I have a class like this..
public class Doc {
public function Doc():void {}
public var myVar:Boolean;
}
How can I know if the value held by myVar is default false, or someone has assigned false to it? Isn't there an undefined state? How can I achieve such a thing?
This is the code i've got, basically checks finds the x,y position of number 2 in a multidimensional array. For some reason sprite.px = x and sprite.py = y give undefined messages when i trace them. What am i doing wrong?
[AS]
for (var x = 0; x<map[x].length; x++) {
for (var y = 0; y<map.length; y++) {

is it better to use public variables or public static variables?
View 6 RepliesI put this code on the main time line:
Code:
var myVar = "something";
if I make create a movieclip and on the first frame trace(root.myVar) I get this error:
Quote: 1119: Access of possibly undefined property myVar through a reference with static type flash.displayisplayObject.
Why? Even if I use the target tool in flash and choose Absolute it gives me 'root' for my main time line.How can I get my variable off the main time line with an absolute path?
I have a base class "Vehicle" and a derived class "Car".
[Code]...
Basically, I want to set a vehicle property in Car's constructor, call Vehicle's constructor with super() and have Vehicle do something based on myVar. But this is the output i get: car pre: null car post: car vehicle: vehicle Why does myVar not keep the value of "car" when the base class constructor is called? How am I supposed to implement this correctly?
I have a class called (DropDown.as)In that class I haveCode:public static const DROPDOWN_CHANGE:String = "Drop Down Changed";In my document class (Main.as) I instantiate my class and try and trace my public static constant but it outputs undefined:
Code:
var dropDown_mc:DropDown = new DropDown();
trace("Public Static Constant" + " " + dropDown_mc.DROPDOWN_CHANGE);

This might be a very stupid question, but I have to ask it anyway. I am graduating in about a month and while studying, I have always been taught to use properties instead of public variables. So I started wondering what the advantage was and I must say that in some cases, I have no clue at all. Of course it is handy when some other logic needs to be executed when setting properties or getting properties, but is there any advantage to using properties when you are only getting/setting a variable? An example of what I mean is shown below (As3).

I have a simple problem which is not easy at the moment. this is a text field class which add a text field to a movieclip (passed from root class) and also save(buffer) some data (like xml file name) in it`s public variables:
package src {
import flash.display.Shape;
import flash.display.MovieClip;[code]............
.. now I use a for loop to add instance of that class to a movie clip on stage:
for (var i:int = 0; i<Bunker[0]["trans0size"]; i++) {
menuData[i] = new menuitem00(i, menu_mc, Bunker[0]["transfile0" + i]);// pass i , a movieclip named menu_mc and an xml file name
menuData[i].name00 = Bunker[0]["transtitle0" + i]; // pass text
menuData[i].activateFlag = true; // set actveFlag to true
menuData[i].init(); // run init() inside the instance. it adds textfield to the menu_mc and also set name00 as Text for the textField
}[code].........
I want to get "xml00" var from that instance on the stage by mouse click but, trace (evt.target.xml00); is not working .. also trace (evt.target.name00); is not working. I can get everything like .alpha or .text from txt00 but not other variables in my object.
I have a bunch of variables I need to pass to some class from frame where I instance classes. Is there any other way do make Class read that variable values beside this?
Sample:
ActionScript Code:
var _imgPaddingVert:Number = 2;
var _imgPaddingHor:Number = 3;
var _minTopMargin:Number = 30;

