I’ve ported IceCream to iOS (iPhone and iPad) using Monotouch and XnaTouch. Here’s a video of the CompositeEntity shown in my last post, in action: http://www.youtube.com/watch?v=E4D7TYtb_U8
All the XML scene code can be imported as is, and everything *should* work as on Xbox/PC except PostProcessAnimations.
They are still some stuff to fix with XnaTouch so I won’t make a release at the moment, but I will merge the SVN code soon with the changes. The code base will stay unique for all devices.
