ActionScript 3.0 :: Accessing Static Variables Using The Class Name Itself
Jun 18, 2009Say I have a class called Ball (movieclip) and I create a number of instances of it. There is a static variable, say, ballArray and need to access that from a different class, say, Bat. How do I go through with it? Can I access that using the class name itself (Ball.ballArray like in Java)?
View 1 RepliesActionScript 3.0 :: Imported Class Reference And Static Variables
Jun 8, 2010I'm trying to make methods available like so:
ActionScript Code:
MyClass.myFunc();
Instead of
ActionScript Code:
var myVar:MyClass = new MyClass();
myVar.myFunc();
I know that to do so I need to declare the functions/variables/constants as static:
ActionScript Code:
package MyPackage {
public class MyClass extends Object {
public static function myFunc():void {
} public function MyClass() {
[Code] .....
When I try to access the static function through the full reference (i.e trace(MyPackage.MyClass.myFunc);), it works, while trace(MyClass.myFunc); returns undefined. This contradicts what I've read in tutorials and posts on the Internet. They all use the short syntax, not the full path.

ActionScript 3.0 :: Static Class Needs A Non-static Function
Nov 22, 2009Alright, so I have a class that is linked (via the linkage panel) to a scrollbox class. I'll paste the class here:[code]Ignoring the formatting, the commented out functions are the ones causing the issue. Adobe says that it's a static class and I can't use non-static functions. The way I wanted to use it was:
1. Call the page button generating function above.
2. In the main code in my program is this line:scrollbox.setClickFunction(historyContent.generate Page);So when the buttons that are supposed to be generated are clicked, the scrollbox class can call the History pages generatePage function and pass it which page to show. (I did this because there was a lot of text and a limit on how much would display, so small chunks sounded logical).
3. In the onClick function (which I haven't finished yet because the rest wont work), when you click one of the buttons it calls the set function. Its that simple.

Actionscript 3 :: Big Performance Difference Between Using Class With Static Functions Vs Instantiated Class?
Mar 22, 2012I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.

Actionscript 3 :: Prototypes - Are They Just Static Variables?
Sep 13, 2011A reference to the prototype object of a class or function object. The prototype property is automatically created and attached to any class or function object that you create.This property is static in that it
is specific to the class or function that you create. For example, if you create a class, the value of the prototype property is shared by all instances of the class and is accessible only as a class property.Instances of your class cannot directly access the prototype property. A class's prototype object is a special instance of that class that provides a mechanism for sharing state across all instances of a class. At run time, when a property is not found on a class instance, the delegate, which is the class prototype object, is checked for that property. If the prototype object does not contain the property, the
process continues with the prototype object's delegate checking in consecutively higher levels in the hierarchy until Flash Player or the Adobe Integrated Runtime finds the property.
Note: In ActionScript 3.0, prototype inheritance is not the primary mechanism for inheritance. Class inheritance, which drives the inheritance of fixed properties in class definitions, is the primary inheritance mechanism in ActionScript 3.0.
from this I get the impression that prototypes are just static variables.. am I right?
ActionScript 2.0 :: Proper Use Of Static Variables
Dec 19, 2004I have created a class to define my main navigation buttons. I would like to handle which button is clicked/pressed as simply and elegantly as possible, and I figured the best way would be to add a static variable to the class that keeps track of the current button pressed. Here's some quick pseudo-code. Code: class MainButton ext MC static var currentButton:MainButton public var sectionToLoad:String public static function getCurrentButton() public function getSection() button.onPress = currentButton = this // other button actions. // then i can check for what the currently clicked button // is and now access its variables. MainButton.getCurrentButton().getSection() etc. etc. etc. I am curious if this is a "proper" way to go about tracking the buttons. I find it is pretty elegant, but i'd rather make sure that this is a good practice of using static class variables. Also, it looks to me that all custom class definitions become a _global object?

View 2 RepliesActionScript 3.0 :: Is It Good Practice To Use Static Variables?
Feb 5, 2010I've always used this way to refer to variables on my document class
Code:
MovieClip(root).variablename
But that complicates things because I would need to extend my class as a displayObject and then add it to the displaylist to be able to use "MovieClip(root)" to access the variables in my document class.. as long as variables in my document class are set out as public variables..
I didn't realise you could refer to variables on the document class by just using something like:
Code:
documentclassname.variablename
With the the variable on the document class as "public static var". This solves a lot of problems.. as now I do not need to keep adding objects to the displaylist to get access to the document class variables..
Now.. My question is..Since I want to access most of my variables on my document class.. I would need to set them all to "public static var".. Would setting 100 or so variables to "public static var".. have any disadvantages? Like performance issues... Or anything else which may make it not be as efficent if I were to keep them simply as "public var" and use "MovieClip(root).variable" to access them?

View 1 RepliesFlex :: Debugging Or Watching Static Variables Within Flash Builder 4
Dec 16, 2010When I set a breakpoint and debug my application, Flash Builder 4 is not displaying static variables within the variables window. I'm using flash builder 4 to execute flex unit tests on one of my AS3 classes. I set a static variable within the [Before] function, which is accessed in each of the tests. I've set a breakpoint within one of the tests to see why it is failing, but I notice that static variables don't appear when I expand the 'this' object within the variables window. (In this case my static variable is the only variable associated with the class, so the only object in the variables window is the "this" object). How to make static variables appear in the variables window?
View 2 RepliesActionScript 3.0 :: Global Variables: Singleton Versus Static Vars?
May 29, 2009pros and cons of either using a Singleton that enforces only one instantiation of itself, versus creating one common class with static vars which can be accessed by all other classes that import it?
In my testing, importing but never instantiating works fine. I can even change the value of one of the variables and then have another class see that changed value later on in the program.
If I *know* I will never actually create an instance of my Global class using the New command (but will instead just reference the variables using the class's name), then why should I need to make it a strict Singleton?

Jun 28, 2010Hi there, i am hoping for some advice on structure/optimisation from some of you experts . I am working on a portfolio system that is modular, each module works in a self contained way and does not require the other modules to function, though they can be 'linked' by having them all reference the same PortfolioData() class.
im happy with how it is working, but i feel there could be a better way to share the datasource between all classes rather than duplicating it and storing a copy in each class.

ActionScript 3.0 :: Static Class Constants Be Too Slow ?
Feb 23, 2011I am working on a Flash site template for which I am implementing the possibility for the users to change the theme dynamically while the site is opened.Basically, the site will have a few themes available and when the user selects a new theme, all of the site objects will change their properties (colors, alpha, fonts, etc) to fit the new theme.
And my questions is what is the best approach to sending the theme information to all of the objects in the site.I was thinking of making a static class called "Theme" and when the objects need a property, they will call a static getter of the Theme class that will return the appropriate property value for the object.But, from my understanding, static properties are quite slow and seeing that I may need quite a lot of them, maybe more that 100 for the whole site, will this approach be too slow ?
