I haven’t checked out the animation editor in Unity, but I understand it is not (yet) available in Unity iPhone. Is there an ETA for this feature in the iPhone version?
Would it be possible to export the animation (through editor scripts or even at runtime) out of Unity, and then import them into Unity iPhone somehow? Maybe save the animations as xml or something, and parse them with code?
I only tested it with one simple moving cube, and then importing the project entirely in Unity iPhone, but just copying the .anim files will probably work just as well.
