Cocos2d-x vs jMonkeyEngine

Cocos2d-x is a free, open-source C++ framework for building games, apps, and other interactive GUI programs. Developers can publish from one codebase to mobile, desktop, web, and console targets, using C++ or JavaScript and Lua bindings. The product page lists OpenGL ES 2.0 and Metal for graphics rendering and says Lua or JavaScript can be used for game hot updates. Its maker describes the C++ core as lightweight and optimized for devices including low-end Android systems. The community maintains the framework under the MIT license. The download page says version 4.0 uses CMake for all platforms, supports Metal on iOS and macOS, and removes the H5 engine and JSB. The product page lists version 3.17 support for iOS 8.0 and later, Android 3.0 and later, Windows 7/8.1/10, macOS 10.9 and later, and standard HTML5 browsers. Developer resources include documentation, tutorials, demos, an API reference, and forums.

jMonkeyEngine is a free, open-source Java game engine for developers. It targets Windows, macOS, Linux, Android, and iOS, with mobile export and multiplayer foundations. Rendering includes a GLES 3.0 backend and direct OpenGL support from versions 3.2 through 4.5. Java 11 through Java 21, Gradle builds, JVM tooling, and direct Java-library use are listed. Networking foundations cover TCP, UDP, RPC, and synchronization patterns. Physics options include rigid-body, soft-body, and vehicle simulation through Bullet, Box2D, or Jolt Physics integration. Graphics features include PBR, custom materials and shaders, bloom, FXAA, SSAO, and tone mapping. A glTF workflow is described for moving Blender materials, lighting choices, and scene setup. The BSD 3-Clause License includes no runtime fees, royalties, splash-screen requirement, or requirement to mention the engine. Setup uses an initializer, NetBeans-based SDK, or direct Java-library configuration. SDK integrations are maintained separately and may lag engine features.
