I have learned that there is a class called Function which is used as a blueprint for all as3 functions. Is there a way to override the call() function within the function class so that a trace can be made when any/every function is called?
View 2 RepliesI have two child classes ClassA and ClassB both inherit the same base class.
I also have a function that has a parameter which could be an instance of either child classes.
function Test(instance):void //instance is either a ClassA or ClassB instance
{
instance.DoSomething();
}
However, when I run the test, it's always the BaseClass.DoSomething() get called. How can I use the same function (DoSomething()), but call child class function instead of the base class one?
Is it possible to externally override a public function of a class (as opposed to override via inheritance)?
For example:
Code:
Class Foo {public function doFoo():void {trace ("Foo");
}
}
Such that:

I know this is possible in JavaScript and ECMAScript, but the compiler won't let me get away with this kind of mischief in ActionScript, from what I've seen: It barfs up a 1168 Illegal Assignment error as soon as I attempt to assign a new function to doFoo.
I'm thinking specifically in terms of a "hot fix" solution where you deploy a small swf that replaces a specific chunk of code in a larger application, without the need to recompile/deploy the full application (or even see the sourcecode for that matter, just know the API).
i know its easy to override a function of a parent class, but I need to be able to override a function for a class on movieclip.. see highlighted code.

override a custom class method with a function expression? For instance, if I want to change the destination of a button on the fly, I could theoretically type:
Code:
var new_destination:Function = function(evt:Event):void{ go_to_new_place();};
myButtonClass.mouse_clicked = new_destination;
but unfortunately that generates an error because the class method "mouse_clicked" is already defined in my class (with the eventListener tied to it). I tried using the "override" keyword in the Function Expression but that didn't work either.
This is for a playbook app. I have two classes:

This is essentially what I'm trying to do. What's the best way to achieve this in actionscript?
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):

is there a way to extend a function, or override it, without having to rewrite the whole function. e.g would it be possible to add a simple trace statement at the beginning/end of the addChild() function. im looking for something similar to super() in constructor. just as i dont have to rewrite the whole constructor of the class that i extend, but i can add my own code, then call super(). ive read something about prototypes and that they could be possible solutions.

I trying here to avoid having to bind resources to all my components labels ( ie a button) and find a way to have this automated.
Problem: It corrupts the layout in design mode to bind directly in the mxml label="{resourceManager.getString('myResources', 'submit')}" and makes the design view useless. but when declaring bindings elsewhere, in actionScript or via a bind tag, it is counter productive and prone to many errors and miss.
Proposition: I would like to create my own button that automatically invoke resources to localize a button label. So the author puts "Submit" in the mxml description of my button, and when running it would take the value of the label ie "submit" and use resourceManager.getString('myResources', 'submit').
but I can't find the way to override the set label function, Is it possible if yes how? else how can I go about it?
Maybe I am missing an essential process here that would make the use of resources more elegant, as well as how to override such thing as a button's label.

View 2 RepliesThe current implementation of the Flash Player ApplicationDomain with regards to override class definition seems like a giant security flaw to me.A parent SWF has complete control over what child SWF they want to load and add to its ApplicationDomain. It stands to reason that if the parent trust the child SWF enough to load the file, it should also trust the class definition defined by the child SWF and use those definitions.
In contrast, a child SWF has no control over where it is being loaded into, or if it want to be loaded into another SWF at all. Therefore, there is no reason for the child SWF to trust the class definitions defined by the parent SWF.I recommend changing the current implementation of the ApplicationDomain and allowing a child SWF to override any conflicting class definition in the parent's ApplicationDomain.

View 1 RepliesI'm having a total brain fart right now because I haven't dealt with AS2 library linkage classes in a while. I want to be able to let a designer assign an object in the library to a specific class and have that class listen for changed _x and _y values.I have the class made up that extends MovieClip:
Code:
class CoordinateMonitor extends MovieClip {
public function CoordinateMonitor () {}
}
But I draw a blank now on how I'm to monitor _x and _y values for the clip. I'm pretty sure I remember it being possible to do this and declaring an overriding function ("public function set _x(val:Number) { super._x = val; }") does not work as intended.
I'm trying to create a simple game where you can click on shapes in a toolbar and then drop them on the screen.There are three shapes, so I want the user to be able to select different shapes and such.I've written the code thus far like this:

View 2 RepliesIs there anyway that I can override a rollOut function if an action is performed?
I have three mouse events:
a ROLL_OVER
a ROLL_OUT
a CLICK
Once the CLICK has taken place I want the movie clip to stop on the last frame. But because I have a ROLL_OUT Event it wants to continue to go back to that event when I roll out of the movie clip.
do I need an "if" statement here to override the rollOut function when I click?

To delay events along my timeline. That code works fine. My problem is that is that I also want the user to be able to pause the movie at any time.

How can I override this wait function with a pause button?

View 0 RepliesIs it possible to override/replace a method of a class in AS3? When I say "replace", I don't mean subclass it and override it. I mean I literally want to replace the existing method with my own. For instance, AS3 has the built-in HTMLLoader class which has a load method. I want to say, in essence:
HTMLLoader.load = function() { trace("Overridden"); };
Therefore, when *anybody* makes a new HTMLLoader object and calls the load method, it will call my method instead.
I've tried a couple things, and so far I've gotten this far:
HTMLLoader.prototype.load = function() { trace("Overridden") };
And I compile it with -as3=false -es=true -strict=false. The problem is it doesn't override the already-existing load method. It looks in the class first before looking in the prototype, thus making it not work. There must be a way. Even if I can't override it, can I proxy it like a decorator in Python or a macro in LISP? (So mine gets called then it gets called.)
if I want to add something to the implementation of
public static function createPopUp(parent:DisplayObject,
className:Class,
modal:Boolean = false,

do I have to put all the arguments in my function declaration or does it pick them up implicitly?
I'm trying to override dispatchEvent(), with no success in the Flash IDE. Reviewing Adobe docs on the method, it should simply be:
override function name()
As demonstrated by Grant Skinner, this is commonly and easily performed:
override public function dispatchEvent(evt:Event):Boolean {
// code here
}
And while a thorough google search will repeat this syntax successfully used in Class files, doing so inside timeline code, natively in the Flash IDE is proving impossible. The first issue being that the use of public throws the error 1114: The public attribute can only be used inside a package.That was obvious, however upon removing that, running the following (on the first frame of a new .fla file):
override function dispatchEvent(evt:Event):Boolean {
trace(evt.type);
return super.dispatchEvent(evt);[code]..........
results in this error: 1024: Overriding a function that is not marked for override.
Documentation on this error implies that I failed to prefix the identically named function with the override statement, but obviously that's a fallacy, and I'm left flabbergasted as to what the solution may be.
To be clear, we know a class file will work, but that's an irrelavant issue. How do we get override function dispatchEvent() working in timeline code?
