MCBlocks

MCBlocks is a three dimensional esoteric programming language created by User:Dominicentek. It's code is written as a build in a Minecraft world with each block representing a command that the interpreter follows. The interpreter accepts .nbt files exported by Structure Blocks. The command pointer starts at XYZ 0 0 0 of the structure moving in X+ direction. Because of the Structure Block limit, each program is limited to 48x48x48 grid.

Blocks

Block	Description
Oak Planks	Moves the command pointer X+
Spruce Planks	Moves the command pointer X-
Birch Planks	Moves the command pointer Y+
Jungle Planks	Moves the command pointer Y-
Acacia Planks	Moves the command pointer Z+
Dark Oak Planks	Moves the command pointer Z-
Dirt	Pops a value off the stack
Cobblestone	Reverses the stack
Stone	Swaps the first 2 values
Deepslate	Duplicates the top value on the stack
Cobbled Deepslate	Pushes a number of values currently on the stack (This number not included)
Block of Iron	Pops two values X and Y, performs a Math operation Y + X and pushes the result
Block of Coal	Pops two values X and Y, performs a Math operation Y - X and pushes the result
Block of Gold	Pops two values X and Y, performs a Math operation Y × X and pushes the result
Block of Diamond	Pops two values X and Y, performs a Math operation Y ÷ X and pushes the result
Block of Netherite	Pops two values X and Y, performs a Math operation Y % X and pushes the result
White Wool ... Black Wool	Pushes current wool color on the stack (White = 0, Orange = 1, Magenta = 2, ..., Black = 15)
Sign	Pushes ASCII characters of the sign on the stack (multiple lines are joined by a space, empty lines are ignored)
Block of Lapis Lazuli	Asks user for number input
Block of Emerald	Asks user for string input (ASCII values will then be pushed)
Block of Quartz	Outputs top value of the stack as a number
Block of Redstone	Outputs top value of the stack as an ASCII character
Oak Log (Rotated in X axis)	If the top two values match, The command pointer moves X+, otherwise it moves X-
Oak Log (Rotated in Y axis)	If the top two values match, The command pointer moves Y+, otherwise it moves Y-
Oak Log (Rotated in Z axis)	If the top two values match, The command pointer moves Z+, otherwise it moves Z-
Crimson Hyphae	Pops two values off the stack X and Y. X is used as address and Y is used as value. Value is then put on the corresponding address in the heap memory.
Warped Hyphae	Pops a value off the stack used as an address. It pushes a value on the stack that is on that address in the heap memory. If there is no value, a 0 is pushed.
Red Concrete	Ends the program
