ActionScript 3.0 :: Dynamically Add Instance Of A Class?
Jun 9, 2011Im trying to dynamically add instances of a class. I need to do it in a loop. How would I go about doing something of that nature?

View 3 Repliesi have instance of "HelloClass" class on my main movie : _root.mc.HelloClass.variable1.fullurl
so my HelloClass exteds movieclip and has var named Variable1 that also class with var fullurl
i want to access fullurl string value dynamically , somthing like: _root.["mc"].["HelloClass"].["variable1"].["fullurl"]
so i can access every var from external swf
I have recently started out with flash oop concepts and was wondering how to do create an instance of an extended movie class without dragging and dropping the clip from the library ....I have figured out this method..
for(i = 0;i<100;i++)
{var mc:MovieClip = attachMovie("ball","dasd"+i,_root.getNextHighestDe pth());
mc._x = Math.random() * 600;
mc._y = Math.random() * 600;
}
but this way I cant pass arguments to the constructor function of the ball class..
I'm working on a photo-sharing demo using AS2.0, I would like to dynamically load photos (stored as jpgs in the .fla's local directory) into MovieClips, and apply a class instance to them. Currently, for debugging, I've imported jpgs to the Stage, converted them to MovieClips, and then accessed their linkage properties, setting them to the class I need them to implement. But for the final application all of this will have to be done with code.
I know how to dynamically load the jpg into a MovieClip using loadImage(), and I know how to create a MovieClip that is an instance of a class by using attachMovie() with a library symbol and the class name. How do I combine the two? Is there a way to access the linkage properties of a MovieClip dynamically?
i also write this question in as2 forum, but i need it also for as3i have instance of class "HelloClass" on my main movie :_root.mc.HelloClass.variable1.fullurlso my HelloClass exteds movieclip and has var named Variable1 that also class with var fullurli want to access fullurl string value dynamically , somthing like:_root.["mc"].["HelloClass"].["variable1"].["fullurl"]so i can access every var from external swf
View 2 RepliesSay i have a movieclip named a_Mc ( ClassA ) I have a sub-movieclip named b_Mc ( ClassB )
CASE 1: Accessing the sub-movieclip b_Mc which is already present inside the a_Mc movieclip
( Since Flash IDE has "Automatic instance naming" OFF )
ClassA mentions the name of b_Mc as => var b_Mc:MovieClip;
NOTE HERE: That the variable name MUST BE same as the name of the instance on stage.
So i can access it as : trace( a_Mc.b_Mc);

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 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?
I 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.
I'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;

Quick 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?

I have a general / somewhat newbie question. Is it better practice to call a function from another class like so:

Does one way free up more memory or enhance performance?
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();
I'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.
I'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");
Let's say i have a bunch of balls/cells. I'm having trouble figuring out how to make it so that every other ball bounces off of every other ball.
so in short, it's really one instance being able to check all other instances of the same ball class?
When I declare a class variable
private var myVar:MyClass = new MyClass();
It creates a new instance of that class that will trace as [Object MyClass].
However, as soon as I assign it to something
myVar = thisOtherVar;
It will now trace as [Object thisOtherVar].
I need to get it back to where it's just an "empty" blank class instance, if that makes any sense at all.
Given 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...
I have a class called Unit. When I use this class in a .fla file, I create it by saying:
var unit00:Unit = new Unit(...);
So then it creates a gfx representation of the screen for me. I would like to have a method like this:
PHP Code:
[code]....
So how do I get this to work? I know that delete this will not work when defined inside the class. How do I target the .fla's instance name when I don't know what it will be called?
I mean a have a class called Login and when I make an instance of this class
PHP Code: var log:Login = new Login();
doesn't give me the wanted results.
- When it is declared Document class it adds a child on stage
- When the same class is called manually (via the above code) although I get no errors nothing is added on stage.
I'm having a problem where I can't make an instance of a class in one class like I can in other classes all in the same package. When I call the update function from another class it doesn't work. I traced the xPos of the instance of the class I was talking about and I get zero, but that is incorrect so I'm thinking it's the above problem. If anyone knows what the problem is please tell. Here's my code:

I'm creating a Papervision3D scene in a document class. I have added an instance of a PointLight3D object. I'd like to create a class that uses the light instance in the main document class for its material. What would the Actionscript be to do this? I can't refer to the light as super.light because my class is inheriting the Sphere class. parent.light does not work either (even if I wait for the class to be added to the stage).
View 2 RepliesI want to retrieve the var reference of an instance of a class from within the class. For example:
ActionScript Code:

You may ask why, well I want to do some spring cleaning inside this manager class I am making. Of course the above is a simplistic version of what I am trying to do.
how can I self refer to an instance of a class within the class definition file?Here is an example
PHP Code:
public function fireBullet(target:MovieClip) {
Bullet_mc = target.attachMovie("Bullet", "Bullet1", 1);
}
}
Now everytime I want to call the function I have to put this as my target, (fireBullet(this))I cannot just put it in the code as it gives me an error.
This site has a flash slideshow with multiple people in it that scroll left and right. The people are buttons with instance names.
When the user clicks on each person, it triggers some javascript that loads the corresponding swf for each person. Currently it only works for the first guy with a specific name in there.

I have 100 buttons, named k1 till k100.I don't want any code inside the button.I need to make the buttons invisible when pressed.I get a currentframe back from something else (example 22) and at that moment I want k22 to be invisible (k22._visible = 0)
I tried:
aa = k;
bb = 22;
cc = k+22;
cc._visible = 0;
also tried as string "k" "22" but it doesn't work
cc = k22;
cc._visible = 0;
works but I need to make it work from kk+22;
