Building the Game

Prerequisites

• CMake (3.10 or higher)
• C++ Compiler with C++17 support:
  • Visual Studio 2019/2022 (Windows)
  • GCC 7+ (Linux)
  • Clang 6+ (macOS)

Build Steps

1. Clone the repository:

   git clone <repository-url>
   cd "SpaceWar Game in CPP"

2. Generate build files:

   cmake -S . -B build

3. Build the project:

   cmake --build build --config Release

4. Run the game:

   • The executable will be in build/Release/
   • Make sure the resources/ folder is in the same directory as the executable

Alternative Build (Visual Studio)

For Visual Studio users:

cmake -S . -B build -G "Visual Studio 17 2022"
cmake --build build --config Release

Controls

• Movement: WASD or Arrow Keys
• Aim: Mouse cursor
• Shoot: Left Mouse Button
• Exit: ESC key

Game Mechanics

Player

• Move freely in 2D space
• Aim with mouse cursor
• Shoot projectiles at enemies
• Health regenerates slowly over time
• Game over when health reaches zero

Enemies

• Spawn randomly around the player
• Different ship types with varying:
  • Speed and maneuverability
  • Fire rate and bullet speed
  • Health and durability
• AI that pursues and attacks the player
• Despawn when too far from player

Combat

• Projectile-based combat system
• Collision detection between bullets and ships
• Health system for both player and enemies
• Audio feedback for shooting and impacts

Asset Credits

• Fonts: CommodorePixeled.ttf
• Graphics: Custom space ship sprites and UI elements
• Audio: Sound effects for shooting and ambient audio

Development Notes

This project demonstrates:

• Modern C++ game development practices
• OpenGL 2D rendering techniques
• Entity-component-like architecture
• Audio integration in games
• CMake build system setup
• Cross-platform game development
