Actionscript 3 :: Flash CS5 Reference A Display Object From A Class Other Than The Document Class
Jul 28, 2011Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)

Flash :: Reference Var From Frame On Timeline In An Object Class?
Jan 17, 2011I'm using Flash Professional cs5/AS3 I'll try and describe this the best I can. I'm new to ActionScript. So, in my timeline I have a var on a frame that represents "lives" and i have some code in the timeline that takes down the number of lives depending on certain events, which all works great.
so, now i wanted to make a constructor class that I could reuse for a bunch of movie clip objects and I only want these objects to be able to move if the lives variable is greater than certain number. So now, building my constructor class for these objects i just wanted put an if statement that is looking to see if the lives are greater than a certain number, which if it is then should make these objects do what i want...But, when i run the project I get "1120: Access of undefined property lives."
lives is the var I made obviously like I said, and it works fine being referenced everyone else except when I make a new .as file for these objects then try and reference it. I get the same error when I try and establish "lives" in the main project class too. I'm not sure where I should put this var or how I can make it so i can reference it from an object class. I'm not really sure how to word or describe my issue which has made it hard to search for a tutorial.

ActionScript 3.0 :: Class Object Reference Error - No Default Value
Feb 4, 2010I'm building a game which makes use of a few extended classes. I've recently made a few changes in the way the graphics are ordered and am now running into problems, namely:
ReferenceError: Error #1069: Property grab not found on flash.display.Sprite and there is no default value.
at DraggableSprite/grabObject()
ReferenceError: Error #1069: Property drop not found on flash.display.Sprite and there is no default value.
at DraggableSprite/dropObject()
The general structure is as follows ('>' means extends) :
MovieClip > DraggableSprite > PlantPart > Seed or Flower.
DraggableSprite manages dragging/dropping objects with the mouse. It contains the offending lines of code being:
Code:
private function grabObject(evt:MouseEvent) {
trace("grabTarget: "+evt.target.name);
if (this._draggable) {
_origX = evt.target.x;
_origY = evt.target.y;
[Cde] .....
The Seed and Flower classes contain a public 'grab' and 'drop' function which manage some different effects of being picked up and dropped, but the code seems to stop short at the PlantPart class and register a sprite it contains as the 'evt.target'. I added this intermediate sprite to overcome a colission problem with the mouse. The sprite functions as a dragbox, while the Seed and Flower graphics offer visual feedback.
Actionscript :: Targeting Sprites From A Method In The Document Class - Null Object Reference?
Feb 9, 2011I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.
Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.
I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.
Actionscript 3 :: Loading Swf As Custom Class That Extends MovieClip - Getting Null Object Reference
Aug 16, 2011I followed the example from a previous question and I am loading an external swf using a loader and inside the loader event handler I am trying to cast the loader.content as my custom class PanelReferenceClip which extends MovieClip
When I publish I receive a this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Just to make sure and test that the swf location was correct and the swf was actually being loaded, I changed the type of the content to as MovieClip and it worked fine.
EDIT: I also wanted to add that these swfs are being stored locally and not being pulled across the internet, multiple networks or servers.
I am not sure if I did something quirky in my class so I am providing the source to my custom class PanelReferenceClip
package com.components
{
import com.UI.DevicePanel;
import flash.display.MovieClip;

Flex :: Difference Between Class Reference And Class Instance?
Jun 28, 2010Given that both of these calls to getQualifiedClassName return the same thing (mx:Label), how would one go about programatically differentiating between an instance of a class and a reference to the class...
var lab1:Label=new Label();
var lab2:Class=Label;
var qcn1:String=getQualifiedClassName(lab1);
var qcn2:String=getQualifiedClassName(lab2);
In other words, how could I know that lab1 is of type Label, while lab2 is type "Class". typeof() simply returns "object" for both... getQualifiedClassName returns "mx.controls::Label" for both...
Flash :: Use A New MovieClip As A Class Or To Copy It Without Reference To Its Class?
Jul 21, 2011I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG();
var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.

ActionScript 3.0 :: Inheritance / Interface - Override A Function That Return An Object Of Class A And Make It Return An Object Of Class B Which Extends A?
Aug 4, 2009I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

ActionScript 3.0 :: Reference Main Document Class From Document Class Of Loaded Swf
May 7, 2011I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.

Nov 4, 2010I need to get a pointer to a piece of XML. I can get a pointer to the parent node and everything works but trying to get a pointer to a node that has no children just returns the value of that node.[code]...
Tracing subNode would be just the value and there is no pointer to the original xml object, so editing the subNode var would only change its value, not the one in the original XML object.
How do I get a pointer to the subNode so it can be edited to change the original xml object?
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'";
