CPong

Pong, in C! A simple game, simple to play, simple to code.

This is mainly a practice project because I want to work on bigger projects (like a 3D graphics engine) and I think it's only appropriate to have built a simple 2D game with no engine before that.

Controls:

Player 1 (left), use either:

• W and S on the keyboard,
• DPAD_UP and DPAD_DOWN or
• the left analog stick on the controller

Player 2 (right), use either:

• ARROW_UP and ARROW_DOWN on the keyboard,
• GAMEPAD_Y and GAMEPAD_A or
• the right analog stick on the controller

what it taught me:

• programming a minimal application with only the C runtime library and the WIN32 API
• writing a simple software renderer that writes to a bitmap in RAM and blits that to the window
• normalizing coordinates for positions independent of buffer or screen size
• writing simple collision checks
• utilizing delta time and velocities to keep gameplay speed consistent, no matter the hardware
• getting and processing player input (both polling & interrupt-based, for controller & keyboard)
• unifying input so controller and keyboard can be used at the same time
• finding and loading a library via GetProcAddress() instead of linking to a .dll file after compilation
• using multi-line C macros and the _Pragma() replacement for #pragma

future plans:

• simulating a 7-segment display for the current score
• sound... possibly
• main/pause menu, start & restart games
• abstracting platform layer and porting to X11
