在 ActionScript 3 嵌入语句中使用变量
我在名为 asset/images/pieces 的目录中有一组图像，名为 1.png、2.png 3.png 等。我的问题是，如何使用 Action Script 3 中的随机变量加载这些图像？
我可以执行下面输入的操作吗？
/** Typical Embed Statement **/
[Embed(source="image/path/here")]
/** Modified **/
var path_name = "image/path/here/";
[Embed(source=path_name)]
I have a set of images within a directory called assets/images/pieces named 1.png, 2.png 3.png etc. My question is, how can I load these images using a random variable within Action Script 3?
Could I do what I have entered below?
/** Typical Embed Statement **/
[Embed(source="image/path/here")]
/** Modified **/
var path_name = "image/path/here/";
[Embed(source=path_name)]

我的理解是你不能这样做，因为嵌入标签在编译时执行，所以 path_name 还没有分配给它的值，你会得到一个错误：
要在运行时处理嵌入，你可能必须使用 URLLoader。但请记住，它是异步的，您必须等待 COMPLETE 事件才能使用图像。

My understaning is that you can't do it because the Embed Tag executes at compile time so path_name doesn't have a values assigned to it yet and you will get an error:
To handle the embed at run-time you will probably have to use URLLoader. But keep in mind it is asynchronous and you will have to wait for a COMPLETE event before being able to use the image.
