Classic Snake Game in C++

A console-based version of the timeless Snake game, developed using C++. This project serves as a great beginner-friendly example of game loop mechanics, input handling, and basic console manipulation in C++.

Features

• Classic Snake Mechanics: Eat the fruit (F) to grow your snake (o) and increase your score.
• Dynamic Score Keeping: Your score is displayed and updated in real-time.
• Infinite Walls: The snake can wrap around the screen, moving from one edge to the opposite.
• Collision Detection: The game ends if the snake's head (O) collides with its own body.
• Simple Controls: Easy-to-use keyboard controls for fluid movement.

Prerequisites

To compile and run this game, you will need:

• A C++ compiler (like G++, MinGW, or the compiler included with Visual Studio).
• A Windows operating system (due to the use of <windows.h> and <conio.h>).

How to Compile and Run

1. Open a terminal or command prompt.
2. Navigate to the directory where you saved the Snake Game (PF Project).cpp file.
3. Compile the code using your C++ compiler. For example, if you are using g++:

   g++ "Snake Game (PF Project).cpp" -o SnakeGame.exe

4. Run the game by executing the compiled file:

   ./SnakeGame.exe

How to Play

The goal is simple: guide the snake to eat as much fruit as possible without running into itself!

• Controls:

  • W - Move Up
  • A - Move Left
  • S - Move Down
  • D - Move Right
  • X - Exit the game at any time.

• Objective:

  • The snake (O is the head, o is the tail) follows your commands.
  • Each time you eat a fruit (F), the snake gets longer and your score increases by 10.
  • The game ends if the snake's head hits any part of its tail.

Code Overview

The logic is contained within a single C++ file and is organized into several key functions:

• setup(): Initializes all game variables, sets the snake's starting position, and places the first fruit.
• draw(): Renders the current state of the game to the console. It clears the screen and redraws the border, snake, fruit, and score for each frame.
• input(): Listens for keyboard presses to change the snake's direction or to exit the game.
• logic(): The core of the game. It updates the snake's position based on the current direction, checks for collisions with fruit or the snake's own tail, and updates the tail segments.
• main(): The main function that contains the game loop, which continuously calls the draw, input, and logic functions until the gameOver flag is set to true.

Future Improvements

This is a simple implementation, but it could be expanded with new features:

• High Score System: Save the highest score to a file so it persists between games.
• Difficulty Levels: Add options to increase the snake's speed.
• Obstacles: Add walls or other obstacles inside the play area.
• Power-ups: Introduce special fruits that have different effects (e.g., slow down time, shrink the snake).
• Cross-Platform Support: Refactor the code to remove Windows-specific libraries and allow it to run on macOS and Linux.
