是否可以创建动态嵌入功能？

是否可以在 ActionScript3 中创建动态嵌入函数，

例如像这样

     public function embedImage(path:String):Bitmap{
            [Embed(source = path, mimeType = "image/png")]
        var NewBitmapClass:Class;

            var image:Bitmap=new NewBitmapClass();
            return image;

     }// tried it, it doesnt work

或以其他方式，或者即使它完全可能？

Is it possible to create dynamic embed function in ActionScript3

for example like this

     public function embedImage(path:String):Bitmap{
            [Embed(source = path, mimeType = "image/png")]
        var NewBitmapClass:Class;

            var image:Bitmap=new NewBitmapClass();
            return image;

     }// tried it, it doesnt work

or maybe in some other way, or even if it is at all possible?

您可以使用“动态”部分获得的最接近的是创建一个包装类，您可以在其中定义图像，并且稍后可以通过 id 将它们获取为位图。
不幸的是，这些属性是公共的，否则 hasOwnProperty 函数不会返回 true。（如果有人找到更好的方法，请告诉我）

见下文：

package {
import flash.display.Bitmap;

public class DynamicEmbed {

    [Embed(source = "../images/cat.jpg")]
    public var cat : Class;

    [Embed(source = "../images/parrot.jpg")]
    public var parrot : Class;

    [Embed(source = "../images/pig.jpg")]
    public var pig : Class;

    [Embed(source = "../images/quail.jpg")]
    public var quail : Class;

    public function DynamicEmbed() {
    }

    public function getBitmap(id : String) : Bitmap {
        if(hasOwnProperty(id)) {
            var bitmap : Bitmap = new this[id]();
            return bitmap;
        }

        return null;
    }
}
}

The closest you can get with the "dynamic" part, is to create a wrapper class, where you define your images, and you can get them as Bitmap later on by an id.
Unfortunately the properties are public, otherwise the hasOwnProperty function doesn't return true. (If someone finds a better way, please let me know)

See below:

package {
import flash.display.Bitmap;

public class DynamicEmbed {

    [Embed(source = "../images/cat.jpg")]
    public var cat : Class;

    [Embed(source = "../images/parrot.jpg")]
    public var parrot : Class;

    [Embed(source = "../images/pig.jpg")]
    public var pig : Class;

    [Embed(source = "../images/quail.jpg")]
    public var quail : Class;

    public function DynamicEmbed() {
    }

    public function getBitmap(id : String) : Bitmap {
        if(hasOwnProperty(id)) {
            var bitmap : Bitmap = new this[id]();
            return bitmap;
        }

        return null;
    }
}
}
