Type not found error for sound

Question

Hi,

I am a newbie for ActionScript. I would like to add Sound dynamically to my flv. I have this code. I am pretty sure it is working because I found it in Textbook. :(.

package{
 import flash.display.Sprite;
 import flash.media.Sound;
 import flash.net.URLRequest;

 public class soundLoader extends Sprite{
  private var sound:Sound;

  public function soundLoader(){
   sound = new Sound(new URLRequest("sound.mp3"));
   addChild(sound);
  }

 }

}

When I try to run the code I got these error messages.

1046: Type was not found or was not a compile-time constant: Sound.

1180: Call to a possibly undefined method Sound.

Where did I do wrong? Please,please help me.

Answer 1

There are a few things that are wrong with this code. First of all, by convention class names in AS3 start with an upper case letter, so you should rename your class SoundLoader and not soundLoader. Second, the Sound object in AS3 is not a display object so you can't add it to a sprite's display list. Therefor the call to addChild( sound ) is wrong, and will cause compile errors.

That doesnt solve your probleme however. Are you using Flash or Flex to write this code ?

Answer 2

here is my flash file: http://www.signalsondisplay.com/sotest.rar I wrote it in Flash CS4 so I don't know if you can open it with CS3. Hope it helps, because I have no idea why you get that error. Try checking your classpath and that sort of stuff in the swf settings.
