Flash AS3 文档类中未定义的属性 MouseEvent

这是我第一次尝试在 AS3 中使用文档类，但我很挣扎。我正在尝试将事件侦听器添加到 2 层深度的影片剪辑中，等待单击，但出现以下错误。

ERROR: Access of undefined property MouseEvent

package 
{
 import flash.display.MovieClip;
 import flash.media.Sound;
         import flash.media.SoundChannel;

 public class game extends MovieClip
 {
  public var snd_state = true;

  public function game()
  {
   ui_setup();
  }

  public function ui_setup()
  {
   ui_mc.toggleMute_mc.addEventListener(MouseEvent.CLICK, snd_toggle);
  }

  public function snd_toggle(MouseEvent)
  {
   // 0 = No Sound, 1 = Full Sound
   trace("Toggle");
  }
 }
}

this is my first time trying to use document classes in AS3 and im struggling.
I am trying to add event listeners to a 2 levels deep movie clip, waiting for a click however i am getting the following error.

ERROR: Access of undefined property MouseEvent

package 
{
 import flash.display.MovieClip;
 import flash.media.Sound;
         import flash.media.SoundChannel;

 public class game extends MovieClip
 {
  public var snd_state = true;

  public function game()
  {
   ui_setup();
  }

  public function ui_setup()
  {
   ui_mc.toggleMute_mc.addEventListener(MouseEvent.CLICK, snd_toggle);
  }

  public function snd_toggle(MouseEvent)
  {
   // 0 = No Sound, 1 = Full Sound
   trace("Toggle");
  }
 }
}

如果您要使用一个类，则需要导入它。编译器告诉您，您已经引用了 MouseEvent 类，但没有将其包含在代码中。我已经为您清理了一些：

package 
{
 import flash.display.MovieClip;
 import flash.events.MouseEvent; // <-- import MouseEvent Class
 import flash.media.Sound;
 import flash.media.SoundChannel;

 public class game extends MovieClip
 {
  public var snd_state:Boolean = true; // -- snd_state is type Boolean

  public function game()
  {
   ui_setup();
  }

  public function ui_setup():void
  {
   ui_mc.toggleMute_mc.addEventListener(MouseEvent.CLICK, snd_toggle);
  }

  private function snd_toggle(event:MouseEvent):void
  {
   // 0 = No Sound, 1 = Full Sound
   trace("Toggle");
  }
 }
}

您会注意到我在方法末尾添加了 :void 。这表明要返回什么类型的变量。例如，如果您的方法返回一个字符串，则它将是 :String。还向您的 snd_toggle 处理程序添加了一个参数。该参数称为“event”，它是类 MouseEvent (event:MouseEvent) 的实例。

If you're going to use a class, you need to import it. The compiler is telling you that you've referenced the MouseEvent class but didn't include it in your code. I've cleaned it up a bit for you:

package 
{
 import flash.display.MovieClip;
 import flash.events.MouseEvent; // <-- import MouseEvent Class
 import flash.media.Sound;
 import flash.media.SoundChannel;

 public class game extends MovieClip
 {
  public var snd_state:Boolean = true; // -- snd_state is type Boolean

  public function game()
  {
   ui_setup();
  }

  public function ui_setup():void
  {
   ui_mc.toggleMute_mc.addEventListener(MouseEvent.CLICK, snd_toggle);
  }

  private function snd_toggle(event:MouseEvent):void
  {
   // 0 = No Sound, 1 = Full Sound
   trace("Toggle");
  }
 }
}

You'll note that I added :void to the end of your methods. This indicates what type of variable to return. For example, if your method returns a string it would be :String. Also added a paramter to your snd_toggle handler. The parameter is called "event" and it's an instance of class MouseEvent (event:MouseEvent).
