i've never tried to do this before, so my head a swimming a bit. i'd like to have a public boolean called enabled in myClass custom class. if it's called to be changed, how do i trigger a function from the change? should i add an Event.CHANGE event listener to my variable?
View 1 RepliesIf I have a function and I want to call a variable from another function (only 1variable), how do I do it? I know in the olden days you could set the variable to local or global, but that does not seem to work anymore. There is only 1 variable I need access to, but all the tutorials I have come across talk about making classes for multiple variables.
e.g. function2();
{
variable_b = variable_a;
}

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?
what does public and private mean in this statement and when do I need to use it?this is not my code just using it as an example.

import flash.display.Sprite;

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.
How to configure Public and private IP address in Flash Media Server?
View 6 RepliesIm just starting to get my hands into Action Script v2, and Im having a really hard time working out what the difference is between Public, Private and Static Variables, it seems that declaring variables in these types makes no difference what so ever to the avaliablility of my variables... Could someone be so kind as to put me on the right path?

View 6 RepliesI am developing a chat server were my users log in using any of my clients applications with a very simple implementation of the TCP protocol. When the user logs into, the client sends a raw text to the server indicating some parameters like username, others, and the most important the WAN ip. This data gets stored on ther server database. After the execution of a algorithm who search for other online user in the database, the server sends to a pair of users the ip and the username of the other user, so later the clients can connect to each other directly wihtout using the server anymore. So, the server acts only like a meet point. Well all this works fine is the users arent inside of a private network, like a wireless router. The clients are programed in AS3 using XMLSocket and the server using VB6 with winsock.
View 1 RepliesI 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...
I have the below script as part of a small application I'm building. The script just creates cue-points along a movies timeline so we can add events etc to those cue-points.
[Code]....
It's creating the cue-points well, although I'd like to use the below variable outside of this function.
Code: var stampName When I try and use it I get an access of undefined property error, which I believe relates to the variables being private and within the function - but I can't seem to find a method to get this varibale public.
how bad is this practice? I am having trouble getting to some stuff so i am taking the easy way out

How do I call a private function from an external ActionScript3 document? I'm working in Flash Builder 4, and I need to call a private function from an external AS3 document. I think I've imported it correctly....
import myapp.utils.WebcamFaceDetector;
import myapp.utils.FaceDetector;
But I want to call a function from "FaceDetector". Here's the part of the code in FaceDetector...
public class FaceDetector
{
private var detector :ObjectDetector;
private var options :ObjectDetectorOptions;
[Code]....
I want to call "private function FaceDetector()" to initiate at a certain point in another AS3 file. How do I properly declare it and get it to run?
I came up with a coding pattern to test private functions and variables out of necessity. Assume the project structure below for example. You have separate folders (packages) for your main production code and test code, and each has the folder for the utility for private member access (testabilityutil).
[Code]...
Then, you have PrivateAccessor.as as below in the testabilityutil in the test code side, and you can access to the private members through it in your test cases (MyClassTest.as). Note you can access to the instance members and class static members in the same syntax. (You may notice that the mechanism can be simpler if you don't need static member access.) Obviously, PrivateAccessor.as should be used only in the test cases but never in the production code.
[Code]...
The advantage of this approach is now your test code can get the maximum flexibility to access to the private members with a minimum burden. Also the "instrumentation" is localized as much as possible, so that you can easily eliminate it from the release build using conditional compilation if you want to.
This approach also has cons, of course. You may not like to have a chance to break the encapsulation although it would not happen unless someone intentionally attempted it. You may think it is dirty to add one-line include in your class for instrumentation. You may question the rationale of testing private functions in the first place. It depends on your situation (your ultimate goal, your team structure, the time and resource you have, etc.) whether this could be a cost-effective option, and I would rather not debate if it is right or wrong.
I have a series of calculations i'm doing over a bunch of objects stored in a array. Each function is pretty CPU demanding but if you only run one function, it just works fine.

I'm using exanimo's statemanager class but I dont know how to use this function:
public static function set defaultStateID(defaultStateID:String):Void
how do I call this function?
As I've been working with AS I've developed a collection of utility functions. For example:
$ cat utils/curried.as
package utils {
public function curried(f:Function, ...boundArgs):Function {
[Code]....
And I've found that, some times, I want to keep more than one public function in each file... But ActionScript restricts me to one public definition per file, if that file defines its self as being part of a package.
So, without creating a class with static methods, how could I get more than one public function in a single .as file?
Is there any way to mimic the in operator, but testing for the existence of protected or private fields?For example, this:
<mx:Script><![CDATA[
public var pub:Boolean = true;
protected var prot:Boolean = true;
private var priv:Boolean = true;
[code]...
When I want to see:
pub: true
prot: true
priv: true
bad: false
ActionScript Code:
class Vector2d extends Math {
private var x:Number;
[Code]....
I can't seem to get my private variable, x, to be private. From my understanding of private variables, tracing n.x should throw an error, and adding 150 should throw an error. I've tried changing the variable's name, and the cast type, to no avail. The first trace goes through, the addition goes through, and the second trace goes through.
I'm new to classes, so I could easily be overlooking something vital. But the vars need to be private, because I want to use get/set to update the variables when one or another changes. For instance, if 50 is added to the y value, the magnitude and unit vectors would change, so I want to update them using getMag and getUnit. That whole system would be thrown off if the user had direct access to the properties.

No idea what I'm doing wrong here, it just won't let me access any of my public methods on my class. I just keep getting "Error 1180: call to a possibly undefined method"!

My flex project uses FA-Bridge, and apparently in Safari browser I cannot call any of my public AS functions that have arguments passed in. For example I can call this AS function from javascript:
[Code]....
In the above call safari throws an error # 1063, (i.e. Argument count mismatch) in the safari javascript console, and points to line 561 in FaBridge.js. It thinks I didn't pass in the requied parameters. Now the above issue exists only on Safari. Both of the above approaches work on IE, Firefox and Chrome browsers. Note: I am NOT using swfObject for embedding my swf.
I started making my first complex game and ran into a problem that made me just stop everything I was doing and I have laid the project to rest until I can find out how to fix it.The problem is simple. I have a timer in a public class. The timer is private, but the function to start the timer is public. Only one class calls it. But as soon as the program starts, the timer function executes.Now that aside, why are some public functions being called at the time of the program being executed? The class that executes the function isn't even called until later/instantiated.
