I've read a lot of different articles and discussions about the null object reference that occurs when a loaded swf tries to access the stage before it has been added to the display list.
And I'm wondering, "Is there seriously no way to handle this issue without modifying the SWF being loaded?" Even with Flex or otherwise?
I'm trying to get some things done but run once in a while, well at least, into some issues.Here is one:
I have an swf that is an image viewer/browser that has references on same level, an ImageProperties.xml and some folders full of small jpeg tiles.I actually have a few of these, each in its own folder.Above these folders I have another swf that is the main one, and I am loading from there the other ones with the code pasted at end of this post.
This works if I replace the URLRequest by just the name of the swf to load and I put the main swf with the loader function and the loaded one at same level. But if I leave URLRequest going one level deep "16/xxx.swf" and have the loader swf one level up then it loads the viewer but doesn't show the image.

I'm trying out the preloader method shown on [URL] and its working fine until I use any reference to 'stage' in the loaded swf.
My loaded swf works fine if I test it on its own, but when I run the preloader which loads it, I get an error 1009 - I have found out (by a series of elimination) that its as soon as I reference 'stage' in the document class of the loaded swf
I'm having a problem with a .swf which when loaded into another .swf has its constructor function ignored
when i'm running local it works fine, but when theres a real loading the constructor doesnt run, also making timeline code ignored ( since timeline code is just addScript call in the clip constructor)
anyone else has had this problem?? same problem happens either using Loader class or BulkLoader, also happens when simulating download in the IDE
I'm making a kind of image showcase, what has a fluid width and height, depending on browser window dimensions. Everything is okay, I have other kind of issue: in constructor function in this gallery class I can't use stage property, I have to get it from main class. Why Flash treats me this way and how I can avoid this currentStage variable?
Main code:
package dev {
import flash.display.Sprite;
import flash.display.StageScaleMode;
import flash.display.StageAlign;
import flash.display.MovieClip;

For a project i am needed to move a vast range of movieclips over time on the stage.I thought to write a class to tackle it. my little class experience tells me you can't acces the stage in the constructor. well great, just add an eventlistener for the ADDED_TO_STAGE. I wonder how to pass the stage.stageWidth to a custom class as an optional parameter.[code]

View 1 RepliesI have a flash movie I'm externally loading into my SWF. It isn't mine. I'm trying to pause the swf, but I can't and I don't know how the SWF works because it isn't mine. I was thinking about maybe creating a bitmap of it, but I can't do that because I don't think you can create bitmaps at runtime of moviing movie clips. Is there a solution to my problem

I have encountered a problem when I need to load a third-party flash in to my flash. The flash is written in an erroneous way, it access stage in the main class constructor. I know that a display object can not access to stage property until it is added to stage, and certainly can not access to stage in its main class constructor. I observe 2 cases:
- If the flash run STANDALONE, it run well: I don't know why stage is assign before its constructor
- If the flash is LOADED by my flash, it yield null reference exception as expected
In the second case, if the third-party class remain unchanged, is there a workaround that load flash?
I have a Sprite in my library that is linked to a class (lets call it SomeClass), and i put on stage in Flash, and name the instance someClass. In my Main.as i then write:
var myClass:SomeClass = this.someClass;
SomeClass.as has a constructor with the same name as the class, however it require an argument. How do I pass that to the class when I made an instance of it directly in Flash by dragging it to the stage? (instead of the usual ... = new SomeClass(arg); )
I tried something like this:
myClass.SomeClass(arg);
But that gives me this error:
1061: Call to a possibly undefined method SomeClass through a reference with static type SomeClass.
I have created a XML driven shell where I'm calling external SWF files reading from the XML.ome of the SWFs has SCROLLPANE from the component panel of Flash is added on their respective stages. Now if I'm running those files individually, they are working fine. But it is loaded in the shell the below issue is coming.

