将 MouseEvent.CLICK 添加到八哥图像 [英] add MouseEvent.CLICK to starling image

问题描述

我有一个容器有很多带有滚动的图像，我添加 TouchEvent.TOUCH 作为事件侦听器而不是 MouseEvent.CLICK ，因为 Starling 不支持 鼠标事件 .问题是当我在图像之间导航时，它会监听 TouchEvent 而我不需要这个?有什么解决方案可以代替 TouchEvenet 吗?

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 ?

代码:

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
            }   
        }

    }

推荐答案

最好不要将事件侦听器附加到场景中的每个 对象.您应该只将 一个 侦听器附加到舞台上，然后读取触摸事件的 target 属性.
这是介绍 Starling"一书中的示例:

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 );
  }
 }
}

这里，currentTarget 是 Stage ，target 将是你的形象

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