I'm literally new in AS3 and slowly trying to migrate in thats why im here seeking for help. Can someone help me how to access/control a certain public variable in a loaded swf from the main swf? this problem has been paralyzing me for days. (sigh...) [code]...
View 1 RepliesI'm writing code that takes data from mysql that's processed by a PHP script. It's actually a bit bizarre, at least to me. Anyway, here's some basic AS3 code that's moving toward what I want to do:
var loader:URLLoader = new URLLoader();
var urlRequest:URLRequest=new URLRequest("receive.php");
urlRequest.method=URLRequestMethod.GET;[code]....
For some reason, the statement "trace(evt.target.data);" produces a whole pile of garbled text before the actual stuff that it's supposed to show Because of problem #1, I've had to include a throwaway variable at the beginning, otherwise the first variable I try to pass into AS3 comes back as undefined. This causes errors when I run my flash movie in the IDE, but when I run it from the browser it doesn't seem to have any effect.But this is the strangest thing of all whenever I make any changes to the database (and subsequently try to load data from different variables), the new variables come back as undefined. For example, let's say that I add another entry to the database, and decide to load students 2, 3, and 4 instead of 1, 2, and 3. When I do that, any new data I've added comes back as undefined, even though when I view the PHP output in my browser, it looks just fine.
And now for the REALLY bizarre part: I'll copy that output, paste it into my PHP script as an echo statement, comment everything else out, and my flash movie runs fine. Even though the output from the PHP script is exactly the same, it gives me errors.
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 embeded swf like myswf.swf?myVar=test.txt ,i get by _root.myVar (test.txt)how can i get this parameter in AS3? I have searched google but no success
View 3 RepliesI've been searching this problem for a while and have tried a number of solutions found on google but nothing has worked so far. I'm sure this is a common problem, but due to my lack of flash knowledge I can't logically work through it as I'm used to windows form development, it makes sense to me that the function could access the variables I have defined but they dissapear after the .onLoad event. Does anyone know the common solution to this problem? I want to be able to pass the xml details into the local variables so I can pass on the details into a dynamic text field when movies are hovered over etc.

I'm trying to extend a class like panel so that I can fire click events only when the title area is clicked on. The title area is a protected uicomponent of Panel called titleBar. So I want to make that component public.It seems like I'm almost there but I'm getting a "TypeError: Error #1009: Cannot access a property or method of a null object reference." when it tries to add an event listener to the titlebar.
here is my extended panel
package custClass{
import mx.containers.Panel;
import mx.core.UIComponent;
public class ExtPanel extends Panel{
[code]....
And then this in the AS:
newPanel.getTitleBar().addEventListener(MouseEvent.ROLL_OVER,over);
Still getting the same error.

I have been working on a Flex Mobile application using Flash Builder 4.6. I have 2 mxml 'views' in my project. In one mxml file, i have a function that grabs xml data. In my other mxml file, I have a refresh button that when depressed is suppsosed to call the function in the first mxml file in order to once again grab the xml data. I dont know how to call that function from outside the mxml file it is housed in. [UPDATE #2]* I thought I should share some more details about my issue.
It is a reddit client mobile app. It fetches the feeds, etc. In my main view called RedditReaderHomeView.mxml, I am using a splitViewNavigator spark component to house two other views like so:

I have a flex application which collects data entered by the user and posts it off to a web service I have running on a back end server. The flex application does not authenticate users (it's available for anyone to use without setting up an account) and communicates to the web service using HTTPS. There is an XML firewall in place for preventing certain malformed requests, DoS attacks etc and the web service validates all data received from the client.
If I was to sign the content then I could use the XML firewall to verify the signature but I assume that any certificate type data I embed in the client could be extracted out of the flex app through some means of de-compilation. My question is, is there any way of limiting calls to the web service to only those from my flex client? I understand that a user could input bad information but I'm really trying to prevent another client or 'bot'.
I have a datagrid with itemRenderer in datagridcolumn as my custom component(c1). I am getting the dataprovider data in custom component by overriding the set data function, it is fine. But now my custom component(c1) is also having another custom component(c2).

How would you go about calling the public properties and methods of a SWF you load in actionscript?

I work with Flash CS4 and lately I've been looking for certain classes to ease my work. To be more precise Atom/RSS2.0 parsing classes. But the best result I found needed me to work with FLEX. Now I can't get this to work with flash CS4. There's no apparent way to make this work. I can build my own parser or look for one that doesn't need Flex. But it looks like the future is more FLEX oriented.
EDIT : I know how Flex Code and SWC files should work. But every time I try to use them I get some bizarre error about missing classes and methods that are part of FLEX but not included in Flash...
