Actionscript 3 :: Calling Static Functions That Don't Exist
Nov 16, 2010
I'd like to have a class that will resolve calls to static functions that don't exist.If you have an object that subclasses the Proxy class, you can override the callProperty() method to catch calls to functions, as properties of that object, that don't exist.How can this be done with static function calls in a class? It cannot be done by making the overridden callProperty() method static. Is there another way?

Ok, so I have a bit of a mess here (Which I'm probably not doing right anyway, which could be my problem...). I have a document class, I'll call it as Body.as, that creates an object from another class known as Headgear.as. There are also other objects created from other classes, or will be in the future. Now, amoung all this, Headgear.as and all of the other classes Body.as will use to make objects require the use of dragging functions (starting and stopping dragging). On stopping drags, position checks are then made to compare a particular hidden movieclip with the dragged MC.
To try and save myself some hassle (from making the same functions over and over to ensuring that when the objects are created I don't need to send a complete crapload of variables just to ensure the position checking function would work), I had the functions for the event listeners (Which are set-up on the draggable MCs in Headgear.as) just direct to functions in Body.as

I've seen a lot of places talking about the technique, and citing codes like:
factorial = function(n) {
factorial(n-1);
}
I don't understand the concept of calling a function within itself. What precisely does this accomplish, and how is it legal? Shouldn't the function definition fail because while its being defined its calling a function that does not yet exist.

I have a simple flash socket that I use to connect to IRC servers. It has an open, close, and send method made available to JS through ExternalInterface, for opening connections, closing connections, and sending messages respectively. The socket calls IRC.io.receive in JS whenever it gets a message, which is parsed by JS into something useful.Unfortunately, whenever any of the flash methods are called from JS, they return a "__ is not a function" error.Here's the (watered down) AS, where IRC is the document class:
public class IRC extends MovieClip {
public static function open(url:String, port:int) {/* code */}
public static function close(port:int) {/* code */}
public static function send(port:int, message:String) {/* code */}
[code]....
Any call to any of the functions registered with ExternalInterface throws a "function does not exist" exception.

Basically, what I mean is I i have few layers of classes, that calls and change something on the 1st(root) class. In between the process I have to use static var and static function.But when I want to run a function which does not change any variables, for example:otoAndStop(someFrames), I need to make the function a static function too or else there would be error
Code:
1061: Call to a possibly undefined method checkStatus through a reference with static type Class.

I am using get/set functions to make variables that are (or appear to be) read only. I can get it to work with instance variables, but not static variables. I found this, which seems to indicate that it's possible to use get/set functions on static properties, but the compiler keeps telling me I have duplicate function declarations. This is essentially what I'm using:
package {
public class Foo {
protected static var bar:int = 0;
public static function get bar():int {return bar;}
}
}

It seems that Actionscript doesnt support defining static functions in interfaces. Whats the reasoning behind this?I think it would be useful to have that ability but I'm sure there must be a reason why its not there.

I have 3 external .as files...
Game.as
Checker.as
CheckerP2.as
In Checker.as I have the following function...
static function checkPossibleMoves(){
...
}
I'm able to call and execute this function from Games.as using the following code...
Checker.checkPossibleMoves()
But whenever I use the same function call in CheckerP2 the function does not execute?

I have never encountered this problem before.
I have a support class called ICSNAArrays.
It contains only static functions.
In my main class file I have imported it and then when I try to call one of the functions I get a compiler error that says there is no method with the name 'ICSNAArrays' I don't understand this. There are no errors importing it. All of the spelling is correct I am 100% sure on that. [url]...

I'm working with an application which was originally designed to make heavy use of static-variables and functions to impose singleton-style access to objects. I've been utilizing Parsley to break apart some of the coupling in this project, and I'd like to start chiseling away at the use of static functions. I will explain the basic architecture first, and then I'll ask my questions. Within this application exists a static utility which sends/receives HTTP requests. When a component wishes to request data via HTTP, it invokes a static function in this class: Utility.fetchUrl(url, parameters, successHandler, errorHandler); This function calls another static function in a tracking component which monitors how long requests take, how many are sent, etc. The invocation looks very similar in the utility class:

I have a Flash application that creates a sort of powerpoint presentation. All the 'slides' are stored in an XML files which is read and processed.
I'm trying to build the presentation using this XML file. At the moment, my main class has it's initial function main and a static function processXML main initiates my database class with a function called initDB. One of my issues is that initDB forgoes processing because it's dependant on an event listener. On completion of loading the XML files, the event listener initiates my static function on my main to create objects from this file.
The issue is that because the event listener continues the processing (after an indeterminate amount of time), the functions are no longer controlled by the main class.

Let's say I would want to use the frameScript method to add some stop and play methods to some frames.
Normally I would declare the stop function:
[Code].....
My question is, how can I create the same $FUN_FrameStop as a static function?
Static functions do not allow the use of this since static members are bound to a class and are not inherited by that class' instances.
So, is there a way to create a function similar to $FUN_FrameStop, but static?

To rephrase my question: if you have a class with a bunch of static methods and you use one of them in your code, does the whole class get compiled with your movie? I suspect that it would be and, if that's the case, wouldn't it be better (from a file-size perspective) to use packaged functions instead?

If all I have is an instance of an object, can I call a static method of its class? For fun, let's say I don't know what the name of the class is, only the name of the static method.

I'm creating a utility function for debugging/logs, which I access by importing the class and calling
new Log(params);
Alternatively I change the function to a static, and rename it to It,
then I can call it by Log.It(params)
I'm wondering if it possible to set it up so I can simply call Log(params) similar to the trace command?
function:
package
{
public class Log
{

My method has been passed a class instance, but it was typed through an interface so I'm not 100% sure what class it is. I'd like to attempt call a static method on that instance's Class.. is there an easy way to do this without being forced to pass the class along as well?
Something like this:
ActionScript Code:
public function foo(myBarInstance:IBar):void {

if someone can shed some light to this matter... i'm pretty new (somewhat) w/ AS let's say, i got an .swf (voets enahnced mp3-player) @ [URL] --which works perfectly at the moment. i then referrenced this .swf in [URL] --which doesn't work prolly because the .swf is calling the XML (i.e. "onlineplaylist.xml") relative to its whereabout, which is /test08. the question is, is there any way around this problem, so that if i put all .SWFs in a certain location (server/directory/what-have-you...), and referrence it from another server &/or directory (like above), it would work?

If I have a function and I want to call a variable from another function (only 1variable), how do I do it? I know in the olden days you could set the variable to local or global, but that does not seem to work anymore. There is only 1 variable I need access to, but all the tutorials I have come across talk about making classes for multiple variables.
e.g. function2();
{
variable_b = variable_a;
}

I can't get it but, i'm coding in as3 and i can't target a function from a swf file loaded in the DisplayObject loader in any way. I don't want to create a class to make this function works. It's a simple function, made to change a picture every time the user navigates on another swf. Well. The point is, why in the name of God, the as3 cannot target another swf? How can i do it?
