ActionScript 3.0 :: Applying A Class To An Instance?
Nov 5, 2009Is there a way in AS3 to apply a class to an instance on the stage? Or is the only way to do it through the linkage menu in the library? The reason I ask is, I have a button class that I'd like to apply to only the button instances on the stage that meet certain criteria

Jul 29, 2010I have created some movieclips and will be using them as buttons. After applying event listeners to them, they do not correlate to their instance names. I have a switch case statement set up to catch when one of the movieclips are clicked on and this is caught, the method is invoked but none of the cases are satisfied as all the buttons have the instance name "instance58" for example....they are all numbered instances.

Flash :: Unable To Convert An Instance Of A Class To An Instance Of The Class's Subclass?
Sep 15, 2011I'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.

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;
[Code].....
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 3.0 :: Applying Two Class Files From A Package
Oct 28, 2008I have a photo gallery, with a thumbnail panel (a photo viewer page) that I made, coding the AS3 from the key frame. It just so happens that I saw some class files online that have some good stuff in the tutorial.I've never really worked with .as files and I am intimidated by them.Would it be easier to modify my photo gallery, with a thumbnail panel, from key frame to .as AS3 code or to go from .as to key frame code? I personally feel more comfortable with key frame AS3, but I am not scared to dabble.How can I practice adding a couple of class files to my key frame AS3 code- I'm using regular variables, but the interesting idea I saw uses private variables and public functions, and it imports some stuff?
View 1 RepliesActionScript 3.0 :: Listener Functions Applying To All MovieClips Using Class
Jan 14, 2009I am currently having a mc in my library use a class. The mc is duplicated and put on the stage. Inside the class the mc gets a rollover state. Problem is that, although the rollover listener and function 'works', any action that is given is applied to all objects linked to that class.
Code:
Select allpublic class cities extends MovieClip {
private var theStage:*;
public function cities(cityid:int, cityname:String, mymc, ref:*) {
theStage=ref;
this.alpha=.85;
this.buttonMode=true;
[Code] .....
So pretty much on rollover on one of the mc's makes them all alpha = 1 and rollout makes them all alpha = .85 instead of the one being rolled over. It does make sense I guess because they are all calling that same function I think. I also tried referring to the specific mc (mymc) instead of the parent and this.

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");

ActionScript 3.0 :: Reassign Class Variable To A Blank Instance Of Its Class?
Aug 31, 2011When 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].

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.
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...
ActionScript 2.0 :: Delete Instance Of Class From Class' Method?
Dec 28, 2005I have a class called Unit. When I use this class in a .fla file, I create it by saying:

ActionScript 3.0 :: Can't Make An Instance Of A Class In One Class?

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?

ActionScript 2.0 :: Self Reference To A Class Instance Within A Class?
Jan 7, 2005how can I self refer to an instance of a class within the class definition file?Here is an example

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.
Actionscript 3 :: Getting The Name Of A Class Through An Instance Of That Class
Jan 9, 2010I have a function that takes as parameters 2 instances of a (custom) class. But they can each be one of several classes, and I need to then call another function based on what type they are. I'd like to do something like this:
function any_any(inst1, inst2) {
this[inst1.classname + "_" + inst2.classname] (inst1, inst2);
}
[Code]....
Should I go and define 'classname' in each of my classes, or is there a better way to get the class name of an instance? I don't know how to get typeof() to return anything other than 'object' for a custom class, maybe it's possible?
EDIT: It would be inconvenient to use the instanceof operator, as each class can be 1 of 6 (currently).
Flash :: "Instance Name At Design Time" Vs "Instance Name Added Dynamically" Vs "Variable Name In Related Class"
Nov 4, 2011Say 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);

ActionScript 2.0 :: Create A Custom Class (Testing) That Would Create A Box When An Instance Of The Class Is Created
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 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?
View 1 RepliesActionScript 3.0 :: Using Class Name As Instance Name
Jun 3, 2010I've got a hell of a lot of MovieClips in a library because they are all different shapes etc, so rather than creating them dynamically I've made them all manually.They all share the same base class in the properties dialog box (apartment.as) but all have an individual class in the dialog box. The apartment.as is as follows:[code]So for example one of the movieclips is called level1_01 and is placed within a movieclip called plan1. Within plan 1 there are a further 20 movieclips all called level1_02, level1_03....etc.When I click any one of the movieclips (that I've positioned on stage) is there anyway use the class name as an instance name? I haven't given each of them an instance name but was wondering whether it's possible to use the class name that I entered into the properties dialog box as it.
