I'm trying to make a class that extends the Sprite, have some private properties attached to it and be able to read and write those properties using getters and setters. Simple... but the compiler throw this error "Access of possibly undefined property speed through a reference with static type flash.display:Sprite."It works if I set my class to extend the MovieClip object.Could someone explain me the logic behind this? why I can't use getter and setters with a Sprite?Here is a sample code:
package {
import flash.display.Sprite;
public class Vehicle extends Sprite{

I'm having trouble updating a property value of a custom class (SubLoader) using a getter and setter. Inside the if() statement of the main fla you can see my attempt to set the percent value. Running a trace() method before the if() statement always outputs '0' for some reason. Tracing after the if() statment outputs an actual value. I can't figure out why the percent property always traces as '0' before the if statement even though I am updating it with each progress event.

Anyone know a workaround to make static getter/setters?
View 2 RepliesI seem to have run into a situation where when I push a value to an array held within a singleton via a getter/setter , Flash seem so access the getter over the setter method. Within my command/controller (I am using RobotLegs)
override public function execute():void {
// various line of code here
//Place screenshot image into an array from model for later reference.
model.unitScreenshots.push(screenShot); // screenshot is just a Bitmap object
}
The getter and setter within my model e.g. robot legs singleton
public function get unitScreenshots():Array {
return _unitScreenshots;
} public function set unitScreenshots(value:Array):void {
_unitScreenshots = value;
}
When I set a break point on both the getter and setter, only the getter method is being called, why? I would think that a push value on the array would trigger the setter, not the getter.
I'm trying to create a property that can be set by extending classed and read publicly.I couldn't think of a good naming convention for a protected property with a public getter, so I tried to do this:
public function get name():String{ return _name; }
protected function set name(string:String):void
{[code]......
However I get the error (when trying to set name in an extending class): 1178: Attempted access of inaccessible property name through a
reference with static type testing:TestComponent.1059: Property is read-only.
If I change the setter to public, it works fine.
I recently completed a tic-tac-toe game in AS3, using some simple function-based code I had written in C many years ago.Now I'm on a quest to do it the "right way" using OOP techniques and best practices.Everything is now divided into neat little packages, it looks pretty, and the last part of my journey is to get all the little buggers to communicate with each other.I want to move the code which holds the game state from my main to it's own class in com.okaygraphics.model.GameState.The problem is nearly every other package gets and sets these game state properties.I'm trying to figure out the simplest way to encapsulate this stuff, while still allowing my other classes to access it.
1) Do I need a constructor? I mean, my program will never have more than one GameState. If I should call my getters/setters as instance methods, how do I get each other class to reference the SAME instance from their respective packages?
2) Do I even need getters and setters? Perhaps the class could just have 3 public properties? If so, how would I acheive the proper scope with regard to my other classes?
3) Should I assign everything to the class itself using the static keyword? If so, how would I implement and use those static methods?
4) Is this a mistake? Did I totally just program myself into a corner?
i dont get the advantages of using getter and setter instead of setting the var public.
View 7 RepliesI have two functions one that sets and one that gets a number. The set one works, but the get one doesn't. I have it trace the set it returns the correct number, but when I set the getY function, it doesn't give me anything at all. When i took the number out of the trace it just gave me back only text. What am I doing wrong here?

I have written a class, which is basically a textfield for forms. It will eventually have several validation modes built into it too, which will be set by setting a property of the object.anyway, my problem. Basically my setters are empty if the movie is used as a loaded swf within another movie.I have an Event listener within the class listening for the Event.ACTIVATE event (still not sure exactly what this does...) though i do know that i need this in place for the setters/getters to work.If i create objects from my class, set some properties everything is spot on, though the moment i load this working movie into another movie the Event.ACTIVATE does not fire.[code]Now, if i run this movie its perfect - everything works as it should, right down to the validation.however, this movie is to be used within another movie. When i load this movie into a parent movie my fields aren't added to the movie.
View 5 RepliesIs it possible to have a property with a public getter and protected setter? I have the following code:
public class Mob extends Sprite {
// snip
private var _health:Number; // tried making this protected, didn't work
public function get health():Number { return _health; }
protected function set health(value:Number):void {
[Code]...
I did have this.health -= dmg; but I split it out to get more details on the compiler errors. I don't understand how the property would be considered read-only within the same class. I also don't understand how it's inaccessible. If I make the backing field, getter, and setter all protected, it compiles but it's not the result I want; I need health to be readable externally.
I have a problem whereby in AS3 using Flash Builder 4 using a public getter with an internal setter gives me the error "property is read only", like so:
[Code]...
If I've got a getter method, say a(), that returns the private variable _a. Obviously from outside the class I call instanceOfClass.a. But from inside the class, should I use the getter or directly _a? Suppose I'm writing a method that uses _a: should I use _a or a? var b = a; or var b = _a? Maybe for performance reasons it's better to directly access _a? Or since there's a getter a(), it's a good practice using always and only the getter?
View 8 RepliesThe generally used workaround for this, is to use a regular function instead of a getter/setter. This results in having to have ( ) after the function variable obviously. The question is, can a Function variable be assigned to a getter/setter function and retain its attribute of not needing brackets.
Below is some Pseudo code representing the question:

public class Foo(){
private var prop:Object;
public function get Prop():Object{return prop;}

