View 3 RepliesI'm trying to set up a menu. Because this menu can have a varying number of entries, I'm generating it instead of hard-coding it. The Menu object contains an Array of MenuEntry objects, and each MenuEntry has a framework.Button object which contains the text and box that actually gets drawn to the screen. I can add a MouseEvent.Click event to the Button, but not the MenuEntry. If I do it that way, though, I'm unable to access the data in the MenuEntry object that contains the button, so I don't know which MenuEntry was clicked.
The only solution I can think of involves checking the mouse position against the position of each MenuEntry, depending on the number of Menu Entries. This does not seem like the right way to do it, though, as it is not scalable. I tried having the MenuEntry class extend the Button class, so theoretically, the MenuEntry itself could dispatch mouse click events, but that didn't work.

I'm just now learning the new object oriented way of scripting. It's been a wild ride, but I've finally learned how to keep script off my frames (very hard coming from as2).Here's my problem:
I have a TextField on the stage in my main .fla file named loadPercent.
I'm loading a jpg with preLoad.as and displaying the bytes loaded in loadPercent.
I can access my loadPercent TextField from my MainClass
but I can't access it from preLoad.as
the document class is MainClass.as
Code:
package
{
import flash.display.MovieClip;[code]....
I get three '#1120 access of undefined propery' errors for each time i try to access loadPercent.
a few basic questions: 1. all my files are in a folder in my documents, not in the flash directory, is this bad? I've seen people using com.whatever etc.
2. my main .fla file does not share the same name as my MainClass.as (it's not named MainClass.fla) Is that a problem?
I'm assuming these are inconsequential because my code seems to work up to a certain point.
I created an flv video player using Flash Builder 4. This "BasicVideoPlayer" project is compiled into a SWC that will be eventually be used to create other video players that extend the functionality. One of the features is a view that appears when the video has finished playing that displays a "Play Again" button. This "Play Again" view has its own class, "BasicPlayAgain", that accepts a graphic asset that is exported from a .fla file that contains all of the graphic/UI assets.
In my new project, "EnhancedVideoPlayer", I'm using the BasicVideoPlayer SWC as a library to create a new video player that will add more functionality to the "Play Again" view; specifically it will add more buttons to that view.The EnhancedVideoPlayer uses a default class that extends the BasicVideoPlayer class. The BasicVideoPlayer class has a member called "playAgainScreen" whose type is BasicPlayAgain. The EnhancedVideoPlayer needs to override the playAgain member and recast it as EnhancedPlayAgain so it can control the new buttons properly.
I have a class, call it MyClass, and there are several variables that I need to be able to access each instance of from within the class.So for instance, I need the object myObject1, a member of MyClass, to store the variable myNumber.From the main timeline, if I trace myObject1.myNumber, I get whatever number I've stored.
However, I need to check the numbers against another parameter, so I need to be able to test if myObject.myNumber == myOtherNumber. But from within the class, if I trace this.myNumber or myNumber I get null.What is the proper syntax for accessing a variable within a class?
This is for AIR: My document class imports a separate class "ConnMonitor" and uses it to constantly monitor the network connection. It's at the very end of that class where it's supposed to update a textfield on the stage as the connection changes, but the class can't access the textfield.

I am having trouble referencing dynamically generated textfield in a document class. I gives me the assigned name when traced, but generates an error when I refer to the name. Here are the documents:

I know that one can give a symbol already placed in the scene and instance name and be able to manipulate that object programatically through ActionScript in Frame actions. What I want to do instead, is bind that instance name to a class member so I can use it inside a class file and and eliminate the need for frame scripting.
I am new at this and I'm trying really hard to figure out what the ideal workflow is. I would like to use a fully OOP approach at developing my applications, however I like to use the graphical interface to position assets on the scene because I find it easier than positioning assets programatically. So the solution I am looking for is binding assets to class members. If such a workflow is not possible, what's the best approach in dealing with assets in a fully OOP design?
I have an actionscript class with a static member variable defined.

How to populate a flex datagrid from an Arraycollection without specifying DataGridColumn's individually.

I am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
[code]...
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
"Access of undefined property currentState."
I have the following inheritance structure:

this.x = AvEnvironment.xs // public property in this class
this.x = parent.xs
I've also tried something like this:
var ev:AvEnvironment = AvEnvironment(parent);
this.x = ev.xs
but I get a TypeError. Error #1009: Cannot access a property or method of a null object reference.
How to access a display object on the stage in a class which is not a document class?
I am looking for a solution that doesn't involve passing the stage as a parameter to the class.
One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.
I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?

Despite having lots of posts on the web regarding this, none of the solutions worked for me In my document class (Main.as) ve two containers.

My first experience is build an aquarium with a lot of fish swimming, and they can be clicked. When one of them is clicked we should receive a trace message saying ("I�m a Fish!"). To do this, I thought that the best way will be:
1- create a document class, named Main.as
2- create a base class, named Clicked.as
2- create a movie clip with a fish.
3- export the movieclip to actionscript. In the mc properties set Class as "fish" and Base Class as "Clicked".
Say you were importing flash.events.KeyboardEvent and you wanted it to extend the MovieClip class, is this possible? Where you dont have access to the class to just type "extends XXX"
View 14 Repliesi have a game that i want to put load screen on, which i created a separate class for. first the main class is initialized and in the constructor function, it does an addChild(loadScreen) which places an instance of the loadScreen MC on the stage. within the loadScreen is a "Play Button" that when a user presses this button i want it to continue startGame in the Main class. the way i tried it was Main.startGame from the loadScreen class, but that obviously does not work. is it possible to call a function from a different class.i have three files:
Main.fla
Main.as
loadScreen.as

Code:
package

I'm struggling trying to get the correct (assuming it's possible) syntax to get access to a textfield in a movieclip via a button also in the movieclip.
Here's the specifics:
var statue:MovieClip = new mcStatue;
In mcStatue is a button: btnStatue, and a textfield named Qty.
On a mouse click to the button I want to be able to add to the Qty textfield.
e.target.Qty.text = "x"
game me: Property Qty not found on fl.controls.Button and there is no default value.
Is there a way to do this, or do I need to go after some kind of workaround?

var level:MovieClip = this.object[levelString] as MovieClip;
var bronze:MovieClip = level.bronze as MovieClip;
But when I try to get my textfield:
(bronze.getChildByName("levelNumber") as TextField)