Is it possible to handle/control a movieclip that's on stage through a class? (not the main class)?
View 4 Replieswhen to use this in a classes?is there any specific rule?is it wrong to use this when you want to just access the stage that way?or is it better to pass the reference to the stage in the class constructor?
View 5 RepliesIs it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip {
public function CustomRectangle(width:int, height:int) {
this.width = width;
this.height = height;
}
}
my movie is linked to an external class called game, and in the game cosntructor I am trying to access instances on my stage. I have tried MovieClip(root).instancename, root.instancename and even tried adding an event listener to listen when the movie is done loading because I thought maybe it was because the instances on the stage weren't created before the constructor is ran. This is the main class, shouldn't it be easy?

By dynamically I mean using
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);

I'm creating a scrollbar gallery from a tutorial on this site. Though I've completed the tutorial, and customised the gallery to my own needs, however I'm trying to make a very small change to it - and no matter what I do, keep running into problems. I'm trying to replace the rectangular handle with my own customised handle - a (20 x 20) 'circular' png image that I've imported into Flash, made a graphic and stored in the library (though I understand it can be imported using actionscript, like the other images in the gallery).
[Code]....
How does flash player handle objects when they are no longer on the visible stage? Is the graphical data still in memory? Does hittestobject/point consider them? Are enterframe and interval events still running?
In AS2 I would hold metaobjects (minimal x,y,width,height data) that would delete/create movieclips as the screen scrolled. Is this still a correct approach in AS3? If not, is there anything I can do to offstage display objects that improves efficiency, assuming around 400 are created initially?
There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.
I am trying to reference to top level (stage) width and height of the main stage for the placement of something located inside a movieclip on the stage.
My code is:
Code:
my_loader.x = (stage.stageWidth - my_loader.width)/2;
my_loader.y = (stage.stageHeight - my_loader.height)/2;
But this seems to just relate to the width/height of the mc that my_loader is nested in...
I have tried the following and had no luck:
stage.stage.stageWidth
root.stage.stageWidth
parent.stage.stageWidth
MovieClip(root).stage.stageWidth
- I have A.fla.
- A.fla includes buttons, movie clips and also B.swf is loaded in A.fla using a LOADER
- i want to access elements in A.fla, from the actionscript codes inside B.fla to modify those movie clips and buttons based on actions going on in B.swf
for instance, lets say there is a button X in A.fla, and there is a button Y in B.fla, B.swf is loaded into A.fla, and I want the button Y to erase button X when clicked.
general question: accessing elements in a stage, through a SWF file loaded into that stage.
An external swf is loaded using this code...

The problem is that even though this external movie covers the whole stage, My mouse can still "see" buttons that are on the stage, and I can click them. I don't want to be able to click the buttons through my external movie.
I'm making a mockup for a client and I need to Load the .swf with the exact stage size so the graphic elements do not float outside the loaded movies stage area. [URL]Basic load code I'm using...
Actionscript Code:
import flash.display.*;var adLoader1:Loader = new Loader();adLoader1.load(new URLRequest("100828_budlight_texas_fight_728x90_jn.swf"));adLoader1.x = 313;adLoader1.y = 162;addChild(adLoader1);var adLoader3:Loader = new Loader();adLoader3.load(new URLRequest("100828_budlight_texas_fight_300x615_jn.swf"));adLoader3.x = 738;adLoader3.y = 0;addChild(adLoader3);
I have a root stage, and a MC that is called from the root stage.Now from that MC, i will called in another MC2, and I wanted to placed the MC in the center of the stage. The reason I could not use normal ADDED_TO_STAGE at MC and define the center is because MC is not place in the exact position of the root stage (as in x, y=0). So if I would target MC2 at MC stage center, it would not be the exact center of the root stage/screen.How can I called the root stage properties rather than adding MC2 into the stage?
View 1 RepliesFor the scenario lets consider Car to be the highest SWF(stage) inside I load tyres. Inside tires I have rims. Now if the rims need to be positioned relative to the stage (car body) how can I do that? Inside rims if I write stage and load it results in an error.

I'm still pretty new to XML and Loader's. So I tried making a preloader by first catching the URL of the movie that needs to be loaded from a swf, and then loading that swf. [code]...
