I've been going through a few tutorials, trying to find how to embed audio files and play them in AS3, and they tend to show examples which are very similar. However when I try to use these examples, nothing is played. My mp3 file will be embedded successfully, all the lines of code will execute sucessfully, but there will just be no sound. Take the following code, for instance:
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.media.Sound;
public class Main extends Sprite
{
[Embed(source='/../lib/Kalimba.mp3')]
private var MySound : Class;
private var sound : Sound;
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init(e:Event = null):void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
sound = (new MySound()) as Sound;
sound.play();
}
}
}
What's going wrong here? Many examples online basically use this code, just changing variable names and the like. I'm using FlashDevelop, in case that makes any difference. Thanks.
EDIT
Apparently it's somehow linked to that file. I tried Kalimba.mp3, Maid with the Flaxen Hair.mp3, and Sleep Away.mp3, all of which are Windows 7 defaults in Libraries\Music\Sample Music. None of them worked. Then I downloaded a random mp3 file elsewhere and tried to use it, and it worked just fine (Blackbird Blackbird - Heartbeat.mp3 from http://www.last.fm/music/+free-music-downloads/sample). I have tried using converters to make sure Kalimba was at 44100 Hz with a bitrate of 128 kbps, but that didn't seem to work. What's the difference?
It worked perfectly for me with your code. Check your mp3 file. Try a different file and see if it works.
Also check for silly mistakes like:
Have you used addChild() to add instance of Main class? The init() in your Main.as will fire only after you've added it to display list
Is the pathing in your source correct? I've changed my path to "test.mp3", put your mp3 in a root folder to be sure.

Help me, I use Adobe Flash CS3 Professional.
// i have try using this import, but still not work
/*import flash.events.Event;
import flash.media.Sound;
import flash.net.URLRequest;
*/
// here is the code
var req:URLRequest=new URLRequest("music.mp3");
var snd:Sound=new Sound();
snd.load(req);
var chan:SoundChannel=snd.play();// not work using 'snd.play(1);' too
chan.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);
function onPlaybackComplete(event:Event){
trace("Musik Complete");
}
When i run the swf or ctrl+enter, the output Musik Complete without any sound played, but the animation still played. For the animation i just create simple twin motion.
i work on this directory
C:/flash/example.fla
C:/flash/example.swf
C:/flash/music.mp3
I have try to import music.mp3 into the library too.
Note: I get the example from my friend(.swf, .fla, .mp3). I play the .swf that shared by my friend and work, but when i try to create by my self, is not work. So, i think music.mp3 was fine to use for Flash. Here is my friend code:
var Audio:musik = new musik();
var chan:SoundChannel = new SoundChannel();
// play
chan=Audio.play();
// stop
chan.stop();
// i am so confuse i run my friend project and work fine (sound and other), if i write from scrap even i write the same code, there is an error, and this the error:
// 1046: Type was not found or was not a compile-time constant: musik.
// 1180: Call to a possibly undefined method musik.
I just watch on youtube, i missing one step.
In library, open properties of music.mp3 and give it class name.
So, we can call the class using this var Audio:musik=new musik();.
Then, create the Sound Channel.
At least, function to play and stop using this:
//play
chan=Audio.play();
// stop
chan.stop();
How can I patch actionscript without constantly rebuilding sfw?
There is a fairly large actionscript project that I need to modify and resulting swf is used on a live site. The problem I have is that I need to make quick small updates to the swf and it's not acceptable to update the swf on live site ten time a day (I don't control that part, I need to ask another person to put the result on live site).
What options do I have to workaround that issue? I'm a complete noob when it comes to actionscript and all flash related stuff and I'm not even sure what is possible and what isn't. I'm thinking about the following approaches, which ones are possible/acceptable?
Imagine that live site is on www.livesite.com/game.html and this page loads www.livesite.com/flashgame.swf. In that flashgame.swf among many others there is a class com/livesite/Magic.as that gets instantiated and instance of that class has a member variable xxx123 of class com/livesite/MagicWork.as. I only need to modify this MagicWork class. Now, I simply modify it, build and ask to put updated flashgame.swf live. So, I want to avoid that manual step.
All my ideas can be split in two basic approaches: 1) keep flashgame.swf totally unmodified and then load flashgame.mod.swf that contains alternative implementation of that MagicWork class, then using javascript access internals of instance of that Magic class and update its xxx123 member to be an instance of MagicWork class from flashgame.mode.swf. I'd need to modify game.html to load my javascript so that my js file would load flashgame.mod.swf and patch code inside flashgame.swf. By patching I mean javascript-style overwriting of Magic.xxx123 to a new value. flashgame.mode.swf would ideally reside on my own host that I control. Is that kind of stuff possible, if not what's not possible?
2) I could make one-time change in flashgame.swf so that it would effectively load itself my own code at runtime and patch it's xxx123 member. Is that possible?
I had already written a note about loading runtime shared libraries previously. I'll put the most essential parts of the process here, and add a link to the full article at the end.
You need to tag your main application entry point in the following manner.
[Frame(factoryClass="Preloader")]
public class Main extends Sprite
{
}
Then create a class called Preloader.
public class Preloader
{
public function Preloader()
{
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, this.loader_completeHandler);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, this.loader_ioErrorHandler);
var request:URLRequest = new URLRequest("math.swf");
var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);
loader.load(request, context);
}
private function loader_completeHandler(event:Event):void
{
var mainClass:Class = getDefinitionByName("Main") as Class;
var mainInstance:Main = new mainClass();
this.addChild(mainInstance);
}
}
The full implementation of the Main class is like this.
