I have an idea for a free-form button animation I'd like to do, but I only want one of the states (mouseover) to be animated. I've reviewed the UIS2 skinning tutorial section on animated buttons, but it is more vague than I'd like.

How do you construct the source image?

If the animation has say 4 frames, would each button state require 4 tiles? Arrayed left-to-right, start-to-finish?

Does Animation/Frame Count refer to the total number of tiles in the image or just the number of tiles which constitute the animation cycle? And if the normal and pressed states are to be 'static', would they require 4 identical tiles each?

If yes, would the same number of tiles be required for the inactive window button states (uis2)?

Does WB expect to see an image with (e.g.) 4 tiles for each button state if you set the Animation/Frame Count to 4? Or do you only need the additional 'frames' placed in between the Active Pressed tile and the Inactive Normal tile, assuming only the Mouseover state is animated?

If you set the Frame Count to 4 and the Animation Rate to 250ms, will you get a repeating animation at 4 frames per second (while in that 'state') or just a single cycle?

Are any other settings besides Frame Count and Animation Rate needed to enable animation for a button?

Sorry there's so dang many questions in there, but inquiring minds want to know.

TIA.
