Re: [Swftools-common] Re: stereo sound(track)

[Chris Pugh]

Hi Russ,

A Transform object isn't a full Pan.  There's a separate command
for that,

( bear in mind what that page says about how it works )

The choice whether to embed or stream, is entirely yours.

Enbed:

  .sound myMp3 "my_sound.mp3"

then use, attachSound() with the id name to use
the sound.

Stream this way,

  var snd=new Sound();
  snd.loadSound("my_sound.mp3", True);

All the sound commands ( for basic AS2 ) are here,

I've confused the heck out of both of us, writing those examples
on the fly.  I should put some order into them then, then do as
originally suggested.. post them to the wiki.

Regards,


Chris.

PS  Sounds to play with,
