Structure

Build a complex structure using a Python script. Try to identify patterns in your structure to use for loops and hence reduce the number of instructions in your program.

Try to build a Pyramid first starting from a 10 by 10 square base.

Or why not challenge yourself to build a castle like this one:
