AS2 Class Object Referencing
Okay, so I have an object which is derived from mty DrawGrid3d class which works lovely. The draw3d class extends the movie clip class and has a constructor methos which believe it or not builds a 3d grid. Now I cant seem to be able to refer to the objects properties in any way. for example the code below traces out 'undefined'. Any ideas? Cheers
Code: my_grid3d=new DrawGrid3D(_root,130,100,16,16,12,18,176,5.9,0xC5D7FE,0xFFFFFF)
trace("GRID IS:"+my_grid3d._x)

Referencing Other Object Classes In A Class Definition
Here's want I want to do.
I have a ball class and paddle class. I want to put a hitTestObject statement in the ball class that references the paddle class. I need the ball class to perform the same function whenever it hits an instance of the paddle class.
Can I achieve this affect with just these two classes, or do I need to write a third class to handle collisions between the two classes?
Why doesn't this work?
ball class:
ActionScript Code:
package
{
import paddle
import flash.display.MovieClip
import flash.events.Event
public class ball extends MovieClip
{
public var xmov:Number = 5
public var ymov:Number = 5
public function ball():void
{
stage.addEventListener(Event.ENTER_FRAME, enterframe)
}
public function enterframe(event:Event):void
{
if(this.hitTestObject(paddle))
{
ymov *= -1
}
}
}
}
[Flash 8] Referencing Class Variables From OnEnterFrame Created Within Class
Hi,
It's been a while since my last post here, but I was hoping someone could help me with a problem I'm having. I want to reference and change a class variable from within an onEnterframe function defined within a class. I can actually do this right now, but I want to do it in a different way. Here's a code sample of what I am talking about:
Test.fla file:
Code:
var t:tester = new tester()
Working tester.as file:
Code:
class tester{
private var num:Number = 100;
function tester(){
var classObj:tester = this;
var mc:MovieClip = _root.createEmptyMovieClip("test",1);
mc.onEnterFrame = function(){
trace(classObj.num); //This traces 100 (CORRECT!!!)
}
}
}
This traces 100 to the output window, just like it should
Here is the way that I would like to do it, because I want to reuse my onEnterFrame Stuff:
Code:
class tester{
private var num:Number = 100;
function tester(){
var classObj:tester = this;
var mc:MovieClip = _root.createEmptyMovieClip("test",1);
mc.onEnterFrame = this.mcOnEnterFrame;
}
private function mcOnEnterFrame(){
trace(num) //this traces undefined (BAD!!!)
}
}
As you can see, the work around to reading the class variable in the onEnterFrame function is to create a reference to the class object, before defining that function, then using the reference you created to access the class variables.
I have tried various iterations to get the second example working, but have had no luck. Does anyone know a way to get the second method working, or am I stuck using the first method.
[F8] Referencing A Static Class Inside Another Class's Instance
I've got a movie loading into a framework.
This framework has 1 instance of the class main called main.
Inside this class, another class is used, but it is used directly, not as an instance. E.g.:
code:
import com.StaticClass;
class main {
private function UseStaticClass():void {
StaticClass.init();
}
}
From my movie, I can reference the main instance as _root.main. Can I reference StaticClass at all if there's no explicit instance created or it's not assigned to a public variable?
I can't modify main to include getter/setter methods, that's why I ask.
Thanks.
Static Class Variable Referencing Class Instance
I was given the task of writing a class that would send serial requests for xml data, the idea being that the requests could be added while previous requests were still in progress, but the class would queue them and wait for the reply of one request to come back before sending the next.
The way I did this was to create a class instance for each request, and the request itself would be stored in an instance variable, waiting to be sent. A static variable called queue (accessible to all instances) was then given a reference to the instance, and when this reference got to the top of the queue, queue would call the sendRequest() method on that instance.
The reason why I am using one instance per request is so that the replies can be retrieved via the instance, so keeping each request entirely discreet.
Everything works very nicely, but the problem is my IT manager looked at the code and told me that you cannot put a reference to a class instance in a class static variable... and for this reason he has informed my line manager that he has serious reservations about the code, and recommends that it is not incorporated it into the project. However, the code works very well on my local machine and on the testsite, and no-one has experienced any problems with it.
Can someone reassure me here... I can see absolutely nothing wrong with having a class static array hold references to each of the instantiated class instances. And the proof is in the pudding.. it works. Can anyone else see a problem here?
Referencing An Mc Created In One Class From Another Class
Hello everybuddy,
Cracking site, I normally don't post but have read and learned much from here thanks to all the posters!
I'm struggling with AS3 at the moment, forcing myself to take an OO approach and slowly getting there... However I'm now stuck...
My project is a dynamically generated web page, getting pics and data from xml files.
I have a button class that creates buttons based on an xml file, this is in its own class file(buttons.as) which is called from my document class.
The document class also creates a bunch of thumbnails using (screen.as), the thumbnails are placed in an MC called thumbs (which created by the document class).
What I need now is a way of linking my button class to the thumbs MC, so that when I click a button my thumbs MC is tweened using my dotween function.
when I run my project i get an errror from my buttons.as --> 1120: Access of undefined property thumbs.
I guess what i'm asking is how to reference an MC created in one class, from another seperate class. I thought that by setting it to public this would be possible but its not working...
Here is my code:
Code:
//Document.as
package {
import flash.display.MovieClip;
public class Document extends MovieClip {
public var thumbs = new MovieClip;
public var butArr = new Array;
public var screen1:screen;
public var thumbArr = new Array;
public function Document() {
//add buttons
for (var i:uint = 0; i < 10; i++) {
button[i] = new buttons(i);
addChild(button[i]);
}
//add thumb container
this.addChild(thumbs);
//addthumbs
for (var i:uint = 0; i < 10; i++) {
var thumbleft:uint=140+i*320;
thumbArr[i] = new screen(thumbleft,275,i,320,240,"thumb");
thumbs.addChild(thumbArr[i]);
}
screen1 = new screen(140,35,1,640,240,"home");
addChild(screen1);
}
}
}

// Adding some bigger text size
myFormat.size=16;
myFormat.font="SkandiaDisplay";

Referencing An Object
I'm trying to identify which Object should be called by passing an arguement to a function
ActionScript Code:
function myAdd(imageUrl,xPos,yPos,myTransition:String) {
var myImage:LoadObject=new LoadObject(imageUrl);
var ExpandAPrimary:Object={scaleX:1,scaleY:1,time:.5,transition:"easeOutElastic"};
var mytest:Object = ExpandAPrimary;
trace("your test var is: "+ mytest);
myImage.scaleX=0;
myImage.scaleY=0;
myImage.x=xPos;
myImage.y=yPos;
Tweener.addTween(myImage, {base:mytest});
addChild(myImage);
}
When i try and replace
ActionScript Code:
var mytest:Object = ExpandAPrimary;
with the arguement myTransition:String
i get:
ReferenceError: Error #1069: Property base not found on String and there is no default value.
the initial call is
ActionScript Code:
var myclock1:ObjectTimer = new ObjectTimer(.5, 'nut1.png', 0, 50, 'ExpandAPrimary');
Referencing From Object
Hi!
Can anyone explain, how can I reference to a timeline from the object not using _root?! Is it posible?
For example:
ActionScript Code:
var someListener:Object = new Object();
someListener.onMouseMove = function() {
trace("_root "+_root); //_root _level0
trace("this "+this); //this [object Object]
};
Mouse.addListener(someListener);
Referencing An Object
I'm not sure if this is good scripting practice...anyhow... I have a constructor function that creates an object and then attaches a movie onto the stage that is referenced within the original object. Now, if I attach a onPress function to the movie, is there any way to reference the very very first object? I think I am seeing a hierarchy that really doesnt exist...
An example would be:
Code:
MainObject = function(){
this.ref = _root.attachMovie("mc","my_mc",1)
this.message = "hi!"
this.ref.onPress = function(){
trace(?***?.message)}
}
Is there anything I can put in ?***? that would reference the original object and display the original objects message? Sorry if this is a dumb quesion!
Probelms Referencing A Class
Basically I have a class which extends EventDispatcher (DropDownMenu) and creates instances of another class(MenuButton) dynamically the first class is a menu the second the menu buttons for that menu.
It was all working fine until I make and instance of the dropdown menu which then makes instances of buttons and although the classpath is correct it will not make an instance of the button
this["menuMC"+i] = new MenuButton(dropMenu_mc, p_obj.eventName, 1, 1, p_obj.txt, "VP-100-256-639", "icon_mc", p_obj.iconType, 10, yPos);
unless I first declare this["menuMC"+0] = new MenuButton(); explictily in DropDownMenu constructor which defeats the dynamicnesss of it as I dont want to predeclare the vars because I dont know how many buttons there are going to be.
Has anyone experienced anything like this - its like the class has no scope in the parent class unless it is first declared in constructor - any help would be appreciated.
