Thanks guys. Unnatural20, yup, that about covers it. A0Nasser, yeah that's what I need to do, but programmatically by the app.
Somebody, you nailed it. I thought it was asking a bit much but folks here have done staggering things. Maybe I'll get by with just using big animated gifs, since I only need one to be loaded at any time. But that brings me back to another problem: C2 will do the animated gif splitting when you drag and drop the file onto the editor, but it seems like the runtime is not able to do the same trick. Am I understanding that right? If I am then what I now need is some code to turn an animated gif into sprite frames so that the runtime can treat them just like any other sprite (albeit huge)?