[Frame(factoryClass="Preloader")]
public function Main()
{
var integer:IntegerArithmetic = new IntegerArithmetic(); // Type declared in math.swf
var operand1:int = 10;
var operand2:int = 10;
var result:int = integer.add(operand1, operand2);
}
Deploying Runtime Shared Libraries
The confusing bit about using a runtime shared library is realizing that the SWF has to be extracted from the SWC at the time of deploying the application. This was not immediately obvious and I ended up spending days placing a compiled SWC file in various locations and wondering why the application was unable to load it at runtime. An obscure article on the Adobe website made explicit this particular step and set things straight.
The full article along with the same example is available at http://www.notadesigner.com/runtime-shared-libraries-with-plain-actionscript/.
I've found several articles relating to variable FlexVersion and error 1065, but nothing seems to help.
EDIT:I've attempted to implement SEVERAL guides on embedding images into flashDevelop with the same result. Everything works correctly until I try to add the embedded image, then I get the above error.
Has no one here seen this error?
My Class (which I've stripped down to nothing in order to pinpoint the issue):
package {
import flash.display.Sprite;
import flash.display.Bitmap;
public class JMouse extends Sprite {
[Embed(source = "../lib/jacobsLadder.png")]
private var Picture:Class;
//private var pic:Bitmap = new Picture(); // THIS LINE
public function JMouse() {
init();
}
private function init():void {
}
}
throws the error when the line "THIS LINE" is not commented out. I've tried adding "as Bitmap" to the end of this line without luck.
I am calling this class from my document class:
jMouse = new JMouse();
the file, jacobsLadder.png, is in my lib folder, and I used FlashDevelop to "Generate Embed Code."
I am using FlashDevelop 5.0.1.3 for .NET 3.5
Any Ideas?
EDIT: I also tried this (and similar variations), as per the suggestion:
"The type of code you can run at variable declaration scope is limited. Creating an instance of Picture requires decoding and so will fail at that point. Instead create your instance of Picture within an instance methods or the constructor."
[Embed(source = "../lib/jacobsLadder.png")]
public static var Picture:Class;
public function JMouse() {
var pic:Bitmap = new Picture();
init();
}
But I get the same error.
The type of code you can run at variable declaration scope is limited. Creating an instance of Picture requires decoding and so will fail at that point. Instead create your instance of Picture within an instance methods or the constructor.
ANSWER: Load the bitmapdata with a loader.
Although the OP (me) was asking how to embed the file, the mysterious problem of "Error #1065: Variable FlexVersion is not defined" issue is apparently an insurmountable one, and I hope that anyone else who may come across this problem may find solace in the following (courtesy of John Mark Isaac Madison et al):
How do you load a bitmap file into a BitmapData object?
While not the an answer, per se, it at least allows the OP to continue on in his work as an alternative to lighting his house on fire.
Been bangin my head against a wall all day, thought I'd see if anyone can shed some light on this -
I have an iOS air app that imports a remote swf. Once imported, an event listener is added to a button inside the imported swf. Clicking the button causes the app to hang. Here's some code -
private function loadRemoteSWF():void{
var urlRequest:URLRequest = new URLRequest("http://www.domain.com/remote.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaded);
loader.load(urlRequest);
}
private function onLoaded(e:Event):void{
var loaderInfo:LoaderInfo = e.currentTarget as LoaderInfo;
var adPanel:MovieClip = loaderInfo.content as MovieClip;
adPanel.continueButton.addEventListener(TouchEvent.TOUCH_BEGIN, onContinueClicked);
addChild(adPanel)
}
private function onContinueClicked(e:TouchEvent):void{
trace("onContinueClicked");
}
I'm using Flash Builder 4.7 AIR SDK 3.5 ASC 2.0.
This only happens on a release build, debug builds work fine so near impossible to find the cause. It also works fine when using the legacy compiler on the same SDK version.
Dispatching a touch event programatically on the button also works fine. (thought I could do a try/catch to find an error)
adPanel.continueButton.dispatchEvent(new TouchEvent(TouchEvent.TOUCH_BEGIN));
Touching the button just kills the app, it doesn't even hit the trace.
Anyone got any ideas how to debug this, or why this problem might be happening?
Thanks
Dave
can you do a test: instead of using the the native loader, try using an API, like greensocks api - SWFLoader.
Also, try setting the accepted domains through the security class prior to loading the swf file:
import flash.system.Security;
public class Main extends MovieClip{
public function Main(){
Security.allowDomain("*");
}
}
I would suggest trying to compile with the same setup on a different machine, just to make sure that the Builder install doesn't have some issues.
Also, have you tried on different devices, (could be an issue with the device you are using)?
The code below compiles fine on the Flex 4 SDK on Fedora 15. Mouse-click opens the dialog box, I click okay, and a file is saved, but the file is empty. I run the same SWF file (that was compiled on the Linux machine) on a Windows machine, and the created file contains the expected data.
Then I broke the FileReference declaration out of the function into the class level, hoping to avoid a known bug, but the same problem persists.
Hoping to set up a workaround, I added the debug Flash player to my path and ran the file from Flash without the benefit of the browser, and it works. So now a Flex problem has become a Firefox problem, maybe owing to a shady procedure I used to install the plugin without really understanding what was happening. I am running Firefox 5.0.
In essence my workflow is fixed, but perhaps people who performed the above will not be able to use projects with FileReference.save()? Should I be worried about this edge case?

EDIT: was missing a line, fixed above
EDIT: addressed answer in code above, but the same problem exists.
EDIT: This works on the same system when the standalone player is invoked. Therefore this is a browser (FF 5.0) plugin problem.
Try putting the line
var fr:FileReference = new FileReference();
at class level (outside the function). Apparently this is a known bug:
