How do you access an instance of a symbol created and added to the stage through the addChild(); method, from a different class?

So I have one movie clip on stage rect_mc and document class Main.as I can import movie clip to document class with [code]...
but is there any way to manipulate rect_mc without craating new instance and attaching it to a stage with addChild()
im trying to access Stage Instance in other class but i cant
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MyClass()
at Main()
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?
View 1 RepliesI 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 RepliesHello I need to remove a ENETR.Frame listener to a frame on stage from a symbol.
View 13 RepliesI have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
I created a button (button symbol), inside this button symbol there is a vector shape which will change colours in mouse over and a dynamic text field. i want to use this button symbol in more than one locations in my stage. so i need to change the label of these instances (by changing dynamic text ). but i can't access the dynamic text in as3 using following code,
btnsample.txtbtnlabel.text = "button label"
this code is working fine for a movie clip symbol but not for a button symbol.
on my timeline i create a new instance of the class FirstClass with the following
code:
var firstObject:FirstClass = new FirstClass();
the class looks like this:
package {
public class FirstClass extends MovieClip {
public function FirstClass() {
[Code]....
On my timeline i would like to acces the x position of the object tempObject
I know this is one of the most basic things, but I am having trouble adding an instance of a symbol to the stage with action script in Flash CS4. I have a "fireball" symbol and at the beginning of my code I say:
var myFireball:MovieClip = new fireball;
addChild(myFireball);
But it says : "1180: Call to a possibly undefined method fireball."
In actions script 3.0 I would like to retrieve the class of two instances and then compare them. Is there a way to know what class an instance is made of?
View 1 RepliesI have a symbol called s1 in the library and I also created an instance of it on the stage on the first frame, its name is myS01Before I linked the document to a class (this was for youtube player) I was able to add event listeners, such as mousevents, onto this instance in my actions panel. But, after I linked my document to the external class in a package without a name, I cannot add any code into Actions panel, because it gives me all kinds of weird problems.Instead I am trying to use this symbol and add listeners to it in my external class file (the one linked to the document) with no luck.my external class file looks like:
package { import flash.display.Sprite; import flash.display.Stage; import flash.display.StageAlign; import flash.display.StageScaleMode; import src.com.enefekt.tubeloc.MovieSprite; import src.com.enefekt.tubeloc.event.*;

I bought Flash recently and I'm getting started on making a game, a platform shooter game, thing. What I have, is a button on the main stage that I want to activate a function in an instance. But that instance is inside a symbol. So it's Stage->Character->Gun. But if I put down:
Shoot.addEventListener(MouseEvent.MOUSE_DOWN, Fire);
//Shoot is the button on the stage
function Fire(evt:MouseEvent):void{
Derp(); //This being the function I want to be activated
}
This is the code in the Gun instance:
function Derp():void{
//epic code goes here
}
It will give me an error saying "1180: Call to a possibly undefined method Derp." So basically it's telling me it can't get to this code because it's not on the same stage. How can I get an instance to be recognized by all code in my project, regardless of we're it is in the project? I want to keep all my symbols where they are, so external ActionScript file won't be good if I have to recreate the object on the stage.
I added a graphic to the stage and I need to access it from actionscript
View 1 RepliesI am completely new to actionscript although I do come from a OOP background. I have been asked to trial Flash and Actionscript 3 in particular - so I do come with a few preconceptions on how I expect actionscript to behave. I have a problem I donot understand. I have created a new class and to test it I use a simple test harness in the form of a .fla file.
The issue I have is when I create a new instance of the class and assign it to a variable, subsequent background changes to that instance of the class are not 'picked-up' when referenced through the variable. I would expect that given instance of class could be assigned to many different variables and any updates using one variable would accessible using any of the other variables.

Is it possible to rename a class-instance that has already been created with a specific name?
For instance:
// Step 1) Create and name class-instance
var myClassInstance_1:myClass= new myClass();
// Step 2) Change name of myClassInstance_1

Say i have a movieclip named a_Mc ( ClassA ) I have a sub-movieclip named b_Mc ( ClassB )
CASE 1: Accessing the sub-movieclip b_Mc which is already present inside the a_Mc movieclip
( Since Flash IDE has "Automatic instance naming" OFF )
ClassA mentions the name of b_Mc as => var b_Mc:MovieClip;
NOTE HERE: That the variable name MUST BE same as the name of the instance on stage.
So i can access it as : trace( a_Mc.b_Mc);

I have this main (document class) in a Flash project:
package {
import flash.display.MovieClip;
import flash.events.Event;
[Code]....
Now: if I pass a reference (ref) of the main class to Other and I add clippo as you can see in the first case, I can reference the movieclip clippo from the main (getChildAt(0) is "clippo" from the main). But, is there any way to use the second method (no ref) and do the same from the main class? I can see clippo onstage when Other creates it but I can't understand where clippo "lives" into the DisplayList.
I'm trying to write a custom class for a library object. for example i have a movieClip in my library and there is a textField in it instance name is textField .
i exported my clip for actionScript and i write class definition like "com.xxx.MyClipClass". it's ok, there is no problem. but when i want to access to textField in MyClipClass like this.textField.text ="abc" i got an error undefined property.
I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

i have a MainTimeLine.as Document Class using as3 in flash cs4.it beginning looks like:[code]where the as file is declared in the Document Class of the primary fla file. under this primary fla file, i have a MovieClip symbol which points to another fla file. well this file declares a Class Linkage and i can access the properties and objects of the embedded symbol fine from the MainTimeLine.as script file.however, i have the above public player variable defined, as shown above, in the MainTimeLine.as code.i am having trouble accessing the player properties/methods from the embedded symbol fla file. how do i do that?

I am confronted with a simply yet annoying problem: I manually created a row of MovieClips inside another movieclip container_mc on the stage in the Flash CS4 Editor. The MovieClips are named in the same convention (eg. target_1_mc, target_2_mc, ...target_200_mc).
When I try to access a property of it via AS3 during runtime of the SWF like this, it works:
container_mc.target_0_mc.alpha = 0; But how do I access the MovieClip dynamically? During runtime, a script will determine of which MovieClip i need to access a property. I will get the ID number of the MovieClip I want to access. So I need to be able to to something like this:
var mc_ID:int = 2; ["container_mc.target_"+mc_ID+_mc""].alpha = 0;
Obviously, that doesn't work. When I would create all the target-MovieClips dynamically at runtime, I would simply put them in an array. But in this case I need to work with the existing MovieClips manually created in the Flash Editor.
I created a movieclip symbol and exported to actionscript, I created the .as file:

"graphics" is an image imported on the stage inside my symbol, but it seems not to be accessible this way (I get an error), nevertheless it works this way in as3 then what is the right way in as2 ?
Here's the scenario: We have a creative team that operates in Flash CS5.5 and produces SWF assets which have both graphics elements and actionscript code in them, and an engineering team which authors .as files and builds "code SWFs". The code SWF files must load or embed the creative assets and interact with the code therein for our apps to function.
For iOS mobile development, there is another consideration - it is not possible to load runtime code in an AIR app packages for iOS because of Apple TOS (see related question). Hence, it is not possible to use a Loader to load SWFs in an iOS environment and retain their code.
Embedding a SWF into an ActionScript file the standard way results in a Loader that loads the embedded SWF directly as bytes. This results in access to the top-level, main timeline as follows:
