Question

I've hit a very complicated brick wall

I'm sorry that I can't be more descriptive in my title, but I think I stuck my neck too deep and now I can't tell what is not working. I'm going to atempt to be as clear and concise as possible in my explanation, but sorry if I do something completely wrong or don't understand it fully.

Basically, what I am trying to do is load a bunch of .swf files that each extend the class "Plugin" from a folder called "plugins", and then execute specific code from them at specific times.To do this properly, I'm making a test plugin that is using a .swc library from the main program to extend "Plugin". Whenever I want to instantiate something that extends "Plugin", I have to give it a reference to my main program. However, here is where the problem occurs: when I try to load and then instantiate the plugin, I get an error saying that my main class is not my main class:

TypeError: Error #1034: Type Coercion failed: cannot convert me.bleachisback.cocmod::CoCMain@51b31f1 to me.bleachisback.cocmod.CoCMain.

I've been trying to fix this problem for the past week, and I just can't figure it out. I have a feeling it might have something to do with how I use the .swc file, but I can't tell if that is true/how to fix it because there is barely any documentation out there on it, especially in normal Flash and not Flash Builder.

Below is my source and how I attempted to get it to work:

https://mega.co.nz/#!Pdtn2SiB!ISszSDdGkaZyw6HB1ntRaVD2kckmnAxDeGsMTqS9SVw (A rar file containing my source)

There are 10 main files in the rar:

System/CoCMod.fla - The fla file for the main program

System/CoCMod.swc - The swc file for the main programe, and the library my plugin is using

System/CoCMod.swf - The swf for the main program

System/me/bleachisback/cocmod/CoCMain.as - The main class for the main program

System/me/bleachisback/cocmod/Plugin.as - The "abstract" class that every plugin should extend

System/plugins/TestMod.swf - The swf for the plugin, same as below. Does not do anything unless loaded by the main program.

Test Mod/TestMod.fla - The fla file for the plugin. Has actionscript on frame 1.

Test Mod/TestMod.swf - The swf for the plugin, same as above.

Test Mod/main.xml - Embedded into TestMod.swf, contains information about the mod.

Test Mod/plugin/bleachisback/testPlugin/TestMain - The main class for the plugin - extends Plugin.

This is how I export the .swc file (in CoCMod.fla):

And this is how I reference it in TestMod.fla:

What should happen is just a simple "blah" appears in the console, but for as few lines of code as I have, it doesn't want to work. Can someone tell me what I'm doing wrong?

you have to publish your swc first.  then publish the swf that uses that swc.  then test.

It's an applicationDomain or securityDomain issue. Essentially, you have multiple swfs loading in the same Class, but they're seen as different Classes because they're not in the same applicationDomain or securityDomain. That should give you enough background to go find the solution with a web search--I always have to look it up myself.

I thought it was an applicationDomain issue, so I tried loading it into my current application domain:

var loader:Loader = new Loader();
var url:URLRequest = new URLRequest(file.nativePath);
loader.load(url, new LoaderContext(false, ApplicationDomain.currentDomain));
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, pluginLoadingComplete);
  
                    private function pluginLoadingComplete(e:Event):void {
                              trace(e.target.applicationDomain == ApplicationDomain.currentDomain); //outputs false
                              plugin.initialise(this, desc.name[0], desc.description[0], desc.version[0], desc.author[0]); //error here
  
                              plugin.onEnable();
                    }

But when I do this, the trace outputs false, even though I esentially copied and pasted it from the adobe documentation.

Also, I am publishing the swc before I publish my plugin swf.

there is no plugin swf. it's TestMod.swf that uses the swc.

anyway, that's a convoluted setup and it's causing you problems.

what are you trying to do?

Enable debugging in your publishing option and post the Line of Code that causes the error

It happens in line 38 of CoCMain.as:

        private function pluginLoadingComplete(e:Event):void {
            var plugin:Object = new e.target.content.mainClass();
            var desc:XML = new XML(new e.target.content.description);
            trace(e.target.applicationDomain == ApplicationDomain.currentDomain); //outputs false
            plugin.initialise(this, desc.name[0], desc.description[0], desc.version[0], desc.author[0]); //error here
            
            plugin.onEnable();
        }

I´m guessing you attach the event.complete listener to a Loader Object.

Make sure you instantiate the loaded swf properly:

from

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/LoaderInfo.html

For a Loader object that has not called the load() or loadBytes() method, or that has not sufficiently loaded, attempting to access many of the properties of the contentLoaderInfo property throws an error.
