ActionScript 2.0 :: Class Constructors - Xml File To Build Up An Interface
Feb 11, 2008
Not sure if this is possible but it has been annoying me for the least few days. Basically im aware i can do this to instantiate a class
[Code]...
However, if i pass in a string for the SOME_VARIABLE , is there anyway i can get the above to work? If i pass a string in i either get no error, or the fact that the datatype is incorrect. Im using an xml file to build up an interface. but the value of SOME_VARIABLE is passed in from the xml file as a string. I want to be able to detrmine which class to create from this string.
currently i am setting up a class to handle a movie clip, tweening from one spot to another. I want to be able create an instance of this class, pass in 2 arrays (an array of x pos's, and an array of y pos's), and also pass in the mc to be attached and thecontainer to attach it to.I currently have this
Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement; var m:IMovement = new ClassReference as IMovement; trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class; var m:IMovement = new ClassReference() as IMovement; and this doesn't seem to work...but the following var m:IMovement = new OuterSpaceMovement();
I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite; public class MySprite extends Sprite {[ code]...........
but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.
i am working on a project where i have some common code which i import in different movie clips and different files the code is in actionscript 2 in an external .as file. this is not a class its just a bucnh of functions and temporary variables.Problem is when i use the check syntax button or auto format button i get the following error."ActionScript 2.0 class scripts may only define class or interface constructs."this used to work fine in flash 8 but it always gives this error since i started using flash 9.the code works fine too. its just that my auto format button and the check syntax doesn't work.
function someFunction(classParam:Class):Boolean { // how to know if classParam implements some interface? } i.e. Comparing classParam with IEventDispatcher interface
[Code]...
There is a way that DOES NOT USE describeType or creates a new operator?
recently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)
i have incuded an AS file in my fla. But is gives an error ball.as: Line 73: ActionScript 2.0 class scripts may only define class or interface constructs.
I have one .fla file and two .as files. I think my problem is I don't know how to set the path for the action scripts. All three files are in the same directory
The files: dtd.fla TransformItem.as TransformManager.as
The error: The class or interface 'gs.TransformManager' could not be loaded.
dtd.fla code appears to have an appropriate import: import gs.TransformManager; var manager_obj = new TransformManager([], onTransformEvent, true, false, false, false, false, true, true);
TransformManager.as code appears to have an appropriate import: import gs.TransformItem;
I've been rewriting a code from AS3, to AS2. I got stuck when i tried to make a constructor have default parameters. The default parameters are determined by variables.In AS3, it would simply be:
I'm doing a simple link code. I've tried many diferrent ways to do this but this error keeps comming up saying The class or interface could not be loaded...
home_btn.addEventListener(MouseEvent.CLICK, gotoURL); function gotoURL(event:MouseEvent):Void{ navigateToURL(new URLRequest("my site"));}
This is the most recent method I've tried in doing this. I've tried changing the publishing settings of the document to and from Action Script 3.0- using an import command. But thats too complicated. Attachments: Flashfla.fla.zip (767.8 K)
Can I implement more than one interface to the same class?One option is to make interface A extend interface B and than have my class inplementing interface A. Is there any other way that I can implement two or more interfaces directly to the same class?
Quick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ?
I have created the following classes for sharing images. They implement an interface, but I need a way of switching between them with user interaction. I've done it the following way:As you can see, service 1 and service 2 implement iSharingServices, and inherit from PolimorphSharing.PolimorphSharing is simply and an abstract class that implements the methods I want public from Service 1 and Service 2. Those methods will then be overridden on the Service 1 and Service 2. Because I need a way to switch the service in runtime, I've created a gateway class that inherits from PolimorphSharing. I can then call it the following way:
private var sharingService:PolimorphSharing = new SharingServicesGW('svc1').createService();
This all works flawlessly, and I can now switch between services with no problem whatsoever. However, I feel there's something wrong about it, so I would like to ask you guys for some advice on how to better implement this.
