Classic Pong built entirely from scratch in raw C++ — no game engine, no graphics API, just direct pixel manipulation via Win32 GDI. Supports single-player against an AI opponent and local two-player multiplayer, with 3D positional audio for spatialized sound effects. Every system (renderer, game loop, collision detection, entity architecture, menu state machine) is hand-rolled, organized into distinct platform, framework, and game logic layers.
[key features]
- Pure software rendering: direct pixel buffer writes, no OpenGL/DirectX/Vulkan
- 3D positional audio via OpenAL for spatialized gameplay sound effects
- Custom bitmap text rendering without font libraries
- Delta-timed game loop with AABB collision, paddle-velocity transfer, and state-driven pause
- Adaptive AI opponent with anti-stalemate logic and local two-player multiplayer
[implementation details]
Rendering & Platform
- Win32 platform layer handling window creation, input, and frame timing with delta-time accumulation
- Software rasterizer: VirtualAlloc framebuffer blitted to screen via GDI StretchDIBits each frame
Game Architecture
- Entity system with base class and Ball/Paddle specializations; state machine managing menu and gameplay transitions
- Audio subsystem wrapping OpenAL with layered abstractions (device, library, player) for source positioning
- Adaptive AI with speed modulation based on ball direction and deliberate pattern-breaking to prevent stalemates
