Cocos2d-x is an open source, flexible, and lightweight cross-platform game engine that has been providing developers with stable and mature solutions since 2011. The engine offers interfaces in C++, Lua, and JavaScript, supporting platforms such as iOS, Android, Windows, macOS, and HTML5 browsers like Chrome, Safari, and Internet Explorer. Built upon OpenGL ES 2.0 and Metal for graphics rendering, Cocos2d-x fully exploits the GPU performance of mobile devices while maintaining compatibility. Developers can utilize Lua or JavaScript scripting languages to perform hot updates to games, eliminating the need to send packages to app stores and wait for review. The engine's open-source capabilities allow for extensive customization, enabling game companies to develop their own game types and extensions, including combining their own 3D engines to solve 2D interface and UI problems. According to test data, Cocos2d-x version 3.x is compatible with 99.7% of Android devices in China.
