Sound.stop() and Sound.position()

[ousia]

@Herschel,

the button for play/pause in https://randomfoo.net/oscon/2002/lessig/free_culture.swf can stop and start the sound again from the start, but not from the the position where it has been paused.

This is common code for the slide transition:

var i = 1;
var time = 0;
var timing = new Array();
timing[1] = 16.826;
timing[2] = 11.846;
timing[3] = 4.822;
timing[4] = 5.687;
timing[5] = 5.451;
timing[6] = 4.114;
// and so on...

var ptiming = 0;
var ntiming = timing[i];
if(time == "0") {
   time = getTimer() + timing[i] * 1000;
   Slides.gotoAndStop(i);
   lessig = new Sound();
   lessig.attachSound("Lessig_32.mp3");
   lessig.start();
}

The AS2 code for that button reads:

on(release) {
   if(!paused) {
      pause_start = getTimer();
      pause_offset = lessig.position;
      lessig.stop();
      stop();
      paused = 1;
   } else {
      pause_time = getTimer() - pause_start;
      lessig.start(pause_offset / 1000);
      time = time + pause_time;
      play();
      paused = 0;
   }
}

But the weird thing is that both the button to advance the slide:

on(release) {
   if(i < timing.length) {
      if(1 < i) {
         ptiming = ptiming + timing[i - 1];
      }
      i++;
      Slides.gotoAndStop(i);
      lessig.stop();
      lessig.start(ntiming);
      time = getTimer() + timing[i] * 1000;
      if(i < timing.length){
         ntiming = ntiming + timing[i];
      }
   }
}

and the button to go to the previous slide work perfectly fine:

on(release) {
   if(1 < i) {
      ntiming = ntiming - timing[i];
      i--;
      Slides.gotoAndStop(i);
      lessig.stop();
      lessig.start(ptiming);
      time = getTimer() + timing[i] * 1000;
      if(1 < i) {
         ptiming = ptiming - timing[i - 1];
      }
   }
}

I wonder whether it might be related to an issue with Sound.position() (I guess it has been implemented, but I really don’t know 😅).

[Herschel]

Sound.position not implemented quite yet (cc #273).

[ousia]

@relrelb, it would be really great if you could implement Sound.position(), once #1445 is merged.

This would help to test other AS2 functionality on animations that depend on it.

Many thanks for your excellent work.

@relrelb I don’t know whether this could make sense (so, take it with a grain of salt).

Since #1445 may take time to be merged, I wonder if the Sound.position() could start before #1445 has been merged.

Just in case it might help. Many thanks for your excellent work.

Fixed by #2825?

[Herschel]

Sound.stop is completely implemented in #2825, but haven't yet done Sound.position. I'll do this next.

This is really excellent news.

Many thanks for your excellent work

Looking forward Sound.position() being implemented.

[Herschel]

Thanks for the patience @ousia :-)

Many thanks for the fix, @Herschel.

Now I have another issues that I can follow better 😅.
