AS3調度自定義事件從類

Question

類

我想從國家（）STO的菜單按鈕（）派遣一個自定義事件;

CountryEvent

package { 
import flash.events.Event; 

public class CountryEvent extends Event { 

    public static const COUNTRY_HOVERED:String = "onCountryOver"; 

    private var _countryName:String = ""; 

    public function CountryEvent(type:String, countryName:String, bubbles:Boolean=true, cancelable:Boolean=false) { 
     super(type, bubbles, cancelable); 
     _countryName = countryName; 
    } 

    public function get countryName():String { 
     return _countryName; 
    } 

    public override function clone():Event 
    { 
     return new CountryEvent(type,countryName,bubbles,cancelable); 
    } 
} 

} 國家類

package 
{ 

    import flash.display.MovieClip; 
    import flash.events.MouseEvent; 
    import flash.events.Event; 

    public class Country extends MovieClip 
    { 
     private var countryEvent:CountryEvent; 


     public function Country() 
     { 
      this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver); 
      this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut); 
     } 

     private function onMouseOver(e:MouseEvent):void 
     { 

       countryEvent = new CountryEvent("onCountryOver",this.name); 

       dispatchEvent(countryEvent); 

      } 
     } 

     private function onMouseOut(e:MouseEvent):void 
     { 

     } 
    } 

} 

菜單按鈕類

當一個國家徘徊在自定義事件進行調度，這是我想要的菜單按鈕來聽，如果傳遞的參數是一樣得到突出了它的名字。鄉村類的基類爲我的國家的影片剪輯我在舞臺上的菜單按鈕的菜單按鈕的基類

看來，事件從來沒有經歷過

感謝得到提前

Answer 1

你有進行兩項修改：

首先，將您的活動bubbles屬性設置爲true，因此當Country剪輯發送一個事件時，它將進入頂層。

那麼你MenuButtons應該聽stage，而不是自己。所以，當一個Country調度一個事件就上升到stage，並且可以通過按鈕來捕獲。如果你要聽的階段，你必須做你的代碼略有變化：

public function MenuButton() { 

    this.buttonMode = true; 
    this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver); 
    this.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut); 
    this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage); 
} 

private function onAddedToStage(e:Event):void 
{ 
    removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage); 
    stage.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver); 
}

解決這一問題是由簡單的傳遞階段引用作爲一流水平的參數，並添加事件最好的和簡單的方法階段參考和派發事件到階段參考。

國家類

package{ 

import flash.display.MovieClip; 
import flash.events.MouseEvent; 
import flash.events.Event; 

public class Country extends MovieClip 
{ 
    private var countryEvent:CountryEvent; 
    private var _stageRef:Stage; 


    public function Country(pStageRef:Stage) 
    { 
     _stageRef = pStageRef; 

     this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver); 
     this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut); 
    } 

    private function onMouseOver(e:MouseEvent):void 
    { 

      countryEvent = new CountryEvent("onCountryOver",this.name); 

      _stageRef.dispatchEvent(countryEvent); 

     } 
    } 

    private function onMouseOut(e:MouseEvent):void 
    { 

    } 
} 

菜單按鈕類

package { 

import flash.display.MovieClip; 
import flash.events.MouseEvent; 
import CountryEvent; 


public class MenuButton extends MovieClip { 

    public var countryName:String = ""; 
    private var _stageRef:Stage; 

    public function MenuButton(pStageRef:Stage) { 
     _stageRef = pStageRef; 
     this.buttonMode = true; 
     this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver); 
     this.addEventListener(MouseEvent.MOUSE_OUT,onMouseOut); 
     _stageRef.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver); 
    } 

    private function onCountryOver(e:CountryEvent):void { 
     if(e.countryName == countryName) { 
      this.gotoAndPlay(2); 
     } 
    } 

    private function onMouseOver(e:MouseEvent):void { 
     this.gotoAndPlay(2); 

    } 

    private function onMouseOut(e:MouseEvent):void { 
     this.gotoAndPlay(11); 
    } 
}
