i dont want to access these movieclip from libaray.
Is it possible to handle/control a movieclip that's on stage through a class? (not the main class)?

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.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at fl.containers::ScrollPane/setScrollDrag() at fl.containers::ScrollPane/draw() at fl.core::UIComponent/drawNow() at fl.containers::BaseScrollPane/get
[code].....
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 have a class called shapeC that only creates a rectangle and then addChild(rectangle);. That class is instantiated on the main timeline. Currently, the only way you can see that rectangle is to add the instantiated class to the stage via addChild(shapeC);. My question is, is there a way that the shapeC class can add the rectangle to the root stage without requireing the instantiated class to be added to the stage?
View 4 Repliesin Adobe tutorials, they suggest to create a class to handle the events (see below the copy/pasted code, and link to page).I was wondering if I have to handle all events with the function handleAllEvents, using if statements to check if the target is the one I want, and the event is the one I want.i.e. if (event.type=="click") && (event.currentTarget == "myId")Should I have a list of ifs (for each target and each event type ?)[code]

for better understanding:
This is my external Class:

Then i have the main .fla file with a movieClip on frame1 called 'terrain'.
When i try my code, the external class does'nt reach the terrain MovieClip :

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).

I have swf with multiple scenes.Controls in each scenes are different. How can I manipulate these controls in different scenes in a single document class for this swf?
View 1 RepliesI'm not sure if it's possible, but can you override a variable of a parent class like you can override a function? I'm trying to create my own event class that can handle the target property. I have a custom imageLoader class, but when it dispatches it's loading complete event:
ActionScript Code: dispatch(new Event("load_complete")); and a listener picks it up, e.target = null where I would like e.target to equal the imageLoader instance that has finished loading.
Does anyone have an answer or a better way to accomplish what I am aiming for?
Im wondering if using the tween class is tough for older computers to handle?
View 3 RepliesHow 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?
can you tell me a simple and clean way to pass the dimension of the stage to another class, imported in my documentclass?
View 2 RepliesI'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).

How to access a display object on the stage in a class which is not a document class?
I am looking for a solution that doesn't involve passing the stage as a parameter to the class.
One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.
I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?

Lets say I have 3 MovieClips on the stage(a Circle, a Square and a Triangle)

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.
Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
This is the code for testClass1:
ActionScript Code:
package
{
import flash.display.*;
[Code].....
So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?

View 8 RepliesI have a MC, instance name "jez_mc" this is inside an MC, instance name "container_mc". container_mc on on the stage.I then have an MC dynamically added to the stage. In this MCs timeline I want to access a variable stored in the class that is linked to jez_mc. This var that I want is named "score"So i figured in my timeline I could use something like:
var _jez_mc:MovieClip;
_jez_mc = MovieClip(root).container_mc.jez_mc;
trace("_jez_mc.score");

I am trying to addChild(displayObject) via a class, and nothing appears when I add it to the stage.

I am trying to remove a MC from the stage from within its own class and trying to keep it so no matter what that MCs object is called it will work. I am using this and it seems to work, but wondering if there is another/better way to do this?

I'm trying to get a small popup (a volume bar) to work from within a class.I made a piece of actionscript code that creates an empty movieClip and draws the bar into it and made it onto a class. The only thing I now have to do to add the bar to a programm, is create an instance of that class. Nothing needs to be added to the stage.The problem I encounter is that I need the bar to stay on top. New movieclips always get higher depths (using getNextHighestDepth()), so that's a problem.Calling swapDepths() for every new movieclip is far too complex and afaik there is no such thing as "bring to front" in actionscript, it only exists at design time, not at runtime.
So I though I'd use 2 layers/movieclips in the timeline, one for the volume bar and one for the rest, and add an empty movieclip to both.This way I know that all children I add to one movieclip will alway lay below anything I add to the second movieclip. (or is there an easier way to accomplish what I need? Levels maybe? I've never looked into levels, I only know they exist when loading a clip)This means I need to add a some extra stuff to the stage at design time, but if this fixes the issue.. ah well.But how can I access that movieclip from within a class? The reference "_root.volumeBarPlaceholder" works from within the main actionscript, but not from within a class because I get the compiler error "There is no property with the name '_root.volumeBarPlaceholder'";
I have a class that places objects on stage with addChild(obj) it allowes me to position objects using pixels( say obj.x = 10; obj.y= 50; ) just fine but if
