I have a need to be able to load legacy AS2 SWF's into a new AS3 project. I
know that this is not readily possible, because you can only communicate
between the two via the LocalConnection class. So, what I have done is to
create an AS2 proxy SWF. This SWF will handle the loading of all legacy SWF's
and act as a middleman to pass the function calls between the pre-compiled SWF
and the new SWF using the LocalConnection class. The new SWF also needs to be
able to load AS3 SWF's, though.

Because of this, I have the need to detect the AS version of the loaded SWF.
If 1 or 2, then change the source to the AS2Proxy.swf, if 3 then simply load it.

I have written the following code. My problem comes in when the init event
fires. Regardless of the compiled version of the loaded SWF, it always traces
3 as the AS version.



simulation.source = ModulePath+curPageXML.attribute("Path").toString() ;

simulation.addEventListener(Event.INIT,doInitSim);

function doInitSim(evt:Event):void {
trace(simulation.loaderInfo.actionScriptVersion); // always traces 3
if(simulation.loaderInfo.actionScriptVersion > 2){
simulation.addEventListener(Event.COMPLETE,doVideo Ready);
}else{
simulation.source = InterfacePath+"AS2Proxy.swf";
simulation.addEventListener(Event.COMPLETE,doProxy Ready);
}
}

Alright, I solved this problem, only to come up with many more.

To solve this problem, I needed to point to the loaderInfo object of the
UILoader's content. So: simulation.content.loaderInfo.actionScriptVersion.

Now the proxy loads correctly, but I start getting errors immediately. Let me
paste some code to show the next steps:

First off. I immediately receive a StatusEvent error, though the path gets
sent into the proxy and loads correctly.

Next, when the complete event fires in the AS2 SWF - it sends a completion
back up to let the AS3 SWF know that it finished (and any handling that needs
to happen at that point.) I receive the following error:
Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095:
flash.net.LocalConnection was unable to invoke callback loadSwf.
error=ReferenceError: Error #1069: Property loadSwf not found on
com.applied.flash.events.AS2Connect and there is no default value.

This is the AS2Proxy.swf code.

var connection:LocalConnection = new LocalConnection();

connection.connect("AS3Connect");

if(path){
proxyLoader.contentPath = path;
}

connection.loadSwf = function( path:String ){
proxyLoader.contentPath = path;
}

proxyLoader.complete = function(){
connection.send("AS3Connect","swfLoaded",true);
}

function completion():Void {
connection.send("AS3Connect","swfLoaded",true);
}


This is the AS2Connect class for hearing what is sent from the AS2 SWF

package com.applied.flash.events {

public class AS2Connect extends Object {

public function swfLoaded( value:Boolean ):void {
trace(value);
}
}
}

Finally, this is all of the related code in the AS3 swf

var connection:LocalConnection = new LocalConnection();
var myIP:String = connection.domain;
connection.client = new AS2Connect();
try{
connection.connect("AS3Connect");
}catch(e){ }

simulation.source = ModulePath+curPageXML.attribute("Path").toString() ;
contentPlayers.addChild(simulation);
simulation.addEventListener(Event.INIT,doInitSim);

function doInitSim(evt:Event):void {
if(simulation.content.loaderInfo.actionScriptVersi on > 2){
simulation.addEventListener(Event.COMPLETE,doVideo Ready);
}else if(simulation.source != InterfacePath+"AS2Proxy.swf"){
simulation.source = InterfacePath+"AS2Proxy.swf";
simulation.addEventListener(Event.COMPLETE,doProxy Ready);
}
}

function doProxyReady(evt:Event):void {
connection.send("AS3Connect","loadSwf",
ModulePath+loadedXML.Pages.Page[tree.selectedIndex].attribute("Path").toString()
);
connection.addEventListener(StatusEvent.STATUS,doS tatus);
}

function doStatus(evt:*){
trace(e);
}
