getPan (Sound.getPan method) -- Flash CS3

Returns the pan level set in the last setPan() call as an integer from -100 (left) to +100 (right). (0 sets the left and right channels equally.) The pan setting controls the left-right balance of the current and future sounds in a SWF file.

Returns

Example

The following example creates a slider bar using the Drawing API. When the user drags the slider bar, the pan level of the loaded sound changes. The current pan level is displayed in a dynamically created text field. Add the following ActionScript to your FLA or AS file:

var bar_width:Number = 200;
this.createEmptyMovieClip("bar_mc", this.getNextHighestDepth());
with (bar_mc) {
    lineStyle(4, 0x000000);
    moveTo(0, 0);
    lineTo(bar_width+4, 0);
    lineStyle(0, 0x000000);
    moveTo((bar_width/2)+2, -8);
    lineTo((bar_width/2)+2, 8);
}
bar_mc._x = 100;
bar_mc._y = 100;

this.createEmptyMovieClip("knob_mc", this.getNextHighestDepth());
with (knob_mc) {
    lineStyle(0, 0x000000);
    beginFill(0xCCCCCC);
    moveTo(0, 0);
    lineTo(4, 0);
    lineTo(4, 10);
    lineTo(0, 10);
    lineTo(0, 0);
    endFill();
}
knob_mc._x = bar_mc._x+(bar_width/2);
knob_mc._y = bar_mc._y-(knob_mc._height/2);

knob_mc.left = knob_mc._x-(bar_width/2);
knob_mc.right = knob_mc._x+(bar_width/2);
knob_mc.top = knob_mc._y;
knob_mc.bottom = knob_mc._y;

knob_mc.onPress = function() {
    this.startDrag(false, this.left, this.top, this.right, this.bottom);
};
knob_mc.onRelease = panSound;
knob_mc.onReleaseOutside = panSound;

function panSound():Void { {
    this.stopDrag();
    var multiplier:Number = 100/(this.right-this.left)*2;
    var pan:Number = (this._x-this.left-(bar_width/2))*multiplier;
    my_sound.setPan(pan);
    pan_txt.text = my_sound.getPan();
};

var my_sound:Sound = new Sound();
my_sound.loadSound("song2.mp3", true);
this.createTextField("pan_txt", this.getNextHighestDepth(), knob_mc._x, knob_mc._y+knob_mc._height, 20, 22);
pan_txt.selectable = false;
pan_txt.autoSize = "center";
pan_txt.text = my_sound.getPan();

The MovieClip.getNextHighestDepth() method used in this example requires Flash Player 7 or later. If your SWF file includes a version 2 component, use the version 2 components' DepthManager class instead of the MovieClip.getNextHighestDepth() method.
