Minecraft Script Programming language

Minecraft Script

Minecraft script is primarily a tool to make Minecraft Datapack creation easier.

Minecraft Script is an interpreted programming language which goes through the Python interpreter for output.

However, interpretation is not its main feature, and is rather more of a debugging tool, as its sole

purpose is to allow you to validate your code before building it into a full datapack.

Commands

python -m minecraft_script help

python -m minecraft_script run [files: optional, multiple allowed]

python -m minecraft_script build [file]

Objects

Variables

The var keyword can be used to initialize new variables.

It can either be simply followed by a variable name, in which case it will default to 0,

or you can directly assign a value to it.

var hello1;  // initalized variable "hello1" with value 0 (default)

var hello2 = 500;  // initialized variable "hello2" with value 500



hello2 = 300;  // assigned new value 300 to variable hello2

hello2 = hello2 + 500;  // adds 500 to hello2



logtype hello2; // logs "var" in the console

log hello2;  // logs "800" in the console

Constants

The const keyword can be used to initialize and define new constants.

Unlike vars, these cannot be reassigned new values. Trying to initialize

a new constant without a value brings raises a Syntax Error.

const hello1;  // raises 'Syntax Error: Missing value in const declaration'

const hello1 = 500;

hello1 = 300;  // raises 'Type Error: Tried to assign new value to const "hello1"'



logtype hello1;  // logs "const" in the console

log hello1;  // logs "500" in the console

Functions

Functions are defined with the "function" keyword. They can be anonymous,

or be attributed a name. Parentheses around the arguments are required (currently, subject to change).

function = (a) => a * 3  // anonymous function



function add = (a, b) => a + b  // define a simple add function

add(2, 7)  // call the function; returns 9

Console logging

Console logging values with log

Logging values in MCS is as simple as typing "log", followed by an expression.

Example:

var hello1 = 500;

const hello2 = 600;



log 200 + 200;  // logs 400 in console

log hello1;  // logs 500 in console

log hello2;  // logs 600 in console

Console logging types with logtype

Logging types in MCS is equally as simple. To log an object's type, simply type "logtype" followed by the object.

Example:

var hello1 = 500;

const hello2 = 600;



logtype 400;  // logs "number" in console

logtype hello1;  // logs "var" in console

logtype hello2;  // logs "const" in console
