ActionScript 2.0 :: Custom Class Instance Doesn't Recognize Own Constructor
Aug 18, 2011
I'm having a problem with customized Actionscript objects not recognizing thier own constructor. This is the pertinant part of my script:
ActionScript Code:
//File: Line.as
class Line extends Object{
public function Line(args){
[Code].....
Clearly, the variable "testLine", is one of my custom "Line" objects. Clearly, it has been made with the "Line" constructor. So why won't flash acknowledge this?
Is it possible to create an instance of a class without triggering the class' constructor?[code]In the case above, say I wanted to play around with a Foo instance, but I really don't want my global.foobarCount going up, nor do i want to pass in any value at all for bar.This could be useful for introspection where you want to learn more about or pass a particular class object but don't want to provide required arguments or trigger anything that the constructor may do.Is this at all possible? (Obviously, new Foo() just doesn't cut it here, since it would throw and arguments error, nor does just using Foo, since that's a reference to the class itself).
For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)
I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.
Can I define a custom class to be an AsBroadcaster in the classes constructor?
Code:
class myClass{ function myClass(){ AsBroadcaster.initialize(this); } }
And if so will that give me the ability to addListeners to an instance of that class?
The reason I want this approach is because I want to broadcast events from inside one of the custom classes methods and I want a textField on the stage to be listening for that broadcast message.
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying [RPC Fault faultString="Unable to create a new instance of type 'some class'." faultCode="Server.ResourceUnavailable" faultDetail="Types cannot be instantiated without a public, no arguments constructor."] How to import class having overloaded methods using blazeds
I have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.
deleting class instances. say i have a bullet class. say the bullet class checks when the bullet hits an enemy. how to delete the bullet when it hits the enemy.
I have created some (TextInput, ComboBox, CheckBox) Component instances (created as a public objects) in a Document class and added them to the stage.
Now I have created a custom class for a movieclip in library and instantiated it in the document class (also a public instance).
I need to access the component instances in the custom class. How to do this ?
Also, Is it a good practice to use ENTER_FRAME event frequently ? because if I can't access the above components instances in the custom class then I will be left with no choice but to use ENTER_FRAME event in the document class every time I need to change some value in the components...
I am trying to replace a MovieClip with an instance of my custom class CustomMovieClip. What I want to do is make all references to MovieClip refer to CustomMovieClip, something like the following:
Code: var _mc:MovieClip = new MovieClip(); addChild(_mc); _cmc:CustomMovieClip = new CustomMovieClip(); replaceMc(_mc, _cmc); trace(_mc); // I want it to output '[class CustomMovieClip]'
I want this to work so any variables that hold the MovieClip should refer the the CustomMovieClip after the replacement. Is this possible?
[AS] class test extends MovieClip { private var butnPath; function test() { butnPath = this.cool_button } }
I assign this custom class to a MC containing a button with a instance name 'cool_button'.This code gives a me a compile error of 'variable cool_button not defined', what i am trying to do is reference something that is in the MC itself. The only solution i have found is to name the var the same as the instance name you are trying to reference.
I would like to make a new instance of a MovieClip within my library from code written in my keyframe. I relise that you can do this by making a class and using the codeCode:var instancename:movieclipname = new movieclipname(); and with the MovieClips class I would need to extend MovieClip and nothing else. I am unsure if you put in the name of the MovieClip or the name of the MovieClip class in the code above so feel free to correct me. But instead of doing this can I just add a MovieClip to my stage with doing this
I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid: _tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following: DataGrid(event.currentTarget).selectedItem as Rule
I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class: package com.mycompaany.arcc.business { import flash.utils.describeType; import mx.collections.ArrayCollection; [Code] .....
I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.
I am programming a web based application with Actionscript 2.0 classes for flash 8, and I want to save user data using the local shared object.As the data is potentially rather complex I would prefer to store it in an instance of a custom class that I then stick in an array property of the local shared object data property.However, when I try to do this, if I retrieve the stored object it seems to have lost all its instance methods. If I do a for in on it, I can see the private properties to which I have assigned my data, but as they are private I cannot retrieve them.how I can store an instance of a custom class in a local shared object without it being corrupted in this way?
