Hi
I have an app that uses player callbacks and I am now using LC 9.6 to work on
it and the callbacks work fine.
The callbacks, duration, currentTime and other movie time properties are in
timescale which is intervals/second as you said.
I just created a small stack and did a basic test of callbacks and it worked.
-create a new stack
-drag a player to the card
-drag a single line field to the card
-put the following code in the card's script
---------------
local sMovieScale
on mouseup
put the timescale of player 1 into sMovieScale
set the callbacks of player 1 to (sMovieScale * 0), "secondcount" & CR & \
(sMovieScale * 1), "secondcount" & CR & \
(sMovieScale * 2), "secondcount" & CR & \
(sMovieScale * 3), "secondcount"
end mouseup
on secondcount pCallbackTime
put (pCallbackTime / sMovieScale) && "seconds" into field 1
end secondcount
---------------------
- click on the card to set the callbacks
- play the movie to see if the seconds are displayed in the field.
See if that works.
If it does then maybe it is something with how you create your callback list.
You can see if the callbacks are actually set by with the line ‘ in the message
box
put the callbacks of player “yourPlayer
