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 :: Creating Different Instance Of Same Class
Dec 29, 2008I am having some problems with creating different instance of the same class in as2..Pretty sure this should work in as3, so I'm not sure exactly.[code] I thought using the new keyword should create a new object independent of other instances..unless constructors are static in as2 and i just didn't know it.
View 1 RepliesAS3 - Error 1010 When Creating Class Instance
Dec 27, 2010When I try to create a new instance of a class that I created from a symbol in the library, I get a 1010 (A term is undefined and has no properties) error. I gave it a class name in it's linkage properties and it extends MovieClip. Is there anything else that I'm supposed to do? Maybe it's a syntax error when I'm creating an new instance of the class. It used just like any other class or datatype, right?

Dec 16, 2009Topic title explains what i want to do. Say I have a variable roomNumber (a string) and in a game where i move about, roomNumber will change (say, room34 to room35). When a new room is visited i want a new instance of my class Room to be created, but with the instancename of what the variable currently is. (point is that i can go back to a previous room, without it being changed because the instance has already been created) so... roomNumber:RoomClass = new RoomClass(); well, it unfortunately works so that the new instance is named roomNumber, and not room34.

Sep 4, 2009I am building a simple tamagotchi - alike application in AS2 and Flash is acting kind of weird on me. Lets say i have a .fla file with all my animations called Kitty.fla, then I have an external .as file called Kitty.as which contains a Kitty class with the itty(attribut i need to give it) function.On the 1st frame on the timeline i have the following:var kitty:Kitty = new Kitty('my attribute');when compiling the movie, flash automatically creates an instance of Kitty but WITHOUT my attribute (its given a default value specified in the code) and then proceeds with the instance according to what i wrote above. So at the end i basically end up with two kitties, one with default attribute and second with the attribute specified by me, while I only need the one with the specified attrribute

Sep 4, 2010I would like to make a new instance of a MovieClip within my library from code written in my keyframe. I relise that you can do this by making a class and using the codeCode:var instancename:movieclipname = new movieclipname(); and with the MovieClips class I would need to extend MovieClip and nothing else. I am unsure if you put in the name of the MovieClip or the name of the MovieClip class in the code above so feel free to correct me.

Nov 7, 2011I have a question regarding AS3 memory management. Supposing I created an instance variable for a Class, in this case or type Sound:

Am I correct in thinking that each time I created a new Sound I would be overwriting the previous allocated memory?
ActionScript 2.0 :: Dynamically Creating Instance Of Extended MovieClip Class?

ActionScript 2.0 :: Objects - XML - Creating A New Instance Of An Object That Uses An Identical Name To An Older Instance Delete The Previous Instance?
Mar 20, 2009Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?

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?

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");

ActionScript 3.0 :: Reassign Class Variable To A Blank Instance Of Its Class?
Aug 31, 2011When I declare a class variable

I need to get it back to where it's just an "empty" blank class instance, if that makes any sense at all.

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...

ActionScript 3.0 :: Creating Dynamic Instance Name?
Jan 13, 2010I have the following code:
var page1:Branch = new Branch();
page1.y = 124;
addChild(page1);
I want to have the value "page1" to be dynamic, along with "Branch". Since there's a number of templates (up to 20), Branch is one of the templates. So it would be nice to use one instance creator. Also, I'm not sure how to get "page1" to be a dynamic value.
The closest to this that I've been able to find is:
star1sp.addChild(this["star"+star1Num]);
except that it doesn't fully address what I want to do. I tried adding in a bunch of "this[load_page]" and "this["page"+curpage]" to my code but had no success. I'm still on the prowl for the answer but wanted to put this out there. It's something I've tried to figure out for some time.
