ActionScript 3.0 :: Determine Precise Object Class Type?
Apr 21, 2011This is probably a silly question buy how do I find out if an Actionscript Object is just an Object ,but NOT any subclass IE String bool etc?[code]...

View 1 RepliesI have two type definitions (references of type Class) in ActionScript 3 and I need to figure out if one is a base type (class or interface) of the other.I had hoped something like the following would work, but alas it did not:
var isBaseClass:Boolean = MouseEvent is Event;
It is understandable why it doesn't, but it would still be nice. I can't use describeType either, since for objects of type Class it doesn't actually return the correct inheritance chain but rather just return the types Class and Object, which doesn't help at all. I can use getQualifiedSuperClassName in a loop until either there are no more super classes or there is a match, but it's less than ideal and doesn't work for type checking against interfaces.
i have a mc with a slideshow nested on the main timeline and two buttons with a simple code to pause and resume:
ActionScript Code:
pause_btn.addEventListener(MouseEvent.CLICK, onClickPause)
function onClickPause(event:MouseEvent){
[code]......
I have a custom class say class A :
class A
{
public testA:int;
public testB:int;
}
Now, I have a object say Object C , the object has the exact same names of variables and everything as the class.
can I cast that object into class or vice versa. Instead of set/get of individual variables.
I'm trying to do something like this:
ActionScript Code:
stage.addEventListener( MouseEvent.MOUSE_DOWN, mouseIsDown );
function mouseIsDown( e:MouseEvent ):void

I am trying to find an object in the display list. All that is known, is the name of the class. I recursively iterate through every child in the display list to find my object's instance, and unfortunately everything was instantiated at runtime and was given a generic instance name. This videoplayer has around 300 children(ugh), and through trial and error I found my instance I need to get a hold of, instance60. Now it would be fine by using just the instance name, but the thought of it being called a different instance name would send this program into insanity.

and its structure:
obj.name = "John";

What happens when an object which has a function currently being executed has all its references removed?I want to have a dialog box type object held in an array by the main class for my program, and when the dialog needs to be closed, I want it to be removed from the array during that close-screen function. My question is, assuming the dialog box object is in all other ways eligible for garbage collection, what happens to the code it's supposed to be executing?
Edit for clarification:The array is a layer of visual elements in my program, of which the dialog box is one. The idea is that the "OK" button (or whatever) that closes the box will also remove it from the array of objects being displayed at the same time.

So for instance, I've got three .as files called 'Helicopter.as, Game.as, Blue.as'
and I also have a .fla file called Helicopter.fla (These files are all suppose to link together, to make the helicopter game) . In the Game.as file, I have the following;
[Code]....
Flash doesn't recognise the original Helicopter symbol (in the Helicopter.fla file, because I deleted it). But I want the system to detect the 'circle' drawn using API (In the Helicopter.as file). And I have no idea how to how to name the API drawn circle 'Helicopter', thus I'm getting an error. So how do I name the API circle to 'Helicopter', so the Game.as file recognises it.
I keep getting the following error msg below I would be very happy if some knows the solution to this: Error Msg: 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.events:Event Object A dispatches Event as:

Is there any way to determine a file type from a url when the file extension is not a reliable indicator? Since there are different APIs for playing video, audio, or displaying images, you need to know the filetype beforehand.

i'd like to throw an argument error if a particular function doesn't work without a passed value that also happens to be a public constant of the class containing the function.is there anyway to determine if a class owns a public constant instead of having to iterate thru all of them? something like this:
public static const HALIFAX:String = "halifax";
public static const MONTREAL:String = "montreal";
public static const TORONTO:String = "toronto";[code]....
currently, for this functionality i have to write the city setter function like this:
public function set city(value:String):void
{
if (value != HALIFAX && value != MONTREAL && value != TORONTO)[code].....
since the MXMLC compiler doesn't support mixed access modifiers for setters/getters, i would like to know whether a public setter function is being called from inside or outside of the setter's class. this approach should allow me to maintain a public property but with more security, something like public/private hybrid access. is it possible to use arguments' callee property, or perhaps something else, to determine whether the setter was set internally from the setter's class or if it was set externally?

how to determine if there's a dragged object. Is there a way to do this?
I know if you start another drag on the other object it will stop the current dragged object. Maybe there's a public function that will query about this?
In Java, what is the best way to determine the size of an object?
In Actionscript I can usually just do:
var myVar:uint = 5;
getSize(myVar)
//outputs 4 bytes
How do I do this in Java?
i have a class called "Ball" that extends "AllSprites" which is a class that extends "Sprite". there is an addChild within the "Ball" class that adds a Sprite to the stage. when i run it like this, it successfully adds the object to the stage.
in my Main class i have
Code:
var ballOne:Ball = new Ball();
i am trying to get the x and y value of ballOne from within my Main class but if i try to do
Code:
trace(ballOne.x);
i get an error:
1119: Access of possibly undefined property x through a reference with static type Ball.
how do i tell my code that the ballOne is a Sprite so i can get the x and y values?
also not working:
Code:
trace(Sprite(ballOne.x));
I created an flv video player using Flash Builder 4. This "BasicVideoPlayer" project is compiled into a SWC that will be eventually be used to create other video players that extend the functionality. One of the features is a view that appears when the video has finished playing that displays a "Play Again" button. This "Play Again" view has its own class, "BasicPlayAgain", that accepts a graphic asset that is exported from a .fla file that contains all of the graphic/UI assets.
In my new project, "EnhancedVideoPlayer", I'm using the BasicVideoPlayer SWC as a library to create a new video player that will add more functionality to the "Play Again" view; specifically it will add more buttons to that view.The EnhancedVideoPlayer uses a default class that extends the BasicVideoPlayer class. The BasicVideoPlayer class has a member called "playAgainScreen" whose type is BasicPlayAgain. The EnhancedVideoPlayer needs to override the playAgain member and recast it as EnhancedPlayAgain so it can control the new buttons properly.
I realize this is kind of an odd issue, but I am wondering if there's any way to get Flash to allow me to access a class's static functions using a class variable that points to the class. Example:I create a class called FooClass that has a static function named fooI then create a variable of type Class that points to it
Code:
var class:Class = Class(getDefinitionByName("FooClass"));
However, when I try to call foo() using the variable, it errors saying the function

I got something like this:
var myClass:myClass = new myClass;
addChild(myClass.showLabel);
Then, inside this class there's this code:

I am working on a Flex Front End at the moment, and have been using the Parsley framework for passing messages/events around.
I was wondering if there is a simple way for a function (in this case, an event's constructor) to obtain a reference to the object which called it?
This is to ensure that a certain event that I am defining can only be dispatched by one specified class. My thinking is to check the caller of the constructor somehow, and throw an error if it is not of the correct type.
For this example, I will use 2 classes, Entity and CSpawner. CSpawner is a children of Entity.I want to perform the following condition:if((new CSpawner()) is Entity)It works just like intended.But I want to do this test, without creating a new CSpawner object, something like this:if(CSpawner is Entity)But it doesn't work, because CSpawner is a Class.How do I perform that kind of conditional without creating a new CSpawner object?