UPDATE: Just adding some more insight to this. Basically the idea here is for my client to be able to upload images with various different public sharing services such as imageshack, imgur etc. I want my client to be able to select the service in which the image is to be published to (hence the "switching between them with user interaction" bit of the question.
The method that does the uploading bit, is requestShareImage(), processResults() simply turns whatever gets returned to a unique format, so my client can read off it always the same way. getObject() is my accessor, and onIOError will handle exceptions with any of the public API's
I got the error message below when I try to put them onto my own flash file, The source codes work well by themselves.The class or interface 'URLLoader' could not be loaded.The class or interface 'URLRequest' could not be loaded.
It's not clear to me, where I have to define Classes and Constructor methods. In AS2 it was possible, to define a class "light" by defining a constructor method. In AS3, I read, a class can only be defined in an external AS-file. Is it still possible to use the constructor method inside the Flash-File or do I have to source out all my constructor methods and implement them into real classes into an external AS-File?
I am getting an error with RegExp class at my flash document. I am using an Action Script 2.0 at my document. Is RegExp class is not supported in AS1/AS2 ?
My code is as follows function validateEmailAddress(emailString:String):Boolean { var myRegEx:RegExp = /(w|[_.-])+@((w|-)+.)+w{2,4}+/; var myResult:Object = myRegEx.exec(emailString); if(myResult == null) {return false;}return true; } if(validateEmailAddress(email) == false) { contacterror = "Error ! Please Enter Valid Email Address";}
If RegExp not supported in ActionScript 2.0 then how to validate email address at ActionScript 2.0 ?
I am creating objects for a game, they are all sprites. but I also want them to implement an interface. Is it possible to do both ? If not, how can i have an object have the capabilities of a sprite and also have it implement an interface. I am wanting to create another class that checks all my objects to see what datatype they are and evaluate them accordingly
I have an older site that is coded in AS2(I can't get it to AS3 sorry) I found this script online that allows for mouse scrolling. It is in AS3 and I can't figure out what Event replaced in AS2. I'm sure there are much better AS programmers than me that could tell me off the bat. I'm just trying to get this converted to AS2.
var verticalCenter:Number = stage.stageHeight / 2; var limit:Number = stage.stageHeight - content_mc.height; var speed:Number = 0.1;
whats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?
I am currently doing this gallery with prev and next button.But i got this error message.."The class or interface of MouseEvent could not be loaded." [code]
Why doesn't the Flex framework's mxml language support a constructor for components or accept constructor arguments for components? It's as far as I know not possible to declare an ActionScript object in mxml if it takes constructor arguments. I'm curious about the reason. Is it a design choice by Adobe or related to how declarative languages work? For example, why not allow:
I think I understand how to make a interface but the problem is im unsure as to how to add it to my existing code! To make a interface (as far as i know) You can create classes such as mainScreen, intructions and so on. Ok i get that, make the classes then add ther buttons from the library i these classes. But i followed a tutorial bu Emmanuel Feronto, and adapted that to the needs of my game.
So im unsure as how to add these 'Screens' to my current class, the I currently only have 1 class, Main which currently has 300 lines of code, and i dont know how to break it up into smaller classes. Thats the problem i think, The main is quite large, normally i have heard people keep this clear... But then say i made a bland main, and added the screens into that then how do i make the main that makes the game play on the play button?
Not sure if this is possible but I would like to reflect a swf or swc file selected by the user at runtime to find any classes that implement a certain interface. Can this be done or do you actually need a reference to the class you want to reflect using describeType();
In ActionScript 3.0, there are a few ways to check a class's extension. For example, if I want to know of a custom class extends Sprite I could use the is operator: trace(MyClass is Sprite); Or I could use flash.utils.getQualifiedSuperclassName: trace(getQualifiedSuperclassName(MyClass));
I would like to accept a class as an argument and check to see if the passed class implements an certain interface. Is there an equally simple or common way to check if my custom class adheres to an interface? Perhaps something like: trace(MyClass implements IMyInterface);
The class or interface 'it.sephiroth.XML2Object' could not be loaded?? I did the installation of extension and adobe extension manager confirmed installation to be successful and yet I cant
