about

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

raylib is highly inspired by Borland BGI graphics lib (more specifically WinBGI) and by XNA framework. Allegro and SDL have also been analyzed for reference.

history

I've developed videogames for some years and last year I had to taught videogames development to young people with artistic profile, most of them had never written a single line of code.

I started with C language basis and, after searching for the most simple and easy-to-use library to teach videogames programming, I found WinBGI; it was great and it worked very well with students, in just a couple of weeks that people that had never written a single line of code were able to program (and understand) a simple PONG and some of them even a BREAKOUT!

But WinBGI was not the clearer and most organized lib. There were a lot of things I found useless and confusing and some function names were not clear enough for most of the students; not to mention points like no transparencies support or no hardware acceleration.

So, I decided to create my own lib, hardware accelerated, clear function names, quite organized, well structured, plain C coding and, the most important, primarily intended to LEARN videogames programming.

I've coded quite a lot in C# and XNA and I really love it (in fact, my students learn C# with XNA after C), so, I decided to use C# language notation and XNA naming conventions. That way, students can jump from raylib to XNA (or MonoGame) extremely easily.

raylib started as a weekend project and after three months of hard work, here it is the first version.

Enjoy it.

features

• Written in plain C code (C99)
• Uses C# PascalCase/camelCase notation
• Hardware accelerated using OpenGL 1.1
• Transparencies support (RGBA Colors)
• Custom color palette for better use on white background
• Basic 3D Support (camera, basic models, OBJ models, etc)
• Powerful Text module with SpriteFonts support

raylib uses on its core module the outstanding GLFW3 library. The best option by far I found for window/context and input management (clean, focused, great license, well documented, modern, ...).

raylib is licensed under a zlib/libpng license like GLFW3. View LICENSE.

tool requirements

raylib has been developed using exclusively two tools:

• Notepad++ (text editor) - http://notepad-plus-plus.org/
• MinGW (GCC compiler) - http://www.mingw.org/
  

Those are the tools I recommend to develop with raylib, in fact, those are the tools my students use. I believe those are the best tools to train spartan-programmers.

Someone could argue about debugging. raylib is a library intended for learning and I think C it's a clear enough language to allow writing small-mid size programs with a printf-based debugging. All raylib examples have also been written this way.

building

raylib could be build with the following command lines (Using GCC compiler):

cd raylib/src
gcc -c core.c -std=c99 -Wall
gcc -c shapes.c -std=c99 -Wall
gcc -c textures.c -std=c99 -Wall
gcc -c stb_image.c -std=c99 -Wall
gcc -c text.c -std=c99 -Wall
gcc -c models.c -std=c99 -Wall
gcc -c vector3.c -std=c99 -Wall
gcc -c audio.c -std=c99 -Wall
gcc -c utils.c -std=c99 -Wall
ar rcs raylib.a core.o shapes.o textures.o stb_image.o text.o models.o vector3.o utils.o audio.o

To compile examples, make sure raylib.h is placed in include path and libraries raylib (libraylib.a) and glfw3 (libglfw3.a) are placed in the libraries path. It's also recommended to link with file icon.o for fancy raylib icon usage.

cd raylib/examples
gcc -o test_code.exe test_code.c icon.o -lraylib -lglfw3 -lopengl32 -lgdi32 -std=c99 -Wl,--subsystem,windows
