Four integers are enough to write a Snake Game

10 months ago

A Snake Game can be implemented using only 4 integers (or even 2 with added difficulty).
The game map is stored in a `uint32_t`, representing a 4x8 grid where bits indicate the snake's body.
A `uint64_t` is used as a directions array to manage the snake's movement and growth.
Another `uint32_t` stores positions of the head, tail, apple, length, and keyboard input (using bit manipulation).
An `uint8_t` variable is used for looping.
The implementation relies on the `curses` library for keyboard input, which is not standard in C.
Bitwise operations and macros are heavily used to minimize memory usage and optimize performance.
The snake's movement and growth are managed by updating the directions array (`shape`) and the map.
The game loop includes rendering the map, handling keyboard input, and updating the snake's position.
The final code is compact (~100 lines) but complex due to extensive use of macros and bitwise operations.
