cppsnek - A Simple Snake Game in C++ with SFML

Snake in C++17 ; uses SFML ; the snake is on fucking crack ; it moves like a fucking mig21

Features

• Classic Snake gameplay with grid-based movement
• Score tracking and milestone celebrations
• Programmatically generated sound effects (no external audio files needed)
• Simple pixel-art style graphics
• Responsive controls (WASD or arrow keys)
• Adjustable game speed that increases with score
• Visual grid overlay
• Pause/resume functionality (Space key)

Technical Details

• Language: C++17
• Libraries:
  • SFML 2.5+ (Graphics, Window, System, Audio modules)
• Pattern: Object-oriented design with separate classes for game logic, rendering, and sound
• Notable Techniques:
  • Programmatic sound generation
  • Pixel pattern-based sprite creation
  • Vertex arrays for grid rendering
  • State management for game flow

Building the Project

Requirements

• CMake (version 3.10+)
• SFML development libraries (libsfml-graphics, libsfml-window, libsfml-system, libsfml-audio)
• C++17 compatible compiler

Build Steps

mkdir build && cd build
cmake ..
make

Running

./cppsnek

Controls

• W - Move Up
• A - Move Left
• S - Move Down
• D - Move Right
• Space - Pause/Resume game

Key classes:

• Game: Main game loop and state management
• SoundManager: Handles all audio generation and playback
• NumericSprite: Creates sprites from numeric patterns
• SnakeSegment: Simple struct for snake body parts

Customization

You can easily modify:

• Game speed by changing the speed initial value in Game constructor
• Grid appearance by modifying the createGrid() method
• Snake and fruit visuals by editing the pattern arrays
• Sound characteristics in the SoundManager class

Known Issues/Limitations

• Sound generation is CPU-intensive during initialization
• No proper game menu or start screen
• High scores aren't persisted between sessions
• Theme song generation is currently commented out

Learning Objectives

This project demonstrates:

1. SFML basics (window management, rendering, input handling)
2. Game loop implementation
3. Procedural audio generation
4. Simple collision detection
5. State management in games
6. Object-oriented game design
