| |  | |
I am using the following code to toggle the sound volume from 0 to 100 using a
button. It works fine and collects the value for the variable called
soundVolume as I want it to. What I need is a way to set the timeline volume
using the variable soundVolume's value when entering the frame. I will be
collecting the value for soundVolume from another application on start. I have
tried several ways and nothing seems to work. Any suggestions?
//This variable holds the state of sound volume and passes and collects
to/from so
// the flash files keep the sound level the same from page to page (i.e. the
user does
//not have to keep clicking mute to change the volume state
var soundVolume:Number;
//following code sets the new button for when sound is off as visible
var mute_mc2 = _root.attachMovie("mute_mc2", "mute_mc201", 99);
mute_mc201._visible = false;
mute_mc201._x = -193;
mute_mc201._y = 212.0;
//following code sets the visibility state of the mute button depending on the
variable SoundVolume
onEnterFrame = function () {
if (soundVolume == 0) {
mute_mc201._visible = true;
mute_mc201._x = 187.9;
mute_mc201._y = 248.0;
mute_mc._visible = false;
} else if (soundVolume == 100) {
mute_mc201._visible = false;
mute_mc._visible = true;
}
};
//The following code mutes the sound and sets the sound volume variable
var allsound:Sound = new Sound(this);
mute_mc.onRelease = function() {
if (allsound.getVolume() == 100) {
allsound.setVolume(0);
soundVolume = 0;
} else if (allsound.getVolume() == 0) {
allsound.setVolume(100);
soundVolume = 100;
}
trace(soundVolume);
};
mute_mc2.onRelease = function() {
if (allsound.getVolume() == 100) {
allsound.setVolume(0);
soundVolume = 0;
} else if (allsound.getVolume() == 0) {
allsound.setVolume(100);
soundVolume = 100;
}
trace(soundVolume);
}; |

what do you mean by, "the timeline volume"?
if you mean the volume for a sound attached to your timeline, none of the
sounds properties can be controlled by actionscript (except stopping that sound
along with all others using stopAllSounds() ). |

Hmmm.....the code I am showing actually does set the volume of the audio that
is in the timeline. The audio is not called using "attachSound" and the audio
file in the library is not set to export to actionscript. When you click the
button, if the sound volume is currently at 100, it changes to 0. If the sound
volume is currently at 0, it changes to 100. It isn't stopping the sound,
because everything is staying synched.
I want to be able to set the volume when the swf file first starts playing
based on the value of the variable soundVolume. In other words, to act similar
to the button but based on the value of soundVolume. |

| FYI, this code is on frame 1. Sorry if the additional code for setting the visibility of the buttons is distracting. |

you're correct.
use:
allsound.setVolume(soundVolume); |

The code that you show is creating a sound object named allsound. The two
buttons mute_mc and mute_mc2 are toggling the value of the volume property for
that sound object between 0 and 100. Ordinarily, as kglad stated, you can't
control a sound that is directly attached to a keyframe in the timeline. This
is wild sound and will play at whatever volume is set at the keyframe where it
begins. The sound object allsound that is instantiated in the code will control
any sound in the movie that is not attached to another sound object. While this
works, it is not good practice.
You could use setVolume() to set an initial value for the sound at the frame
where the sound begins to play. Since the sound object is instantiated in the
first frame, you can use allsound.setVolume() to any value that you want
between 0 and 100 at that keyframe.
The variable soundVolume is only used inside the two onRelease functions and
has no meaning whatsoever. You don't need it inside the function or outside.
That onEnterFrame function is just tying up processor cycles. You can replace
all of that code by transferring the visible toggle to the onRelease functions.
There is no need to reset the visible of any movieClip 30 times a second. |

Thanks, Rob. I see what you are saying about moving the onEnterFrame code over
to the onRelease code. It would be more efficient. I will try that.
I am still working on getting flash to recognize the soundVolume variable when
it is passed to the swf file from the other application. I will post if I get
it to work.
Thanks,

Just to let you know, I got it working!! I am so happy!
I ended up moving my buttons out of flash and those functions are occuring in
the other application. The buttons send set variable commands to flash to
adjust the volume. Thanks to kglad and Rob for your suggestions.
Here is the new code for frame one:
//variable to pass back and forth from external application to control sound
on and sound off. Initial volume set to on.
var soundVolume:Number;
soundVolume = 100;
//sets the sound volume on any frame based on the value of soundVolume variable
this.onEnterFrame = function () {
var allsound:Sound = new Sound(this);
allsound.setVolume(soundVolume);

A couple of things that you might want to consider: If you place that
onEnterFrame function in the timeline of your movie, its going to run forever.
So, if you place that function at frame 10, and then the playback head moves
on, the function is still running over and over and over again. You really only
want to set or change the volume once. You can do that from any keyframe, just
like calling the function, like this:
var allsound:Sound = new Sound(this);
allsound.setVolume(soundVolume);
at the keyframe where you want to change the volume.
Alternately, you could place the volume setting function at the first frame
where you are creating the variable:
var soundVolume:Number = 100;
function changeVolume(newVolume) {
var allsound:Sound = new Sound(this);
allsound.setVolume(newVolume);
}
Then you can call the function from anywhere in the movie, even the first
frame like this:
changeVolume(soundVolume);
This will take the value of the soundVolume variable and pass it to the
function that will set the new volume to that value. |
