To a lesser degree, it is also best to avoid hardwiring sprite numbers as well. A number of scripting techniques can offer the functionality you wish, while still remaining general enough for later transport or reuse. The following Cast Script goes into the spinner control itself.
All graphics are the same size and are named as above.
If they roll off the button then the spinner de-highlights and the numbers don't change. This is a safe assumption in this example, as we put the numbers there ourselves. There is no puppetry here, as the changes to the spinner graphics are not intended to persist across multiple frames.
