A single-tower defense game created with the Odin programming language, using Box2D for physics and Raylib for graphics.

This tower defense game features a single tower that must defend against waves of enemies approaching from all sides. The game demonstrates the integration between Box2D physics and Raylib rendering.

• Single tower with attack capabilities
• Multiple enemy types with different characteristics
• Physics-based movement and collisions using Box2D
• Real-time rendering with Raylib
• Score tracking and wave progression
• Debug mode to visualize physics bodies

• The tower automatically targets and fires at the closest enemy
• Enemies spawn from the edges of the screen and move toward the tower
• When enemies reach the tower, they damage it and reduce player lives
• The game ends when all lives are lost
• Waves become progressively more difficult with faster spawn rates and tougher enemies

• Enter: Start game from menu / Restart after game over
• F1: Toggle debug mode (shows physics bodies and debug information)
• ESC: Exit game

This game serves as a demonstration of how Raylib can render Box2D physics objects. The integration works as follows:

1. Physics System (Box2D)

   • Handles all collision detection and resolution
   • Manages object movement and forces
   • Maintains the physical state of all game entities

2. Rendering System (Raylib)

   • Translates physical positions to screen coordinates
   • Renders game objects based on their physical properties
   • Provides visual feedback for game state

3. Coordinate Conversion

   • Box2D uses a meter-based coordinate system
   • Raylib uses a pixel-based coordinate system
   • The PHYSICS_SCALE constant (30 pixels per meter) handles the conversion

• src/: Contains all source code files
  • main.odin: Entry point of the application
  • game/game.odin: Game logic and mechanics
  • physics/physics.odin: Box2D physics integration
  • renderer/renderer.odin: Raylib rendering of Box2D objects

• macOS operating system
• Odin programming language
• LLVM
• Xcode Command Line Tools
