The animation engine in XNA is mostly complete now. It does multiframe symbols as well as nested animations. It also handles negative scales which Flash is fond of, and XNA not so much. The Box2D part is also working with nested animations, and there are some simple components in like Button with the different states. Next up is adding replacement markers. So for example if a flash symbol is exported as ‘$ship$’, the vector graphics will be replaced with a 3D model call ’ship’ at runtime. That model will then behave as a regular sprite or box2D element (so a 3D model that only moves in 2 dimensions, with 2D physics applied).

Here is a quick demo:

Going to L.A. for the week, but I should have time to finish up the first game with this (almost there).
