(The AndEngine is developed based on the libGDX framework. It uses OpenGLES for graphics production. The underlying layer is written in C and implemented through JNI calls. Therefore, it is relatively efficient and powerful. It integrates the Box2D physics engine together, so it can achieve some messy physical effects. After Rokon (another Android 2D game engine) announced to stop updating, AndEngine became the most popular 2D game engine for Android. Compared with Libgdx engine: AndEngine has more game components and extended functions; And it can already support Chinese with tacit consent; The screen coordinate system is also more suitable for general Android drawing habits.)
