Cocos2dx

Cocos2d-x is a cross-platform, open-source game development framework for building 2D games. It is the C++ port of the cocos2d family and was released by Chukong Technologies with contributions from the open-source community. The framework is released under the MIT license and emphasizes performance and portability, enabling developers to write code once in C++ and deploy to multiple platforms.

The engine uses a scene graph architecture built around Node, Scene, Layer, and Sprite classes. Core features include animations and actions, scheduling and timing, particle effects, audio support, and physics integration with Box2D or Chipmunk. Rendering supports texture atlases and sprite sheets to optimize performance, and it provides a modular set of subsystems for input, UI, and rendering.

Cocos2d-x includes scripting bindings in Lua and JavaScript, allowing teams to implement game logic while maintaining a C++ core. It targets major mobile platforms such as iOS and Android, as well as desktop platforms including Windows, macOS, and Linux. The project is maintained by Chukong Technologies along with an active community, with ongoing releases across major version lines.

Cocos2d-x is distinct from Cocos Creator, which is a separate game development environment and editor built around the cocos2d-x engine, focusing on a component-based workflow and visual tools.
