Here's the example: var cartesian:CartesianChart = new CartesianChart(); cartesian.width = 100; var column:ColumnChart = new ColumnChart(); column = cartesian as ColumnChart; Why does this not work? "column" ends up null. ColumnChart is a derived class of CartesianChart, so I would have thought I'd end up with a ColumnChart with a width of 100.
I'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).
I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')] public Class Base {
I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree public function HierachyTree() {[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor { private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.
I have a method which registers an event listener to each of the MovieClips in an array I have. The method is inside a class, and so is the listener function. The problem is, I'm getting an error that's says "Access of undefined property handleNavToggle", even though is declared.
I made a custom event, but was getting this runtime error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::Event@1498f491 to com.esidegallery.net.BatchLoaderEvent. and eventually found what I thought was the the answer here - [URL] I made the necessary changes, but I'm still getting the same error! It's just a batch loader that dispatches a custom event for every item that loads, with its LoaderInfo object attached. Here's the event code:
I have tried the following code to create a thumbnail preview that loops and is clickable to go to a new page with a video gallery. The video plays anbd loops, but, it does not seem to recognize the mouse click i have a trace that isn't being triggered an nothing happens. code is below.
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:
It's coming from this line of code:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == nNode.parent().@question_questionID)[0];nNode is an XML node sent as an argument to the function this is called in. The code runs,and does everything expected but the compiler sends out that warning. Do I have some formatting issue?P.S. I've tried telling it that it's XML like this:var dropTargetXML:XML = XMLTemplate.template.component.section.question.(@question_questionID == XML(nNode).parent().@question_questionID)[0];
I constantly get:Implicit coercion of a value of type Class to an unrelated type lash.display.BitmapData.var ba:ByteArray = jpg.encode(BitmapData);This is my code from where it tells me it's wrong"
ActionScript Code: var jpg:JPEGEncoder = new JPEGEncoder(); var ba:ByteArray = jpg.encode(BitmapData);
Basically plots a dot wherever you click. Getting the error 1067: Implicit coercion of a value of type Class to an unrelated type Function.

I don't understand why this script doesn't work. I am new to Action Script 3.0 and I watched this incomplete video on youtube. -- [URL] and I got the fails below.
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 was having a go at a tutorial which worked fine but then I started seeing how it would work in an external file. Object Oriented Flash. On line 27 it picks up the following error... 1046: Type was not found or was not a compile-time constant: Event. //function enterFrames(e:Event) I've tried this for myself but what are the function parameters I need to mimic the same motion of the bouncing ball?
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'm working on an accordion component and I was thinking that it'd be cool if I could write a very basic one and then set it up so that it would be possible to pass in any kind of container class and child class so long as they subclassed a particular parent or implemented an interface (haven't really gotten that far yet).
What I've noticed though is that I can't setup a default class for my constructor parameter. For example I'd like to do this:
Code: public function DropDownList(containerClass:Class = ContainerSprite, childClass:Class = ChildSprite) However it gives me the following error: 1047: Parameter initializer unknown or is not a compile-time constant.
I created custom component that not derived from UIComponent. And I want to make live preview. It's works fine - I can change properties and live preview shows them immidiatally. But there's some problem - if I override 'width' and 'height' properties and run application - the width and height that I changed on properties panel in IDE are not kept. Properties that changed through component inspector saves. So, how can I save width and height of my component changed through properties panel?
Ach. I have a class that extends MovieClip called AxonClip, and a class that extends AxonClip called Target. I create several new Target objects like so:
Code: Targets[i] = new Target("Targ"+i); Targets[i].attachMovie("TargetArt", "TarGuy"+i, iDepth);
I'm trying to create a series of Loaders in a for loop whose names are created from an Array.If "eval" existed in AS3, the code might look something like this:
var i:int; var tnArray:Array = new Array("tn0","tn1", "tn2"); for (i = 1; i <= 10; i++){
Is my understanding that there are no Abstract classes and you can't override or overload constructors of derived classes correct? Abstract classes aren't important for me but if it's possible I'd like to know how. But is there a way to overload default constructors and I'm just doing something wrong? Can we only override methods or can we overload them also.For a simple game I'm making, I'm not using FlexBuilder and don't want to for this project for specific reasons, so I'm using Flash and instead of using sprites and bitmaps I want to draw shapes in Flash and covert them into MovieClip symbols which I "link" for export as AS to use in my code. I want to make it a little modular so I can just change certain aspects of the code for different approaches.If I create a class Actor which extends MovieClip the default constructor has to be Actor() with no arguments. But I'd like my class to be able to have arguments like initial x and y coordinates. I know you can just create methods to initialize each part but I'd like to try and have a default constructor to do so.
In Flash I notice that if you derive a written class or built in class it requires the standard default constructor, "which I may be wrong about and I hope I am and someone could show me what I'm doing wrong", I found if you derive a class based on a symbol you linked for export as AS I can create a new constructor with whatever argument(s) I want (so this is why I'm making this post,if I can do this couldn't there be a way to override constructors?).
1) So I create a base class called Actor which extends MovieClip save it as Actor.as and default constructor of Actor() add whatever properties I want.
2) Then I create an object in my library, let's call it mcShip, then I link that symbol for export as ActionScript and have it's base class as Actor and name the class ShipMC.
3) I then create a new .as file and call this one ShipActor.as, this class ShipActor extends ShipMC and then I create a default constructor ShipActor(gs:GameScreen, xA:Number, yA:Number) and this works fine (also I create a method in Actor class called ActorSuper and call it from ShipActor with passed in arguments, since I don't know of a way to overload the parent class' constructor)
If I were to just have my mcShip with a base class of flash.display.MovieClip and I try to create ShipActor with the constructor above it says missing default constructor. The above 3 steps is the only way I can get it to work for now. Is there a way to overload the constructor? If not are there any other work arounds?
I am working on Flex project these days and having java background. In my current task, same pop up is opened when two different types of custom events are being fired and I have to hide a button for one event type. So, how i can get event type.
I'm attempting to use the movieClipLoader to load a file onto an instance of a class derived from movieclip. For some reason, this doesn't seem to work, because after it successfully loads, the array that contains these derived class instances suddenly become movie clips and lose all their derived variables (tracing them resutls in 'undefined').So I thought there must be another way. Perhaps there is a way to copy the image data from one movie clip to another, or someone suggested taking a snap shot of the first movie clip and then applying it to the second as a bitmap.
In all the ActionScript examples I come across, people write custom events with the types defined inside the custom event's class definition. But, in my experience, it makes more sense for the object dispatching an event to own its own definition of that event (which, in ActionScript 3, is a String).
[EDIT: After writing this question, I've found there to be cases for both positions -- in some situations, event types should be stored on the event object, and, in others, they should be stored on the object dispatching the event.]
I would like to extends the Event class to add some events I am using in game. But I don't want the new Event Class to have the old public static types. For instance I don't want to have:
NewEventClass.ENTER_FRAME
How do you go about extending the Event class without getting the old types mixed in?
Is there any way to outsmart AS3 to leave out the uneeded types?
Or should I avoid creating a new Event type altogether and just add the new strings?
I'm newish to OOP AS... trying to build a image loader that wipes between loads. having trouble getting my onloadComplete event to call a method in the main body of the class. what am I missing?
Can event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code: pseudo code: class main { main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?
Does addEventListener(ErrorEvent.ERROR, handler) handle all type of error event, for example, IOErrorEvent.IO_ERROR, SecurityErrorEvent.SECURITY_ERROR, and other all error events? I'm looking for addEventListener() version of try catch(e:Error)(e:Error can catch all type of errors).
