From the book: "Adventures in Minecraft" written by David Whale and Martin O'Hanlon, Wiley, 2017 http://eu.wiley.com/WileyCDA/WileyTitle/productCd-1119439582.html

Important note - Linux is not officially supported within Adventures in Minecraft and this Starter Kit is provided as is.

Description

This starter kit contains contains a pre-configured Minecraft server and a folder called "MyAdventures" which contains all the Python libraries required to complete all the chapters in "Adventure in Minecraft".

It is highly recommended that you use the Starter Kit as is and follow the instructions in Adventure 1 - "Hello Minecraft World" to setup your computer.

The structure of the StarterKit is as follows:

• AdventuresInMinecraft
  • Server : contains the pre-configured minecraft server and raspberry juice plugin
  • MyAdventures : folder to save the minecraft programs too
    • mcpi : python api library distributed with Minecraft: Pi Edition and minecraftstuff libraries
    • anyio : python library which contains the library to control the 7 segment display
    • microbit : python library which contains the library to control the microbit
    • findPort.py : a python program used in adventure 5 to find the com port a connected arduino uses
    • bitio.hex : the bitio microbit program which should be copied to the BBC micro:bit
  • StartServer.sh : a bash script used to start the minecraft server

StarterKit Creation Guide

If required the information below can be used as a guide to create your own StarterKit from scratch. It is written as guide, not as a precise series of instructions. There is no guarantee that they are accurate and are provided as is.

You can use either Bukkit or Spigot for the minecraft server.

Create folders

Create a folder AdventuresInMinecraft

Create a folder AdventuresInMinecraft\Server

Create a folder AdventuresInMinecraft\MyAdventures

Compile and run Bukkit

1. Compile the Minecraft server based on the instructions here (https://www.spigotmc.org/wiki/spigot-installation/) and put it in AdventuresInMinecraft\Server, the compiled bukkit jar file will be named craftbukkit-#.#.#-R#.0.jar where the # s are the current version number; make a note of the version number, you will need this later.

2. Rename the compiled.jar file from craftbukkit-#.#.#-R#.#.jar to craftbukkit.jar.

3. Open a text editor and insert the following text:

java -Xms1024M -Xmx1024M -jar craftbukkit.jar
PAUSE

4. Save the file to the Server folder as start.sh. The start.sh file is a bash program which will startup the Minecraft server when it is run.

5. Double-click the start.sh file to run it and startup the server.

6. Wait for the message You need to agree to the EULA in order to run the server.. Edit eula.txt so eula=true.

7. Run the start.sh file and startup the Minecraft server.

When you first start the Minecraft server it will take a little time to run as it sets up the server and creates a new Minecraft world, when its finished you will see the message Done in the command window.

When you want to start your Minecraft server in the future you can run the start.sh file.

To stop the server, enter the word stop into the command window and press Enter.

Configure Bukkit

1. Open a text editor, click File, Open and goto the Server folder and open server.properties.

2. Change the server.properties file:

   • gamemode=0 to gamemode=1 to change the server from survival mode to creative.
   • force-gamemode=false to force-gamemode=true to make all players play in creative mode.
   • spawn-monsters=true to spawn-monsters=false so monsters mobs wont appear in the game.
   • spawn-animals=true to spawn-animals=false so animals wont appear.
   • spawn-npcs=true to spawn-npcs=false so monsters mobs wont appear in the game.
   • allow-flight=false to allow-flight=true so you can fly in Minecraft.
   • online-mode=true to online-mode=false so you don t need to be connected to the internet to use Bukkit

Create StartServer.sh

Open a text editor and add the following text:

#!/bin/bash
echo "Adventures In Minecraft"
echo "Minecraft Server Version is #.#.#"
echo "  Note - make sure Minecraft is using #.#.#"
echo "By continuing you are indicating your agreement to our EULA https://account.mojang.com/documents/minecraft_eula)."
echo "Press any key to continue"
read -n 1 -s
cd "$( dirname "$0" )"
cd Server
./start.sh

Replace #.#.# with the version number of Minecraft server you created.

Save the file as StartServer.sh to the AdventuresInMinecraft folder.

Install RaspberryJuice

RaspberryJuice is a plugin for Bukkit which will allow you to write programs which will change the Minecraft world as you are playing, just like the API which comes with Minecraft: Pi Edition on the Raspberry Pi.

2. download the latest version of the raspberry juice plugin, download the raspberryjuice-#.#.jar file.
