AS3 | Load image from URL and start drag issue - actionscript-3

Question

I try to add image from URL address and start drag it when i click it, but i can't make drag function.
var url:String = 'http://www.helpexamples.com/flash/images/image1.jpg';
var urlRequest:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete);
loader.load(urlRequest);
addChild(loader);
function loader_complete(evt:Event):void {
var target_mc:Loader = evt.currentTarget.loader as Loader;
target_mc.x = (stage.stageWidth - target_mc.width) / 2;
target_mc.y = (stage.stageHeight - target_mc.height) / 2;
target_mc.addEventListener(MouseEvent.CLICK, startDraging);
}
function startDraging(e:MouseEvent):void {
var obj:MovieClip = e.target as MovieClip;
obj.startDrag();
}

Answer 1

The issue here is that in your complete function loader_complete() you set target_mc to a type Loader. Loaders do not have access startDrag() or stopDrag().
What you can do is create a new MovieClip and add your loaded content to that MovieClip. So in your loader_complete():
function loader_complete(evt:Event):void {
var target_mc:MovieClip = new MovieClip(); //new movieclip
target_mc.addChild( evt.target.content ); //add the content
target_mc.x = (stage.stageWidth - target_mc.width) / 2;
target_mc.y = (stage.stageHeight - target_mc.height) / 2;
target_mc.addEventListener(MouseEvent.CLICK, startDraging);
addChild( target_mc ); //add target_mc
}
Now your start drag should work.
