Quick question: player object callbacks still working?

[Martin Koob]

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
