ActionScript 3.0 :: Reference Objects On Stage / Frame From Document Class
Jun 8, 2011I'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.

ActionScript 3.0 :: Getting An Error That They Cannot Reference The Stage/ Stage Is Null?
Jun 9, 2010I am currently working with a contractor company that is hosting a flex based website. They are putting the swf files that I have developed into their flex site.The issue that I am having is that within my swf file I need to reference the stage.I do this by "MovieClip(parent).stage"... I do not use the keyword "root", I just reference my swf's root through however many "parent"s i need. It works fine when I publish on my own, outside of their flex site. When it is used in the flex site, they are getting an error that they cannot reference the stage/ stage is null. It is vital that I am able to reference the stage of my swf.

Jul 24, 2010I have drawn colored rods which I have placed in the library and have put one of each on the stage with instance names likeblueRod_mc, etc.I place them around with time-line code like
blueRod_mc.x = 300.0;I have now created an Actionscript class called Problem.I build a new object from Problem which I have called Riddle.But when I put blueRod_mc.x = 300.0 in a method (of Problem),I get the message that blueRod is not accessible.So I triedstage.blueRod_mc.x = 300.0;That did not work either.

ActionScript 3.0 :: Reference Objects In Multiple Scenes?
Sep 26, 2011How do you refer to specific named instances of objects (buttons, movie clips, text fields, etc.) in different scenes? I made two scenes with button1 on scene 1 and button2 on scene 2. My code is below. The button2.addEventListener line gives the error "cannot access a property or method of a null object reference." Removing that line removes the error and button1 switches scenes. What's the proper way of referring to button2?

View 3 RepliesFlex :: AS3 - Removing Objects By Array Item Reference
Jan 2, 2010I am trying to add some Sprite objects as the contents of an array, and I would like to be able to "clear" them from the stage. I would assume that if there are loaders involved, I need to do
_imgArray[i].close();
_imgArray[i].unload();
And if I am using a sprite, I can do:
removeChild(_imgArray[i]);
None of the above work.
Currently I try:
for(i = 0; i < _localXML.length(); i++) {
var tmp:BMLink = new BMLink(_localXML[i], _bw, _bh, i);
_imgArray[i] = tmp;
_imgArray[i].x = (_bw + _mainpad) * i;
_base.addChild(_imgArray[i]);
But this doesn't work.
The class instances that are populating the array are all extending sprite, but they have their own individual loaders inside w/ progress events etc.

I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true);

var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250);

ActionScript 3.0 :: Unable To Reference Child Display Objects Of Clip Imported From Library?
Jun 17, 2009PBar contains two SimpleButtons (pBarProgress and pBarLoaded) and a MovieClip (pBarBg).I import pBar from the library like this:private var pBar:PBar = new PBar();and add it to a container MC on the stage like this:containerMC.addChild(pBar);Up to this point, everything works great. I can see pBar and its children on the stage when I run my movie. But then I want to start referencing and manipulating pBar's child objects, but nothing I do works.

Sep 30, 2010I have 9 MovieClips on stage (p1, p2, p3...), different colors and sizes. I have one AS3 class -Snake- that as an instance is supposed to duplicate one of these MC's as a Shape. The reference to the specific MC is supposed to be on the constructor method. These instances are supposed to be triggered from one global Enter.FRAME event.
My question: How can I refer a distinct MC from within a class? I ask this because this MC will be dynamic and its properties ever-changing (position and color). I know this can be solved by adding distinct Enter.FRAME listeners per instance, but I'd rather avoid bad practices.

ActionScript 1/2 :: Reference The Stage From Within A Class?
May 25, 2010I'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'";

View 6 RepliesActionScript 3.0 :: Reference Stage From Within A Subclass?
Aug 9, 2011I'm playing around with some classes from my Learning AS 3.0 book in an attempt to understand them. I have a main (document) class, and a class called NavigationBarXML.
Because the buttons for the nav bar are all set up in the subclass NavigationBarXML, I would like to position the nav bar relative to the stage (think btn1.x = stage.stagewidth - 50) from within this class. I understand that you cannot deal directly with the stage from a subclass and that you must add it to the display list before you can reference the stage from within this class.
How would I set up the main class so that I can reference the stage from my subclass so that on browser resize, my nav bar is positioned relative to the stage?
