Flash :: Unable To Convert An Instance Of A Class To An Instance Of The Class's Subclass?

Sep 15, 2011

I'm using a library that has a function that returns an instance of some class Engine.

I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:

var engine:Engine = generateEngine();

to this: var interfacedEngine:InterfacedEngine = generateEngine();

It gives me a runtime error (elision mine):

TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.

What about AS3 classes am I misunderstanding?

ActionScript 3.0 :: How To Convert Script To A Class

Jul 6, 2009

i have a peace of code, that applies only on 1 movie clip called "thumb" on the stage, what i would like to do is to convert this script to a class, and then make whatever i have on stage follow the instructions of the class note that some variables take information from the "thumb" like: var currentX:Number=thumb.x;
var lastX:Number=thumb.x;

so how are these variables going to get data from several movieclips later?

ActionScript 3.0 :: Possible To Convert A MovieClip To A Class At Runtime?

Mar 8, 2012

I have a class which takes in another class as one of its parameters, and creates instances of it according to certain rules.In the past, I've had no problem with passing classes from the library to that class, which obligingly does its magic.In this case, however, I'm dynamically loading an image at runtime. I'm trying to wrap that image in a MovieClip, and somehow pass that clip *as a class*, to the one that creates multiple instances.Is this possible? I thought I'd cracked it with something like:

var apples:Class = Class(getDefinitionByName(getQualifiedClassName(theMovieClip)))

Flex :: Load Several External Images; Getting Cannot Convert To Class?

Jul 16, 2009

I'm trying to load a bunch (about 100) of images into memory, so I can display them at various times. Originally I had simply embedded them, but that of course resulted in the swf file being larger than I wanted. So now I'm trying to change it to load them in the background because they aren't needed immediately.There are probably plenty of problems with this. The current on is that I'm getting an error that says 'TypeError: Error #1034: Type Coercion failed: cannot convert "foo.jpg" to Class.'

I've been googling this awhile, assuming loading an external image is a common thing. That's where I got the Loader and URLRequest code, but I'm clearly missing something. Maybe it's due to my goofy looping logic.Here's the class so far

public class CardImages2
public static var fooImage1:Class;[code]....

ActionScript 3.0 :: Calling A Function From An Extended Class Inside A Top Level Class

Sep 23, 2009

public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt


I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.

So I added the if (defender._hp <= 0) which gives me the following error:

1061: Call to a possibly undefined method win through a reference with static type Character.

"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name

Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?

Actionscript 3 :: Recasting Member Of A Library Class To New Type In Extended Class?

Oct 14, 2010

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.

Flash :: Creating An Instance Of A Class That Implements An Interface Based On The Class Name?

Feb 17, 2011

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();

Actionscript 3 :: Flash CS5 Reference A Display Object From A Class Other Than The Document Class

Jul 28, 2011

Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:

stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for (am I supposed to pass something to this class from the document class?)

Actionscript 3 :: Can A Document Class Extend Another Custom Class That Extends MovieClip?

If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?

For example,

fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass

I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
