Question

I am developing quiz application for practice purpose, using Flash CS5.

At the top of my AS3, I have this :

import flash.net.URLRequest;
import flash.net.URLLoader;

I use it for load XML file.

I wonder, should I import that library, because it’ll compile successfully even I delete that lines?

Thanks.

Answer 1

You are probably placing your code in a frame script, which works with a pseudo import flash.*.* scope.

Import statements do not affect performance or file size and are merely an intrinsic to help the compiler understand what you mean when you are referring to URLLoader.

As a side note, I highly suggest NOT placing code in frame actions and using a document class object and/or external .as files.
