How to create object from class that extends MovieClip
Say i have a class name MC
Code:
package {
import flash.display.MovieClip;
[Code]......
why it can't make any object since it is a MovieClip?
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
Just as a technicality, is there ANY object (or anything that can be placed inside of a variable) that does not extend Object?Even the "Class" object extends Object.On a similar note, what is the difference between these two?
[Code]...
I pretty much always use ":Object",but is there any situation where it would be better to use the latter?I also recently found out that there is a difference when using the "as":

1) When your class is used to produce anything visual (Put mc's on the stage)
2) When any part of your class needs to use a property, event, or method of the MovieClip class
I've a strange issue. In Flash CS3 IDE, I linked a MovieClip to a SubSimba class. This class doesn't extend MovieClip (it has MovieClip package as its base) but, instead, it extends SuperSimba (that extends MovieClip). What happens? I instantiate SubSimba in my Flash project and it behaves as I if I called super() inside the SubSimba constructor: is there anyone here who understands why?

I have this class named MovingObject which extends the MovieClip class. This class will be instantianted for several times. Inside this class is a Timer that handles the speed of the objects moving. There is another class called TheStage and this is where I will instantiate MovingObject (s).
public class MovingObject extends MovieClip{
public var tmr:Timer = new Timer(1);
public function MovingObject(){
tmr.addEventListener(TimerEvent.TIMER, Move);
} public function StartMove():void{
this.tmr.start();
[Code] .....
Assuming that the code is working fine (I haven't debugged it), this makes the particles to move all at once. However after several seconds of running it, the particles seem not to be moving in synchronization with each other (because their distances between seem to get nearer). How to make the objects move with their distances each other evened out.
Is there a way to extend the movieclip class without using a library item and attachMovie?
View 3 RepliesWe are developing our app in flash/flex builder for the front end hitting .NET backend webservices. There is one section of the old app that will not be initially converted, so we need have it appear in an iFrame.
So far all that works fine.We shrink the size of the SWF in the host page to just be the menu/nav area. And underneat that I have an iframe control that loads in this page from the old site.Now the problem. in the SWF is a drop down list to enable picking a client. Since the SWF has been shrunk to about 100px high, the drop-down will only occupy within that 100px area which it's opened. This is NOT good as you can imagine. How can I make the drop-down list descend over-top of the IFRAME control and thus extend outside the SWF dimensions? Is this possible?
I tried to make the internal stage transparent and leave the SWF a little larger, about 400 px high, but the IFRAME still appears behind the SWF.
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

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 RepliesThe following is that long only because I gave examples of what I want to know, not because it is complex .I have three basic questions regarding AS 3.0 classes.
1. How can I make a class object interact with an object on stage?
For example, when I have a square (mc_Square) with class "square" attached to it and I want it to trace "Colliding!" and print the X and Y of the mc_Box on contact with an on-stage *hollow* box (mc_Box) that has no class attached to it.how to do it vice-versa would also be awesome .
2. How can I make a class object interact with the same class object? For example, when I have two squares (mc_Square) that both have the class "square" attached to it and when they collide, it prints the X and Y of both of them.
3. How can I make a class object interact with a different class object?
For example, when I have two squares mc_Square1 with class "square1 (that also has a variable Primary=true written in it)" and a mc_Square2 with class "square2"; When they collide, the one with Primary=true would be removed and it's X,Y position traced.
When I use MouseEvent.MOUSE_OUT the target is [object MovieClip], but when I use MouseEvent.ROLL_OUT I get [object Bildspel] - and Bildspel is my class. The thing is that when I use ROLL_OUT I'm not able to delete the targets ENTER_FRAME event.

