ActionScript 3.0 :: Accessing The Stage Property?

Nov 28, 2011

I am having a problem referring to stage properties, where I am trying to e.g. obtain a third of the width of the stage. My code keeps throwing up the "Cannot access a property or method of a null object reference." I have found a few things from a search online, but haven't been able to work through it yet.

I should also say that I am working in flash and have made a movieclip with a movieclip inside (which is to be used as a roll-over menu for image thumbnails). The instance name of the 'parent' movieclip is "galleryPane"; and mc inside has an instance name "thumbnailsContainer" .Here is my code:

ActionScript 3.0 :: Accessing Property Placed On Stage Using External Class?

Apr 23, 2010

How can I access objects and modify their property that is ALREADY placed on the stage using external classes (AS file)? I 'm a newbie of AS3 and followed some tutorials about AS3 not long ago. For I learned scripting in AS3 can be done using AS file rather than script on Timeline. But I have a question. How can I "find" and "modify"the objects on the stage, or inside a MovieClip , in AS3?

For example, I have a file call Stage004.fla which have no document class linkage. I place the MovieClip "StageMain" which links the Stage004.as on the stage. StageMain has a textfield in it named "textFieldStage001". The Stage004.as is ran using "Event.ADDED_TO_STAGE" since StageMain is on the stage. I create another AS file WindowRename , to test can I modify the text in "textFieldStage001".

Then the famous error #1109 occurred.
"1119: Access of possibly undefined property textFieldStage001 through a reference with static type Class."

ActionScript Code:
package {
import flash.display.Stage;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.MovieClip;
public class Stage004 extends MovieClip{

ActionScript 3.0 :: Error Accessing Property Of Loaded Swf?

Oct 11, 2010

I am getting the following error when I importmy swf onto my main stage: TypeError: Error #1009: Cannot access a property or method of a null object reference.

at ButtonsMenu_fla::buttonsScrollingMenu_1/ButtonsMenu_fla::__setProp_sb1_buttonsScrollingMen u_ScrollBarComponent_1()

On it's own the carousel works fine, it's only when I import it that it throws an error, all of the components within the carousel work fine (the images are highlighted on mouse over, the onclick code for the thumbs runs the right functions) it's just the scrolling that doesn't work.I've tried removing the references to stage from the loaded swf but I still get the same errors.I'm fairly new to flash but I'm finding the error messages to be fairly unhelpful at the best of times, I've attached the swf I'm trying to load in in a zip

ActionScript 3 :: Flash Bugs When Accessing Property In Loaded SWF

Apr 10, 2011

In main:

ActionScript 3.0 :: Accessing A Property Of A Movieclip That Has Been Stored In An Array?

Apr 20, 2011

I need to create an Array of movieclips so that I'm able to read / modify / add its properties. I thought the best solution was to create an Array of strings with each movieclip's name and then using this to convert the string to an expression, but I don't really know what to do when I want to access one of its properties. Here's my code:

room.objects = ["mcObj1", "mcObj2", "mcObj3"]

ActionScript 3.0 :: Accessing Property Of Child Of A Display Object

how to access a property of a child of a DisplayObject.

within a class i have an object with the variable name: btnLMain i have assigned it a name property: btnLMain.name = "btnLMain"; btnLMain also has a property: btnLMain.clickNum = 0; // thats the one i need to access when i instantiate the class (btnL) containing this code in the parent class i need to access the property "clickNum" so i did this:

var dispObj:DisplayObject = btnL.getChildByName(btnLMain);
displayObj.clickNum++;

but then i get the error: 1119: Access of possibly undefined property clickNum through a reference with static type flash.display:DisplayObject.

so then i reviewed documentation and from what i understand i am not able to access the property of the child of the DisplayObject as it is a static property...

so now i am trying to figure out how to access that property in the child Class.

ActionScript 3.0 :: Accessing A Property Of An Instance Inside A Dynamically Created MC

Sep 17, 2009

Im dynamically creating an instance of a movieclip, call it a game piece. This game piece has 4 frames, each with a movieclip called base(although one is red, one blue, one green, one yellow). When the game piece is created I set the frame to indicate player color. Im also changing the alpha of base to 1.0 when its being dragged, 0.5 when its dropped.

Using the following code, everything works fine if the game piece color is set to the base in frame 1 (red). If the game piece is created and the timeline moved to a frame other than 1, I throw an error when trying to access base.alpha (this would be the second, third, and fourth instances of base in the game piece timeline). Heres the strange part, this is only a problem when the game piece is first created and added to the display list. Once created, even after the error has been thrown, I can access the alpha of bases 2, 3, and 4 in the drag start/stop listeners. Heres a link to the work in progress, and the relevant sections of code (shortened for brevity, t1 is the top left piece on the pallet, others just repeat the same code):[URL]

Flash - Accessing A MovieClip's Property Within A Sprite (and Vice-versa)?

Jan 11, 2011

test.fla's document class is Test.as
test.fla's library has two MovieClips ThingMovieClip and Thing2MovieClip

I tried accessing the Thing.as public var thingState's property;

directly,

using something called Casting (??),

assigning an instance name,

but something that seemed so simple doesn't work,I commented the errors I got next to each way I tried,conversely how would I access the MovieClip Thing2MovieClip from Thing.as (which is a child of Test.as because that's where it's instantiated), it just doesn't recognise an object of its parent exists, here are the 2 classes:

package com.hello.test.test
{
import flash.display.Sprite;
import flash.events.Event;[code]........

I think i'm missing some basic but fundemental understanding of ActionScript 3 and I have no other knowledge of other scripting /programming languages either.when I follow tutorials exactly they seem simple enough, but then start applying what I think is logical usage then it throws up errors..

ActionScript 3.0 :: TypeError: Error #1009 When Accessing A Method Or Property From A Subclass?

Jul 10, 2009

error When your accessing a method or property from a subclass. Here's what I have done so far but no luck in my script.

1. I tried waiting for my attached movieclip to be added to my stage using the setTimeout method but no luck.

var timedProcess:Number = setTimeout(initRevealDropDown, 1000);
private function initRevealDropDown():void
{
clearTimeout(timedProcess);
var myInterface:Interface = new Interface();
myInterface.revealDropDown();
}

2. I also tried extending my subclass to interface where my instance method is defined for revealing my dropdown menu, no luck on that one.

ActionScript 3.0 :: Accessing MC On Stage From External SWF?

OK, I load an external SWF on stage.

I have a mc on there already, it's called 'darkOverlay' (instance name).

This is the code I'm trying to use to access it:

Code:
trace(stage.getChildByName("darkOverlay"));
if(stage.getChildByName("darkOverlay"))
{
MovieClip(stage.getChildByName("darkOverlay")).gotoAndPlay(21);

It returns null even when it's loaded in the main swf. What am I overlooking here?

I have a movie clip on the stage. In the main .as file, I can easily access the instance i.e., myMovieClip_mc.x = 10; How do I do that from a class in my "classes" package? I am passing the stage instance into the constructor of the class, so I would think something like myStage.myMovieClip_mc.x = 10 would work, but it comlains that it is null.

ActionScript 3.0 :: Accessing Objects Already On The Stage?

Nov 10, 2009

I'd like to be able to access some objects which are on the stage before compile time (e.g. in my .fla file). I can do this fine from the document class using the names I've assigned to them, but I need to be able to do this from other classes (instantiated at runtime) too.
 
What is the best way to go about this? Can I use the stage variable (this isn't looking likely from what I've read so far) somehow? Or do I need to pass in references to these objects from my document class when I create the instances of the class that needs to access them?

Flash :: Accessing A Symbol That Is Already On Stage Through As3

Jan 4, 2012

I have several symbols in the library (using Flash CS5), and all of these instances have a custom base class set with a method (lets say x()). I have the symbols already positioned on the stage using the IDE, and I wanted to access them through as3 and run the method. I understand that you can instantiate a new object of an item in the library, but how would I access the object that are on the stage already?

var objectList:Array = new Array();
objectList.push(InstanceName1);
objectList.push(InstanceName2);
objectList.push(InstanceName3);
objectList[0].x(); //trying to run the method on the existing Symbol

However, flash returns an error saying that the object does not have method x(). Also looking through the debugger, it doesn't seem like the item pushed is an instance of the base class, rather it says (prototype). This works of course if I were to create a new instance of each, but I would rather access the ones that are on the stage already.

It has no trouble loading things directly to the stage, but it can't find my movieclip for some reason. I have exported the movieclip for actionscript in the symbol properties panel and have given it an instance name.I've tried theStage.myMovieClip.addChild(mySwf); and suchlike, but always get this error message in output:ReferenceError: Error #1069: Property myMovieClip not found on flash.display.Stage and there is no default value.at MethodInfo-206()Some more information: It works from the main class without any trouble.

ActionScript 3.0 :: Accessing Stage Elements From Within Nested MC?

As you might've guessed, what I'm trying to do is set the gunAmmo.text property from within my pistol class. I've tried using MovieClip(root).gunAmmo, stage, etc., but neither seems to be working. I sort of get why, but I don't know what the correct syntax is. (And yes, the TF's instance name has been set correctly.
