raysan5/raylib

raylib is a simple and easy-to-use library to enjoy videogames programming.

raylib is highly inspired by Borland BGI graphics lib and by XNA framework and it's especially well suited for prototyping, tooling, graphical applications, embedded systems and education.

NOTE for ADVENTURERS: raylib is a programming library to enjoy videogames programming; no fancy interface, no visual helpers, no debug button... just coding in the most pure spartan-programmers way.

raylib presents some limitations by design for code simplicity. Some forks, alternatives, and samples are available to overcome most of them but it's up to the users to modify the library for their specific needs.

• Single window with single OpenGL context by default, no multi-window support
• Window resize and move stops the rendering loop on platforms supporting a window
• RenderTextures are flipped vertically, as provided by OpenGL, it's up to the user to draw them flipped to the screen
• Font rasterization has lower quality than alternatives using Freetype2, HarfBuzz or Slug
• Text drawing does not support RTL, ligatures or emojis

This is a basic raylib example, it creates a window and draws the text "Congrats! You created your first window!" in the middle of the screen. Check this example running live on web here.

#include "raylib.h"

int main(void)
{
    InitWindow(800, 450, "raylib example - basic window");

    while (!WindowShouldClose())
    {
        BeginDrawing();
            ClearBackground(RAYWHITE);
            DrawText("Congrats! You created your first window!", 190, 200, 20, LIGHTGRAY);
        EndDrawing();
    }

    CloseWindow();

    return 0;
}

raylib binary releases for Windows, Linux, macOS, Android and HTML5 are available at the Github Releases page.

raylib is also available via multiple package managers on multiple OS distributions.

raylib Wiki contains detailed instructions on building and usage on multiple platforms.

• Working on Windows
• Working on macOS
• Working on GNU Linux
• Working on Chrome OS
• Working on FreeBSD
• Working on Raspberry Pi
• Working for Android
• Working for Web (HTML5)
• Working anywhere with CMake

Note that the Wiki is open to edits, if you find some issues while building raylib for your target platform, feel free to edit the Wiki or open an issue related to it.

raylib has been developed on Windows platform using Notepad++ and MinGW GCC compiler but it can be used with other IDEs on multiple platforms.

Projects directory contains several ready-to-use project templates to build raylib and code examples with multiple IDEs.

Note that there are lots of IDEs supported, some of the provided templates could require some review, so please, if you find some issue with a template or you think they could be improved, feel free to send a PR or open a related issue.

raylib is designed to be learned using the examples as the main reference. There is no standard API documentation but there is a cheatsheet containing all the functions available in the library with a short description of each one; input parameters and result value names should be intuitive enough to understand how each function works.

Some additional documentation about raylib design can be found in raylib GitHub Wiki. Here are the relevant links:
