[SOLVED] Strange problem, probably not LoaderMax related.

[mrEmpty]

Hello.

 

I have a strange problem, I'm using LoaderMax in the code but I don't think that's the problem. But as I really can't figure this out, and a simpler version of this code without LoaderMax works, I thought I'd post.

 

I have an empty MovieClip:

 

public var master:MovieClip = new MovieClip();

 

I'm using a for loop to run through an XMLList populated with stuff from an XMLLoader:

 

private function setupMain(event:LoaderEvent):void

{

trace("setupMain");

var panels:XMLList = event.target.content.panel;

trace(panels.length());

 

for (var i:int = 0; i < panels.length(); i++)

{

trace("for start");

var box:NavBox = new NavBox(800, 450);

master.addChild(box);

box.x = box.width * i;

box.y = 100;

trace(box.x);

trace(box.y);

}

}

 

The problem is, the instances of box do not appear. If I add them to the stage they do, but if I add them to master they don't. If I trace the positions it appears as if they are added to the display list, but they don't show up.

 

Now, if I ignore the entire loading thing this problem goes away. But I don't think LoaderMax is the issue at all.

 

Complete code just in case it helps:

 

package  {

import flash.display.MovieClip;
import flash.display.DisplayObject;
import flash.text.GridFitType;
import mx.core.BitmapAsset;
import flash.events.MouseEvent;

import com.greensock.loading.LoaderMax;
import com.greensock.loading.ImageLoader;
import com.greensock.events.LoaderEvent;
import com.greensock.loading.XMLLoader;
import com.greensock.BlitMask;
import com.greensock.TweenMax;

import com.fingerpuk.ui.NavBox;


public class Treasures03 extends MovieClip {

	//embed the background image
	[Embed(source="assets/Grid.png")]
	const Grid:Class;

	//create master container
	public var master:MovieClip = new MovieClip();
	//create my BlitMask
	private var bMask:BlitMask = new BlitMask(master, 0, stage.stageHeight, stage.stageWidth, stage.stageHeight);


	public function Treasures03() {
		init();
	}

	private function init():void
	{
		//configure the BlitMask
		bMask.smoothing = true;
		bMask.wrap = true;

		//load the background image
		var grid:DisplayObject = new Grid();
		addChild(grid);

		//configure the master
		addChild(master);
		trace("master added");

		//load and parse the config xml
		var xmlLoader:XMLLoader = new XMLLoader("assets/config.xml", {onComplete:setupMain});
		xmlLoader.load();

		//set up test listener on stage, delete later
		master.addEventListener(MouseEvent.MOUSE_DOWN, testBlit);
	}


	private function setupMain(event:LoaderEvent):void
	{
		trace("setupMain");
		var panels:XMLList = event.target.content.panel;
		trace(panels.length());

		for (var i:int = 0; i < panels.length(); i++)
		{
			trace("for start");
			var box:NavBox = new NavBox(800, 450);
			master.addChild(box);
			box.x = box.width * i;
			box.y = 100;
			trace(box.x);
			trace(box.y);
		}
	}

	private function testBlit(event:MouseEvent):void
	{
		trace("testBlit");
		TweenMax.to(master, 3, {x:-3000, onUpdate:bMask.update});
	}
}

}

I think your master should be should have boxes in it before you create a BlitMask for it.

in the first example I didn't see that master was on the display list. i didn't see addChild(master).

 

so even though you do master.addChild(somebox);

if master isn't added to the display list... you won't see any boxes.

OK. I've moved the creation of the BlitMask to after the for loop:

 

private function setupMain(event:LoaderEvent):void
	{
		var panels:XMLList = event.target.content.panel;

		for (var i:int = 0; i < panels.length(); i++)
		{
			var box:NavBox = new NavBox(800, 450);
			master.addChild(box);
			box.x = box.width * i;
		}		
		confMaster();
	}

	private function confMaster():void
	{
		addChild(master);

		bMask = new BlitMask(master, 0, stage.stageHeight, stage.stageWidth, stage.stageHeight);
		bMask.smoothing = true;
		bMask.wrap = true;
	}

 

So now I'm loading the XML, creating an XMLList, using that to create my instance of NavBox and adding them to master. I then run a function (confMaster) that adds master (which has 5 instance of NavBox in it) and creates the blitmask. Still not joy though

I solved it, it was the BlitMask.

 

The correct code is:

 

bMask = new BlitMask(master, master.x, master.y, master.width, master.height);
