ActionScript 3.0 :: Accessing Objects From Other Classes?
Jan 7, 2012
I want to access an object from a class in which it was not created in. I have a main class (A) in which I create and instantiate an object (of class B), from this class I can obviously do whatever I want with the object, no problem. The issue I'm having is another class (C) needs to access the object in question to change its x and y location values. Class C doesn't know what the instance of class B, created in class A, is; this doesn't surprise me, but I can't figure out how to allow class C to get access to what class A created.

So I have a menu built inside of Flash CS4 that has a graphic for a background and five text fields that sit on it for menu options. The whole thing is saved as a movie clip in the library. The text fields all have instance names like infoBtn and mapBtn etc. and the menu is already on the stage and linked to it's own class in the library. My problem is accessing those text fields on the menu from the class. I keep getting "Error #1009: Cannot access a property or method of a null object reference." and the menu doesn't work. But if I trace the infoBtn.text in the class it outputs the text that is in the text field. So the code is accessing it but it's still not working?
Code:
package classes
{
import flash.display.*;
import flash.events.*;

I 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.

I've got two classes running...one is a document class (EgoGame.as) and another is a class linked to several similar movie clips (Ball.as).I'm trying to access a public variable from Ball.as which has been declared in the doucment class EgoGame.as.When I run the test the outputs states the following...1120: Access of undefined property _ballPlaced.Here's my code. What I'm trying to do is remove the event listeners from the Ball.as when the _ballPlaced variable is true, so that the user can't drag and drop the balls after they've been placed in a zone.

I have a project that i'm working on, and in the project it's important that i have an object that i can create with actionscript that already has two arrays inside of it. To do this, i made the movieclip, i checked export for actionscript in the library, and in the custom class that corresponds to that object i made the arrays with the following code:
package {
import flash.display.*;

I've been working my way towards better OOP design lately and I've come across a problem with accessing functions in other classes from my Main class. Here is the code:
Main.as
ActionScript Code:
stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);
stage.addEventListener(KeyboardEvent.KEY_DOWN, fireBullet);
They are listening for functions that are within the Player.as class, these functions control the dynamics/movement of the player itelf. But for some reason I'm getting a 1120 error(access of undefined property). Basically how do you listen/access for functions within a different class?

I have 2 swfs, one is main and it loads other file "skin.swf". skin contains object of custom class SkinClass. I can access it from main swf, but when I try to cast that object, the result is null. This happens when I use absolute url, when I load skin from relative url, everything is ok.

I've recently started development on my first proper AS3 project and I�ve hit a sort of brick wall with my knowledge of how to make AS3 classes do what I want. I could do this in AS2 no problem with referencing the stage, but now that only the document class has access I'm stuck.I have instances of a MC called activity. These sit inside a container MC that is the source of a scroll pane (that sits on the stage).
When I click a button inside the Activity MC I need to generate a new MC and set that as the content of another scroll pane on the stage. I�ve tried several things, even gotten the stage passed to the activity MC class but it can't then be used to addChild to items on the stage just reference then (much to my aggravation). And I can�t set an event listener for the new activity�s button when it�s created as it throws a static display object error of some sort.What methods can I use to pass information from a MC class back to the stage so i can call a function or just paste a MC onto the stage? I'm at my wits end after about 10 hours of exhausting everything the internet seems to have to offer on the subject.

How do you access Library items from classes other than the document class?For example, if I create a movie clip in Flash and Export it for Actionscript with the name Foo, I can do this in the document class:
Code: Select allvar f = new Foo();
this.addChild(f);
And it appears on the stage, as it should. But I need to be able to create other instances of this object from other classes. If I use the same code above in SomeOtherClass.as, I get nothing on the stage, obviously because this class doesn't know about the Foo object in the library.

I have a document class which links to several classes, one of which adds a container onto the stage and loads external .swf's into it.Q: How do I access the various classes loaded in the document class from the external swf timeline?For instance, when you click a button in the loaded swf it changes the soundtrack from the soundtrack class. I have tried dispatchevent from the external swf timeline, but I still can't seem to get it to work. Is this supposed to work, or should I be doing something different?

