AndEngine
Free Android 2D OpenGL Game Engine
AndEngine is a Java-based, open-source 2D game engine for Android, designed to make mobile game development easier by wrapping OpenGL (GLES) under a higher-level API. It abstracts much of the complexity of directly using OpenGL, letting developers more quickly build games with sprites, tilemaps, physics (via extensions), animations, and input handling, all within the Android ecosystem. Because it's tailored for Android, AndEngine integrates with typical Android project structure and lifecycle, although historically it was more aligned with Eclipse — meaning some adaptation might be needed for modern Android Studio projects. It enjoys a substantial community, many forks and extensions (for physics, tilemaps, multiplayer, live wallpapers, etc.), which increases its versatility — from simple casual games to more feature-rich 2D titles. -

NettyGameServer
A mobile game distributed server implemented using netty4.X
A mobile game distributed server implemented using netty4.X, supports tcp, udp, http, websocket links, uses protobuf custom protocol stack for network communication, supports rpc remote calls, uses mybatis3 to support db storage sub-database sub-table, supports asynchronous mysql Storage, update the reids cache synchronously when the db is saved. Use the ExcelToCode project to generate java classes and json data dictionaries from excel data, and DictService directly reads json to reduce part of the data dictionary code. Use the game-executor project to increase the asynchronous event global service in the game, support event sharding, and balance asynchronous execution event logic. Use netty's proxy mode to increase gateway proxy forwarding. -

Android Game Engine
Multi-threaded game engine for Android
AGE is a multi-threaded game engine for Android with OpenGL ES2 shader-based rendering. In-depth GL knowledge isn't necessary to start; use the OBJ loader to import models from Blender and elsewhere, attach textures, and start rendering! Threads run different activities, e.g. initialization, framerate, timer, game cycle. Apartment model with message passing. The drawing cycle is inverted from typical game loops. Framerate has a dedicated timer, and SurfaceView is in on-demand rendering mode. Game Objects (GOs) opt-in to services by implementing the "marker" interface for each one it wants. GOs enter the system via Install Pipeline, an asynchronous "standard" implementation that keys on the marker interfaces and performs the "protocol" for that marker. There are also Event and Uninstall pipelines. Reference by name is encouraged. A trip through the pipeline includes a Bind Name List; allows GO to connect to interfaces in other GOs on the other End. -
