Controlling system volume

Question

Hello,
I'm sure there is a simple script that once a user launches
the projector it will set their system volume to 50%, then when
they exit the projector there volume will return.
Please help
Thanks,
Devin

Answer 1

Put this in a movie script
-------volume control--------
global gOldVolume
on getSystemVolume
gOldVolume=baGetVolume("wave")
end
on setSystemVolume vNewVolume
baSetVolume("wave",vNewVolume)
end
on resetSystemVolume
baSetVolume("wave",gOldVolume)
end
------end volume control-------
Any time before you try setting the volume, run this once:
getSystemVolume()
Then, when you want to change the volume, do this:
setSystemVolume(someNumber)
where someNumber is an integer from 0 through 100. 0 means
mute. 100
means as loud as it can be. You can call that as many times
as you want
to change the volume as you please.
Then to reset it back to the way it was before you got to it,
use this
command:
resetSystemVolume()
A good place to put that is on stopMovie (or on your exit
button, or
whatever is the last thing that is done before the movie is
closed.
