How to use buttons and sounds with flash CS3

[Flep]

The attachSound method has also been removed.
Substantially it worked like the attachMovie method. Assigning a linkage ID to the audio file in library, it would be attached to the stage in runtime and reproduced using the attachSound.
As from now on, to attach a sound and reproduce it we will need to assign a class as an ID to the audio file in library.
With this article, we will see how to assign sounds to a button.
I would like to precise that the classic method of adding a sound directly to each state of the button is still valid. As FlepStudio is all about Flash programming, I feel the need to realize an example only using Actionscript 3.0.
Let's see the example...

I create a FLA and save it as 'sounds.fla', into which I create an instance on stage of a button named 'bottone_btn'.
I import 3 audio files in the library, one for the 'over' event, one for the 'out' event and one for the 'click' event.
I create a Document Class, an AS file saved as 'Main.as', implemented the following way:

package
{
	import flash.display.MovieClip;
	import flash.display.SimpleButton;
	import flash.events.Event;
	import flash.events.MouseEvent;
	
	public class Main extends MovieClip
	{
		public function Main()
		{
			initListener();
		}
		
		private function initListener():void
		{
			bottone_btn.addEventListener(MouseEvent.MOUSE_OVER,isOver);
			bottone_btn.addEventListener(MouseEvent.MOUSE_OUT,isOut);
			bottone_btn.addEventListener(MouseEvent.CLICK,isClick);
		}
		
		private function isOver(m:MouseEvent):void
		{
			var sound_over:Over=new Over();
		}
		
		private function isOut(m:MouseEvent):void
		{
			var sound_out:Out=new Out();
		}
		
		private function isClick(m:MouseEvent):void
		{
			var sound_click:Click=new Click();
		}
	}
}

Now, I create 3 classes which names will be used as the linkage ID for each audio file.
Three AS files:

Over.as

package
{
	import flash.media.Sound;
	import flash.media.SoundChannel;
	
	public class Over extends Sound
	{
		private var sound:SoundChannel;
		
		public function Over()
		{
			sound=play();
		}
	}
}

Out.as

package
{
	import flash.media.Sound;
	import flash.media.SoundChannel;
	
	public class Out extends Sound
	{
		private var sound:SoundChannel;
		
		public function Out()
		{
			sound=play();
		}
	}
}

Click.as

package
{
	import flash.media.Sound;
	import flash.media.SoundChannel;
	
	public class Click extends Sound
	{
		private var sound:SoundChannel;
		
		public function Click()
		{
			sound=play();
		}
	}
}

Back to the 'sound.fla', I assign to the choosen audio file for the 'mouse over' event, the ID 'Over'.
I assign to the choosen audio file for the 'mouse out' event, the ID 'Out'.
I assign to the choosen audio file for the 'click' event, the ID 'Click'.

Here is the result:

Let's analise the code:

Main.as Class
Methods
initListener();
I add a listener to the mouse event ( MOUSE_OVER, MOUSE_OUT and CLICK ) which will call the respective methods when the event takes place.
bottone_btn.addEventListener(MouseEvent.MOUSE_OVER ,isOver);
bottone_btn.addEventListener(MouseEvent.MOUSE_OUT, isOut);
bottone_btn.addEventListener(MouseEvent.CLICK,isCl ick);

isOver();
I create an instance of the Over class (which extends the Sound class and which is assigned to an audio file in library)
var sound_over:Over=new Over();

isOut();
I create an instance of the Out class (which extends the Sound class and which is assigned to an audio file in library)
var sound_out:Out=new Out();

isClick();
I create an instance of the Click class (which extends the Sound class and which is assigned to an audio file in library)
var sound_click:Click=new Click();

Over.as, Out.as and Click.as
Properties
an instance of the SoundChannel class
private var sound:SoundChannel;

Inside the respective building function ( public function Over() / Out() / Click() ) I tell SoundChannel to reproduce the sound
sound=play();
NB: this play() command refers to the class in which it is find, so, as the class extends the Sound class, it would be like saying SoundInstance.play();
NB: if you do not create the AS files, Flash will do it for you.

Stay tuned !

OK, it's nice to see someone can make sense of AS3 and it's backward-downgrade-ness.

How does all the code come together? I followed you steps but you never explained how it comes together to actually work. Can you post your sourse code, thanks.


I swear AS3 was screwed up on purpose just to sell books...
