Flash :: [F8] Referencing A Static Class Inside Another Class's Instance

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 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

[as2.0 Class] Accessing Instance Variables From A Static Function.
is there some trick to accessing instance variables from a static function?

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.

[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.

Asigning An OnEnterFrame To An Instance Inside The Class's Constructor
I need to be able to add an onEnterFrame event to an object inside it's constructor.

This is what I've tried (it doesnt work obviously):

Code:
myClass = function () {
this.onEnterFrame = function () {
trace("FRAME");
}
}

//------------

myClass = function () {
this.onEnterFrame = myFunct;
}
function myFunct() {
trace("FRAME");
}

//------------

etc...
I've also tried myClass.prototype.onEnterFrame = function...

Nothing I try works, I even created a dummy file to make sure there was no outside interfearance, but nothing worked. I'm able to assign an onKeyDown event, but for some reason it wont work for onEnterFrame. It's kind of important that I'm able to do this for my latest project, so any help would be great.

Accessing Document Class From Static Class?
I am building a family tree like tree in flash.

I have a package TreeManager which holds all my classes.

The document class TreeManaager.Tree controls adding new nodes to the stage.

ActionScript Code:
public function addProfile(relationship:Object):void
{
profile = new Profile();// create new profile

var align:Alignment = new Alignment();//make Alignment object
...

The profile class controls all the internal node functionality.

Question - If I have a button in my node MC (profile class) which should add a new relationship (i.e. call addProfile) how to I do this?

ActionScript Code:
public class Profile extends MovieClip {

public function Profile ():cool:
{
this.addEventListener(MouseEvent.CLICK,Tree.addProfile);

This always throws an error. I can just add the buttons events from the document class, but it would be helpful to know if you can access the document class from a packaged static class?

ActionScript Code:
// add button events
profile.mother.addEventListener(MouseEvent.CLICK,addRelationship);
profile.brother.addEventListener(MouseEvent.CLICK,addRelationship);
profile.son.addEventListener(MouseEvent.CLICK,addRelationship);

Checking To See If One Instance Of Class Hits Other Instances Of The Same Class?
Hi guys, the idea is similar to Yugop.com JAMPACK 01.

Let's say i have a bunch of balls/cells. I'm having trouble figuring out how to make it so that every other ball bounces off of every other ball.

so in short, it's really one instance being able to check all other instances of the same ball class?

any ideas guys and if you dont know what im talking about, please feel free to state that also.

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);
}
}
}

//buttons.as

// Here we define some properties for our text field, starting with giving it some text to contain.
// A width, x and y coordinates.

//myTextField.height=50;

myTextField.multiline = true;
myTextField.wordWrap = true;

// Here are some great properties to define, first one is to make sure the text is not selectable, then adding a border.
myTextField.selectable=false;
//myTextField.border=true;

// This last property for our textfield is to make it autosize with the text, aligning to the left.
//myTextField.autoSize=TextFieldAutoSize.LEFT;

//This is the section for our text styling, first we create a TextFormat instance naming it myFormat
var myFormat:TextFormat=new TextFormat;

// Giving the format a hex decimal color code
myFormat.color=0xFFFFFF;

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

// Last text style is to make it italic.
//myFormat.italic=true;

// Now the most important thing for the textformat, we need to add it to the myTextField with setTextFormat.
myTextField.setTextFormat(myFormat);
this.addEventListener(MouseEvent.CLICK,changePage);

}
function changePage(evt:MouseEvent):void {
var newPage:Number=evt.currentTarget.num;
trace(newPage);

//not working
//1120: Access of undefined property thumbs.
thumbs.dotween("x",700,460);
}

public function dotween(command,startVal, endVal) {
var myTween:Tween = new Tween(this,command, None.easeOut, 0, 1, 1, true);
}
}
}
Any help would be greatly appreciated!!!

Delete Instance Of Class From Class' Method
So I have a class called Unit. When I use this class in a .fla file, I create it by saying:

var unit00:Unit = new Unit(...);

So then it creates a gfx representation of the screen for me. I would like to have a method like this:

PHP Code:

public function remove ():Void { unit_mc.removeMovieClip(); //deleting the gfx representation of the class in the .fla delete instance of this; //I want to delete the variable that references the instance of this class}

So how do I get this to work? I know that delete this will not work when defined inside the class. How do I target the .fla's instance name when I don't know what it will be called?

