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);
