ActionScript 3.0 :: Private Attributes & Class Property Definition Errors
May 22, 2010
I'm setting up functions in a document class file, then from there I am going to call that function from a movieclip in flash. For some reason, maybe I have things set up wrong, but it is throwing me errors such as below: Line 37 1013: The private attribute may be used only on class property definitions. What am I doing wrong here and is there something I am not understanding? Here is my .as code. modal.as > package

I try to serialize objects with their private attributes, in Flex.
The introspection API does not seem to allow it:
"The describeType() method returns only public members. The method does not return private members of the caller's superclass or any other class where the caller is not an instance."
Is there another way for an instance to know the name of its private members?

Here's my code:

The errors are one line 123 and 128.I've googled the error, but I still can't fix it, it's got me baffled for an hour now! I've tried adding curly brace's but still same error. I left line 123 and 128 like this
function _update(e:Event):void
{
_helicopter.update(_mouseDown);
}
function onEnterFrame(e:Event):void
{'
But I'm getting an error stating that _update is not defined

Okay so you've got your private vars in your AS2 Class, you think they're all safe right? Wrong.
Doing a trace(MyClass.myvar); will spit out an error that the var is private and you can't touch it.
But a trace(MyClass["myvar"]); will work perfectly fine. You can use it normal, without any setters getters outside the class.
Is there a way to protect against this? I think this is a huge security flaw. I know it's simple OOP, but a private var in an object should have rules.

I'm trying to make a flash animation but I'm getting these two errors: 1119: Access of possibly undefined property enabled through a reference with static type Class. (line 4) 1061: Call to a possibly undefined method addEventListener through a reference with static type Class. (line 5) This is the code I'm using:
Code: Select allimport flash.display.*;
import flash.events.*;
stop();
buti.enabled;
buti.addEventListener(MouseEvent.CLICK,pla);
function pla(e:MouseEvent):void {
gotoAndPlay(2);
}
My animation is a initial photo that turns around and becomes a black backgroud (were I'll add some text), now what I want is that the photo won't animate until I do a click in it. I used a Layer with a transparent image and converted it to a button and the export name is buti. The other to layers were converted to movie clips named preto and foto.

I'm making an interactive website using ActionScript 3 and no matter what I try and do I keep getting the following error messages:
Characters, Layer 'actions', Frame 2, Line 5 1021: Duplicate function definition.
Characters, Layer 'actions', Frame 2, Line 12 1021: Duplicate function definition .Characters, Layer 'actions', Frame 2, Line 19 1021: Duplicate function definition.
I don't really understand what I'm doing wrong because it says "duplicate function" yet they aren't the same functions. Here is the ActionScript I've used for the first page:
stop();home.addEventListener(MouseEvent.CLICK, goHome);function goHome(evt:MouseEvent):void{ gotoAndPlay("Home", 1)}characters.addEventListener(MouseEvent.CLICK, goCharacters);function[code]....

one thing i've never really understood about AS3 is that you can't have a private set method and a public get method together. from within my class i would like to assign values that would call a private set function:
[Code]...
is there no way to use the set keyword on a private function?

In my project I've defined a Point class to build Point objects. I also built a Polygon class with a (private) array property, Points. The polygon class contains a method getPoints() which return the current Points array. My objective is to built one or more Polygon objects and assign several Point objects to the Polygon's Points array. Let's say I've created two Polygon objects, plgPolygon01 and plgPolygon02. To both objects I insert three new Point objects into the Points array.
As I call the plgPolygon01.getPoints() method, i expect to get an array with three values. But when I do this, I get an array with six values. So I conclude: while I was inserting Point objects into the Points array of a Polygon object, this Points array seems to be public instead of private. Otherwise, I'd only get the Points I assigned to the first Polygon object and not all the Points assigned to polygons.

I've heard it's considered best practice to keep all class properties private and to change them using getter and setter methods.

I have a class which deals with a lot of visuals, which essentially are movieclips. So I have around 50 privately declared movieclips in the class. Would it be a good idea to put them in a dictionary and retrieve them by their name (as key) , put them in an array or just leave them as they are?
My issue is the visual look of my class right now with that many private members, looks like a mess visually.

I have some code from a CS3 app composed of the .FLA file with an .AS file for the class that had definitions for two private classes in it. Yesterday I brought the files into CS4 and noticed that they did not compile. Gives an 1120, access of undefined property and names a constant. I have reduced this problem down to bare bones and it still occurs, so it is a bug in CS4.

there are classes definitions where all their methods are private my question is why are they private, because i've tried a code wherein i changed all the private access modifier to public and nothing changed!
what if you make an instance of that class with all its method private, how are you be able to access that on another class. coz i know private methods are only accessible to the class where they are declared! will the instance of that class be able to access the superclass's private methods!
on private variables, it's still not clear to me as to why make a private variable and then use a getter and setter, when you can simply make it public! are these variables called static?cause on the way i understand it private functions and private variables are static?