I just installed Flash CS4 and brought ip a couple of fla's I get a box telling me I don't have some fonts on my system that I know I do have like Verdana and Ariel, etc. Is there something I should configure?
I get the error "Access of undefined property menu_bar" when menu_bar is an instance name directly on the main timeline. I'm not sure how I would call it in the other class. It also isn't exported for actionscript is that the problem?
I have it imported to my document class as:
var mouseClicks:MouseClicks = new MouseClicks(); addChild(mouseClicks);
Flash files I embed have faulty plugin detection - it does not recognize FP10 as an upgrade from FP9. This is in the knowledgebase, but it does not suggest a solution. "Some websites will ask you to install or update Flash when you already have the Flash 10 plugin installed. This is not a problem with your Mozilla browser or your Flash plugin, but with certain websites that misidentify Flash 10 as Flash 1 due to a faulty detection scheme. Contact the website and ask them to correct the problem or, on Windows, you can try the site in Internet Explorer, since the Flash ActiveX detection may work even though the plugin detection does not."
I'm new to flash and action scrip 3.0. I made a movie clip and in it two buttons. The first button is called designer_b The second button is called animator_b This is the code I made:
Do you have idea about the reason for that error and how to prevent it? N.B. The code that triggers this error is as a result for click handler. If before encountering this error change the selection on my yearsCb, everithing is fine. EDIT: I forget to specify that this error is thrown when it is a selected item in my ComboBox. It seem that after container that holds the ComboBox loses the focus, it doesn't recognize it's ComboBox child as having a selected item anyway (this problem arise only after the modal popup close.).
I'm using this AsyncHelper. I would like to create basic test case where I would like to dispatch event from the test method (by Parsley MessageDispatcher), catch this event in any other method and dispatch it back (by flex EventDispatcher).
This is my test case: package flexUnitTests { import flash.events.ErrorEvent;
how to make my package use stage.stageHeight so I can tell a ball to bounce when it reaches the bottom of the stage. I'm calling my ball to the stage from the library in a way I'm not used to and have never done so I'm assuming it has got to do with that. if you take a moment to look at it (pretty simple i've stripped out everything except for the physics that makes a ball drop and bounce) and let me know why I cant detect the stage.
I've got an app where I'm grabbing the currently highlighted text from the user in a RichEditableText block and I've noticed that when the user highlights a selection after a carriage return that selectionActivePosition and selectionAnchorPosition return values that don't count the carriage return, even though when I slice the corresponding text with the retrieved values, it does take the carriage return into account and therefore returns a value shifted one character to the left for each carriage return appearing earlier in the text.
I was asked to update some information on a certain project. The weird thing is that whenever I try to export the movie from Flash (I work with CS3 Professional), I get errors. Before even changing anything. All of them are reporting MovieClip not being recognized ("The class...... must subclass flash.display.MovieClip since it is linked to a library symbol of that type" (and a few SimpleButtons too). There is a total of 57 errors. All the classes import and extend MovieClip.
Now I'm pretty sure this doesn't have anything to do with the code itself, since this project was already published and tested working as it is. I tried adding Class paths in the preferences menu but this didn't seem to help.
I'm trying to create a five image gallery, and when I try to add the load request for the 3rd, 4th, and 5th images I get an error message that says it doesn't recognize that request: see code below:
stop();//turn on buttonMode for mc's so mouse changes to handone_mc.buttonMode=true;two_mc.buttonMode=true;three_mc.buttonMode=true;//four_mc.buttonMode=true;//five_mc.buttonMode=true;////--add button modes for 3-5 here////define
I have a button that was added to stage using addChild when the page load, the button is suppose to be removed using removeChild and redirect into its specific page using event.target.name...somehow i got this error: Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I have try replace this line, var newswf:URLRequest= new URLRequest("./swfs/"+ event.target.name +".swf"); with this, var newswf:URLRequest= new URLRequest("./swfs/about.swf"); and everything works fine, but i dont want that since I want it to load dynamically and uses less code..
my code as below:
var about:About = new About(); about.x = 300; about.y = 200;
