🔧 Build Configurations

The project supports multiple build configurations:

• Debug – Includes debug symbols and no optimization (-g -O0)
• Release – Optimized build (-O3)

Build in release mode with:

ymk build release

🛠️ Development

Building from Source

# Debug build (default)
ymk build

# Release build
ymk build release

# Clean build
ymk clean

Project Configuration

Edit build.ymk to modify:

• C++ standard (cpp_std)
• Compiler flags
• Linked libraries
• Include/library directories

---

📦 Dependencies

Library	Purpose	Version
GLFW3	Window management	3.x
OpenGL/GLAD	Graphics rendering	4.0+
OpenAL	Audio system	1.x
GLM	Math operations	Latest
stb_image	Texture loading	-
tiny_obj_loader	Model loading	-

---

🎨 Graphics & Assets

• Shaders – Located in res/shaders/, includes vertex and fragment shaders for 3D rendering and UI
• Textures – Organized by category (Brick, Stone, Wood, Tiles, Doors, etc.)
• Models – OBJ format models with MTL materials
• Maps – Custom map definitions with collision data

---

🔊 Audio

The game uses OpenAL for spatial audio. Audio files are organized in res/audio/ by event type (death, impact, etc.).

---

🐛 Troubleshooting

Game won't start

• Ensure your GPU supports OpenGL 4.0+
• Check that all DLLs (glfw3dll, OpenAL32dll) are in the lib/ directory
• Verify the executable is in bin/snow_doom.exe

No sound

• Check that your audio device is connected
• Verify OpenAL is properly installed

Build errors

• Ensure C++20 compiler support (g++ --version)
• Verify ymk is installed and in your PATH
• Check that vendor libraries are up to date
