Setting up minecraft for most recent version with Spigot and python api

Python3.6 or newer with venv module Java 8 (JRE and JDK — openjdk is great)

Build for specific version of MC: java -jar BuildTools.jar —rev 1.14.4

Run server: java -Xms512M -Xmx1024M -XX:MaxPermSize=128M -jar spigot-1.14.4.jar

(you may be required to accept the EULA by editing the text file it tells you about)

After the server has run successfuly, enter a stop command

This package is needed to setup the correct API routes for python Install maven:

Build the raspberry juice package:

git clone https://github.com/zhuowei/RaspberryJuice cd RaspberryJuice mvn package 

Copy the produced file to the Spigot plugins directory: cp target/raspberryjuice-1.11.jar ~/mc_python/plugins/

Setup Python virtual environment and get py3minepi

1. Create a working directory for your python files
2. Get Mac minecraft tools (they say for Mac, but all you need is the python package): https://sourceforge.net/projects/program-with-minecraft-mac/
3. Extract the download and copy the folder, py3minepi-master to your working directory
4. in your working directory, create a python virtualenv with: python3.7 -m venv py
5. activate the virtualenv: source py/bin/activate
6. install the py3minepi package: pip install ./py3minepi-master

1. start the server: (you may need to fill in a full path for spigot-n.nn.n.jar) java -Xms512M -Xmx1024M -XX:MaxPermSize=128M -jar spigot-1.14.4.jar
2. start minecraft and login to the localhost minecraft server

• get somewhere in the game where you wont immediately die.
• alt-tab out to the terminal

1. With the python virtual environment activated source py/bin/activate start a python console session by simply typing python
2. Import and enter a test command:

>>> from mcpi.minecraft import Minecraft >>> mc = Minecraft.create() >>> mc.player.getTilePos() Vec3(117,2,-63) 

It’s important to note that this vector is not your absolute position in the world, but your position relative to your spawn point.

  • Click to download VsCode
  • How to install VsCode for python

  1. Get Start Python with Minecraft

  1.1 Connect to the Minecraft server and get your position

  Create a Python project folder, Download and save the sample1.py file to your python project folder

  from mcpi_e.minecraft import Minecraft serverAddress="127.0.0.1" # change to your minecraft server pythonApiPort=4711 #default port for RaspberryJuice plugin is 4711, it could be changed in plugins\RaspberryJuice\config.yml playerName="stoneskin" # change to your username mc = Minecraft.create(serverAddress,pythonApiPort,playerName) pos = mc.player.getPos() print("pos: x:<>,y:<>,z:<>".format(pos.x,pos.y,pos.z)) 

  Use your faverate python editor to open the sample1.py file. When you install python, it come with a python editor call IDLE.j

  1.2. Frequently used mcpi commands

  1.2.1 Find your location

  1.2.2 Teleport

  move player to north 100 block

  x,y,z = pos = mc.player.getTilePos() mc.player.setTilePos(x,y+100,z) 

  1.2.3 Set block

  set the a stone block beside the player

  x,y,z = pos = mc.player.getTilePos() mc.setBlock(x+1, y, z, 1) 

  setblock with constants block.STONE.id

  #setblock with constants block.STONE.id from mcpi_e import block (x,y,z) = pos = mc.player.getTilePos() mc.setBlock(x+1, y, z+1, block.STONE.id) 

  set special block which extra properties

  # set special block which extra properties flower = 38 flowerColor = 3 mc.setBlock(x+1, y, z+1, flower, flowerColor) 

  1.2.4 Get block

  get the block type id of the player stepping on

  # get the block current player step on x, y, z = mc.player.getTilePos() blockId= mc.getBlock(x, y, z) if(blockId == 0): print("current block is Air") 

  2 Learn Python With Minecraft

  To use the code examples in this site, please make sure include the piece of code below before the sample codes

  import mcpi_e.minecraft as minecraft import mcpi_e.block as block from math import * address="127.0.0.1" # change to address of your minecraft server name ="change you your name" mc = minecraft.Minecraft.create(address,4711,name) pos=mc.player.getTilePos() #your other code below . 

  2.1 Understand the coordinates of minecraft

  

  Minecraft coordinates are different than what we learn from geomestry. You need keep the picture below in mind when you do the minecraft coding.

  For basic python syntax, pleas check Python syntax for details.

  The missions/codes below will use print and command from minecraft api mcpi

  Click to view your Mincraft-Python Missions-1

  2.2 Use for Loop to stack blocks

  for loops are traditionally used when you have a block of code which you wnat to repeat number of times.

  for x in range(0, 3): print("We're on time %d" % (x)) 

  For learnning how to use for loop, please visit Python For Loops

  Below mission only need using for . range loop.

