Greetings All
I'm trying to control how a text file with a list of audio files in it
are read/played.
Example:
I have a text file which is read and plays several audio files one
right after the other till the end. I would like to have it read/play
the text file list in reverse, forward, or loop play on the current
file.
So if I have a text file with.
one.wav,
two.wav
three.wave
When a button is clicked for Forward it reads the text file and plays
the audio files like:
one.wav
two.wav
three.wav
When a button is clicked for Reverse it reads the text file and plays
the audio files like:
three.wav
two.wav
one.wav
When a button is clicked for Loop it reads the text file and plays
the audio files like:
one.wav
two.wav
two.wav
two.wav .... until I cancel the loop or hit another button to go
forward or reverse
I've gotten the buttons to work as a selection but I'm having issues
in getting the text list to change directions and loop. I was
thinking of using a list to read in all the lines in the text file but
I wasn't sure how to get the list to read/play in the forward,
reverse, and loop options. Is their another way I should be trying to
do this? I've attached what I have so far.
Thanks
To loop the current file you need to know where in the playlist you are.
[textfile] doesn't really have this information ( [msgfile] in zexy does
though so you might want to look at that ). Or you can make a counter to
keep track of where you are so you can then loop the track, or reverse
the playback. See attached patch.
