If you want the GIF to stop playing when it reaches the last frame, why
wouldn't you set the repeatCount to 1?
If your GIF can play multiple times through (repeatCount = -1), then I
believe the only way you can track its frames is to poll it, with a
frequency that slightly exceeds its frame delay. Try running a loop while
the GIF is playing, maybe something like:
# GIF WITH 10 MS FRAME DELAY
on mouseUp
set the repeatCount of img "myGif" to -1
trackPlayback
end mouseUp
on trackPlayback
if the currentFrame of img "myGif" > (the frameCount of img "myGif" - 1)
then
set the repeatCount of img "myGif" to 0
set the currentFrame of img "myGif" to the frameCount of img "myGif"
-- just to be sure
exit trackPlayback
end if
send "trackPlayback" to me in 8 millisecs
end trackPlayback