I have an issue with the attached project (Flash 8). On the rollOver event, the shapes are supposed to turn yellow. On the rollOut event, the shapes should fade back to blue.It works well except in the case when you quickly rollOver then rollOut several times (try it with the largest shape at the bottom). If you do it fast enough, it seems to get hung on 'blue', the initial color.
View 2 Repliesstill trying to get the hang of the intricacies of arrays. I have two questions:
1. referencing variables with function inputs. Say for example i do this:
Code:
myfunction(input:Array):Array
{
var myvariable:int;
[Code].....
of these three codeblocks. what is most correct ? i'm rather fuzzy about when i should use "new", and whether or not i need to explicitly cast from arrays.
I'm very much a noob in terms of actionscripting (I use MX), and I was wondering if I could enlist your aid. For right now, I'm trying to get the hang of Duplicated MC's. Right now, my practice animation is like this: A one frame movie clip with actionscript tweening a black ball. Basically, my AS just makes it move to the right as it gets smaller and fades with alpha. This part works fine.
I put this above movie clip (ball, let's call it) in another MC. Now this MC (let's call it BallTween) has AS on it which duplicates the ball movie clip 30 times with a for loop (q is my incrementing variable). Now I read a tutorial on a forum that suggested using a mc = _parent['newball'+q] to control the duplicated movie clips as they are generated, but this doesn't seem to be working for me. Is there any really comprehensive tutorial on this kind of AS around? I would really like to get good at manipulating duplicateMovieClips. Does anybody have a simple way to do this from the ground up, instead of solving a problem in an existing flash project?
In the attached file, for some reason, when the menus drop down, they frequently get hung up. (stay down, slow to move back up into the hidden position, etc.)

I am attempting to insert text from a database into a custom TextArea component, using the following:
var front:CaptionTextArea = myFlashcardFrontsides[adjIndex] as CaptionTextArea;
var back:CaptionTextArea = myFlashcardBacksides[adjIndex] as CaptionTextArea;
var passage:CaptionTextInput = myVersePassages[adjIndex] as CaptionTextInput;
front.text = passage.text;
back.text = str;
This works 100% of the time for smaller strings. However, if I insert long strings of text, the application will hang consistently. The maxchars for the textarea is set to 1200, and the text that is inserted into the text area is always smaller than the character limit:
backside.maxChars = 1200;
I wanted to create effect in AS3 like initially image is still and when I pull image then that image should drag and hang. And, when I again start dragging that particular image then its registration point should change and image should hang on new registration point.

After that, the video is resume when instream ad complete.
View 1 RepliesI have a photo gallery that is XML based. In IE everything works fine. In Firefox, the gallery will load all the thumbnails and then hang up when loading the large image. The trouble is this only happens on the galleries that have a lot of images in them. It works fine with smaller galleries. Since it's xml driven, the images are not loaded until called for and all the thumbnails get loaded. I did see a post about a var being collected for garbage if it's defined inside a function, but I've tried to limit that to just declaring a new image to be displayed. My site is: [URL]. If for some reason you get a page saying that this site is under construction, click the link to the gallery again. I don't know why that keeps bringing up an old page.
View 2 RepliesI'm having a problem that I'm not sure is necessarily tied to the Flash, but I don't know what the root of the problem is yet.I have a SWF that connects to a socket using the Socket class. This works fine.I'm also making (jQuery) $.getJSON() requests to load certain page data. This works fine.
However, when the Flash socket is connected the Ajax requests stop being sent. By this I mean that it seems that the HTTP requests being made are stored in a queue while the socket is connected. As soon as I disconnect from the socket the HTTP requests continues to load fine. The HTTP request never times out (as it's not even being sent to the server), but just hangs there waiting...until I close the socket connection.
I've verified both in the jQuery and Adobe docs that both the Ajax (JSONP) requests and the connections using the Socket class are asynchronous, so I'm really confused as to why the socket connection would block the HTTP requests.
I was trying to load an external SWF (that contains the below code in its document class) with the Loader class but i keep on receiving Error #1009: Cannot access a property or method of a null object reference. So i tried to use the event listener Event.ADDED in MyDocumentClass constructor of the external SWF to let the document class be part of the display list before i invoke createRandomGraph. But when i place createRandomGraph( ) inside onStageReady, The compilation process hangs. When i leave the createRandomGraph( ) inside the constructor, it works perfectly as stand alone but will produce Error 1009 if loaded within the loader SWF
public function MyDocumentClass( )
{
this.addEventListener(Event.ADDED, onStageReady);

Since i upgraded to Flashplayer 9.0.124.0 i've noticed that using textures on 3D Objects via the beginBitmapFill method and setting the smooth attribute to 'true' causes the player to hang a few milliseconds at random. Setting smooth to 'false', the player runs without any hang. I tested this on different machines. An upgrade to player 10 beta didn't cure the symptoms but the hangs appear less in time. Has anyone else such problems or an idea what is going on?