Thanks for any assistance

[CS3] Referencing A Movieclip Inside A Movieclip From A Class File
Hello All,

I'm trying to access a movieclip inside another movie clip from a class file that is not attached to either movieclip. For instance, I'm checking hitTests for the avatar the player uses on the game, there are two enemy movieclips. Inside each enemy movieclip is another movie clip that serves as a bounding box (specifically around the mouth of the enemy so it can eat the player). Here is what I have so far that isnt working:

Code:
if (_root['otter']['obbox'].hitTest(this) && touch == false) {
trace("Otter touched Urchin");
gotoAndPlay("hit");
_root['otter'].gotoAndPlay("eat");
touch = true;
}
The class file is for the avatar. On the stage is the otter mc and inside the otter mc is another mc called obbox which is what I'm trying to hitTest against. Needless to say, it doesn't hitTest or trace or play the animation. Is there a way to reference a nested mc? Thanks in advance.

Instantiating Character Class Inside Of Game Class
I am having a problem instantiating a Character class inside of a game class.

P.S. I am working on converting http://oos.moxiecode.com/tut_01/index.html these tutorials to A.S. 2.0.

Can I Get The MouseX From One Class's Stage From Inside A Different Class?
I'm working on a first time game using Flash CS3 ActionsScript 3.0 that has a crow class placed on the stage of a main gameStage class. I need to access the mouseX coordinate from the stage of the gameStage class from inside my crow class. I'm attempting to do it via a getter function but seem to be having trouble tracking down the exact proper syntax to avoid errors. Is there any chance I could get an exact syntax example as apposed to hours of online research and study.................8-)

Call Class Method Inside Another Class.
Hello, I have one class that creates another object from another custom class. Then it calls a method from the newly created class. I want this class to then call a parent's method after it's completed.

Something like this:

PHP Code:

//First Class
class FirstClass{
    function FirstClass(){
        var newClass:SecondClass = new SecondClass();
        newClass.doSometing();
    }
    public function doSomethingAfter():Void{
        // Do this after newClass.doSomethign is done
    }
}

// Second Class
class SecondClass{
    private var _mc:MovieClip;
    private var _incrVar:Number;
    function SecondClass(){
        _mc = _root.createEmptyMovieClip(...);
        _incVar = 0;
    }
    public function doSomthing():Void{
        _mc.onEnterFrame = function():Void{
            _incVar++;
            if(_incVar > 10){
                delete this.onEnterFrame;
                // This is where I would now like to call
                // a method of First Class.. but How?
            }
        }
    }
}

I know that I could pass the FirstClass object as a parameter to the SecondClass's doSomething function.. but I was wondering if there was another easier way I do not know about to call the parent or calling classes methods. Or maybe there is a way for FirstClass to detect when SecondClass is finished with what it must do before moving on without having to have SecondClass call a FirstClass method?

Thanks!

How Do I Refer To A Class Instance From Another Class?
Trying to get my head around scope here... I have the following in my root DocumentClass:

var horse1:Horse = new Horse();
var odds:OddsBox = new OddsBox();

From within the Horse class, how can I now refer back to the odds OddsBox instance?

My instinct is to type:
trace(_root.odds);
but that obviously doesnt work here.

Do I have to pass the odds var into the Horse class, in which case, would it have to be declared before the horse1 instance? If so, what if that is not possible - how do I refer to an outside class if it was declared after the calling class was declared?

Thanks lots

[AS2] Self Reference To A Class Instance Within A Class
Hello people!

The question says it, how can I self refer to an instance of a class within the class definition file?

Here is an example

PHP Code:

public function fireBullet(target:MovieClip) {
        Bullet_mc = target.attachMovie("Bullet", "Bullet1", 1);
        }
    }

Now everytime I want to call the function I have to put this as my target, (fireBullet(this))I cannot just put it in the code as it gives me an error. Could someone please help.

Static Class
May be simple question, but...
I've create a static Class. I call it on the main timeline. If I create a second instance anywhere else in the same movie, those two instance refer to the same object. I ceate instance usign MyClass.getInstance();.

Well What I try to understand is the scope of that kind of Class. ie If I load a new swf in my main movie, in that new swf, on the first frame, there is MyClass.getInstance();. But it does not seem to refer to the same object. It's like that new instance, because it is not on the same file, is now a new object???

Does it mean that Static Class Scope is only valid to the same swf file?
If I remove an swf, does it means that all instances of Static Class in a swf is also cleared of the memory at the same time. So when reloaded, all the instance are new???

