I'm trying to work on the graphical aspect of a game I'm designing in Xcode using sprite kit, and I was wondering if anyone knows how the main character sprites in games like Leo's Fortune and Badland are animated when touched (they fluff up and morph very fluently). How could this be accomplished and what compatible file type could execute this fluent animation? Is .flv compatible with Xcode? I would rather not change the texture in a keyframe sort of way with a .png because that would require a lot of textures at a high texture switching rate.
Any advice on this matter would be greatly appreciated
Thanks
