Architecture

The game is built around several key components:

• Position: Represents coordinates on the board
• Direction: Manages movement directions
• Snake: Handles snake logic, movement, and collision detection
• Fruit: Manages fruit spawning and point values
• Board: Manages game boundaries and fruit placement
• Input: Handles keyboard input in non-blocking mode

Configuration

Game parameters can be modified in include/Constants.hpp:

constexpr int BOARD_WIDTH = 30;
constexpr int BOARD_HEIGHT = 20;
constexpr int FRUIT_POINTS = 10;
