Fungecraft – a Minecraft programming language

The most basic instruction is the beginning and end. To begin a program, place down a stone block. Then, whilst looking at that block, run the command /trigger fungecraft.play. This should start the program 1 block south of the stone. The execution will continue south until it hits a directional operator, or bedrock, which terminates the program.

The directional operators are magenta glazed terracotta, which looks like an arrow, and when the program pointer reaches one of them, it continues in the direction the arrow is pointing.

Then there are the mathematical operations.\
There is addition, which is represented by an oxidised cut copper block,\
Subtraction, which is a jukebox,\
Multiplication, which is a honeycomb block,\
Division, reperesnted by light blue glazed terracotta,\
And modulo, nether quartz ore.\
Each of these pops two values from the stack, a then b, and pushes back on the operation calculated with b and a (e.g. if the stack had a 2 then a 3, then you put a minus operation, it would pop 3 then 2 and push 2 – 3)