  Click to view your Coding Missions -2

  2.3 Value Type: String , Number

  In Python any amount of text call a string , you could use string like this

  print("Hello Minecraft") name ="Steve the Miner" print(name) 

  String and Intiger is different DataType, for detail please read Python Data Types. Below is the Data Types we possible will used in our class

  

  example of get type of a variable:

  The data you got form input is a string, we need convert to number before using as number. int(str) could do this job.

  blockType=input("Enter a block type:") blockTypeId=int(blockType) 

  other way if you want change a int to string, you could use str(number)

  value=103 print("Watermelon block id is "+str(value)) 

  Click to view your Coding Missions -3

  2.4 Use Condition if . else

  To learn comdition please check Python If…Else

  Booleans represent one of two values: True or False

  For learn more and practic Boolean, please check Python Boolean

  

  Click to view your Coding Missions -4

  3 More Code Samples

  3.1 Dropping the flowers when you move

  Set a random flower on where the play is standing

   flower = 38 while True: x, y, z = mc.playerEn.getPos() blockId= mc.getBlock(x, y, z) print("current block:" + str(mc.getBlock(x, y, z))) if(blockId==0 or blockId ==78): mc.setBlock(x, y, z, flower,randrange(8)) sleep(0.2) 

  

  3.2 Build a rainbow in the minecraft

  code example: rainbow.py build a rainbow with colored wool on the player’s location

   import mcpi_e.minecraft as minecraft import mcpi_e.block as block from math import * address="127.0.0.1" # change to your minecraft server name ="change you your name" mc = minecraft.Minecraft.create(address,4711,name) playerPos=mc.player.getTilePos() colors = [14, 1, 4, 5, 3, 11, 10] height=50 for x in range(0, 128): for colourindex in range(0, len(colors)): y = playerPos.y+sin((x / 128.0) * pi) * height + colourindex mc.setBlock(playerPos.x+x - 64, int(y), playerPos.z, block.WOOL.id, colors[len(colors) - 1 - colourindex]) print("rainbow created at x:<> y:<> z:<>".format(playerPos.x,playerPos.y,playerPos.z))

  Installing Minecraft¶

  The software used for this course is provided as companion to the book Learn to Program with Minecraft. It is recommended that the students purchase the book.

  To get things running, you will need:

  1. Minecraft
  2. Python 3
  3. Java
  4. Minecraft Python API
  5. The Minecraft server

  Minecraft¶

  Visit the Minecraft homepage to download. If you do not have an account, please email me and I will make sure you are provided with one.

  Python 3 Distribution¶

  Python 3 is the distribution we will be using. If you have Python 2, it is recommended that you uninstall Python 2 and install Python 3. If you don’t, there will be some inconsitencies that could be devestatingly confusing. Also, Python 3 has a lot of really cool, new features that aren’t in Python 2.

  There are several ways to get Python. I personally recommend the Anaconda distribution. It has a bunch of things packaged with it above and beyond Python that make it useful. Anaconda comes with the Spyder editor. It is a decent editor, but I would recommend:

  • PyCharm.
    • If you download PyCharm, make sure you download the Community Edition.
    • This is my personal favorite. It is lightweight and has many extensions.
    • However, it does not run or debug Python files as easily as PyCharm.
    • Very similar to Sublime

    Java¶

    You should have both Minecraft and Python installed at this point. You need to set Java up in order to run the server.

    1. Click the Start Menu (or press the Windows key)
    2. Type “cmd” to find the program called cmd. Open this.
    1. Type java -version at the prompt
    2. If you see an output describing the version of Java, you already have it and can continue to the next section.
    3. If you don’t, or it can’t find java, then go to here: http://www.java.com/en/download/
    4. Click Free Java Download. Then click Agree and Start
    5. When it is finished downloading, install this.
    6. IMPORTANT: If it asks you to install extra things or set Yahoo! as your homepage, click no.

    Minecraft Python API and Minecraft Spigot server¶

    An API is an interface. We will use it as a library that lets us communicate with the Minecraft server. We will not be able to edit the server in any way, but instead, just tell it instructions.

    We will be using the Spigot server because it allows for the API to talk to it. Standard Minecraft does not.

    1. Go to https://www.nostarch.com/pythonwithminecraft/
    2. Download the MinecraftTools.zip for your operating system.
    3. When it has finished downloading, you can open it.
    • a zip file is known as a compressed file
    • it allows you to compress a set of files to make them smaller for downloading
    • all operating systems let you open these files
    1. Important Although it looks like you have a folder, the contents of the Zip file are not a folder
    2. Create a folder somewhere convenient and name it MinecraftTools.
    3. Inside the Zip file, you can click “Extract all” or similar button.
    4. Extract it to your MinecraftTools folder.
    5. Go to the folder and double click the Install_API file.
    6. Now, you can run the server.
    7. There is a file called Start_Server. Running this will start the server.
    8. If you have any trouble, email me.
