I'm starting with Loader.But I have a problem.I want to call MovieClip from external swf.My code works in flash cs3.I get some error in haXe.
My code:package { import flash.display.MovieClip; import flash.display.Loader; import flash.display.DisplayObject; import flash.net.URLRequest; import flash.events.Event; import flash.utils.getQualifiedClassName; public class Main extends MovieClip { var loader:Loader=new Loader(); public function Main() { loader.load(new URLRequest("ExSwf.swf")); loader.contentLoaderInfo.addEventListener(Event.COMPLETE,comp); } var clsObj:Object; function onframe(ev:Event){ clsObj.rotation++; } function comp(event:Event):void { //error.How to change 'as Class' to haXe? var cls:Class=event.target.content.loaderInfo.applicationDomain.getDefinition("box")as Class clsObj=new cls(); clsObj.x=100; clsObj.y=100; //error in DisplayObject addChild(DisplayObject(clsObj)); processCompleted(); stage.addEventListener(Event.ENTER_FRAME,onframe); function processCompleted():void { trace(getQualifiedClassName(cls)); } } } }
thanks -
Haxe is stricter than AS3 so it is hard to be sure without me running the code, it looks roughly fine. I have enclosed some old haxe flash code that maybe useful? I tend to use signals now but maybe it's useful. In haxe we tend to use Type and Reflect for some aspects of what your doing see http://haxe.org/doc/cross/reflect. The code below may have bugs in some of the preloader info, it's just the first non signal loading stuff I could dig up, used on a very small project, but largely it all works so it maybe useful.

I think the third class i posted assumes a certain timeline structure so you may need to adjust it to your needs but should atleast give ideas :)

Very detailed.It is quite hard.Thanks again.Now,I know two ways: the way of your and loader a resource.swf contains movieclip at server

I am not expert on code theories, but normally I find away to make stuff, what are you trying to create, maybe i can help. People often ask one thing, but... if they say what they want to do, or more rightly and what they actually want to create - it's easier than understanding their code arrangement, even if I can only offer a part of the solution.
Cheers
