Let's say Class A has the flash.events.Event imported. Now let's say Class B extends Class A. Why in the hell do i need to import flash.events.Event in Class B? It makes no sens at all to me.
View 3 RepliesSteps:
1)I have created One movieClip & named as MyComp
2)I export this movieclip to actionscript.Class name for this movieclip is MyComp.
3)After that,Dynamically I have created 5 instance for this class & added to stage.
4)Now i need to change width of MyComp. it should reflect on previous 5 instance too.
I tried like, I have created MyComp.as file in same location. There I tried to inherite DisplayObject properties Width.
Runtime error at the line : var mcp: MovieClipPlus =
MovieClipPlus(mc);
It doesnt work.. how can I let mcp inherit the mc?
get a bunch of objects in my library to inherit from (or even be) one class that i have made, but without having to make .as files for every single one is this possible, or is there any other way to give objects another classes functionality in an auto-generated class?
View 3 RepliesI have 1 class (that is extending a UIcomponent) that is representing a component. In that component I create different instances of another class that is also a UIComponent but this class doesn't show up in de first class. I see that it is running and that it has the correct hights but I got the feeling that it doesn't show up with this hights. If I trace I see the width and height is 200 X 200 but there is still nothing visible in my component.
View 1 RepliesIf 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()
package{
public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt

I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?
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.
The use of library classes confuses me once again. I have the following situation:

Is it possible to dispatch event from class that isnt extended class of MovieClip? I created my own class and put import flash.events.Event; import flash.events.*; but when i call dispatchEvent compiler throws error:"1180: Call to a possibly undefined method dispatchEvent."
View 3 RepliesI have created a class (extends the Event class) for use in one of my projects. If I trace the custom event object in the called function I get 'Event' as the type, but if I trace a TimerEvent, or MouseEvent, etc, I get TimerEvent or MouseEvent... Let me demonstrate:
var c:CustomObject = new CustomObject();
c.addEventListener(CustomEvent.ON_SEND_MESSAGE,fnc);

I'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).
I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have this Fla which contains a symbol that is linkaged to a certain class that is in my project. That class inherites a base class named CMovieClip which resides in one of the libraries that is in the class path (and inherites from MovieClip).Of some reason, every change that I do in the base class doesn't seem to influence the resulting linkaged class, much as if this library is cached somewhere that I can't feagure out.I tried to create the same conditions in a separate Fla but it does not repeat the issue.I tried to duplicate the symbol but the issue isn't solved that way.
View 4 RepliesI created a movieclip with a star. Then, I creates a document class and I named it as Main.as.
In that document class I wrote:
package
{
import flash.display.*;
public class Main extends MovieClip
[Code]....
I´m not posting here all the code, but you can easily see that I´m using x_origin and y_origin variables to keep the original position of the movie clip. I will use them to move the star back to the original position.
The problem is that instead of being 20 and 30 respectively, tracing them I see that they are both ZERO. So when I drop the star, instead of going to x=20,y=30 it moves back to x=0 and y=0. I´ve to get the star position relative to stage, but I can´t find anyway!
say that i have a base class called Base, that is Bindable and has a String property like this:

Data binding will not be able to detect assignments to "msg"
is there a limitation with data binding to a base class?
I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;

My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?
I have an mc called sunny. In the properties panel I export her for actionscript. I put Sunny in the main class and Drag in the base class. The reason for this is that I want her to be draggable. I can't use Drag in the main class as another object is using that name. The Drag.as has the drag functionality. Why can't I drag her. I already have a solution - I wrote a specific class for her and extended the Drag class. However, if I have 10 mcs I'm not going to write specific classes for all of them. Summing up: Using the base class Drag in properties panel - why isn't she draggable?
View 7 RepliesI have two SWF files which I shall call container and slave. The slave file contains a movieclip that extends from a class I shall call base. base extends MovieClip and is compiled into an SWC. slave includes this SWC as a runtime library, while container includes it as merged (and does reference it so it should be compiled into the container SWF).
The container loads the slave like so:
bgURLRequest = new URLRequest(slaveUrl);
var context:LoaderContext = new LoaderContext(false, new ApplicationDomain( null ), SecurityDomain.currentDomain);
bgLoader.load(bgURLRequest, context);
When this loading happens, I get the error that class base was not found. I suspect this has something to do with the presence of the ApplicationDomain in there. I'm not sure what it does exactly, since I didn't write this loading code myself (but I do know that it's there for a reason so it can't be simply removed).
I have a program where I have multiple classes derived from a base class. I want to take all instances of the different subclasses and put them into an array. Is there a way I can search for anything derived from the base class?For example, right now a get the number of children, then see what they are, so:
for (var i = 0; i < this.getNumChildren(); i++)
{
if (i is "type")

I pulled the flvplayback component into my library and got the video playback working loading an external FLV in.
Now I want that code in an external class, the problems I am getting with the video and video events
1046: Type was not found or was not a compile-time constant: VideoEvent. 1046: Type was not found or was not a compile-time constant: Video.
How do I import the video component into my external class
I just wondered, what is the benefit of listing each class in imports separately instead of using a wildcard?[code]Is there any benefit at all?

View 1 RepliesI am trying to build a class that inherits from the MovieClip class.Basically I am having issues in the constructor. Since MC's are unique in that they can only be created via createEmptyMovieClip or attachMovieClip, I am at a loss as to how you instantiate the inheriting class in the .fla? I figured if I just left the constructor out of the new class and do the following it would work but is doesn't:[code]How do I inherit from the MovieClip class and still instatiate the class using the above type actionScript?I have seen alot of information about inheritance and AS1.0 (which I have little understanding of).

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 was wondering why my current code for calling a setInterval on a function doesn't work inside my class.I have this code inside one function, calling a second function.
intID = setInterval(selfReferential, dupe, 30, 0x000000);
The selfReferential keyword refers to the current class,but was defined previously (selfReferential = this; ).I get no errors, but the dupe() function is never called.and I had the selfReferential variable replaced with the this keyword at one point as well.
I have a main class which listens for an event dispatched from another class say class A. Also there are other classes say class B, class C etc.There is a controller class.Classes B, C dispatches events that gets listened by the controller and works well.But the events dispatched by the Class A doesn't get listened by the main class.What might be the problem. Detailed Explanation of the problem.There is a main mxml file.
Class files are in:
ProcessInput.as
DBController.as
ShortMemDB.as ....etc
The main mxml file gets the input from a textArea. Sends the input to the capturedInput (input:String) function using set method which is in the ProcessInput Class.Now I need to dispatch events NORMAL, COMMAND depending on the input obtained after the processing, where I'm having problems. The reason is that if the event NORMAL is dispatched a particular function inside the DBController is to be called. If COMMAND event is dispatched then I need to call another function. This idea doesn't work since the events doesn't get listened.But the events dispatched by the CSDB class when listened by the DBController works well.
I created a menu from a created .as extended Sprite class.
Except from this menu, I need it to return a String value of the item name the user selected.
I have my main stage, and I have two objects (blocks), these two objects both extend from the "Block" class. The "Block" class is NOT extended from the Main Class.I would LIKE to call a function, in either the "Block" class or in it's subclasses, from the Main Stage Class. The functions will do slightly different things depending which object you are calling the function (Added different things, and different number of things to an array). What is the best way to implement this?
