mxml use .swc library file to addChild components to panel/canvas/etc and run code for game

Question

I am using flash builder to build a flex project, and I am just getting into mxml. I have a flash game that I made in Flash Professional CC - I published an swc file from Flash CC - all of the symbols are exported in 1st frame, and exported for actionscript (in Symbol Properties) - They reside in the same folder as the swc file.

In Flash Builder 4.6 - I added the swc file to the library path so that I could access the symbols. Here is my code:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <!-- <s:VGroup>
        <s:TextArea id="textArea" width="300" height="300"/>
        <s:Button label="Connect" click="onConnectClick()"/>
        <s:Button label="Send" click="onSendClick()"/>
        <s:Button label="Disconnect" click="onDisconnectClick()"/>
    </s:VGroup> -->
    <fx:Script>

I have no errors, but it comes up as a blank page (it is a game where there is an avatar and an enemy - and the avatar tries to avoid the enemy as it moves down the screen).

What am I doing wrong? Do I need to embed the swf file for the game too?

Also - you can ignore all of the socket stuff - that all works fine (I have already tested it, but I am trying to integrate socket.io-flash with my game). Thanks.

Try embedding your SWF file like this:

[Embed(source="foo.swf")]
[Bindable]
public var game:Class;

You typically embed a Flex application when you do not require the embedding application to interact with the embedded application. If the embedded application requires interactivity with the embedded application, you might consider implementing it as a custom component, rather than as a separate application.

[Edited]

Otherwise do:

[Bindable]
public var loadedSM:SystemManager;

// Initialize variables with information from
// the loaded application.
private function initNestedAppProps():void {
     loadedSM = SystemManager(myLoader.content);
}

.
.
.

<mx:SWFLoader id="myLoader" width="100%" height="100%"
source="foo.swf"
creationComplete="initNestedAppProps();"/>

Im not 100% sure this is what you are looking for, and this solution would be a bugger to adapt. Sorry if i couldnt help

mxml use .swc library file to addChild components to panel/canvas/etc and run code for game
