IDE :: Function In Class Subclassing Sprite?
Apr 15, 2010
I have a class which subclasses Sprite (Class1). In this class I draw something on the stage. I have another class (Class2) that creates several instances of the first class (Class1) and places them on the stage. As I am creating the instances of Class1, I am adding an event listener for the CLICK event for each instance.When I click on any of the Class1 instances, I would like to execute a public function in Class1. However e.target is Sprite and I cannot conver it to type Class1.

Basic OOP question... I want to add a couple functions to the Array class so that my program will be amazing and make me rich and famous overnight. So I create a new subclass NewArray which extends Array. Do I need to write a constructor method for NewArray? If I leave it blank will it just use the parent's (Array's) constructor method?

I would like to take advantage of all the goodness of the newer Vector class for FP10, but it seems it is marked as final. I am doing some intensive mathematical processing in Actionscript, and repeatedly process arrays of Numbers. I have previously been using my own subclass of Array(I call it NumericArray), with added functions such as sum(), mean(), add(), multiply(), etc. This works very well and allows for some clean OO code. However, I am finding through profiling that about 95% of my processing time occurs in the functions of these objects. I need more performance out of these arrays.
I want to use a Vector, as it provides some performance enhancements. I want to specifically use a Vector.<Number>. Unfortunately, I cannot subclass Vector as it is marked final. What is the best and cleanest way to imitate what I was previously doing with a subclass of Array, to a Vector.<Number>?
I have thought about passing around Vector.<Number> variables instead of my custom class and just using utility functions to manipulate, but this is not good OO design and will be a pain to use, not to mention ugly.

There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.

I created a class, extended the sprite class, and now in the constructor I am trying to set the Sprite's width and height properties which are inherited from the DisplayObject. However, after I set this.width and this.height, and print the values, I get 0 for both.
What the heck is going on? When I view the livedocs I see that DisplayObject has width and height listed as public properties. I have been able to instantiate a Sprite directly, and set the width and height after it's been instantiated, so I don't get it.
package {
import flash.display.*;

i have a BasicMap.as that takes an Array and populates itself with the MC objects passed to it by a String reference.it inherits from Sprite, and so it just places the objects on its self.then i have a class that inherits from that class, and gives a little more functionality to it, but in order for it to do that, it needs to place the objects not on itself, but instead inside a holder Sprite, so here is my problem:
code:
package Mushroom{
import flash.display.Sprite;

I'd like to get more of the actionscript into class files and off the various time lines. The problem is I can't make it work. I have a class file called dezynworks.aegis.TextPanel Container.I have a MovieClip in my library called TextScrollWinow. Linkage for TextScroll Window: Identifier, TextScrollWindow; class: dezynworks.aegis.TextPanelContainer. Now I read on a web site that dragging the clip to the stage would retain the class association. That is news to me. I thought you had to use attach. Regardless, neither way seems to work.[code]The attach works. The clips appear on the stage, but the class is gone. dummy.init() (a method of the TextPanelContainer class) is never called and the instanceof statement returns false. There are no compiler errors. There are no runtime errors. I've set up test cases in a new Flash file and it all works like I expect.I've tried deliberately gumming up the class name and introducing syntax errors into the class file. It seems Flash is finding the file okay. Something must be failing silently, but I have no clue what and I'm out of ideas.

the difference between Extending and Subclassing with regards to AS3 classes? I've been under the impression that the two terms meant the same thing, but it seems I'm wrong.

I've recently inherited an AIR project, which is basically a widget that displays product images and static content (contact details etc) on the desktop.The original project was developed in CS4/AS3, and has been published and works fine. Since then, the original developer has gone overseas and I've been hired to make new versions of this widget, UI reskins, different products, etc. I work in CS3, so I've had the original Flash authoring file saved down, gotten Flash CS3 to be able to publish for the AIR runtime, and found the relevant AIR classes that I need. This has all gone smoothly.
The problem I'm having, is that there seems to be some strange way that the original developer has linked the library items to their relevant classes, and I'm trying to unravel this.I'm going to use the clip called windowApplication as my example.In the library, there is a movie clip symbol called 'windowApplication'. In its linkage settings, its class is set to 'windowApplication', and its base class 'com.aca.windows.Application'.The Application class extends the MovieClip class.However, when I test the app, I get compiler errors
'5000: The class 'com.aca.windows.Application' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.'
'1151: A conflict exists with definition SectionBackground in namespace internal.'
(SectionBackground is the first variable declaration in the Application class. Commenting it out makes this error change to the second variable declaration).
I can remove this error by changing the class of the 'windowApplication' symbol to 'Application' and setting the base class to 'flash.display.MovieClip', however that doesn't seem to instantiate the class properly. The symbol appears onscreen, but none of its instantiating functions are called.
The windowApplication object is instantiated using a getDefinitionByName call. I've had a google and looked around various forums, and I've seen suggestions that classes used in getDefinitionByName need to also have a fake instantiation so that they're compiled in Flash. I've tried this but it makes no difference.It seems to me that the getDefinitionByName call is working properly, as it does bring up the correct symbol - but only when the base class is flash.display.MovieClip.
I had another movie clip, called sectionMain, that also had this problem. Its original class was 'sectionMain' and its base class is 'com.aca.sections.Main'. It, too, threw a compiler error 5000. I changed the symbol's class to 'Main' and the base class to 'flash.display.MovieClip', when testing the app, this brought up the symbol. When I changed it back to the original settings, it worked fine, the object was called properly and I could interact with it. However, when the errors with the Application class are thrown, I also get the 5000 error for the Main class - without having changed anything.When I change the class of the windowApplication symbol to 'Application' instead of 'windowApplication', I get a warning that Flash can't find the class and will create one at runtime.

I need to trigger a function or reset a variable from within a sprite when it gets to a certain frame. I keep getting the error "Call to a possibly undefined method" when I call a function and I get "Access of undefined property" when I try to reset the variable directly. Both the function and variable are set globally in the first frame of my animation.

I'm creating a jeopardy like game and have run into a problem. when you click on the dollar amount a create a sprite on the fly and inside the sprite is a shape and some textfields. One of the fields is an input box. once you enter in an answer and press enter I create another sprite with a textfield inside it to let you know if the answer is right or wrong. Herein lies the problem. once your told if your right or wrong, I want the sprites to stay on the screen for 3 seconds then disappear.
I can get them to stay on the screen, but I can't get then to disappear because I can't pass the sprite to the function that I created to remove them. So everything works except the remove function. This is the error I get when the remove function runs: "TypeError: Error #1009: Cannot access a property or method of a null object reference."
I'd post some code but its broken What I'm looking for is just information on how to assign a sprite to a variable so I can use it in a function. if thats not possible then is there a better way to do what I need done?

I'm tryin to set the global focus to a specific class that already exists on the stage after I remove a popup dialog from the screen. I pass the name of the class that was on the stage before the popup dialog is shown by string to the popup class.So public function PopupMenu(pClass:String)after I remove the popup dialog, I want to restore focus back to the previous class so it can accept key events again.How would I set focus to an instance of an object on stage. Currently I have something like this:
Main.mainStage.focus = (InteractiveObject)(getDefinitionByName(prevClass));
but it returns this error: TypeError: Error #1034: Type Coercion failed: cannot convert com.cox::IdleScreen$ to flash.display.InteractiveObject.

I'm wondering (based on scoping rules) how I might do the following: I want to draw to a sprite that exists on the main stage in which I have a class instantiated.
So something like
public function MyClass(reference:String){
this.reference = reference;
}
[Code]...
Would I use super() in this case, or what's the usual methodology?

I am trying to build a flip clock that utilizes filmstrip pngs. I have the main class instantiaing instances of the flipper class to hold the different number postions of the clock and then I want to tell the flipper instances to animate when the timer reaches a certain point in the main class. The problem is when I tell the flipper class to start animating I get a null value error from the flipper class.[code]Ok I guess writing it our helps figured out that the flipper wasn't through loading when I tried to call its properties, duh. Now can someone refresh my memory on how to broadcast an event to the Main class when the flipper class is done animating? I know I have to set bubbling to something but can't remeber exactly what it is. Also its not letting me create a singleton instance of the Main class in the Flipper class, I've done this before in other projects can someone tell me what I am missing on this one?

So I've got this function to make a sprite walk:

But what do I have to do to get the function to adress various versions, such as
chibi.bluejeans1.rtleg._y = 4 + walk; chibi.bluejeans1.ltleg._y = 5 - walk;
so that I can address each type for walking accordingly, through something like
wlk(tunicpants1);
wlk(bluejeans1);

So I have a class that extends sprite. When I call an instance of my thumbnail object, I apparently can't use typical transforms on it by accessing .x and .y properties. These are not inherited from the superclass? Do I need to tell it to inherit these traits?

i'd like to add all or most of my mouse events to stage, but in order to do that i need to be able to tell what is the type of the sprite being clicked.i've added two sprites to the display list, one of which is from a class called Square, the other from a class called Circle.
var mySquare:Sprite = new Square();
var myCircle:Sprite = new Circle();
addChild(mySquare);[code]...........
so far i know how to do is determine if it IS a sprite display object, but since i'll only be working with sprites i need something more specific.rather than checking "is Sprite", is there a way i can check "is Square" or "is Circle"?
if (myArray[myArray.length - 1] is Square)

Is there a way to add text programmatically in as3 to a Sprite or a MovieClip without using the class TextField
TextField inherits from InteractiveObject which is kind of heavy for what I want to do: just display text (i.e. I don't want to interact with the text).
Note: I'm aware that there is a property selectable to make the textfield not selectable. This is not the point.
