AS3-如何从外部SWF加载MovieClip资产

Question

I exported a SWF file from an FLA with weather icons (as MovieClips) in the library. The linkage names are "IconX" (where X is the icon number from 0 to 25).

I want to use these icons on other templates... how can I load a specific MofieClip asset into a new template?

The SWF with the icons is called TP1023.swf and sits in the same place where the other templates will be.

The simplest way is to set a method in the loaded SWF that will return what you are asking for. ie:

public function getAsset(classId:String):DisplayObject {
    var c:Class = Class(getDefinitionByName(classId));
    if (!c) {
        trace("ERROR: class " + classId + " not found.");
        return null;
    }
    var d:DisplayObject = new c() as DisplayObject;
    if (!d) {
        trace("ERROR instantiating " + classId);
        return null;
    }
    return d;
}

I assumed it has to be general purpose, so it returns a DisplayObject. You can use other types too. Once you loaded the SWF and it is correctly initialized, you can retrieve any element you want:

var c:MovieClip = loadedSwf.getAsset("MyAssetId") as MovieClip;
