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 6 RepliesI 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?
In the first frame, a MovieClip is created by ActionScript and placed on the main stage (This "MovieClip" actually uses a base Class called TextFieldHolder which extends MovieClip.) The Movie Clip has several TLFTextFields with instance names placed at various x/y positions in the MovieClip's first frame (the first frame has a stop(); ) Here is the trouble: When I try to change the values of the text fields in the Constructor of the TextFieldHolder class, I get an error that tells me that the TLFTextFields do not exist. I have found that I can access and change these text fields at any other time or place except for in the Constructor.The strange thing about this problem is that it does not occur in all of my projects.I am currently working on several different fla files and each one used TLFTextFields in the manner that I have described above. Almost all of them are displaying the problem, but some of the earlier ones are not.
View 0 RepliesSo I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

have a movieclip on the stage, whose Class is "com.nestor.elements.letterKey". The class funcKey extends "key" which contains a "public var val:String". I have many instances of letterKey(asdfghj.... a full keyboard), so I'd like to use the IDE to arrange and pass variables. SO, within the Flash IDE/Library, I rightclick the symbol to access its component definition, and add a parameter for the var in the baseclass name:value,variable:var,default:whatever,type:Str ing).Now, in the constructor function for the baseclass, if I trace my variable: it is null.
View 1 RepliesI'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;

I have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
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.
when 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 RepliesI'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?
Is 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?
View 2 RepliesThere 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 can't access a variable on a the stage from within a movieclip thats placed on the stage.

I have 54 MC's on stage, generated dynamically. Now I want to get their x and y positions when rolling over but I am having problems getting the path correct e.g.[code]...
View 2 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");

The code below returns the error message "Error 1120: Access of undefined property stage."

I understand the reason for the error is because I'm trying to access the "Stage" when I'm not at my Document Root. The question I have it how do I do this same thing when I'm not at the Document Root?
I'm having an issue accessing items on the stage from some imported code. I found this topic that discusses the same issue... [URL]
I'm not sure I totally understand how to go about this. I don't understand how to make the object global so I can access it from any class. (I have the same problem with an array I'm working with).
I'm using Flash CS5. I have some instances on my stage declared in the main class and I want to attach some events to them, however at the time of the main class constructor, these are declared as null.
What's the best practice for accessing stage instances? Is there an event listener I could add that will tell me when the stage instance properties have been populated?
Simple example:
public class bleepBloop extends MovieClip {
public var productName:TLFTextField;
public function bleepBloop() {
trace( productName ); // Here it is null
}
}
However, when I access productName later, it's defined.
I have:Stage -> SWF Loader Root -> SWF Loader -> MovieClip -> Nested MC.From within "Nested MC": I can only access "SWF loaders root" time line, I can't seem to get access to the stage's functions..[code]Im trying to call on a function which resides on the main time line.Is there any way to access the main timeline?
View 1 RepliesThis may be a stupid questions but I can't find it.I'd like to refer to movieClip onStage by looping though it for example, I have 10 movieclips name slot1 - slot12 then in my code

hole = pirate.slot3; // My problem is here how do i change this slot3 to slot 4,5,6 ...

how can i access Stage. inside a class?
View 9 RepliesI have a MovieClip MainGame that is associated with my external AS File where all the code lies. Everything works really well but.. I place an object inside the MainGame movieclip and give it an instance name . Now when I try to access it from the .as it says "Access of undefined property xy.."
I tried it with textboxes and movieclips, all the same.. I know it worked 20 times exactly like this and I have even compared an older Game where I accessed it just like this.... I really don't know what Flash is playing on me..

I have a swf that has a loader that loads in a external swf. Immediately I can't acess the stage anymore on the loaded swf. How do I go "up" the hierarchy to access it?
basically how do I access the stage from contactForm? if I'm using data classes for both swfs?
this.stage.Stage.homeMc.contactForm
Here is an example: [URL]
I am try to get the gray number at the bottom to be loaded into the swf code:
this.jackpotName1.line2.text = promotion.slide[GRAYNUMBER].JackpotName1.text()
here is my code

import flash.events.*
import flash.display.*

does it have to do anything with ADDED_TO_STAGE event?

I am creating a fullscreen (no scale) site, so I am placing the position of my movieclips by referring the stage.[code]...
that code sets the x property of the movie clip fine when stand alone but when loaded into another swf it has trouble accessing the stage.
How can I access the height and width of the stage from a child swf? I have already tried both parent and root which give no errors, however they are not tracing proper values and are throwing everything in the wrong place
