Michel,
Thanks for your reply. I also found this reference after I made my post. I am still uncertain about what this should look like in my code because nothing I am trying seems to work.
Should it be:
<plugin name="soundinterface" url="plugins/soundinterface.swf" onloaded="playsound3D(s2,forest.mp3, 180,0, 120,0);" />
or do I need to reference the function like:
<plugin name="soundinterface" url="plugins/soundinterface.swf" onloaded="playsound3D(s2,forest.mp3, 180,0, 120,loops0);" />
Sorry...just trying to learn XML syntax
