Cocos2d-x is a C++ cross-platform port of the popular iOS gaming framework Cocos2d. It was first released in November 2010, and bought in 2011 by Chukong Technologies, a Beijing-based mobile gaming company. Nevertheless, it is still maintained by an active community of more than 400,000 developers worldwide, including Ricardo Quesada, the creator of the original Cocos2d iPhone engine.

This framework encapsulates all the game details, such as sound, music, physics, user inputs, sprites, scenes, and transitions, so the developer will only have to focus on the game logic rather than re-inventing the wheel.
