使用自定义LoaderInfo类自定义的AS3 Loader类？ [英] custom AS3 Loader class that uses a custom LoaderInfo class?

问题描述

这是一个问题，特别是有关创建自定义类加载器作为后续到<一个href="http://stackoverflow.com/questions/758322/how-do-i-modify-existing-as3-events-so-that-i-can-pass-data">http://stackoverflow.com/questions/758322/how-do-i-modify-existing-as3-events-so-that-i-can-pass-data.如果这不是正确的方式去了解这一点，让我知道。

This is a question specifically about creating a custom Loader class as a followup to http://stackoverflow.com/questions/758322/how-do-i-modify-existing-as3-events-so-that-i-can-pass-data. If this wasn't the right way to go about this, let me know.

我有一个自定义类加载器和一个自定义LoaderInfo类。我想不通的是如何让Loader类使用自定义LoaderInfo类，因为它的contentLoaderInfo属性。

I have a custom Loader class and a custom LoaderInfo class. What I can't figure out is how to have the Loader class use the custom LoaderInfo class as it's contentLoaderInfo property.

package com.display {
    import flash.display.Loader;

    import com.display.CustomLoaderInfo;

    public class CustomLoader extends Loader {
    	public var customData:*;

    	public function CustomLoader(passedData: *= null) {
    		customData = passedData;
    	}
    }
}

^要做的东西在里面，使之具有新的CustomLoaderInfo

^ Have to do something in there to make it have the new CustomLoaderInfo

package com.display {
    import flash.display.LoaderInfo;	
    import flash.events.Event;

    import com.events.CustomEvent;

    public class CustomLoaderInfo extends LoaderInfo {
    	public var customData:*;

    	public function CustomLoaderInfo(passedData: *= null) {
    		customData = passedData;
    	}		

    	override public function dispatchEvent(event:Event):Boolean {
    		var customEvent:CustomEvent = new CustomEvent(event.type, customData, event.bubbles, event.cancelable);
    		return super.dispatchEvent(customEvent);
    	}
    }
}

^可能的工作，但因为我不能让CustomLoader使用它，我还不知道。

^ That might work, but since I can't get CustomLoader to use it, I don't know yet.

推荐答案

我不知道它是如何融入你在做什么，但你不能懒得做一个扩展的LoaderInfo的。 Loader.contentLoaderInfo有一个属性称为装载器将返回装载程序（或在这种情况CustomLoader）用于那个。理论上你可以做到这一点与你有CustomLoader类：

I don't know how it fits into what you're doing, but you could not bother making an extended LoaderInfo at all. Loader.contentLoaderInfo has a property called loader that will return the Loader (or in this case CustomLoader) that was used. In theory you can just do this with the CustomLoader class that you have:

var loader: CustomLoader = new CustomLoader("Extra Data");
loader.load(new URLRequest("file.swf"));
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderComplete);

function loaderComplete(event: Event) : void
{
    var customData:* = (event.target.loader as CustomLoader).customData;
    trace(customData); // Extra Data
}
