Ogg Vorbis playback and volume animation

[Peter Perhac]

Hello, I am having difficulties with looped sound playback and volume
animation. I tried to achieve a simple music fade-in effect by
animating the Fixed property passed to Sound.loop(volume) for volume
but this stops the looping.
I can either fade-in and not loop the music, or loop the music without
fade in. Manually setting [volume.set()] the volume to any other level
works fine, looping works. Can anyone please help me out with this? I
just can't believe this can't be done effortlessly in a framework so
cool as PulpCore.

I wrote more about this problem here:
http://stackoverflow.com/questions/2525758/pulpcore-music-playback-loop-sound-and-animate-volume

and here is a link to the game I am writing. far from finished but far
from start :-)

What version of PulpCore are you using?

[Peter Perhac]

I believe the latest, pulpcore-0.11.5
Thanks for your attention. I would be so happy if you could shed some
light on this issue. The game is evolving, I have just uploaded the
latest changes, towers and traps both work as intended :-) well,
almost. a lot of work to do on the user interface etc... but I am
enjoying working with pulp core. It's really neat.

It is a PulpCore bug. When the output volume is zero, the sound player stops looping the sound.

To work around it, animate from a value that is not zero, like this:

musicVolume.animate(0.0001, 1, FADE_IN_TIME);

Thank you, thank you very much. Now I think I should have tried that.
But it wasn't really that obvious after all.
Is this going to be fixed in the next pulpcore release? I had a look
at the list of improvements for 0.11.6 and it's looking good.

Cheers and regards,

Peter
