Actionscript 3.0 :: DispatchEvent For Classes Extending Object?
Mar 9, 2010
I've recently come to a roadblock in my code for a non-visual class I created; a sound class if you want to know. At first I coded with it extending Sprite (I can't remember why I started it out that way, but that's the way it was). When I came back to this code, I thought that extending sprite doesn't make any sense if it's an audio class and non-visual, where is no real reason to add something to the stage if you can't see it. So I removed "extends Sprite" from the class and errors started popping up around "dispatchEvent" coded areas. I then tried putting back the extention with "extends Object", hoping that would solve the problem; got the same thing. I've searched with google on why I can't use dispatchEvent on objects or classes not extending anything, but it only came up with how to use dispatchEvent with the usual MovieClip or Sprite tutorial.
I'm working in this website so to avoid getting an error for adding event listeners to the buttons when they are not on stage i dispatch and event in the last frame of the animation, event that is going to be listened by the document class. Until there everything works great but when I try to dispatch an event from the document class to the sound class, it doesn't work.
im trying to port my code to as3 but i stumbled on a problem i have no idea how to fix. error report:

if anyone has any idea why that error happens please enlighten me
Is it possible? If so, what's the preferred way? I'm seeing lots of ArrayUtil and StringUtil AS3 classes, but I don't like using them as it defeats the purpose of an object (StringUtil.trim(str) instead of str.trim()).
I dont understand how extend workes.. when i extend a class,will it replce that class entery point or will a class that extends another have "two" entery points? And can i pass paramters to the extended class?
What is the difference between importing a class and extending a class, I know that when you extend you add all the properties/methods of that class to your own class, but I am still un sure of what this actually does for you and your program, I am pretty confused on the topic and I couldnt find the difference between the two on the internet, also how do you know which one of the two you need to do?
my understanding of extending classes is that you gain all the functions and methods of that class thus You could over ride any one of them. How ever I am confused on weather or not you inherit and can over ride private methods of the class you are extending or if you have to have all methods public in an extended class.
Code: public function SideModule() { if (stage) { init();// stage accessible, call init function[code]....
if i extends thsi class with class B (class B extends class A) how will i get this events in class B? do i have to register for them in class B as well?
I have a library symbol, exported for Action-Script and to Frame1. Now in the document Class, i write
public class Test { public function Test():void {
[Code]....
Now the code works fine but when i write my own (sealed/fixed) Box Class that surely Extends MOVIE-CLIP, statement-2 gives error , i know the Box Class is not dynamic but the Movie-Clip is Dynamic. Now what i understand that Movie-Clip Class being dynamic becomes fixed/sealed when it is extended by any Fixed/sealed Class???
I'm currently developing a game in flash and want to be able to divide up my .fla assets in a way that means artists can work on a game menu .fla in isolation from the game.fla and rest of the game code.If I could briefly explain how I've approached this so far, I would be extremelyMy project is setup like this:HighScoreMenu.fla -> document class HighScoreMenu extending GameMenu class.game.fla ->document class game.asgame.as class loads the published HighScoreMenu.swf and manipulates the menu i.e. animates on and off screen via inherited functions in the GameMenu class.
Now this seemed to work to begin with, until my code evolved and upon going to publish my HighScoreMenu.fla flash started complaining about symbols being used in Game.as that were in Game.fla... If I'm only publishing the HighScoreMenu which extends from GameMenu then why is it even looking to compile Game.as
I'm trying to create a base class for components by extending Group in Flex 4, but I can't seem to define the layout through MXML. Any time I try to move the definition to a subclass of my base component, I get the following error:
Error: Could not resolve <s:layout> to a component implementation.
Judging by that error, it seems that some magic from the framework's side goes into assigning it for a Group and thus the compiler fails when trying to assign it for any other classes. Does anyone know how this is supposed to work? how to allow me to define it in subclasses?
I am creating an object pool to cache some recyclable objects in memory at the outset of my application in order to avoid (as much as possible) the performance issues caused by GC running; if possible I'd like to minimize the memory my object pool reserves, so I'm attempting to pool generic forms of the objects (with no methods) and then casting the generic variants to more specific and complex object types which extend the generic form when I actually want them on the stage.
The trouble is that to do this requires the generic variant class to import/extend MovieClip (because the more complicated objects are themselves MovieClips and make use of DisplayObject methods)-- does simply importing and/or extending a class add to the memory an object takes up when instantiated even if it never uses methods from the inherited class? It makes sense that it would, and some light profiling seems to suggest that it does, but I'm not 100% certain. About how large should an 'empty' MovieClip instance be in bytes?
I have a project that i'm working on, and in the project it's important that i have an object that i can create with actionscript that already has two arrays inside of it. To do this, i made the movieclip, i checked export for actionscript in the library, and in the custom class that corresponds to that object i made the arrays with the following code:
package { import flash.display.*; public class cont extends MovieClip {
classes. GiftMain and GiftItem. i attached GiftItem objects into GiftMain. Actually there are 2 more movieclips between them. i declare a variable in GiftItem as giftMain to reference it to the GiftMain. i have a function in GiftItem which is as below;
[Code]...
trace outputs the right object in this function in GiftItem class but at another place in the same class, it outputs undefined when it is traced even though it is global variable. I just want to reach GiftMain from GiftItem without using _parent or _root. How can i do that?
Is it OK to use the constructor to set properties for a value object class or must I use dot notation and set each one, one-by-one? I recently read an article that was saying I should do it one-by-one as value objects should only contain properties and went on to say using the constructor is not OK (best-practice wise).
Code: ("not OK") var employee=new[code].............
I have 2 different classes that contains different object. And I control from another custom classes on when to load which class. The custom class will load a class when first run, and switch to another one when selected. My problem is, although I called the next class, but the object does not appear. The class that controls which to load
I want to make a flash movie with cars of different kind. Every car looks different and have their own specifications like weight, horse powers, top speed. So.. I want to create a class Car that can hold the variables weight, horsePowers, topSpeed and should be linked with a specific MovieClip (the car).
The problem is I cannot link all my MovieClips, holding the cars, to the same class Car.Should I create a container to associate with the class and then place different car MovieClips in them depending on which car object I'm creating? (so the MovieClip itself is sort of a variable)
I would like to check if object has a DisplayObject as one of it's ancestors and perform some operations on it if it has. Any quick and easy way to do this?
I am trying to get my Actionscript program to turn in a key-value (more specifically: a key, value1, value2) object into a server. I am doing the html request properly, but I'm not sure what kind of object to send;
I'm new to the object oriented stuff and I'm trying to learn how it works. Here's what I've started on - it's led to a few dilemmas. I have one flash file and two .as each with one class. In the timeline of the fla file, it reads: ActionScript Code: var FileObject:ScriptFile = new ScriptFile(); function onEnterFrame(){ FileObject.CallInput(); }
Call input is a function in "ScriptFile.as" that calls another function in "Input.as"; ActionScript Code: class Input{ public function Input(){ } public function keyListener(target:Number):Number{ [Code] .....
In output, when I press Left, it will say -5 over and over again, and I'm trying to add to xpos value but that isn't happening.
Just wonder if I can reference entry point object from any place in the app? Is it maybe assigned to some global object, like stage is for example? Currently I use static methods and variables, but this breaks encapsulation.
I am having problems storing an array of objects, all of which are the same custom class in an LSO and then reloading that array from the LSO without losing the class type of the objects in the list.
I know how to store a single object of a custom class and load it withe the correct class type using the registerClassAlias() function, but I cannot seem to apply this to arrays of objects.
I am trying to save an array called messageList. Each element is a custom class GameMessage with a property called gameLevel. After I load the LSO I am trying to do something like
trace("0th message is from level " + GameMessage(messageList[0]).gameLevel);
And I am getting an exception of like this:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@90fdfa1 to GameMessage.
I have registered the GameMessage class using
registerClassAlias("GameMessage", GameMessage);
and everything works if rather than a list of messages I try and save/load a single message.
TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.common::stageConfig() at cloudsMain() CloudsMain.as which is attached to the .fla

Basically I'm trying to create a class that I can call and centralise any mc on stage by eg.stageConfig.centralisedDO(my_mc), However I encounter the above error.
I have a movieclip on my stage that I am using as a button toincrement an index number. I have declared a custom event class andI am passing the index to the custom event as a property.I have initialized the clips on the stage to listen for thecustom event and I am dispatching the event from the instance ofthe button being pressedEverything seems to be ok except my clips listening for theevent don't seem to be getting it. Can you not dispatch an eventdirectly from a movieclip instance on the stage? Do you have to doit from a .AS file class?
One single swf, imgdesc.swf is being loaded into the emptymcholder, by the moviecliploader instance.My order isfolioholdermc ---holds--> emptymcholder --holds--> imgdesc.swfWithin folioholdermc, I disabled buttons and lowered opacity, once imgdesc.swf was loaded, using onloadInit()Now in the button inside imgdesc.swf. I called, this.unloadMovie(), which successfully unloads the file, but I am still inside emptymcholder, though I actually want to go back into folioholdermc.tener to check for unloadMovie. But my problem is can I place this within folioholdermc, within the onloadInit() or maybe within the on(press) function which actually calls the loader in the first place?? I need to enable the buttons within folioholdermc, and increase opacity, once the imgdesc.swf is unloaded.
Within the onLoadInit() in folioholdermc I added _mc.addEventListener("end",endClip); function endClip() { trace("end"); //plan to insert code to
