Audio Looping(again :I )?

[Eamonn]

I asked this a while ago, but got no help on the subject. I'm working on a game called 'Mr. BallGuy', and I have a soundtrack playing during gameplay. This works well, but the audio does not loop. Here is a sample piece of code from the game:

Code: Select all

function love.load()
    song = love.audio.newSource('/songs/song.mp3')
    song:setLooping(true)
end

function love.update(dt)
    song:play()
end

This causes 2 problems:
1) The audio plays twice as fast
2) The audio doesn't loop

When I asked this before, the only reply said it was all right when it obviously isn't. The audio does not loop and I cannot for the life of me figure out why! If you know, please help! Is it another bug (like the audio crashing bug) in LÖVE 0.8.0?

Thanks! Any help is appreciated!

Try converting the mp3 to ogg. I guess löve has problems with the mp3 format sometimes.
edit: also I'm not sure if there is a problem with calling the :play() method everytime in the update loop.

I've tried converting the mp3 to an ogg but no luck

Thanks for the reply none the less

Good, so for me exactly the same code you use work on my computer. ( using a .ogg )
If your music file is fine I really had no clue why this shouldn't work.

LÖVE 0.7.2 had problems with mp3. This has been fixed.

The mp3 format requires special metadata to mark the exact sample where the audio ends. If there isn't, you may hear a click at the end of the track, but this should not stop it from looping.

Yes, you should not call play that often. Only call it if you mean to change the playing state or OpenAL (the library LÖVE uses for audio) throws a weird, unexpected error and LÖVE 0.8.0 goes into a long loop. This has been fixed for the next version.

Can you upload an example? It works as expected with my files.

I tested it again and I've found following:
I have a .ogg file with a short sound ( ~1,5esc ). I used this code:

Code: Select all

function love.load()
    song = love.audio.newSource('song.ogg')
    song:setLooping(true)
end

function love.update(dt)
    song:play()	
end

After ~ 15 loops the sound stopped. But when calling the Play() method just once like this :

Code: Select all

function love.load()
    song = love.audio.newSource('song.ogg')
    song:setLooping(true)
    song:play()
end

Then the problem does not occur. I guess there is some kind of overflow while calling the play() method to often.
So you should try to call play() just once when you want to change the music state ( as boolsheet said ).
You could do so in the love.load or alternatively in the update i.e in a if loop which is only called once when the game starts.

This problem WOULD fix the issue, but the song HAS TO PLAY DURING GAMEPLAY and not the start menu. BTW I got it working! I called it like 10 other times in love.update()

Then you call song:play() when the game proper starts, instead of in love.load(). You know, right next to state = "game" or whatever you use.
