Hi everyone! I'm creator of brand new opensource .NET based 2D game engine called Vortex2D.NET (http://vortex2d.codeplex.com). It is written with C++/CLI and C# and uses Direct3D9 for hardware graphics acceleration. The primary aim of this project is to deliver simple, intuitive, easy to use but powerful tools for creating 2D games of any type for wide specter of developers: from beginners to professionals. Key features of engine: - Rich sprite drawing functionality - Built-in HLSL/assembly shader support for advanced effects - Great performance - Good set of helper classes to organize game flow (scenes, states, planning timeline etc) - Flexible particle system framework with Visual Particle Editor for default implementation - Stack based world transformations (translating, rotating, scaling) - Easy-to-use multitexturing - XML-based content loading (in progress) Currently engine in alpha but first beta release is scheduled on May 31. There are few things are worth to try: - Gameplay demo of Pacman with cool particle and shader effects - Visual Particle Editor. It is in development process but already could be a god toy. All downloads are available on home page of http://vortex2d.codeplex.com/ I really hope for your support and will very happy to get comments, feedbacks and advices.
