Know What Class An Instance Is Created From?
Jan 16, 2011In actions script 3.0 I would like to retrieve the class of two instances and then compare them. Is there a way to know what class an instance is made of?

ActionScript 3.0 :: Referencing A Newly Created Class Instance
Jun 16, 2011I am completely new to actionscript although I do come from a OOP background. I have been asked to trial Flash and Actionscript 3 in particular - so I do come with a few preconceptions on how I expect actionscript to behave. I have a problem I donot understand. I have created a new class and to test it I use a simple test harness in the form of a .fla file.
The issue I have is when I create a new instance of the class and assign it to a variable, subsequent background changes to that instance of the class are not 'picked-up' when referenced through the variable. I would expect that given instance of class could be assigned to many different variables and any updates using one variable would accessible using any of the other variables.

Actionscript 3 :: Reference From The DocumentClass A Movieclip Created By An Instance Of Another Class
Aug 21, 2011I have this main (document class) in a Flash project:
package {
import flash.display.MovieClip;
import flash.events.Event;
[Code]....
Now: if I pass a reference (ref) of the main class to Other and I add clippo as you can see in the first case, I can reference the movieclip clippo from the main (getChildAt(0) is "clippo" from the main). But, is there any way to use the second method (no ref) and do the same from the main class? I can see clippo onstage when Other creates it but I can't understand where clippo "lives" into the DisplayList.

Aug 29, 2007I'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.

ActionScript 3.0 :: Keyword "this" - Refer To The Current Instance Variable Being Created When Its The Only One Being Created?
Dec 11, 2009When an instance variable is constructed by a constructor method, why do you need to refer to the current instance variable being created when its the only one being created? I understand assigning an expression to it but why name it "this." when it is the only object that the constructor is building? Does it have some hing to do with being able to naming that object in the Local Variable? In other words am I creating a generic object that will be named in another class?

ActionScript 3.0 :: Access Values Held By A Class Instance From Another Class Instance?
Oct 14, 2009I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
ActionScript 3.0 :: Sending A Class Instance Reference To A Different Class Instance?
Apr 14, 2011I'm creating a little game - The player controls a character that follows the mouse. Pigs run away from the player, and the player has to get them all into a pen. To make the game a little more difficult I'm trying to add an enemy - wolves, that attempt to perform a 'hunt' method every x seconds. This method sends a reference of the wolf instance to Main (my document class) and Main then loops through the pigs on stage to see if there's any nearby. Now as far as I know this works - my problem is I'm unsure how to send the pig instance reference back to the wolf that called the hunt method, so it can then 'target' the pig, and then attempt to pounce on it.
This is my Wolf class:
Code:
package
{
import flash.display.MovieClip;
import flash.events.Event;

Actionscript 3 :: Reference A Class Instance From Another Class Instance?
Dec 10, 2010Quick question. I have been Googling this all morning, but it's either not there, or else written in a way that doesn't register. I am inclined to believe the latter, as this seems like it should be something completely trivial to me. I made a small Flash file using AS 3.0, and this is the first time I've really been able to stick to the OOP way of doing things and not hack together a mix of stuff from the timeline to get around not having everything work in the classes.
So I'd like to keep it that way, but one thing is eluding me: I can't call a method of an instance of another class (than the one I'm calling from) without resorting to "DocumentClass(root).instanceName.method." Intuition tells me there has to be a better way of doing this (like, without having to reference the document class every time I call another class instance's function; and CERTAINLY without having to use the word "root" - that just seems so Flash 5 to me. Does anybody have a better way of doing this that they can share?

Flash :: Get Am Instance Name Of A Dynamically Created MovieClip Or Name?
Dec 4, 2009For AS 3
I have a class which crate a panel with close button. and i create an instance of this class like this
function _smallThumbClick(evt:MouseEvent):void {
var _popup:Popup=new Popup( square.width ,evt.currentTarget.y, evt.currentTarget);
addChild(_popup);
}
and this mouse event from the thumbnail(suppose), so if i click on the thumb it will create popup. so i want to close all other or previously opened pop window.
How do u get the popup class object to close from another class..
or is there any alternate method for detect instance of the movieclip or class..

