Open Source JavaScript Game Development Frameworks

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.

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.

We are in the process of creating a open source persistent browser based web game (PBBG) framework which will have all the features to get you started and let you start developing your unique features without having to write all the basics. We have taken a modular approach, you can use only the modules you want. If you wanted just a forum you could enable only the core, user and forum modules. We are building our framework using Kohana which is an open source, object oriented (H)MVC web framework built using PHP5 by a team of volunteers that aims to be swift, secure, and small. We are using Kohana 3.3 You can view a demo at http://demo.modulargaming.com If you have any questions, bugs or feature requests feel free to post them on the issue tracker at GitHub. https://www.github.com/modulargaming/modulargaming Licensed under a BSD license. Modular Gaming can be used legally for any open source, commercial, or personal project.
