Session 1: Get Started With Python and Minecraft

- have fun with programming and game

Session 1.2 Start Learn Programming with Minecraft

1. Understanding the coordinates of Minecraft

Minecraft coordinates is different than what we learn from geometry. you need keep below picture in mind when you do the minecraft coding. coordinates of minecraft

To use below code example, please make sure use below code before the sample code.

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 to your user name"
mc = minecraft.Minecraft.create(address,4711,name)
pos=mc.player.getTilePos()

- [Mission-1.1] Find your location

Use mcpi module to find the position (x,y,z) of the block your player stand on. Use Python print command to display your location:

pos= #get your position
print("pos: x:{},y:{},z:{}".format(pos.x,pos.y,pos.z))

hint:

#return position with intiger number like (0,1,-10)
pos=mc.player.getTilePos()

# return posoition with float number like (1.02,1.23,-10.1)
pos=mc.player.getPos()

- [Mission-1.2] Find the block type id of the block you are standing

Use this link to check the name of the block type id:

heart Minecraft ID list

Use getBlock command to find the block type:

x=100
y=10
z=-10
id=mc.getBlock(x,y,z)
print("blockId:",id)

- [Mission-1.3] Teleport to an exact position

Let me know how you die after teleport to a position :)

Code example:

#move you to a given location
x=100
y=100
z=-10
print("teleport me to: x:{},y:{},z:{}".format(x,y,z))
mc.player.setTilePos(x,y,z)

- [Mission-1.4] Teleport you to one direction with 100 blocks

Find out how to move yourselfe to east 100, then north, then west, then top etc. use key F3 to check your location after transport.

- [Mission-1.5] Place a block on your location

Try place a watermelon beside you.

# place a block

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

mc.setBlock(x,y,z,103)

- [Mission-1.6] Use Python place multiple blocks point direction of x,y,z

Use python code to place color block like below

mc=Minecraft.create(serverAddress,pythonApiPort,playerName)
pos=mc.player.getTilePos()
(x,y,z)=pos=mc.player.getPos()

mc.setBlock(x+1,y,z,block.WOOL_GREEN)
mc.setBlock(x+2,y,z,block.WOOL_RED)
mc.setBlock(x+3,y,z,block.WOOL_BLUE)

xyz

2. Use Python loop Stack Blocks

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

Below mission only need using for ... range loop.

forloop

- [Mission-1.7]Stack 5 blocks without loop

You could repeat your code 5 times

x,y,z = pos = mc.player.getTilePos()
# place 5 block
id=103
mc.setBlock(x,y,z,id)
mc.setBlock(x,y,z,id)
mc.setBlock(x,y,z,id)
mc.setBlock(x,y,z,id)
mc.setBlock(x,y,z,id)

- [Mission-1.8] Stack 5 blocks by using `for` loop

Check below for range syntax, please build 5 pillars around you.

# for loop examplei
x,y,z = pos = mc.player.getTilePos()
id=103
for i in range(0,5):
   print("i=",i)
   mc.setBlock(x,y+i,z,id)

-[Mission 1.9] Try set blocks

to use the setBlocks, you need pass two set of blocks

mc.setBlocks(x,y,z,x1,y1,z1,blockId)

-[Mission 1.10][Challenge] use what you learn to build a house

Please use what you learn in this class to build a room. You could use loop or setBlocks with any blockId you like to use. Don’t forget set some place as windows and door. send your code to your teacher for review. stoneskin@gmail.com
