Hi all,
I've built an MP3 player to play songs while at work.
I decided to add a checkbox "Continuous play" to allow the songs to play one
after the other,
to the end of the list of songs.
To start the player, I double click on the first in the list (see "on
mouseDoubleUp" script below),
and it sets the player filename with the path and MP3 filename.
When it finishes playing that song, it should go to the next line in the
list and start playing that song.
I have a "on playStopped" script to handle that. But there's a problem with
it.
It skips a line and starts playing that song.
Here's the script for that:
on playStopped
local TotalLines, tLineNum, tCPlay, tSong
put the number of lines of fld "SongList" into TotalLines
put the hilitedLine of fld "SongList" into tLineNum
add 1 to tLineNum
put the hilited of btn "Continuous Play" into tCPlay
if tCPlay then
if tLineNum <= TotalLines then
set the hilitedLine of fld "SongList" to tLineNum
--PlaySong
put fld "MusicFolder" into MusicFolder
put the selectedText of fld "SongList" into tSong
replace tab with empty in tSong
set the fileName of player "Player" to MusicFolder & slash & tSong
set the currentTime of player "Player" to zero
start player "Player"
else
set the hilitedLine of fld "SongList" to 1
end if
end if
end playStopped
Here's the peculiar behavior:
When the LC engine gets to "set the filename of player...", the engine goes
back to the "on playStopped" line and executes from the top again.
When it gets to "set the fileName of player..." again, it continues on to
"start player...", then goes to "end playStopped", which it should do.
But then it goes to the line "set the currentTime..." line and then the next
line "start player...".
Sometimes when it is playing the song, there's no audio at all.
Here's the SongList field script to get the player started:
global MusicFolder
on mouseDoubleUp
local tSongTitle
put fld "MusicFolder" into MusicFolder
put the selectedText of me into tSongTitle
-- SongList field is set as a table.
-- First column is the MP3 filename and the 2nd column contains ".mp3"
-- This is for asthetics, so you don't see the .mp3 in the list.
replace tab with empty in tSongTitle
set the fileName of player "Player" to MusicFolder & slash & tSongTitle
set the currentTime of player "Player" to zero
start player "Player"
end mouseDoubleUp
How do I stop the "on playStopped" script from repeating itself and get it
to play without skipping a line?
Any and all help appreciated,
Mark Stuart
