MRubyD is a new virtual machine for mruby, designed specifically to integrate with C# environments, particularly targeting game development. The implementation in pure C# opens up possibilities for developers looking to leverage mruby's light and efficient scripting capabilities without having to rely on native C extensions. This could potentially lead to smoother scripting experiences in game engines that predominantly utilize C#, such as Unity and MonoGame. The emphasis on seamless integration suggests that MRubyD could facilitate easier scripting for game developers, especially in scenarios where performance and memory efficiency are critical.
