Accessing resources in loaded/external SWFs

It still asks me about parent.parent not being inside the DisplayContainer or something like that despite my checking that it's null. Another question I have is it may not be worth it because I wont be able to trigger or access public variables in the parent swf file right? For example will I be able to do something like parent.parent.changeBackground(). I don't understand scoping or the OO elements yet as I've never had to do something like this. It's mind-boggling that it's not easier than this.

My thoughts on doing this were that it is relatively easy to contain "modularised" pieces of functions/codes in sub-SWF files that can be imported to effect functions contained in a parent SWF. What seems to be clear though is that each SWF contains declarations and logics from the docs (thus indexPage contains logics that icMain already contains. This is basically what I'm doing with my Tweener classes - yeah).

Obviously I'm super confused. heh. :-/

Hi there,

Wow thank you very much for all this. I'll definitely give it a go later on tonight. I have 4 other things I need to finish right now :-/ ack! Though hold on, your response was curious not sure if I explained it correctly. Whenever I import an as file into my indexPage it WILL NOT compile code from that source file into the new page thus making it a larger footprint. We're simply importing it to satisfy the compilers need to declare the type.

Also regarding the parent.parent reference issue. Mind helping poor me explain why it's reading compile errors as well. The person in the other thread I presented seemed to have got it working...strange. I might want to use that method in the future, so it would be useful if I understand what's going on there as well.

Thanks!!!

Hey there,

Yeah I noticed that I needed to add it loadComplete AFTER I posted the code :-/ I added it all correctly I believe but I'm getting compile errors:

On icMain.as - 1046: Type was not found or was not a compile-time constant: indexPage.
On index.as - 1046: Type was not found or was not a compile-time constant: icMain.

I thought I could just ignore them but the swf doesn't run properly :-/

Note that I was getting this error too: 1114: The public attribute can only be used inside a package. so I moved the function outside the construct function right after the package declaration. Here's what I got for index.as

package {

import flash.display.*;
import caurina.transitions.Tweener;
import caurina.transitions.properties.CurveModifiers;

public var _icMain:icMain;

public class indexPage extends Sprite
{

public function set mainSWF(mainSWF:icMain):void {
_mainSWF = mainSWF;
}

public function indexPage():void
{



}
}
}

As for having both .as in the same folder, erm...what do you mean I have to import them? My index.fla and index.as are in an index/ folder...right now.

First, you need a loadComplete function in your icMain class to get called after the swf is loaded. You set up that relationship already in this line:
indexLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);

so you need this:
private function loadComplete(event:Event):void
{
}

then, move these functions into the loadComplete function as you have to wait until the swf is loaded before setting the reference:
var indexPage:indexPage = indexLoader.content as indexPage;
indexPage.icMain = this;


In your indexPage class, you need to move your set mainSWF function outside of the indexPage function. Also, the type of object you are passing, according to your code, should be icMain.

So, instead of this:

public function indexPage():void
{
public function set mainSWF(icMain:MainSWFDocumentClass):void {
_icMain = icMain;
}
}

Do this (notice I changed the name of your variable to avoid name conflict. using the convention of starting class names with a Capital letter would help too):

private var _mainSWF:icMain;

public function indexPage():void
{
}
public function set mainSWF(mainSWF:icMain):void {
_mainSWF = mainSWF;
}


Here is the rewritten icMain class:

package
{
public class icMain extends Sprite
{
public function icMain():void
{
var indexRequest:URLRequest = new URLRequest("index/index.swf");
var indexLoader:Loader = new Loader();
indexLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
indexLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
indexLoader.load(indexRequest);
}

private function loadComplete(event:Event):void
{
var indexPage:indexPage = indexLoader.content as indexPage;
indexPage.icMain = this;
}
}
}

And here is your rewritten indexPage class:

package {
public class indexPage extends Sprite
{
private var _mainSWF:icMain;

public function indexPage():void
{
}
public function set mainSWF(mainSWF:icMain):void {
_mainSWF = mainSWF;
}
}
}