I began with a class for a movie clip rollover function FigureRollOver. It works marvellously. Three things happen:
1) it loads XML from a file "mod1_fig1.xml" and uses another class, XMLMember, to retool the scoping of the XML so that I can get at it
2) an onload call inside of XMLMember calls the myOnLoad function and transfers the XML into an array.
3) so long as the array is finished building, rolling over a movie clip attaches a new movie clip with the rollover text in it.But I don't want all those functions in one because I need it to be more dynamic, starting with being able to load any old xml file instead of just "mod1_fig1.xml", plus it seems lik overbuilding to have all of that in one class, so I've separated out the loading of the XML and building of the array into its own class, FigureXMLLoader. FigureRollOver is then left to just attach the rollover with text in it, extracted from the array built by the new class.
Problem is, though the array builds inside FigureXMLLoader, I can't figure out how to make it available outside the class. I know that I'm constructing things in the wrong order, and that the array needs to be somehow built inside the class function to be available, but I can't figure out how to do that. A cruddy work-around is to put a function call at the end of the building of the array, which calls yet ANOTHER function on the main timeline of my .swf to put the array I've just built into a new variable.This works, but it's messy. It seems like I should be able to have one line of script in the .swf that generates an array on the main timeline (or just a public array) which I can then access from my FigureRollOver class:
var myRollOvers:Array = new FigureXMLLoader("mod1_fig1.xml");
Here is FigureXMLLoader (see comments in the code for more details) which obviously does not return an array as it is, because of all the working around I've had to do. Note the "testing" variable, which can be traced from the main timeline of the .swf, but I will get "not what I want" because of course the array hasn't been built yet, and never will be, inside of the declaration as it is. How do I get it in there so I can return an array?

i've got two classes and i'm not extending to MovieClip. I like to attach the mc in the constructor just because i'll be working with different MC's that have the same purpose.
however, im using private var loadedMC:Movieclip and now i've got another class that needs to be able to access the instance's variable.
for example, myClass.loadedMC , but this would mean having to make it public and I rather not go that route.

I have 2 classes Main.as and RedPawn.as (yes, in the same folder).I am wanting to check if a child exists on a movie clip in Main.as through RedPawn.as.This is within a for loop since I am checking 24 possible values for _dest until I find a match.This simplified code example would be in the RedPawn class:
Code:
_dest = 'example_mc'; // example_mc is pulled from an array
if ( MovieClip(root)._dest.numChildren < 2 ) { // do stuff; }

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?

Here's my code:
Code:
function loadProjects(loaded){
if(loaded){
projects = this.firstChild.childNodes;

the traces within the function return correct results, however when trace values of the arrays within the function and created by the xml are attempted results are returned 'undefined'.
Why can I not access arrays made in this way from outside of the function?

If I've got a bunch of plain old Objects, what's the best way to map them to a bunch of Classes?For example, if I use an HTTPService to pull in some JSON, then deserialize it, I'll have a bunch of objects which look like:
{ type: "person",
id: 42,
name: "David" }
And I want to turn them into instances of a Person class:
class Person {
id:int;
name:String;
}
(also to be considered: how about some standard way of dealing with relationships between objects? For example, if the Person had an additional "spouse" field:
{ type: "person", spouse: 61, ... } // Where 61 is the ID of the spouse
)

So i a building a categorized menu of different foods. I have a class for "categories" (buttons) which essentially will return a string "salads", "drinks", etc. I now have another class "menuItems" for items within categories and this handles sizes such as "small", "med", "large", etc. My problem now is that when i return "salads", i want to invoke an array which contains all the elements of salads, send it to menuItems which will populate the menu. So far i have both the category objects and the menu object setup. I just cant seem to be able to send the data that the category object is returning and pass it to the menu object. Both of which are added to the stage as shown below:
If there was a way that i could say add all these classes to one class so that they can talk to each other that would be great but i dont know how to do this.

I've been heavily mired in 3D recently, and decided to pay a visit back to good ole Flash.
My problem is this. I'm extending the MovieClipLoader class to create a Preloader Class (yes I'm sure it's been done fifty billion times but). I'm trying to refer to a symbol in a common library, the preloader symbol itself.
Inside my class I have this
Code:
function onLoadStart(target){
baseClip.attachMovie("preloaderTemplate_mc", "preloader_mc", 500, {_x:0, _y:20, _xscale:75, _yscale:75});
baseClip.preloader_mc.gotoAndPlay(1);
}
baseClip is a MovieClip object which takes a MovieClip passed to the constructor of the class in the FLA. (say a container movieclip which has a target clip preloaded into it) The class does load the target clip into the baseClip, but doesn't show the preloader, which makes me think I'm not referring to it properly.

Im trying to get used to packages and classes in AS3. Im used to put all code on the first frame of the timeline, but now i have 442 lines of code on the first frame. Yeah 442. And this is for a game engine so i thought i should put it inside some classes to make it easier to read an reusable. But i have noticed that if i create a class called Code and make a instance of that class like this:[AS]var codeObject:Code = new Code();[/AS]i get a bunch of errors because the class cant Acess the stage and the display list.i found a workaround by linking the class to a movieClip and and do this:[AS]MovieClip(parent);[/AS?

If objects are created dynamically in AS3, using code like this:
for (var num:Number = 0; num<10; num++){
var txtFld:TextField = new TextField();
txtFld.text = 'This is the original text';
this.addChild(txtFld);
}
then later, i want to changet the text of one of the TextFields, how can I do that? The only instance listed in the variables is a single instance of "txtFld" and it is the last one that is created. How can I access the others?

You write:myButt._xscale = 25;Now suppose you don't know it's name, but you get the name from another variable:buttname = "myButt";How do you change its size then? in some compiler languages you can expand the string buttname into its value at compile time, with special flagging, such as:
