1 RICK WARGO - APRIL 2016 PROGRAMMATIC INTERFACES TO MINECRAFT

2 INSPIRATION

3 RESOURCES Minecraft Pi Edition Runs on the Raspberry Pi Very old functionality Raspberry Juice Plug-in Server-based installation Based on Bukkit Minecraft Pi API mod For Minecraft

4 RASPBERRY JAM MOD! Gives similar functionality to other paths Available on desktop Minecraft 1.8, 1.9 Can control most of what is available in Minecraft Often can be installed with other Mods (Pixelmon, Life In The Woods) Can execute Python code within Minecraft and outside of Minecraft

5 INSTALLATION Adding Mods to Minecraft is not Difficult! It is if you try to Interpret the YouTube videos. Overview Install Minecraft (let s assume this is complete - need an account) Install Forge (gives modding capability) Install Python Install mod(s) Install MCPI scripts

6 INSTALL FORGE FOR MINECRAFT 1. Run Minecraft once to initialize 2. Set up a new profile for the version you want to play (1.9 is latest Forge) 3. Click play to make sure that it worked It will download all necessary objects 4. Exit Minecraft and Minecraft Launcher 5. Download Forge for Minecraft (ensure it is the same version as Minecraft) - these tools are all similarly monetized. I m not concerned (yet).

7 INSTALL FORGE FOR MINECRAFT (CONT D) 1. Run Forge and Install Client in Default Directory It will download any necessary libraries (e.g. scala) 2. Start Minecraft, select new forge profile You should see 3 mods loaded, 3 mods active This is what winning looks like! You can now install any mod you desire. 3. If not, delete directory and start over

8 INSTALL FORGE FOR MINECRAFT (CONT D) 1. Press F3 (F3 is your friend) 2. Do your self a favor and up the memory limits in the forge Profile Update JVM Arguments to give more memory! -Xmx2G -Xmn1G (at least 1GB memory devoted to Minecraft) 3. You can change the profile name if you desire

9 INSTALL PYTHON I have had success with Python 2.7 It may also work with Python 3.x Install Python Insure the Python executable is in the PATH

10 INSTALL MODS AND SCRIPTS Minecraft is installed to: [Windows] %appdata%\.minecraft [OS X] ~/Library/Application Support/minecraft In a command line window create a mods folder if it does not exist Download the latest mods.zip file for the Raspberry Jam mod Unzip the contents of the zip file (currently four folders: 1.8, 1.8.8, and 1.9) inside the mods folder Download the Python scripts and mcpi library (in the python2-scripts.zip file) Unzip the contents of the Python Scripts file into the minecraft folder, leaving you with an additional folder mcpipy. Start minecraft again. You will now see 4 mods loaded, 4 mods active

11 FILES

12 TEST IT OUT! Hint: Don t use important worlds as it is easy to ruin things. Create a new world, suggest using Game Mode: Creative World Type: Superflat After starting type: /python donut Try other scripts after moving to a new location. Check the previous slide for examples.

13 RENDER MODELS! /python render stardestoyer (may take a while) Other models installed by default: 1701d City_Ground-Notts NY_LIL RaspberryPi atat bop neghvar redstardestroyer shuttle skyscraper stardestroyer yt1300 cessna cube dragon ds9 head humanoid_quad jemcruiser

14 HELLO, WORLD! import sys sys.path.insert(0, '/Users/rick/Library/Application Support/minecraft/mcpipy') from mc import * mc = Minecraft() mc.posttochat("hello, world!") This can also be done from command line or IDLE interactively Start python from minecraft/mcpi directory to avoid changing path dynamically Watch it appear as you press Return

15 MORE FUN - A CASTLE!

16 STOP AUTO-PAUSE Edit options.txt in minecraft folder Find pauseonlostfocus:true Edit options.txt in minecraft folder Change true to false and restart minecraft

17 TEACH YOUR KIDS TURTLE GRAPHICS from turtle import * t = Turtle() for i in range(7): t.go(50) t.right( /7) An excellent overview exists at:
