RE: [flexcoders] Re: how to start with a dynamic actionscript class instead of mx:Application?

[Alex Harui]

I'm not clear you can use this sequence to startup a Flex app.  You
might be able to wire it in as a replacement for a downloadProgressBar.

 

You can make the main app dynamic by subclassing

 

public dynamic class BrianApplication extends Application

 

but I still don't think this is going to work.

instead of mx:Application?

 

Well, here's one of the classes from their API doc. I think it's an
example, but I tried calling this in my preloader attribute in
mx:Application and it errored with a null error on the
loaderInfo.addEventListener line. I tried to put my main mxml file in
the MAIN_CLASS.

The properties look to be the 'id' and 'res', although there is an
additional one for AS3, called 'clip' and from the examples it looks
like it's supposed to be a MovieClip class.

>From their docs, the important line appears to be the 

MochiAd.showPreGameAd(opts);

near the end. They generate code for this based on your game and
resolution, and tell you to put that in your 'main class' as they call
it. Their generated code looks something like

MochiAd.showPreGameAd(clip: root, id: "someHexString", res: "800x600");

Here's their example Preloader:

package {
import flash.display.DisplayObject;
import flash.display.MovieClip;
import flash.events.IOErrorEvent;
import flash.utils.getDefinitionByName;

// Must be dynamic!
public dynamic class Preloader extends MovieClip {
// Keep track to see if an ad loaded or not
private var did_load:Boolean;

// Change this class name to your main class
public static var MAIN_CLASS:String = "Test";

// Substitute these for what's in the MochiAd code
public static var GAME_OPTIONS:Object = {id: "test",
res:"550x400"};

public function Preloader() {
super();

var f:Function = function(ev:IOErrorEvent):void {
// Ignore event to prevent unhandled error exception
}
loaderInfo.addEventListener(IOErrorEvent.IO_ERROR, f);

var opts:Object = {};
for (var k:String in GAME_OPTIONS) {
opts[k] = GAME_OPTIONS[k];
}

opts.ad_started = function ():void {
did_load = true;
}

opts.ad_finished = function ():void {
// don't directly reference the class, otherwise it
will be
// loaded before the preloader can begin
var mainClass:Class =
Class(getDefinitionByName(MAIN_CLASS));
var app:Object = new mainClass();
parent.addChild(app as DisplayObject);
if (app.init) {
app.init(did_load);
}
}

opts.clip = this;
MochiAd.showPreGameAd(opts);
}

}

}
