AntTweakBar is a small and easy-to-use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL or DirectX based graphic programs to interactively tweak them. Program variables can be linked to a graphical control that allows users to modify them. Programmers are not required to design the graphical interface by providing coordinates or by using a visual UI editor. Controls are automatically organized following an optional given hierarchy.
HappyHTTP is a simple C++ library for issuing HTTP requests and processing responses. It is simple to integrate: just drop in the .h and .cpp files. It has an easy-to-use interface, non-blocking operation (suitable for use in game update loops), and pipelining support (you can issue multiple requests without waiting for responses).
Xye is a puzzle game in which the objective is to get all the gems in each level. The mission is not as easy as it sounds: there are traps, monsters, and very hard puzzles everywhere. The player can interact with objects in the game in a lot of ways, and some of the objects can also interact with other objects.
Adime is a library for constructing Allegro GUI dialogs in a way similar to scanf(), using a format string. Other features include a (customizable) 3d look and feel, 3d versions of some of Allegro's GUI procs, complete help in many formats (HTML, txt, chm, texinfo, man, devhelp, and RTF), and four example programs. Adime can currently be compiled on Linux, Windows/MinGW32, Windows/Borland C++, Windows/MSVC, DOS/DJGPP, DOS/Watcom, Apple MacOS X, and QNX.
