From: extranoob on
I have created a sprite xtra that does some drawing on the asset. During
playback, I need to know each time the asset has reached the ending of the
timeline (and/or beginning), if that makes sense.

I thought kMoaMmEvent_SpanEnd would be the answer, but it only fires when the
asset leaves the stage (I believe).
And kMoaMmEvent_SpanBegin fires when the asset first starts playing, not every
time it is restarted during playback.

Also, I have downloaded the development kit and found the documentation to be
lacking in details. Does anyone know of a good source of information for
developing more complicated Xtra's?

Thanks in advance.
