Virtual CD Player with ActionScript! - Page 4

Volume Control, and attaching the sounds:

For the volume control SWFs I've used the same naming/numbering convention just to keep everything straight in my own head. To spare the length of this tutorial I will only illustrate one of them. It should also be noted that this is basically a modified version of the volume sliders you will learn from the book "Macromedia Flash 5, Training from the Source". It goes a little further into how exactly your sounds get attached with this and why. I got way exited when I learned about the soundObject from that, as you probably will too.

First open a new Flash document, save it as volume1.fla and create a button named "slider-button". This is just the fader itself. Next drop it on the stage and turn it into a movie clip named "volumeSlider". Inside this clip name the layer with your button something like "slider button", and add an actions layer. In the first frame of the actions layer you will define the slider position variables and attach your sound with this code:

top = this._y;
left = this._x + 100;
right = this._x;
bottom = this._y;
mySound = new Sound(this)
mySound.attachSound(this._name + "Sound");
mySound.start(0,999);

The last piece of code tells Flash how long to pause before playing your song, and then how many times to loop, which you want to be sure to set for yourself if you're copying-and-pasting this code.

Now select the button inside your volumeSlider movie clip and apply this action script to set the drag funcionality:

on (press) {
 this.startDrag(false, left, top, right, bottom);
 }
on (release, releaseOutside) {
 this.stopDrag();
 mySound.setVolume(100-(_x-right));
 }
