My example:
<!-- a button to mute/unmute the sound -->
<plugin name="snd" url="soundonoff.png" align="leftbottom" x="10" y="10" alpha="0.25" scale="1.0"
onover="tween(alpha,1);"
onout="tween(alpha,0.25);"
crop="0|0|50|50"
onclick="switch(soundinterface.mute); switch(crop, 0|0|50|50, 0|50|50|50);" />
<!-- play sound at 0/0 -->
<hotspot name="b1" url="button1.png" ath="0" atv="0" onclick="playsound3D(s1,music/music1.mp3, 0,0);" />
How to stop the concrete started melody (for exp music1.mp3)? And later to have the opportunity to start it again.
Thanks