I thought that static Class was create once in the memory and staying there
Tanx to helping me understand better!

AS3 What Is A Static Class?
I was wandering whether is it required that all the functions and variables must be static in order to be a static class. Like Math.random()

Or having 1 function or variable in a class is static makes it as "static class"?

Edit:
And which way is correct to write this?

public static function AyumiloveAS3():void {}
static public function AyumiloveAS2():void{}

var public static ayuTemp1:int = 0;
var static public ayuTemp2:int = 0;

[AS3] New Obj() Vs Static Class
Hi, guys.

Because we now have the luxury of creating new Sprites and MovieClips etc, I have a question about handling a "tooltip" type object.

Because there should only be one instance of the Tooltip object, would it be better to create a static class and use a Tooltip.init() method, or would it be better to create a new instance of Tooltip each time it needed to be displayed?

For example, if I created a new instance each time, the Tooltip class could contain a static property flagging whether or not another Tooltip is active. If another Tooltip is active then it is closed.

Here's a basic example of what I'm going on about...

ActionScript Code:
package {

import flash.display.Sprite;

public final class Tooltip extends Sprite {

private static var isActive:Boolean = false;
private static var activeInstance:Tooltip;

public function Tooltip( text:String = "" ) {
if (isActive) {
activeInstance.close();
}
isActive = true;
activeInstance = this;
// rest of init code...
}

public function close():void {
isActive = false;
// rest of code...
}

}

}

ActionScript Code:
// Show a tooltip...
tip = new Tooltip("Click this and die!");

If none of that makes any sense then let me know.

Tv Static Using BitmapData Class

Getting An Event From A Static Class
I have a Settings/Config class. All its methods are static. The first thing I do in my swf is to load the settings in the form of an XML file. As the rest of my code relies on this file being loaded, I need to listen for an onLoad event from this Class before running it.

Can't use EventDispatcher as the 3 functions (addEventListener/removeEventListener/dispatchevent) are not static,

So how can I get an event out of it?

Thanks

How To Write A Static Class?
Hi, im familiar working with classes.
Like this:

Problem is, I want a class i can use like this, with no instanciation:

Code:
ClassA.doSomeThing();
I believe its called a static class, can someone help med with this?
Thanks in advance...

My directories structure is: d:flashcvclasses

My fla file is in the cv folder and the as file is in the classes folder.

In my fla file I created a classpath to d:flashcv

When I run the fla file I get these errors:

1061: Call to a possibly undefined method setXmlUrl through a reference with static type Class.

1061: Call to a possibly undefined method getXmlUrl through a reference with static type Class.

I'm attaching the fla and as file, can you please tell me what am I doing wrong?

Thanks,

Sigal

Static Class In Actionscript 3.0?
Is it possible to create static class in actionscript 3.0?
like this?

ActionScript Code:
package {
import flash.display.Sprite;
static public class Last extends Sprite {
function Last() {
}
}
}

Document Class And Static
package {

public class glo {
public static var bal:String = new String();
public function glo(){
bal="asdad";
}
}
}
This class is Document class but my fla not working?!
My fla is only ; trace(glo.bal);
WHY ?

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.

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 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

EventDispatcher/Broadcaster In A Static Class
Hey everyone,

Afaik, you need to instantiate a class to assign a listener to them. That's what I do for normal classes. I use EventDispatcher.

However, there's this class I want to modify - it's used "staticly", much like the Tween class. To clear things up, the class I'm talking about is IntervalManager by kennybunch.com

I want to modify it because I want to be able to listen when a certain interval is complete - much like a tween's onMotionFinished, only I want an onIntervalFinished.

What do I need to do to add this to the class?

Class Static Member Problem
Hi all

i've a problem as following

static function functionshowLargePic_fun(myPic) {
var loadPic_MCL:MovieClipLoader = new MovieClipLoader();
var loadPic_obj = new Object();
loadPic_obj.onLoadInit = Delegate.create(this,resize_fun);
loadPic_MCL.addListener(loadPic_obj);
loadPic_MCL.loadClip("images/"+myPic,largePic_mc);
}
static function resize_fun() {
trace ("ok")
}

error message

'this' is not accessible from this scope.
loadPic_obj.onLoadInit = Delegate.create(this,resize_fun);

What should i replace it

Thanks in advance

How To Best Extend A Static Class To A Dynamic
i wanted to create a Label and attach another variable to it (called "link") and make it a button. However Label is not a dynamic class so i decided to do this:

ActionScript Code:
package {

import flash.display.Sprite;
import flash.display.Shape;
import flash.events.MouseEvent;
import flash.text.TextField;

public class DynamicLabel extends Sprite {

public var link:String;

public function DynamicLabel(_title:String, _link:String) {
//bg
var _bg = new Shape();
_bg.graphics.beginFill(0x888888);
_bg.graphics.drawRect(0, 0, 100, 15);
_bg.graphics.endFill();
this.addChild(_bg);

//text
var title:TextField = new TextField();
title.text = _title;
this.addChild(title);

//link
this.link = _link;

this.addEventListener(MouseEvent.CLICK, clickHandler);

this.buttonMode = true;
}

private function clickHandler(e:MouseEvent):void
{
trace(e.target.link);
}
}
}

However when i run it and click on the "DynamicLabel" object (when the "clickHandler" function in executed) i get this error:

Code:
Property link not found on flash.text.TextField
i want to property "link" to be a part of my class, my object. Why does it look for it in the TextField?

Any workaround is greatly appreciated too All i'm trying to do is make dynamic buttons...

Way To Step Thru Properties Of Static Class?
Hi,
I have defined a class with a lot of properties (about 30). There are a number of simple methods I need to write (eg clone, copy values of all properties from one instance to another, reset values of an instance, etc).

For example

package {
[Bindable]
public class Person{
public var Var1:int;
public var Var2:int;
public var Var3:String;
....
public var VarN:Boolean;

public static function copyInto(src:Person,dest:Person): void {
dest.Var1 = src.Var1;
.....
dest.VarN = src.VarN;
}
}
}

Instead of doing lots of assignments. I'd rather do something like
for each property p in Person
dest.p = src.p

I think this can be done for dynamic classes, but what about static classes?

Thanks!

Can't Make Static Array In My Class..
I have a question class.  Each question can have child questions.  And each question will have a parent question.  My parent variable works fine but it seems that no matter what, my array is static.  In other words, each of my Questions are sharing the same Children array.  Is this a bug/feature or am I just missing something here?

Question.as
CODEclass Question {
    var QText:String;
    var QValue:String;
    var QID:String;
    var ParentID:String;
    private var Parent:Question;
    private var Children:Array = new Array();

    function Question() {
        trace("new question");
    }

    function addChild(childQuestion:Question) {
        this.Children.push(childQuestion);
        trace(this.Children.length);
    }
}

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?

Thanks

Dynamic Class Referencing Question
Quick question, I'm sure this is a stupid syntax problem...

Code:
fighter1_mc.aiPattern="SwoopDown";
fighterPattern = new classes.ai_routines[fighter1_mc.aiPattern](this, 20, 1, 5, 5);
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.

ActionScript Code:
//.fla code

var i:int;

for(i=0; i < 100; i++){
var myBall:flaBall = new flaBall();
addChild(myBall);
}

//.as code

package {

import flash.display.*;
import flash.events.Event;

public class Ball extends MovieClip{

var dx:Number;
var dy:Number;

public function Ball(){
addEventListener(Event.ENTER_FRAME, onEnterFrame2);
reset();
}

private function reset(){
x = Math.random() * stage.stageWidth;
y = Math.random() * 400;
dx = Math.random() * 20 - 10;
dy = Math.random() * 20 - 10;
}

private function onEnterFrame2(event:Event):void{
move();
checkBounds();
}

private function move(){
x += dx;
y += dy;
}

private function checkBounds(){
if (x > 550 || x < 0){
dx *= -1;
}
if (y > 400 || y < 0){
dy *= -1;
}
}
}
}

Referencing Stage From External Class
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 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.

Calling A Static Class Function From The Timeline
Hi there!

I have a (small?) problem when calling a static function in a class from the timeline:

In AS2 I used to do it like this (this code is in frame 1 of the _root timeline):

ActionScript Code:
import com.mypackage.Application;

// call to a static function main() in Application
com.mypackage.Application.main();

how do I do this in AS3, I always get this compiler error:
1202: Access of undefined property Application in package com.mypackage.

thanks for your help!!

Adding A Static Method To The Math Class
I'd like to create a method for generating random integer numbers within a range.

I've already created my own class with a static method and so, but I don't know how to add this method to the already available Math class.

Is that possible?

TIA
