制作加载的图像拖动操作订阅3

Question

我想将图像加载到使用加载器的舞台上，然后我想使其拖动。如下所示，通过从Tilelist中进行选择来完成加载，但是我不知道在AS3中拖放，有人可以帮助我吗？我想让它尽可能简单。

这是我的代码加载图像：

var charge1:Loader = new Loader();
addChild(charge1);
this.addChildAt(charge1, getChildIndex(bg));
charge1.x = 280;
charge1.y = 270;

...

function setCharge1(e:Event):void{
    trace(e.target.selectedItem.source);

    this.charge1.load(new URLRequest(e.target.selectedItem.source));    
    this.charge1.contentLoaderInfo.addEventListener(Event.COMPLETE,onComplete);
}

Answer 1

Yuku沿着正确的线路行驶，但是您想做的是获得LoaderInfo的内容，实际上是加载的剪辑。

private function onComplete(event : Event) : void
{
  var loadedClip : MovieClip = LoaderInfo(event.target).content;

  loadedClip.addEventListener(MouseEvent.MOUSE_DOWN, function(event : MouseEvent) 
  {
    loadedClip.startDrag();
  });

  stage.addEventListener(MouseEvent.MOUSE_UP, function(event : MouseEvent) 
  {
      loadedClip.stopDrag();
  });

}

Answer 2

这是对我来说最简单的方法...

/* Load Image */

var myLoader:Loader = new Loader(); 
imageContainer.addChild(myLoader); 
var url:URLRequest = new URLRequest("photo.jpg"); 
myLoader.load(url);

/* Drag and Drop */

imageContainer.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
function pickUp(event:MouseEvent):void
{
imageContainer.startDrag();
}
stage.addEventListener(MouseEvent.MOUSE_UP, dopIt);

function dopIt(event:MouseEvent):void
{
imageContainer.stopDrag();
}

Answer 3

使用以下代码：

this.addEventListener(MouseEvent.MOUSE_DOWN, dragMovie);
this.addEventListener(MouseEvent.MOUSE_UP, dropMovie);
this.buttonMode = true;
private function dragMovie(event:MouseEvent):void
{
  this.startDrag();
}

private function dropMovie(event:MouseEvent):void
{
  this.stopDrag();
}

Answer 4

Loader是Sprite的子类，因此您可以使用StartDrag和Stopdrag方法。

例如：

charge1.addEventListener("mouseDown", function() {
    charge1.startDrag();
});

stage.addEventListener("mouseUp", function() {
    charge1.stopDrag();
});