Referencing Stage From Class
Hello,
I am trying to make my first as3 class based game and so i was wondering if i could get some help. although the game wont have fancy graphics, i just would like to understand the way it works...currently, i am at a point where im getting :
1067: Implicit coercion of a value of type flash.display:Stage to an unrelated type Stage.
in my main file robot.fla, im using
var robo:robot=new robot(stage);
//var starenemy:enemy1=new enemy1(this.stage);
addChild(robo);
inside that robot.as
....
public class robot extends Sprite {
import flash.display.Stage;
private var _stage:Stage;
....
public function robot(stageRef:Stage):void {
_stage = stageRef;
...
}
amongst other things and i cant reference anything from the stage.
I think im going nuts trying to figure out how to correctly reference things to the stage. so can you take a look and guide me and tell me how i can proceed?

Referencing Class Methods.
Hi,
I am have a class which I am instantiating in the first frame of a movie.
The class has a method called statecheck which I would like to access from a movie clip symbol.
I can reference the method easily from the first frame. what is the correct way of referencing it from the movieclip?
import Tpanel
var public panel:Tpanel = new Tpanel;
panel.statecheck(this); // works
the same line of code in the movieclip symbol does not.
also
_root.panel.statecheck(this); // does not work in as3
Cheers

Help Referencing A Visual MC From Another Class
I have a fla file with visual content onstage. This Fla also has a document class assigned called Home(extends Movieclip.) One of the visual assets onstage is a movieclip called mcHome that the Home class controls successfully.
I’ve got another class, Photos(extends Sprite) that I have imported(from another package) and it also successfully does what it’s suppose to. However, when I add code to Photos to refer to mcHome, the onstage movieclip, I get an
1120 access of undefined property mcHome error
What is necessary to make Photos understand what mcHome is?
Thanks
Referencing An Object In An Array
This is practically spam and I appologize. I think I can better articulate my problem now- and thought a new post would help.
If _inventory[2] = "a string" that is my Event.target I could:
trace(Event.target)
And it would trace "string".
trace(Event.target == "a string")
And it would trace true.
Same is true for:
trace(Event.target == _inventory[2])
Now, if I replace _inventory[2] with an instance of the class string_mc and it is my Event.target I can still:
trace(Event.target)
But now I get:
[object string_mc]
And I can still:
trace(Event.target == _inventory[2])
And get a true.
But if I try the equivelent of trace(Event.target == "string") I cannot make it work.
trace(Event.target == [object string_mc]) gets a syntax error.
trace(Event.target == object string_mc) doesn't work.
trace(Event.target == string_mc) comes back false.
Using === instead of == doesn't work either.
So, what do I put between the == and the closing paren to make this work?
Object Referencing Question
if i've got an MC on the main stage named "mainContact", and this mc has the code:
ActionScript Code:
onClipEvent( load )
{
phpVars = new loadVars();
phpVars.load( "pages/contact.php" );
phpVars.onLoad = function( success )
{
if( success )
{
doneLoad = "true";
}
}
}
i'm wanting to check from within "mainContact" if doneLoad == true, but since it's in the phpVars.onLoad function, doneLoad is registered under phpVars. how can i make doneLoad be referenced under mainContact without using absolute referecing as in, "mainContact.doneLoad = true;"?
Variable Object Referencing
Hello, I just stumbled across your forums today looking for an answer to my question on Google.
I am in no way very knowledgable with ActionScript, so this might be very simple and I am looking in all of the wrong places... but basically here is my issue:
Instead of accessing an objects attributes like this, _level0.thumbnails.thumbnail0._width = 500;
I want to be able to access it with _level0.thumbnails. (this.id) ._width = 500;
where as (this.id) is a variable that could be equal to "thumbnail0" or "thumbnail99" depending on which object gets clicked. I have everything working to if I hardcode thumbnail0 it works fine, and this.id does get set to whatever thumbnail I click's "thumbnail" + ID
... any help?
Array Referencing Object
I have created an object that I wish to put into an array. I will have several objects with different commands that are going to be in this array. I would like to specifically reference the different variables in the objects. I thought I had everything going but when I traced the array the different variables are listed as undefined. How do I specifically reference a variable of an object that is placed in an array?
var MyObj = new Object();
MyObj.Title = "CTRLA.jpg";
MyObj.Command1 = "yeah";
MyOBJ.Command2 = "Nah";
objective = new Array();
objective[0] = MyObj;
trace (objective);
for(i =0; i < objective.length; i++){
trace(objective[0].Command1);
}
Thanks,

Dynamic Object Referencing
Hi everyone,
i've built a accordeon like movie clip to present search form results for a web site. The results are "fed" into flash by .NET webservices and the "accordeon" itself is dynamic.
My question is i want to add a button to show further detail on each line of results, but i don't seem to be getting the button to be clickable inside the individual lines.
this is the code i use to build the "accordeon" display:
ActionScript Code:
// _y position
var y = 0;
// _depth
var d = 0;
for (i = 0; i < 13; i++) {
linesArray[i] = i;
d = d + 1;
y = y + 20;
// check for empty (undefined) results and stop adding lines
if (theResults.Collection[i].Referencia == undefined) {
i = numRegistos;
return;
} else {
attachMovie("acordeonLine", "line" + i, d);
// fill the line text boxes
txtRef = myresults.ref;
txtName = myresults.name;
}
// use the line it self as a button to slide open and show photos
this["line"+i].onRelease = function{
trace("HEY! YOU CLICKED ME!");
}
}
inside the each "accordeonLine" mc there's a button called btDetails i'm trying to use by adding this (or similar) code inside the for loop that adds line to the accordeon:
ActionScript Code:
this["line"+i].btDetails.onRelease = function{
trace("HEY! YOU CLICKED ME!");
}
the path this["line"+i].btDetails evaluates as undefined. its like its not even there.
i've tried other "tricks" but i simply can't get the click to work.
Any ideas?
Referencing A Subclip From Within A Class File
Say I have the following movieClip Structure
myMovieClip
myMovieClip.subMovieClip
I want to make a Class file for myMovieClip
I would like this Class to reference and adjust the subMovieClip._y using commands from the class file.
I keep getting errors when trying to do this. Is this a matter of syntax or is there no way to reference another movieClip from a class file?

Referencing Class Variable From Inside Self
I have a class in an external .as called CustomGroup, and it will take in and process a number of objects which I want to name.
Code:
var myGroup:CustomGroup = new CustomGroup();
var otherGroup:CustomGroup = new CustomGroup();
myGroup.storeMarkers(someArray);
otherGroup.storeMarkers(otherArray);
I would like for each marker in someArray to be indexed with the instance name of the class object (i.e. "myGroup001", "myGroup002", "myGroup003") and ("otherGroup001", "otherGroup002", "otherGroup003")... but I cannot figure out how to target the class variable name from inside itself.
Help?
Dynamic Class Referencing Question
Quick question, I'm sure this is a stupid syntax problem...

fighterPattern = new classes.ai_routines.SwoopDown(this, 20, 1, 5, 5);
The second one creates the object as it is supposed to, but the first one does not. What is the correct way to dynamically reference the object?
Thanks in Advance
Problems Referencing Parent Class
I would like to have a child access the properties of the parent class and I've read _parent allows you to reference a parent object. However, I can't seem to get it to work. Here's an example.
Code:
class test{
public var name:String;
public var Test:test2;
function test(){
name = "testSring";
Test = new test2();
}
}
class test2{
function test2(){
var This:Object = this;
trace(This._parent.name);
}
}
//in the .fla
var Test:test = new test();
If I run it, I will get "undefined".
Referencing Stage.stageWidth From A Class
I created a custom class in a .as file. I then linked this custom class with a symbol from the library in my .fla file. However, I can't reference stage.stageWidth in my custom class file. I get a null object error.
I think this happens because the custom class file is associated with a symbol on the stage and not the stage itself. For example, if I set the fla file's Document Class to the name of my custom class I can reference stage.stageWidth in the custom class. But I don't do this because I am creating multiple instances of the symbol on the stage. In order to do that properly i found I have to set the class in the properties panel of the symbol to the underlying class which then defines how each symbol behaves.
Under this type of linkage, is there a way to reference the stage width from the class?
I've tried root.stage.stageWidth and parent.stage.stageWidth to no avail. I also made sure to import flash.display.* in my custom class.
Below is the code for my .fla file and my .as file. In the .as file you'll see the line "x = Math.random() * stage.stageWidth;". This is the line giving me problems. I could hard code it, as I do for the y variable on the next line, but I'd prefer not to in order to keep the code flexible.
I also attached the files in a zip.
Any help would be appreciated.

Referencing A Instance Inside A Class
Hi --
I am working on converting a movie clip to a Class so that I can more easily
reuse it in later projects.
I have pretty succesfully converted my AS code from my include file to a
Class file. However, I have two objects on the stage, topBG and botBG and
whenever I reference these items inside my code, such as botBG._y I get an
error at compile time saying "There is no property with the name 'botBG'"
How can I set it so these assets can be referred to inside my code?
The code worked fine when it was just a movie.. Also, this is ActionScript
2.0.
Thanks

I have an external class file that extends the MovieClip class and is linked to a movieClip on the main stage. I need it to be able to access properties of other movieclips on the main stage. How could I do this. Here is what my base movieclip class that I want to access the stage with looks like. Remember, it is linked to a movieclip on the stage, if that matters...
Obviously there is more code in the class, but I removed it for the sake of simplicity.
Attach Code
package{
import flash.display.MovieClip;
import flash.display.DisplayObject;
import Math;
public class Test extends MovieClip{
public function Test(){ //Constructor
}
}
}
Referencing Stage.stageWidth From A Class
I created a custom class in a .as file. I then linked this custom class with an symbol from the library in my .fla file. However, I can't reference stage.stageWidth in my custom class file. I get a null object error.
I think this happens because the custom class file is associated with a symbol on the stage and not the stage itself. For example, if I set the fla file's Document Class to the name of my custom class I can reference stage.stageWidth in the custom class. But I don't do this because I am creating multiple instances of the symbol on the stage. In order to do that properly i found I have to set the class in the properties panel of the symbol to the underlying class which then defines how each symbol behaves.
Under this type of linkage, is there a way to reference the stage width from the class?
I've tried root.stage.stageWidth and parent.stage.stageWidth to no avail. I also made sure to import flash.display.* in my custom class.
Any help would be appreciated.
Referencing Timeline Variables From A Class
Yet another question..How do I referece, within a class function, variables residing in the timeline that is invoking the class? (Very beginner here!)
So far I've had to send the timeline variables from the timeline to the class's function as parameters, which works, but there's so many. And I know I can just make these variables reside in _root and reference them this way, but that is not smart.
Does it have to do with _parent at all? Tried using it but failed..
Thanks.
Sub MC Referencing From Dynamically Named Object
Hello All!
Here's what I'm trying to do. I have a base movie clip with 2 inner movie clips inside it. I am dynamically setting the color of one of the inner movies. Here is my code
code:
sqColor = new Color(_root["square" + j].filler);
sqColor.setRGB(thisColor);
This code sets the color of a movie labeled filler within my "square"+j MC.
Accessing the dynamic variable name through the _root array works fine. HOWEVER! I cannot use the _root array. I am using the loadMovie function in another MC to call this MC. So the _root array is no longer the same and it doesn't work.
Is there another way to do this? I've tried to access the "square"+j object with out the _root reference, but no luck.
Any suggestions? THANKS IN ADVANCE!!
AttachMovieClip - Referencing A Dyamic Object
I have begun using the attachMovieClip() recently to dynamically assign objects to movieclips. Up until now it has been excellent, and is perfect for assigning various enemy sprites to instances of a movieclip etc.
At the moment though i am having problems getting messages through to the 'attached' clip to tell it to stop() or play() etc. The info is a little unclear on this topic, but it seems that if i use code like:
dummy.attachMovie(cat, cat add i, 1);
and then say dummy.stop(), that it only targets the original 'dummy' clip and not the 'cat' movie i have attached. I have tried referencing it with the assigned name, but i must be missing something or doing it wrong, any ideas??
thanks!!
Referencing Object Using Variable Syntax
I'm having trouble referencing an object using a variable in Flash MX.
In this example, I'm dynamically loading jpegs and need to test that they have finished loading.
The img var contains the url of the image to load.
On the first frame:
for(i=0; i<number_of_images; i++)
{
//duplicate the holder
duplicateMovieClip(my_movie.holder, i, i);
//create reference for the img to load
img_to_load = "my_movie.holder." + i;
//load image into the duplicated movie
img_to_load.loadMovie(img_url);
}
On another frame:
if(img_to_load.getBytesTotal() >= img_to_load.getBytesLoaded() )
{
//image has loaded
}else{
//image still loading
}
My problem is that img_to_load is a variable that returns a string and not an object - what do I need to do?
Thanks in advance
[Help] Classes Object Ownership And Referencing
I want to access methods and data of an object A from another object B - which was created in the object A. However, using the _parent property doesn't work. I need an explanation why doesn't it work.
To futher clarify my question, I have a problem when using classes in this way:
code:
class MyClass
{
var Some_Data:MyOtherClass;
function MyClass
{
Some_Data=new MyOtherClass();
}
function DoSomething():Void
{
trace("Did something.");
}
}
class MyOtherClass
{
function MyOtherClass
{
SomeProcedure();
}
function SomeProcedure:Void
{
_parent.DoSomething();
}
}
When I create an instance of the MyClass there is no output. I need an explanation why this is so.
Edited: Have corrected some mistakes in this thread
Referencing An Object's Variables In An Array?
I have created an object that I wish to put into an array. I will have several objects with different commands that are going to be in this array. I would like to specifically reference the different variables in the objects. I thought I had everything going but when I traced the array the different variables are listed as undefined. How do I specifically reference a variable of an object that is placed in an array?
var MyObj = new Object();
MyObj.Title = "CTRLA.jpg";
MyObj.Command1 = "yeah";
MyOBJ.Command2 = "Nah";
objective = new Array();
objective[0] = MyObj;
trace (objective);
for(i =0; i < objective.length; i++){
trace(objective[0].Command1);
}
Thanks,

Timeline Control & Object Referencing
Hi,
I'm wondering what the proper ActionScript is to control a timeline within an event handler function. In an xml.onLoad function I want to send the main playhead to a certain frame based on the content of the XML. The only way I have found to do this is using _root.gotoAndPlay within the {} of the onLoad function; using gotoAndPlay, this.gotoAndPlay, this._parent.gotoAndPlay etc. doesn't work. These would of course work if they weren't within the onLoad function -- thus something about being within an object function changes positioning/referencing of movie clips and timeline control.
_root is a workaround and it's not perfect. any ideas on how to properly control timelines from within functions such as xml.onLoad?
Thanks in advance!
[CS3/AS2.0] Need Some Help... (AS Tween/object Referencing Issue)
Hey guys,
Im trying to create a tween that will animate in any page that i give it. At the moment i have this.
PHP Code:
function pageTransitionIn(i:Number):Void {
new Tween(["big"+i+"_mc"][mask_mc],"_x",Regular.easeInOut,["big"+i+"_mc"][mask_mc]._x,-10,1,true);
}
function pageTransitionOut():Void {
new Tween(["big"+i+"_mc"][mask_mc],"_x",Regular.easeInOut,-10, 700,1,true);
}
pageTransitionIn(1);
My problem is that this code doesn't work, however when i try a specific big1_mc it does:
PHP Code:
function pageTransitionIn():Void {
new Tween(big1_mc.mask_mc,"_x",Regular.easeInOut,big1_mc.mask_mc._x,-10,1,true);
}
function pageTransitionOut():Void {
new Tween(big1_mc.mask_mc,"_x",Regular.easeInOut,-10, 700,1,true);
}
So im obviously just referring to the object wrong. Does anybody know the correct way to refer to big1_mc.mask_mc with i in place of the number so that i can use it for multiple pages? I've tried this and _root but i can't get it working.
Thanks
[F8]Path Independant Object Referencing
Is it possible to reference objects in flash independent of their path. I am using flash as an interface for an external system. The external system used channel messages (1-10000) that I wish to tie to buttons. The buttons may exist on any form within a movie so connecting each incoming channel message the appropriate button in code will be very time consuming. If I could just address the appropriate button via it alias irrespective of its path then I could simply alias my buttons B1 - B10000 and use a simple function to connect the channel message to the button. Any suggestions?
Thanks in Advance
Referencing An Object Created By A Function
Why can't I reference an object created by a function if it has been added to the stage?
For example, I write a function that creates a text field and adds it to the stage:
ActionScript Code:
function makeText():void
{
var myText:TextField = new TextField();
addChild(myText);
}
Now in another function I want to say myText.text = "Hello!", but I get the error "1120: Access of undefined property myText.".
I know it has to do with scope, but how do you access something that's been added to the stage outside of the function that created it?
Button Transparency And Referencing FLA Object From AS3.
I'm using the following graphic and animating the mouth when clicked. Problem is I don't want the CLICK event to dispatch when the transparency is clicked. I know using the flash file I can draw a graphic the shape of my image and place it behind the image and dispatch the click event for the drawn shape, but here's my question.
Is there a better way of doing this for buttons with transparencies?
If not how do reference a drawn graphic in my fla file from my as3 file?
Thanks
Flash Mx Object Referencing Problem
hi there:
I have
loadMovie("bridge1.jpg",_root.pict_dropzone);
in a.swf
this works fine. when a.swf tested alone.
but when b.swf uses code to load a.swf onto b's screen at runtime the line of code above doesn't work
I guess _root.pict_dropzone is the problem and has to be changed to this._root.pictdropzone
where this refers to a.swf
what's the correct syntax for this?
_root Replacement For AS3 For Object Referencing
Hello,
I am having some problems with accessing objects on the main timeline.
I am calling this function registerMenuButtons() from a function getDimensions() in AS3:
function getDimensions():void {
registerMenuButtons();
}
and registerMenuButtons accesses a textfield in a movieclip on the main timeline:
function registerMenuButtons():void {
graphics_gr.start_txt.text = "start"
}
however it seems to be a null object reference, text does not change.
In AS 2 I would have used _root to reference graphics_gr.start_txt.text. However I understand that it does not exist anymore. So I defined a variable called ref = this.root, and when I trace ref.graphics_gr it gives me "[object] point1. However this does not apply for start_txt, and instead when i try ref.graphics_gr.start_txt it gives me a null reference.
Is there any way to use a similar method like _root in AS2 to access an MC? Really don't know what's the problem, and I am not using any custom Document Class at the moment. Thanks!
Two Object Referencing Same Member Array?
I'm working a neural network project and my basic architecture is this:
1. Neurons
2. Neuron Layer (basically an array of neurons)
3. Neural Network (basically an array of Neuron Layers)
When I reference the first Neuron Layer's array.length it gives me the total number of neurons in the network rather than what the number of neurons in the first layer should be. The same thing happens for the second layer and each subsequent layer should there happen to be more. I've added trace statements to the Neuron Layer constructor that tells me a neuron has been added and I've also added a trace statement after the first neuron layer is added and the second neuron layer and I get the correct number of "neuron added" statements before the "first layer added" statement and the correct number for the second layer as well. This pretty much assures me that the actual number of neurons in each layer is correct when the first layer is created but somehow the number of neurons in the first layer and subsequent layers is actually becoming the number of neurons total. The only thing I can figure out is that somehow, the first neuron layer object is referencing the same neuron array member as the second neuron layer object. Is this possibly what is happening?
Dynamic Referencing With Color Object
Hello, need help. I am building a game where the first five numbers of 20 randomly selected numbers are colored differently from the rest. The code I'm using looks like this:
function coloron() {
for (i=0; i<=80; i++) {
if (x == i) {
newnumcolor = new Color(_root.ball_movies_all["BallMovie"+i]);
newnumcolor.setRGB(0x660099);
backcoloron();
}
}
}
I am using dynamic referencing to setRGB of the nested movie clip. It sounds good in theory, however, this does not work. If I target the clip above the one I want, "ball_movies_all" the setRGB works perfectly fine. But when I target the dynamically referenced clip, the setRGB does not work. Any ideas/workarounds would be greatly appreciated.

Referencing A MovieClip Object From Within A Function
I have a movie clip that loads a file. If the file contains a certain value I want to call a function and send it "this" (a reference to this movieClip object). But "this" does not refer to the object, instead it seems to be linked to the values the file has loaded.
-----------------------------------------------------------------
function successFunc(success) {
if(success) {
if (myLoad.featured == "yes"){
_root.registerMeFeatured( this );
}
}
}
------------------------------------------------------------------
The above is what I have and it sends the contents of the file rather than a reference to the movie clip (which is what i would like).
-----------------------------------------------------------------
_root.registerMeFeatured( this );
------------------------------------------------------------------
The above, when used outside of the function will work properly and send the object as I would like. How can I make this work within the function? Thanks in advance.
Referencing A Movie Clip From A Class .as File
Okay, so I'm making a game. I've made various class files for various elements on the screen and used linkage to make the movie clips on screen members of my custom classes (by right clicking on the movie clip in the library and selecting linkage, etc). But I'm having an issue...
I can't reference child movie clips. So say I have a movie clip called "sea", and within it I have one called "fish" (instance name, of course). I use linkage to make "sea" a member of my custom "SeaClass" class. However if I try to do something like this.fish.gotoAndStop(5); I get an error saying that there is no property "fish". I understand that it's looking for a "fish" function instead of the "fish" subclip, but is there any way to make it reference the subclip?
This is a big issue because I'm having to use a lot of onClipEvent(enterFrame) variable checks for my subclips and whatnot to make them execute something instead of being able to put the command straight in a function and its really bogging down code.
I hope this makes sense... thanks in advance for the help!
Referencing The Root Timeline Within Using _root In A Class
I have a class that I wrote and I need to reference the root timline but I can't use _root to do that because my movie will be loaded into another movie. Is there another way to reference root?... maybe a _global variable? If so, how would I set up that global variable on the root timline and then use it in the class?
Thanks.
Referencing A Parent Method From A SimpleButton Class
I'm new to AS3 (know AS2 fairly well), and am having trouble wrapping my head around OOP methods of doing things. I know it will keep things organized and more modular, so I'm trying to learn, but am having trouble...
Specifically, I've defined a method called showScreen within the document class (Main). I've also defined a NavButton class that's attached to a hand full of simple buttons objects. The only problem is that, when one of the buttons is clicked, I receive an error that the parent class's method (showScreen) isn't defined.
1061: Call to a possibly undefined method showScreen through a reference with static type flash.display:DisplayObjectContainer.
(It's worth noting that I'm still learning to read those fancy new errors, and that making things public / private / static have only confused me further as to their relevance to my problem.)
PHP Code:
// Main.as... abridged to save you time
package com.as3Adventures
{
public class Main extends MovieClip
{
function Main()
{
// sets up the elements on the stage, etc
}
public function showScreen(which:String):void
{
// animates the old screen out and displays
// another, based on the variable passed
// this is the method I want to call
}
}
}
And
PHP Code:
// NavButton.as... also abridged
package com.as3Adventures
{
public class NavButton extends SimpleButton
{
function NavButton()
{
// sets up the button...
addEventListener (MouseEvent.CLICK, clickHandler);
}
function clickHandler (e:MouseEvent):void
{
// does a little magic with the button, animating, etc... then...
trace(parent); // returns "[object Main]"
parent.showScreen(this.name); // <------------ Causes headaches
}
}
}
I suspect that making NavButton extend MovieClip rather than SimpleButton would fix this (am I wrong? I have no idea), but doing so breaks the functionality for the button that's already been written. And besides, this seems like a fairly common thing to do - calling a method from a button.
What am I doing wrong? Any help would be much appreciated.
Referencing Dynamically Created Instances Of Class
I've looked up several links but can't figure out why I can't access my dynamically created instances of class in as3... my code is...
Code:
var textPara:textPara1 = new textPara1();
content.addChild(textPara)
textPara.name = "bab"
var maxIndex:Number = content.numChildren - 1;
content.setChildIndex(content.bab as MovieClip, maxIndex);
content.bab.y = 50;
content.bab.x = 500
;
It adds an instance of the "textPara1" class (which I've put in the variable placeholder "textPara") to the display list of the "content" movieclip...
but despite assigning the new instance the name "bab", I can't seem to be able to access it (i.e. when i want to set the x and y position).
I thought it might have something to do with using array [i.e. square brackets] syntax, but already tried that to no avail.
My other thought was maybe I have to write in some sort of code that makes sure the instance has loaded to the stage/display list first and then write and function which references only after that has happened... but I could be talking nonsense!
Please please help. Any thoughts/links very very appreciated.
Cheers.
Referencing Buttons From Class That Extends Movieclip
I'm attaching actionscript classes to my movie clips by extending the MovieClip class and specifying the AS 2.0 class in the linkage properties in the library – with the intention of having basically no code in the FLA.
This works fine and I can respond to events and reference objects contained within that movie clip by declaring a variable with the same name as the object's instance name in the class.
PROBLEM is that the object has to be present on the first frame of the MC, or the class just doesn't know about its existence. I have a short animation on the timeline, and then the btnOK button appears for the first time a few frames later. Problem is that I can't setup any sort of event handler or listener, because when the class is initialised on the first frame it doesn't seem to know about the button.
So in the below code... if the btnOK is on the first frame of the timeline, it traces, otherwise btnOK is undefined.
Code:
class myMC extends MovieClip {
var btnOK:Button;
function myMC() {
btnOK.onPress = function() { trace("clicked") };
}
}
Yeah sure I could place the button on the first frame and show/hide it as needed but that wouldn't be ideal and would make me want to vomit.
By the way, I'm talking about normal everyday button symbols, not the Button component.
Any ideas?
Cheers.

Referencing Main Document Class From A Loaded Swf
Hi,
I'm loading a game swf into what is essentially a shell swf, I'd like game.swf to call a function (myFunction) in the document class of shell.swf.
At the moment I am trying to use the stage within game.swf property as a reference for shell.swf (which extends from movieclip) and then calling stage.myFunction but because the property I want to call is a custom property, it throws an error at compile time saying that the method does not exist.
Any ideas? Is it possible to do this without including the definition for the shell document class in my game.swf? Is it possible to do this without storing a reference to the shell.swf document class - i.e. being able to create the reference from within the game.swf at any desired point.
Cheers
