Minecraft and Ready Set STEM provide a number of APIs that allow us to manipulate blocks in various ways. We'll be using many of these APIs in upcoming projects, but in the meantime, we want to provide a general overview of the block functions, how they work and what arguments are required to make use of these functions.
Each block in the Minecraft world has a "type" (what the block is made out of) and each type of block can have additional characteristics associated with it (the block "data"). For example, blocks with the type "WOOD" can also have data associated with them that indicate the wood block is made from "Oak," or "Birch" or "Spruce."
Note that in Minecraft, everything is made of blocks, including the air. The blocks that make up the air in Minecraft function exactly the same as all other blocks, but have the specific type of "AIR." If you want to "remove" a block from Minecraft, you can change it's type to AIR.
The following sections list the most commonly used block-related functions provided in the Ready Set STEM API.
getBlock()
The getBlock()
function takes the location of a block (in X,
Y, Z coordinates) and returns the type of block at that location.
For example, to get the block type for the block at the location 0, 0, 0:
See below for the different types of blocks supported in the Minecraft Pi edition.
getBlockWithData()
The getBlockWithData()
function takes the location of a block
(in X, Y, Z coordinates) and returns the type of block at that location, along
with other characteristics of the block.
For example, to get the block type and data for the block at the location 0, 0, 0:
See below for the different types of block data supported in the Minecraft Pi edition.
setBlock()
The setBlock()
function takes a location (and optionally a set
of data) and places a block with that data type at the location.
For example, to place a wood block made of Oak at location 0, 0, 0:
setBlocks()
The setBlocks()
function takes two locations (and optionally a
set of data) and places a cuboid (three dimensional rectangular) set of blocks
with that data type at all the points between those locations.
For example, to place a set of 125 wood blocks made of Oak in a cuboid with one corner located at 0, 0, 0 and the farthest corner located at 5, 5, 5:
getHeight()
The getHeight()
function takes a two-dimensional X, Z location
and returns the height of the highest block at that location.
For example, to find the height of the highest non-air block at the location 0, 0:
