Actionscript 3 :: Declare A Variable In My Base Class?
Mar 22, 2012In AS3, is there a way to declare a variable in my base class and be able to access it in all other classes in the program?

f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".
I am trying to do is declare a variable in PHP and pass that variable to my flash file. Right now i am simply trying to do 1 easy variable, more will happen in the future but i need to figure this out first.I have used other forums and they say try this and that, but nothing i do seems to work. here is my code.

Which is the best way to decalre variable?
Inside a class or Inside a constructor
I'm trying to get a value from a function which is a URLLoader COMPLETE event but even with declaring variables outside of the function will not allow me to get the value out. I'm stuck.It seems that the Asynchronous nature of Flash makes it impossible to get a value out: e.g. this works:
// Initialise a URLLoader to get XML data from XML file
var myFPBLoader:URLLoader = new URLLoader();
myFPBLoader.load(new URLRequest("flightPlannerBoard.xml"));

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).
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 RepliesI'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:
[Bindable]
public class Base
{
public var msg:String;
[Code]......
where msg is some textInput field. I am getting a message from the compiler that....
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;
[Code]....
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).