I have a class that creates an array from a config xml file. I set a private variable in that class and use a getter in other classes to access the array. The routine that uses the array does the following:
- Call the getter and assign the returned value to a local (private) variable tmpArray. the getter is a simple return() using a value that is established in the constructor.
- Uses a for loop to itterate over the contents
- Uses array.shift() to pop the item in tmpArray
The next time I run the routine, the contents of the array is empty. I'm using the same getter. I implemented the getter when I tried to manage both arrays in the same class figuring that as long as the original array was private (i also tried static), that the value would not change. I have since worked around the problem by moving the routine that fills up the original value from the constructor to the getter. So, consider the following code:
import flash.events.Event;
btn.addEventListener("click", btnHandler);
var myArray = new Array();
var myTmpArray = new Array()
myArray = ["one", "two", "three"];
myTmpArray = myArray;
function btnHandler(evt:Event) {
[Code] .....
If I create a variable myVar and set it to 1 then set myOtherVar = myVar, the both equal the same value. If I change the value of myOtherVar, myVar is not affected. But using the shift() method changes both the original and the copied array.

Currently I have two classes which are "bullet" and "enemy".There are two instances of the enemy class.Code from an ENTER_FRAME event in the Bullet Class:
ActionScript Code:
try
{
for(var k:int=0; k<getEnemys.length; k++)
[code]....
The Enemy Class has a private variable called "hits".What do I have to do in order to reduce the hits of the instance of the enemy that was hit by the bullet?

These two functions are taken out of my as class file, even though the setInterval is never cleared it only calls generateParticles 1 time. Someone please help me figure this out. I have been messing around with it over an hour but still can find why its only called once. emit is a private var Number declared outside the function in the class.

I have a Color class where all the data is stored in a single uint named "_value". However, the constructor for Color looks like this:
public function Color(r:uint = 0, g:uint = 0, b:uint = 0):void
{ _value = (makeChar(r) << 16 | makeChar(g) << 8 | makeChar(b)); }
If I want to create a clone() method, I have to first convert the "_value" variable to an RGB object, then, the constructor automatically converts the object back into a hexadecimal value. Blatent waste of efficiency! However, I would rather have the constructor be user friendly and allow them to type in each color value instead of one hex value (they can use the Color.fromHex() if they really want to, but it does the same as the clone() method and converts back and forth).
Is there any way to instantiate a class without going through the one single constructor function? Any way to set up a private constructor in addition to the public one? Most Visual Studio languages allowed you to have multiple constructors, and the chosen constructor is determined by the passed in arguments. This was really convenient, but sadly, AS3 only allows one constructor, right?

I have thumbnails in a portfolio slideshow movie clip. Each client featured in the movie clip has three thumbnails that when clicked are to show the corresponding image by going to the labeled frame for that image.I used the following code on the first client at frame 1:
//"ace_1" is the instance of the first thumbnail
ace_1.addEventListener(MouseEvent.CLICK, ace1);
function ace1 (event:MouseEvent):void {[code].....
This gave me the "1023:Incompatible override" and "1021: Duplicate function definition" errors.I have 14 clients I have to get similar thumbnails working on.

Why I am losing scope on an array that i define as a private member in a class? I am able to access it from a couple of different functions but in one place inparticular it keeps coming up "undefined". What causes scope to be lost in a function for an array that is defined as a private class member?

I have this sample class
Code:
class TestPrivate{
public function TestPrivate(){};
private function getGo(){
trace("can execute");
}}
And then after instantiate I just calling the method...for testing the "public" and "private" keyword purposing only...
Code:
import TestPrivate;
var obj1 = new TestPrivate();
obj1.getGo();
The result is still can be execute even though I put the private keyword in front of the methods. So what's the private keyword stands for actually...I thought it prevent been get accessed from outside...

Here's my main class:
[code]...
in the timeline I have a dynamic text box named my_textbox: var my_test:main = new main(); my_test.check_DVBViewer(); my_textbox.text = ??Basically the class waits for the callback variable (my_msg). The problem is: I need to set the dynamic textbox text to my_msg variable. How can I access it? I know I can access a public var in the timeline with functioname.variable but I can't define a public var inside a function, right?
