📦 Mod Description
This mod adds four blocks to help you run Brainf**k programs in Minecraft — a minimalist yet Turing-complete programming language.
🧠 Brainf**k Overview
Brainf**k programs are made up of only 8 symbols:
< and >: Move the pointer left and right across memory. In this mod, this is visualized as the pointer block moving left or right.
+ and -: Increment or decrement the value at the current memory cell.
[ and ]: Create loops. When the program reaches [, if the current cell is 0, it skips to the command after the matching ]. When it reaches ], it jumps back to the matching [.
.: Outputs the value of the current memory cell as an ASCII character.
,: Reads a single character of input and stores its ASCII value in the current memory cell (not yet implemented in this mod).
🔧 Mod Features
Pointer Block Simulates the pointer in Brainf**k. Right-click to open the GUI and edit the program; Shift + Right-click to run it. The block the pointer is facing represents the current memory unit. Output is displayed above the block. It might explode.
Memory Unit: The basic memory block. Its value can be modified by the pointer. Supports negative numbers.
Chance Block: Get random number(1-6 or (-1)-(-6)).
Boolean Unit:
Has two states: True and False. Can be toggled using + and -.
Color Unit:
Displays a color. The + and - commands adjust RGB values. By default, they modify red. Use . to cycle between which color is being modified (e.g., first press affects green, next affects blue, etc.).
