You are off by 2 because setting the filename of a player also sends a
"playstopped" message. You'll need to bracket setting the filename with
"lock messages/unlock messages" commands to block the extra playstopped
message that gets sent.
But brace yourself. There is a discussion going on right now on the MC
list about playing files serially in a player. While the Rev IDE
receives the "playStopped" message just fine, standalones built for OS X
do not. It's a bug. If you are only building for Windows there's no
problem, since the bug is only in OS X.
My work-around involves including a calculation like this:
-- set the player filename, then:
put the duration of player "mp" into theDur
put (theDur/the timeScale of player 1) into theSecs
start player "mp"
send "movieStop" to me in theSecs seconds
And then replace your "playStopped" handler with a custom message
handler, like this:
on movieStop
global gCurrentMovie, gMovieTally
--if there is only one clip listed in fld "goodFiles", then stop:
if the number of lines in fld "goodFiles" = 1 then
set the hilitedline of fld "goodFiles" to empty
else -- line 2 or greater
get the hilitedline of fld "goodFiles"
if line it + 1 of fld "goodFiles" = empty then exit movieStop
set the hilitedline of fld "goodFiles" to it + 1
put line it of fld "goodFiles" into gCurrentMovie
set the filename of player "mp" to gCurrentMovie
set the currentTime of player "mp" to 0
put the duration of player "mp" into theDur
put (theDur/the timeScale of player 1) into theSecs
start player "mp"
send "movieStop" to me in theSecs seconds
end if
end movieStop
This is a kludgy workaround until the bug gets fixed.