when we extend a class from a dynamci class should we put the word dynamic after extends
for example:
class dynamic Array{}
class myArray extends Array{}
is this a wirte code?
I'm developing a Rails project that uses authlogic for authentication. And I have a part in that project that is realized with Flex, and I need to know how a user can be authenticated if he or she is logged in or not. I've set up a webservice called UserSessionService and I was trying to get the user who is logged in, but it doesn't work. If I try to get it with UserSession.find, I just get a # as the result (and therefore that's always true).
Here's the UserSessionService.rb:
require 'weborb/context'
require 'rbconfig'
class UserSessionService
def login
UserSession.find
end
end
I tried to extend the UserSessionService class from Authlogic::Session::Base, but that doesn't work either.
I trying to extends ObjectProxy class, the reason is because I want to have a Singleton of the ObjectProxy class, so I made something like
package utils
{
import mx.utils.ObjectProxy;[code]........
when I create my object uniform which is a simple object, I pass it to my UniformObjectProxy.getInstance() static method to get the instance of my objectProxy, ok so far so good.my problem is when I try to bind a property of my objectProxy instance like
_opc = UniformObjectProxy.getInstance(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the dispatchColorChange handler function is called only once an never again, I had check ChangeWatcher.isWatching() and return false meaning my objectProxy is not binding properly, if I create an objectProxy like
_opc = new ObjectProxy(_uniform);
cw:ChangeWatcher = BindingUtils.bindSetter(dispatchColorChange, _opc, data.id);
the binds works just fine, so my thinking is the problem is when I extends the objectProxy class, how is the proper way to do this
My flex3 application downloads XML in e4x format from my web server, and and is left as a bindable XML object locally in my flex3 application. My visual objects then bind to various aspects of the XML object to display the data that I want.My simple program is getting more complicated, and I'd like to extend the XML object and add some functions to it, so I can keep the code that manipulates the XML object separate from my base application. Lets call this new object LoginXML.Can I please get an example of how to extend the XML object in flex3/as3 to create my own custom object with it's own functions. Part of my XML looks like
<nodes>
<node id="1">A</node>
<node id="2">B</node>

Ok, I have spent a little time searching and I can't seem to find an answer to my question, maybe I'm asking the wrong question. here's my situation:
I have a document class called Main.as, this class has variables that instantiate a CreateShape.as class that acts as a superclass. The CreateShape.as class has a protected function that is overridden by other classes (I have a CreateCircle, CreateSquare etc). Those CreateCircle etc classes, use extends to extend the CreateShape.as class, and thus have the ability to override the main method (called newShape()).

I am working on inheritance for the first time. Here is the super class
SetBlank.as
Code:

[Code] .....
I can see the trace function working but the method which sets the text field to blank is now working.
Here is what I want to do...extend the String class Code: class example extends String {} and then I want to take things that are already strings and add a function to them which goes through and removes & and turns it back to & am things got some test code for that here

It is possible for a class to extend an arrayList of objects in Flex?

I come to need a bit more info from my points, so I thought I'd add a previousX, previousY so that I can get a deltaX and deltaY. Now, this works fine if I make a simple self contained class. I think, however, that I'd like to extend the flash.geom.Point class to benefit from the other functions and calculations it offers.
So I extended Point and modified the x and y setters as I needed. When I compile, I get an error that these setters are not marked for override when they should be. So I override, but then I get an error that says these do not override any function.

I was hoping to extend the simple button class in order to have it contain a text field that I can set with code but still have the benefits of the up/over/ states etc... (To set a textfield within a SimpleButton doesn't seem possible with SimpleButton out of the box, you cant reference anything in it).

View 9 RepliesI would like to extend the WebService class in order to add a couple of functions to it. The problem is, when I use the subclass, I get the following message:
'Error opening URL "file:///<PATH WHERE FLA IS SAVED>/undefined"'
The subclass looks like this:
Code:
import mx.services.*;
class com.testing.TestWebService extends WebService{
var foo:String;
//constructor
function TestWebService(){
[Code] .....
The strange thing is, if I extend the MovieClip class instead of the WebService class, everything is peachy. This makes me think there is something that I am missing, or do not know about the WebService class. The code above is the "I want to get it to load without errors" example. My reasons for extending the class go beyond adding a "foo" property. The WSDL path is to my local machine and therefore not accessible to the masses. Any WSDL should recreate the same results.
I am trying to extend the WebServiceConenctor class to make a class that checks a web service at set intervals and has some other functionality. I want to set the properties of the object in the constructor but I cant get it to work, also I want to be able to trigger the webservice from methods within the Check class but I think I have the syntax wrong.

class Check extends WebServiceConnector {
var active:Boolean;
//interval vars
