Introduction to Minecraft PiAims:

To know what Minecraft isTo learn how to enter code into Minecraft Pi

To successfully enter at least 2 Python programs into Minecraft Pi

What is Minecraft Pi?

Minecraft is a program which lets you build virtual worlds, block-by-block, in a range of different materials.

You get a basic world given to you, it is then up to you what goes into it.

Minecraft Pi is an early development version of Minecraft Pocket Edition for phones & tablets.

Minecraft is deliberately ‘blocky’ like LEGO, because it is easy to build when your bricks are the same shape!

The blocks are deliberately NOT highly detailed as this means the graphics can be drawn/updated quickly as you move around.

The Pi edition is special because it is not ‘locked down’ so you can code straight into it and make ‘Magic happen.’

“It looks rubbish!”

You will need to arrange 2 program windows on your desktop Minecraft Pi Python 2

Python is a programming language you will use to interact with Minecraft (make buildings, show messages, etc.)

Load BOTH programs and arrange your screen like this…

Get Set…

In Python, you have the window to store the program code AND a window where it runs. You need to type your code into this window

Get the right Python

Minecraft & Python Screens

To enter your code, you click

FILE and NEW… To move the mouse out of

Minecraft, press the TAB key first

Have a quick look

around your

world, before we

move on

Start a new Python window, by clicking ‘File’ and ‘New.’

Click in your new empty Python window and type this code.

import mcpi.minecraft as minecraftmc = minecraft.Minecraft.create()msg = “Hello world”mc.postToChat(msg)

Click on File and save your code in yourPi ‘Documents’ folder as text.py

Try another few. What happens withlong sentences?

Text Messages

Capital letters and spaces MUST

be correct, or your code won’t

work

Graphs use X co-ordinates for left-right and Y co-ordinates for up-down.

Minecraft is a 3D game, so also has forwards-backwards movement.

X = Left-RightY = Up-DownZ = Forward-Backward

Where am I?

There I am!( -3, 33, 97 )

Start a new Python window by clicking ‘File’ and ‘New’. Click in this new window and type this code.

import mcpi.minecraft as minecraftimport time

mc = minecraft.Minecraft.create()

time.sleep(1)pos = mc.player.getPos()mc.postToChat(“You are located x=“ +str(pos.x) + “, y=“ +str(pos.y) +”, z=“ +str(pos.z))

time.sleep(2)mc.postToChat(“Get ready to fall from the sky!”)

time.sleep(5)mc.player.setPos(pos.x, pos.y + 60, pos.z)

Click on File and save your code in your Pi ‘Documents’ folder as teleport.py

TeleportingIf you can’t read the code, ask for

a worksheet

You can now choose your next challenges. These are:

Challenge Sheets

EASY HARD EXTREME

Teleporting Instant Buildings Treasure Hunt

Flower Stalk Building Bridges Whack-a-mole!

Melon Teleporter

These do get difficult, so do try both Easy and at least 2 Hard sheets before doing the Extreme level

With a Raspberry Pi camera you can even Minecraft your face!
