The simplest way to make 2D games in C - Just ONE header file!

• ONE File - Just copy piper.h to your project
• Zero Dependencies - Everything embedded (Windowing, Graphics, Math, Audio, etc.)
• Instant Setup - Drop and code
• Full Featured - Everything you need for 2D games

Download piper.h and put it in your project folder. That's it!

Create main.c:

#define PIPER_IMPLEMENTATION  // Defines the implementation (do this in ONE file only)
#define RGFWDEF               // Required for windowing
#include "piper.h"

int main() {
    InitGame(800, 600, "My Game");
    
    while (!GameShouldClose()) {
        BeginFrame();
        
        ClearBackground(COLOR_BLACK);
        
        SetDrawColor(COLOR_GREEN);
        DrawCircle(400, 300, 50);
        
        EndFrame();
    }
    
    CloseGame();
    return 0;
}

gcc main.c -o game.exe -lgdi32 -lopengl32 -lwinmm
./game.exe

That's it! No build systems, no package managers, no dependency hell.

Everything you need for 2D games is built-in:

• Graphics

  • Shape drawing (rectangles, circles, triangles, polygons)
  • Texture loading & rendering (PNG, JPG, BMP, TGA)
  • Transformations (rotation, scaling, tinting)
  • 2D camera system

• Text

  • TrueType font rendering
  • Custom font loading
  • Text measurement

• Input

  • Keyboard (down, pressed, released states)
  • Mouse (position, buttons)

• Math

  • Full vector math library (linmath.h embedded)
  • Vector2/3/4 operations
  • Matrix transformations
  • Transform2D helpers

• Time

  • Delta time for frame-independence
  • Smooth 60 FPS rendering

• Tutorial - Step-by-step guide
• API Reference - Complete function docs
• Examples - Sample games

All use ONLY piper.h!

Other frameworks:

• ❌ Dozens of dependencies
• ❌ Complex build systems
• ❌ Hours of setup
• ❌ Version conflicts

Piper:

• ✅ One file
• ✅ Copy & paste
• ✅ 30 seconds to first game
• ✅ No dependency management

ClearBackground(MakeColor(20, 20, 40, 255));

SetDrawColor(COLOR_RED);
DrawCircle(400, 300, 50);

SetDrawColor(COLOR_YELLOW);
DrawRectangle(200, 150, 100, 75);

if (IsKeyDown(KEY_W)) playerY -= 200 * GetDeltaTime();
if (IsKeyPressed(KEY_SPACE)) Shoot();

int mx, my;
GetMousePosition(&mx, &my);
if (IsMouseButtonPressed(MOUSE_LEFT)) Click(mx, my);

Texture* player = LoadTexture("player.png");
DrawTexture(player, x, y);
DrawTextureEx(player, x, y, 64, 64, rotation, COLOR_WHITE);

Vector2 pos, vel;
Vector2Make(pos, 100, 100);
Vector2Make(vel, 5, 0);

vec2_add(pos, pos, vel);
float dist = Vector2Distance(pos, target);

Embedded Libraries:

• RGFW - Cross-platform windowing
• rlsw - Software renderer
• linmath.h - Linear algebra
• STB Image - Texture loading
• STB TrueType - Font rendering

All pre-integrated and tested - you don't need to know about any of this!