Actionscript 3.0 :: Assign Instance Names To Xml Created Objects?
May 21, 2009how to control dynamically created clips... What I've got is a series of objects on the stage, that have been created using an external xml file. here's the code for this...
Code: Select allfor each (var MenuItem:XML in myXML..MenuItem) {
code for setting the clips on the stage, positioning them, etc, } But what that doesn't do is give each clip an individual instance name, so I've no way of controlling them on the stage? I presume I need to create a variable and then loop through the MenuItem xml assigning a unique instance as it goes through it?
ActionScript 3.0 :: Creating Instance Names For Dynamically Created Movieclips?
May 28, 2011I am trying to use a for loop, to place 5 instances of the same movieclip on the stage. In the loop I used .name to give each movieclip a unique instance name. But when I try to reference one of those instance names in an event listener I get an error. Here is an example of what I am trying to do:
Quote:
var xPos:int = 120;
var yPos:int = 60;
for (var i:Number = 1; i<=5; i++) {
[Code].....
This code generates an error saying that the cStar2 property is undefined. In the example above, does the for loop create 5 copies of the movieclip starC_moov, and give them unique instance names cStar1, cStar2, cStar3, cStar4 and cStar5?
ActionScript 3.0 :: Accessing A Property Of An Instance Inside A Dynamically Created MC
Sep 17, 2009Im dynamically creating an instance of a movieclip, call it a game piece. This game piece has 4 frames, each with a movieclip called base(although one is red, one blue, one green, one yellow). When the game piece is created I set the frame to indicate player color. Im also changing the alpha of base to 1.0 when its being dragged, 0.5 when its dropped.
Using the following code, everything works fine if the game piece color is set to the base in frame 1 (red). If the game piece is created and the timeline moved to a frame other than 1, I throw an error when trying to access base.alpha (this would be the second, third, and fourth instances of base in the game piece timeline). Heres the strange part, this is only a problem when the game piece is first created and added to the display list. Once created, even after the error has been thrown, I can access the alpha of bases 2, 3, and 4 in the drag start/stop listeners. Heres a link to the work in progress, and the relevant sections of code (shortened for brevity, t1 is the top left piece on the pallet, others just repeat the same code):[URL]

Flex :: TextField Instance Inside A Button Created In A Separate Layer In Flash Is Null
Mar 25, 2010I've created an button object in flash. The button contains 2 layers. One is the background image and on top of it is a textField. The textfield is dynamic. I use the button inside a movieclip and I export it in a SWC. The I'm trying to use it in flex.
I'm trying to do this:
var myComponent:MyComponent = new MyComponent();
myComponent.button01.theTextField.text = "Caption";
I get and instance of the button(myComponent.button01 is not null in Flex debugger), but the instance of the textField(myComponent.button01.theTextField) is null and I'm not able to change the text(but the default text appears onscreen). The code is compiled correctly in flex.
I exported the in swc the button control as well. So the button is not the default SimpleButton from Flash, but an derived class generated by flash(with the same name as the symbol defined in flash). It contains theTextField memeber, which is null.
Here is the button timeline(Layer 2 contains the textfield, and the textfield instance is named theTextField):
Flash :: Creating An Instance Of A Class That Implements An Interface Based On The Class Name?
Feb 17, 2011Is 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 3.0 :: Creating A New Instance Fails When Base Class Is Assigned To An External Class File?
Jul 22, 2009I'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
ActionScript 2.0 :: Eating A Global Listener On The Class And Receive Dispatched Event For Any Instance Of The Class?
May 11, 2006I've done a class to be able to listen to the event for a CLASS not on an instance.
Code:
class net.webbymx.events.XClassEventListener {[code]....
why did I do this.It cames with my rugby game.I have player in two teams. When a player throw the ball I want the other teammate to act like "wait for ball" and the opponent like "seek for ball". Plus I'm lazy (and I don't want to register the listener for each instance of the player I'm creating). So this class is made to be able to handle as many instance of a class I want without adding a listener on each of them. I'm just creating a global listener on the class and then I will be able to receive dispatched event for any instance of this class .so in my team I can do
Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "wait");
and in my opponent team I can do
Code:
XClassListener.initialize(this);
this.addEventListener("throw", "net.webbymx.game.Player", "seek");

Flex :: Difference Between Class Reference And Class Instance?
Jun 28, 2010Given that both of these calls to getQualifiedClassName return the same thing (mx:Label), how would one go about programatically differentiating between an instance of a class and a reference to the class...
var lab1:Label=new Label();
var lab2:Class=Label;
var qcn1:String=getQualifiedClassName(lab1);
var qcn2:String=getQualifiedClassName(lab2);
In other words, how could I know that lab1 is of type Label, while lab2 is type "Class". typeof() simply returns "object" for both... getQualifiedClassName returns "mx.controls::Label" for both...
