Minecraft Blocks Cheatsheet

10 December 2016

codeminecraft

There are a huge number of block types available to build through the Python API.

Example

Typically you use the upper case block name and id in the call to setBlock but there’s nothing stopping you from using the plain integer value.


import mcpi.minecraft as minecraft
import mcpi.block as block

world = minecraft.Minecraft.create()

stone_id = 1
world.setBlock(x, y, z, stone_id)
world.setBlock(x, y, z, block.STONE.id)

Special Blocks

Some special blocks support extra attributes in the final argument to setBlock. Wool, for example, supports a colour value.

ID Colour
0 White
1 Orange
2 Magenta
3 Light Blue
4 Yellow

So I can make a lovely block of orange wool like this:


mc.setBlock(x, y, z, block.WOOL, 1)

There are a few others but they are not called out in the API as block ids. There is a more comprehensive guide to blocks and optional attributes.

Bigger building

Rather than building structures block by block, you can use a similar call to build a cuboid given two sets of coordinates and a block type. setBlocks fills in the volume between the two 3D points with blocks of the right type.


height = 10
width = 5
length = 15

world.setBlocks(x, y, z, x + length, y + height, z + width, block.STONE.id)

House Full of Hollow

To create a hollow structure, like a house, you can create a large block of stone, then adjust the coordinates and re-fill that volume with AIR.


height = 10
width = 5
length = 15

wall_thickness = 1

world.setBlocks(x, y, z, x + length, y + height, z + width, block.STONE.id)
world.setBlocks(x + wall_thickness, y, z + wall_thickness,
                x + length - wall_thickness, y + height, z + width - wall_thickness,
                block.AIR.id)
