添加MouseEvent.CLICK到八哥形象 [英] add MouseEvent.CLICK to starling image

问题描述

我有一个容器有滚动许多图像，我添加 TouchEvent.TOUCH 作为事件监听器，而不是 MouseEvent.CLICK ，因为八哥不支持的MouseEvent 。 问题是，当我浏览的图像将监听器，的TouchEvent 之间，而我并不需要这个？有没有解决办法，而不是 TouchEvenet ？

在code：

 私有函数的onComplete（事件：对象类型：flash.events.Event）：无效
    {
        位图数据=位图（的LoaderInfo（将event.target）.content）.bitmapData;
        VAR newImage：图片= Image.fromBitmap（位图（的LoaderInfo（将event.target）.content））;
        newImage.height = 154;
        newImage.width = 180;
        的addChild（newImage）;
        newImage.addEventListener（starling.events.TouchEvent.TOUCH，image_clickHandler）;
    }
    私有函数image_clickHandler（事件：starling.events.TouchEvent）：无效
    {
        VAR触摸：触摸= event.getTouch（阶段）;
        如果（碰！= NULL）
        {
            如果（touch.phase == TouchPhase.BEGAN）
            {
                //一些code
            }
        }

    }
 

解决方案

这是一个很好的做法，是不会把事件侦听器的每次在场景中的对象。你应该只附着一个监听到舞台，之后读触摸事件的目标属性。
这里从Inroducing八哥的例子书

 私有函数的onClick（E：的TouchEvent）：无效
{
 VAR接触：矢量＆lt;触摸和GT。 = e.getTouches（本）;
 VAR点击：的DisplayObject = e.currentTarget为的DisplayObject;
 如果（touches.length == 1）
 {
  VAR触摸：触摸=触摸[0];
  如果（touch.phase == TouchPhase.ENDED）
  {
   跟踪（e.currentTarget，e.target）;
  }
 }
}
 

下面， currentTarget当前是舞台和目标将你的形象

i have a container have many image with scroll , i add TouchEvent.TOUCH as event listener instead of MouseEvent.CLICK , because starling doesn't support MouseEvent . the problem is when i navigate between images it will listener to TouchEvent while i don't need to this ? is there any solution instead of TouchEvenet ?

the code :

private function onComplete (event:flash.events.Event):void
    {
        bitmapData = Bitmap(LoaderInfo(event.target).content).bitmapData;
        var newImage:Image = Image.fromBitmap(Bitmap(LoaderInfo(event.target).content));
        newImage.height = 154;
        newImage.width = 180;
        addChild(newImage);
        newImage.addEventListener(starling.events.TouchEvent.TOUCH,image_clickHandler);
    }
    private function image_clickHandler(event:starling.events.TouchEvent):void
    {
        var touch:Touch = event.getTouch(stage);
        if (touch != null)
        {
            if (touch.phase == TouchPhase.BEGAN)
            {
                //some code
            }   
        }

    }

解决方案

It's a good practice not to attach event listeners to every objects on scene . You should attach only one listener to stage and after that read touch event's target property.
Here the example from "Inroducing Starling" book:

private function onClick(e:TouchEvent):void
{
 var touches:Vector.<Touch> = e.getTouches(this);
 var clicked:DisplayObject = e.currentTarget as DisplayObject;
 if ( touches.length == 1 )
 {
  var touch:Touch = touches[0];   
  if ( touch.phase == TouchPhase.ENDED )
  {
   trace ( e.currentTarget, e.target );
  }
 }
}

Here , currentTarget is Stage , and target will be your image
