External Config file in Actionscript 3

问题


I need to be able to load external configuration files into my flex app. I've read that this is possible using embeds, so long as the mimeType is set to application/octet-stream.

package learning {
    import org.flixel.*;
    public class PlayState extends FlxState {
        [Embed(source = "../../data/tiles.png")] private var _tiles:Class;
        [Embed(source = '../../data/map.txt', mimeType = "application/octet-stream")] private var ExternalMapData:Class;

        public var txt:FlxText;
        public var player:FlxSprite;

        override public function create():void {
            bgColor = 0xffaaaaaa;
            super.create();
        }

        override public function update():void {
            super.update();
        }
    }
}

When I compile this using mxmlc, it compiles successfully with no errors. When I run the SWF, it loads all the Flixel menus then hangs.

If I comment out the [Embed(source = '../../data/map.txt' line, it compiles and doesn't hang.

Why is this embed causing a freeze?

Version info for mxmlc:

Adobe Flex Compiler (mxmlc)
Version 4.0.0 build 14159

EDIT

It turns out errors weren't being displayed properly, but this is what I'm getting from attempting the embed:

VerifyError: Error #1014: Class mx.core::ByteArrayAsset could not be found.

Google turns up a bunch of people with the same problem, but no apparent solution.

import mx.core.ByteArrayAsset; ByteArrayAsset

doesn't help either.


回答1:


Aha! It turns out the solution was very simple - runtime shared libraries weren't being statically linked into the swf, and the path wasn't being set properly for access during runtime. The solution is simple:

Either modify flex-config to say

<static-link-runtime-shared-libraries>true</static-link-runtime-shared-libraries>

or manually pass in the parameter to mxmlc

mxmlc -static-link-runtime-shared-libraries=true -debug=true Main.swf -- Main.as

I'll answer this one with my answer to another question:

[Embed(source = "ExampleText.txt", mimeType = "application/octet-stream")]
protected var AAAAAA:Class;

var tmp:ByteArray = new AAAAAA();
var result:String = tmp.readMultiByte(tmp.bytesAvailable, tmp.endian);
