Open Source Mobile Operating Systems Game Development Frameworks

libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, macOS, Android, your browser and iOS. libGDX provides a well-tried and robust environment for rapid prototyping and fast iterations. libGDX does not force a specific design or coding style on you; it rather gives you the freedom to create a game the way you prefer. Publish your games on Windows, macOS, Linux (including the RPi!), Android, iOS, and HTML5, all with the same code base. libGDX comes with batteries included. Write 2D or 3D games and let libGDX worry about low-level details. Heavy emphasis is put on avoiding garbage collection for ART/JavaScript by careful API design and the use of custom collections. libGDX is a well proven and reliable framework with a sound base and documentation. Furthermore, there are plenty of games built on top of libGDX, many of which are open source.

raylib is highly inspired by Borland BGI graphics lib and by XNA framework. Do you want to see all functions available in raylib? Check raylib cheatsheet. raylib is a programming library to enjoy videogames programming; no fancy interface, no visual helpers, no auto-debugging, just coding in the most pure spartan-programmers way. raylib has received several recognitions in the last years and many people have written about the library. Here there are the main awards received from Google and Epic Games. raylib supports multiple target platforms, it has been tested in the following platforms but, technically, any platform that supports C language and OpenGL graphics is valid for raylib or can be very easily ported to. raylib can be combined with several extra libraries for additional functionality, some of those libraries are already used internally while others are provided for user integration, most of these libraries are single-file header-only with no external dependencies.

Phaser is a fast, free, and fun open source HTML5 game framework that offers WebGL and Canvas rendering across desktop and mobile web browsers. Games can be compiled to iOS, Android and native apps by using 3rd party tools. You can use JavaScript or TypeScript for development. You can support the developers on their Patreon. https://www.patreon.com/photonstorm

INSTEAD was designed to interpret the games that are the mix of visual novels, text quests and classical 90'ss quests.

Orx is a portable, lightweight, plugin-based, data-driven and extremely easy to use 2D-oriented game engine. As orx is data driven, it allows users to create games with a small number of lines of code and reduces drastically the development time.

UniRx (Reactive Extensions for Unity) is a reimplementation of the .NET Reactive Extensions. The Official Rx implementation is great but doesn't work on Unity and has issues with iOS IL2CPP compatibility. This library fixes those issues and adds some specific utilities for Unity. Supported platforms are PC/Mac/Android/iOS/WebGL/WindowsStore/etc and the library. Ordinarily, Network operations in Unity require the use of WWW and Coroutine. Rx cures that kind of "asynchronous blues". Rx is a library for composing asynchronous and event-based programs using observable collections and LINQ-style query operators. The game loop (every Update, OnCollisionEnter, etc), sensor data (Kinect, Leap Motion, VR Input, etc.) are all types of events. Rx represents events as reactive sequences which are both easily composable and support time-based operations by using LINQ query operators.

Asphyre, also known as Platform eXtended Library, is a cross-platform framework for developing video games and scientific applications in Delphi, and FreePascal/Lazarus. The framework provides facilities for real-time rendering of graphics (using DirectX, OpenGL or Software Renderer), text output, mathematics (including vectors and matrices) and networking communication, among other features. It also supports singleboard devices such as Raspberry PI, Intel Galileo, BeagleBone Black and others with features like GPIO, SPI, I2C and so on, along with external displays, sensors and other peripheral devices.

Ethanon is a 2D game engine focused on the recent video cards for hardware acceleration and shader effects. The engine provides high-quality light an shadow effects with an easy visual interface and a simple and direct scripting system.

Mokoi is a Game Creation Tool. Mokoi Games are platform neutral, if a compatible player is available for OS or Device, you can play games with no troubles. We're also have projects to help with creating and sharing platform neutral games.

Gamine is a 3D game engine for Android devices.

A Cross Platform 2d Rpg Game Engine for mobile and Console.

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.

CrossBrowdy is a free and open-source JavaScript framework that allows to create multimedia apps, emulators, game engines and games that will be compatible with any device. Any software developed with CrossBrowdy should be able to be used in any JavaScript compatible web client (including browser plug-in, add-on, extension, app...) which supports "document.getElementById". This framework allows any developer to manage easier many different things, such as audio (with Flash fallback, audio pool, etc.), canvas (with DHTML, VML, Flash or Silverlight fallbacks), screen, mouse, keyboard, gamepads, sockets (including PHP proxy fallback), XHR / AJAX (with PHP proxy for cross-domain requests), device sensors (compass / magnetometer, gyroscope, accelerometer, light sensor, proximity sensor...) and many more.

Magic Lantern is a framework for developing multimedia applications. It is designed to be a cross-platform solution for multiple targets such as desktops, game consoles, mobile devices and set-top boxes.

SDL adaptation for Symbian. The project has been there nearly ten years, but at last I get moved it into SourceForge as planned long ago.

Open Game Engine 2D is a full features and cross-platform 2D game engine. It aims to help developers to create 2D games with only flat files (such as ini and script files), so that games could be written once and played under any platform supported. This engine is a pure 2D game engine written in C/C++. It is base on SDL and AngelScript. So, it also aims to run in any platform supported by SDL and AngelScript, such as Windows, Linux, MacOS, iPhone, Android, Windows Phone, Symbian, NDS, PSP... But, in current version, the engine only supports the following platforms: Windows, Linux, MacOS, Windows Mobile, Android, iPhone.

My take mini sdk libs for creating the 2048 game in C#. Suitable for any engine from console app to Unity game. Only 2048 game logic. A very simple customizable core for initialization game with params.

A small project I did to try and program for Android. The program is written in Java with NetBeans. You can control a character with the touchscreen, the character will walk towards the point you are holding your finger on. Maybe I can use this to make something more interesting later, project is dead right not. But I want somewhere to save my sourcecode. http://www.youtube.com/watch?v=yYk1kpMlyTU&feature=channel_video_title

C-Lesh is a game programming language for 2D games - mainly arcade and platform games. When combined with the Super Mario World (SMW) engine you can create awesome 2D platform games like Super Mario World. This language evolved from a "clone" of TI-BASIC which I began developing when I was having memory (segmentation fault) bugs with C. C-Lesh lacks memory allocation and destruction. There is no need to use pointers and you can never get memory leaks or program crashes caused by memory leaks. As C-Lesh is somewhat primitive you may like it if you are into C. I'd say its a step up from C for 2D games. Everything is set - all you need is a sprite sheet and some programming knowledge.
