ActionScript 3.0 :: MovieClip: Parents And Sharing Class Definition?
Jan 15, 2010
Is there any way for movieClips to share the same class definition?When you have alot of objects to keep track of it becomes a pain to have to write separate actionscript files to do the same thing.For example if I:Create an actionScript file which extends movieClip with the name ClassX.as with all the nescessary code incased in package{}I try properties>export for actionscript>ClassX.as for two movie clips (each with different graphics).An error occurs on the 2nd movieClip complaining that the class I used was not unique. y other question is how do I make an actionscript file file that both extends a movieClip and another class.For example:In a game there is a movieClip for an enemyShip1 with its own class definition contained in an actionscript file (defining its behavior)There are 2 child objects enemyShip2A and enemyShip2B each of which have there own images,class definition but which inherit all the functions from the enemyShip1Class.It would seem that the logical thing to do would be:
package
{
//import extentions.*

I have a class definition as file. In it a variable gets passed to into a function (parameters). Then I want to use the name of this function to swapDepths with another movieclip.
Code:
private function alphaZero(clipToSwap) {
trace(clipToSwap+"+clipToSwap");

I've been sorting through the XML docs and i've bumped my head into a bit of a question. So, to preface, I have been able to load the XML successfully, but I want to be able to use my own XML loader class to load the XML and then be able to reference it from the document class. Also, I'd like to be able to send a file path to the loader class when I call it.
The document class:

This is my first post. I'm new to actionscript, but not to programming. I hope to learn a lot from these forums. To the point: I decided a few days ago that I wanted to create a flash game. I'm taking an object-oriented approach to the game design since that is what I know. The issue I am having is that I have a class called Hero that inherits from a class called Entity. Now my issue is that I don't want Hero to call the Entities class constructor when I initialize a new Entity.

I have several buttons on an externally loaded swf that work fine but I'd like to clean up the code if possible. Is there an better way to target the mc other than using multiple _parents?
Code:
on (rollOver) {
_parent._parent._parent._parent._parent._parent._parent.expression.gotoAndStop (2);
} on (rollOut) {
_parent._parent._parent._parent._parent._parent._parent.expression.gotoAndStop (1);
}
The thing is I am not exactly sure if this mc is going to remain an external swf or if it will eventually stand alone, which is why I haven't targeted the root at its level. I'd like it to work either way if possible.

I have two MovieClip symbols in my library and I want them to share the same class, but Flash doesn't allow me to assign the same class to any two different MC symbols, so instead I created two bogus classes which extend the class I wished to share initially.
So having two MC symbols defined by 2 different classes extending a different class allows me to share the same piece of code.
My Question: is there a better was to share a class between 2 or more different library symbols?

In my library I have a few symbols (with diffrent graphics) that I want to share the same class (the same methods I written in as3).
First I tried to set the same name on the class line when converting to symbol but Flash then tells me that the name have to be unique. So I tried diffrent ways of inherit the class in each symbols custom class, but I didn't get that to work either..

I have four instances of the same class called Tile, that is bound to a movieclip with four frames. They're imbedded in a movieclip that I'm using to hold all of the visuals.In the main class of my .fla I declare a variable called menu1 that is bound to another movieclip with 2 buttons on it.
I'm trying to make three things happen here: on clicking the Tiles the menu will pop up over the tile that was clicked; that on clicking another tile when the menu is already up it will close that one before adding a new one; and lastly, that on clicking the second button in the menu, it will change the frame of the tile clicked and close the menu.The tile.as has an addeventlistener in it's construction method to add the function onTileClick to each Tile.
public class Tile extends MovieClip{
public function Tile():void{
addEventListener(MouseEvent.CLICK, onTileClick);[code]....
This works fine for one tile. I can click on it, the menu pops up, I can close and reopen the menu as many times as I want, and I can use the other button with no problems.Also, clicking around on different tiles moves the menu around without repeatedly adding it, so that seems to be working fine as well.The problem is this: If I click on a tile, close the menu, then click on another tile and close it, I get an error 1009.It still closes, that error just comes up. And it will come up for any more tiles I open and close it on.Then, after clicking on however many tiles, if I do click the advance button, it affects all of the tiles, and I get an ArgumentError: Error #2025 for each tile clicked on.I tried adding a variable that held the event.target value in the onAdvance function, and using that for the gotoAndStop, but the same thing happened. When I tried tracing the name of the variable, I noticed that it was tracing the names of each tile clicked with each subsequent trace.
Am I building this all wrong?I thought that making a class for my tile object, and adding eventlisteners to the class, and adding the functionality of the tiles inside of the class would be good practice for Object Oriented Programming, but it seems to be producing nothing but errors. When I defined these tiles inside the main timeline, with separate event listeners, I didn't have this problem

in my last flash website i built, i created a gallery, my way of creating pages in flash are to have a movieclip as a page, so to make it easier to switch between the paged (page switching functionality is purely done in AS3). the gallery was a problem however, i needed the pictures to appear as popups, however to add the child from inside the movieclip, any masks i use would prevent the popup from leaving the immediate area of the page. so to get around this problem i basically used: MovieClip(root).addChild()
in my opinion this was a mistake, because it created other problems. the problem was that the popups are still connected to the page, even though they are outside of it, which meant that using removeChild() to switch from the gallery, meant that any popup that were still active, 'DIDNT' dissapear, and worse than that, because the page was removed, the popups lost any AS connected to them, which meant the couldnt be removed at all.

Any way that I could get a variable definition straight from a class (or some sort) without having to create an object and read it from the object. Basically I need to know a whether an object will have a specific true or a false variable definition but I don't need to create the object right away for anything else. It seems a bit of extra processing to create an object I may not use for sometime but just needed to know a true/false early on. I can give it the name of the class just hoping to bypass the object creation and hope garbage deletion will take care of it.

I came across the following issue:
- I am loading a particular FLA (let's call it Module1.fla) which contains a Symbol with an associtated class "FakeImage1"; the class file DOES NOT exist,s Flash creates it when compiling the FLA. This FLA has a Document Class (Module1.as), in which I instantiante FakeImage1 (which is a different asset/graphic) by calling ...new FakeImage1()
- then, I am using a custom ModuleManager to unload Module1 and load another SWF (Module2.swf/Module2.as). This one also has a FakeImage1 Symbol in it's Library and also instantiates it in the Document Class.
- now, assuming that I am correctly unloading Module1 (in my ModuleManager) before I load Module2, why is it that FakeImage1 in Module2 is instantiating the same asset that was instantiated in Module1 ?It seems that the automatically-created FakeImage1 class is still in memory (or wherever Flash puts it) when I load Module2 and therefore, my *new* asset isn't being loaded - instead, the first one is.
Note1: I DON'T want to use class/as files for my Library symbols;
Note2: of course, I could just use different class names in my modules/flas, but le'ts assume that I don't want to do that

I'm trying to rewrite a procedural ActionScript program as an OOP one: in the procedural version I set up event handlers for movieclips on the stage with a loop and it worked fine.However, when I put these event handlers in a class definition, it's no good. Simplified version below, which is just supposed to make a sound when the user clicks on the boxclass definition:
class Event_stuff {
var nLpCntr1:Number = 0;
var nNumberOfChoiceBoxes:Number = 3;wrong use of terminology

I get this confusing message every time I start a new flash project and I dont know why. I understand what the message means, but its simply not true so that bugs me. My project so far consists of exactly one AS file so far: CMain.as, which contains exactly one public class: CMain. The file lives here: C:FlashProjGameasCMain.as. n my .FLA, I have set CMain as the Document class. In File->Publish Settings->ActionScript 3.0 ClassPath, I have added "C:FlashProjGameas".
When I press "OK" from this screen, I get this message: "A definition for the document class could not be found in the classpath, so one will be automatically generated in the SWF file upon export." On my last projects I think I have just ignored this message and everything worked out ok. But this time I want to know what the hell it means. My CMain class is definetly in the classpath, so what the heck is this message talking about?

I have two Flash Builder projects. Let's call them MainWeb and MainAIR. MainWeb defines and includes all of the classes for my application including a runtime loaded module that interfaces with our web services. MainAIR's Source Path references MainWeb/src and includes only two unique parts. The first file is of course the root MXML document. The other file overrides a compiled, runtime module defined in MainWeb called DataStreamer. DataStreamer interfaces with our web services for MainWeb and the alternate version of DataStreamer interfaces with the OS filesystem for MainAIR. This makes a very easy to maintain pair of projects and easy to build both the web version and the AIR version of my application.
It has worked well until I needed to add an instance of mx.controls.Image. Image references SWFLoader and loads resource/content swfs at runtime. Some of those resources have executable code, so I needed to do the following:

I've used the GUI to create a rectangle that I turned into a button symbol (SimpleButton). I then edited the button so that it had 4 different button states and a text layer on top. I then created a class definition file for this object so that I could dynamically change the label text (the text layer) when adding instances of this button to the stage.
I was able to create and link a class file (DynamicButton.as) just fine, but when I try to access the text field that I created on the button, I get the error:
"Access of possibly undefined property btnLabel through a reference with static type com.examples:DynamicButton."
when i couldn't get that to work, I decided I'd try adding the TextField directly within the class definition file, using the following code:
package com.examples
{
import flash.display.Sprite;
import flash.display.SimpleButton;
[Code].....
The problem is that I can't seem to add the TextField to the SimpleButton, as it's not a display object. So, I tried adding it to the parent of the simple button (and I figured, I'd just place it exactly above the button). But then I get a "null object reference." error.
is there a way to access GUI-created elements from w/i a class definition file? How would I add the TextField to the button using only AS3 inside of a my class definition file?

I'd like to access the stage of the main timeline from w/i a class that extends a movieclip. Basically, I have a button in the main timeline that makes a HUD appear. The HUD is an extended MovieClip class. When people click on a button in the HUD, I'd like to remove the object from the stage of the main MovieClip.I think your confusion may come from the fact that I am running this code from a class definition file. Clicking on a button w/i this object should remove it from the DisplayList of the MainTimeline. Here's the code from the class definition file:
package classes {
import flash.display.Stage;
import flash.display.MovieClip;[code]....
trace(e.currentTarget.parent.parent) gets me the MainTimeline, and trace(e.currentTarget.parent.parent.stage) appears to return the main stage, but I cannot use removeChild w/o getting an error that I am trying to coerce the stage to be a DisplayObject (which it ought to be).What's on the stage of the MainTimeline: A single button that, when clicked, adds an instance of the Answers class to the stage.

I need to know how to load and play a sound from within a CLASS definition file. I know the normal way of doing this, but Flash MX rejects that syntax, so there must be some special way of using sounds in a class file.
I need to know how to code for "if the score increases by any value." So, if the score goes from 0 to 1, the sound plays ONCE. If it increases from 1 to 2, the sound plays ONCE again.
