PONG 2026

A deliberately over engineered Pong clone in Odin with raylib.

Retro line-based graphics with a CRT post-processing shader.

Why Over-Engineered?

While the game could have been done in a single file, the goal was to structure the project like a small production game instead:

Manager-per-subsystem: audio, input, event, level, particle, and scene managers, each in its own file
Event system: decoupled communication between systems (event_manager.odin) instead of direct calls
Scene management: state/scene stack for menus, gameplay, etc. (scene_manager.odin)
Entity layer: shared base entity with ball, player, and opponent specializations
Input abstraction: keyboard and gamepad behind one interface
Data-driven assets: audio and shaders loaded from assets/, not embedded

The idea behind breaking it into systems is so that it can help build my foundations into more complex games.

Features

Single-player vs AI opponent
CRT fragment shader (assets/shaders/crt.fs)
Particle effects, sound effects, music
Gamepad support via SDL controller mappings

Controls

Action	Keyboard	Gamepad
Move	W(up) S(down)	Left Joystick
Select	Enter	A button
Pause	Spacebar	Start button

Requirements

Please note, I have not built this on MacOs or Windows, only linux. While in theory if you have the odin compiler it should just work as there is no external libs besides those bundled with Odin.

Odin compiler (version dev-2026-10:e87445a58)
raylib (bundled with Odin as vendor:raylib)
GPU/driver with OpenGL 3.3 support (shader uses #version 330)

Build & Run

./build.sh          # see build.sh for flags and options
