i'm trying to make a navigation menu and all the sprites in the menu must have the same Behavior. So i make a Base Class for all the Sprites and i add the Events (rollover/rollout) to this class and it works. Now i want to access a method of the sprites Base Class from my DocumentClass, but i don't know how. My Document Class:
[Code]...
get the base class of an object ?
View 4 Repliesdetermine the base class of a Flash library object at runtime, using Actionscript? The toString method gives me the class of the object, but what I'd really like to determine is the superclass of the object. So, if I have an Actionscript class called "Fruit" and I created many different Fruit types in the Flash library ("Cherry", "Apple", etc.), is there a way in code I can determine that an "Apple" is a child of "Fruit"?
View 2 RepliesI have a pointer to a Class object like so:
var temp_class:Class = getDefinitionByName(getQualifiedClassName(some_obj ect)) as Class;
I want to use it to call a static method 'can build' on that class, like so:
function can_build_ot(c:Class, qualifier:Object):Boolean {
if (c.can_build(this, qualifier)) {return true;}
return false;
}
When I do this, Flash CS4 AS3 tells me
1180: Call to a possibly undefined method can_build.
I may be wrong but as far as I can understand it the hitTestObject() method checks to see whether the object is touching a specific instance of another object? Is there a method I can use where I can check to see if it is touching any Object of a specified class?
OR is there a method I can call where I can see if an Object of a specified class exists at a specific X and Y.I am actually working in Flex using an Image component as opposed to using Flash.
I created an array of objects and put an event listener on each of them. My problem is that when the object is clicked, I want to access a method inside the object's class but I do not know how to reference its position in the array. This isn't very clear but hopefully my code will make it clearer.
This line is inside while loops and puts an event listener on every square.
[Code].....
How can I know which square has been clicked?
Note: e.target returns the following error:
ReferenceError: Error #1069: Property placeChar not found on flash.display.Sprite and there is no default value.
class Foo {
public function bar():void { ... }
}[code].....
I have a RemoteObject returning a 'Schedule' class. I've created a client side RemoteClass to map to it. All properties of the class instance are coming in fine. I just not clear on how I go about calling methods on the class. How would I call a setter on startdate?
package classes.remote {
[Bindable]
[RemoteClass(alias="com.site.data.schedule.Schedule")]
public class Schedule {
public var id:int;
public var modifydate:Date;
public var startdate:Date;
public var enddate:Date;
}}
Is there a way to make an static method act over an object of its class that is already on the stage, without using the keyword "this"? I mean, like "generic object of this class: do what I'm telling you to do, wathever your instance name".My goal is to create an method that get called by any object of this class, based on the changing on the value of an external variable, but since I cannot use the "this" keyword to reffer to each instance, I could not figure out a solution.
View 1 RepliesI'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).
Let's say Class A has the flash.events.Event imported. Now let's say Class B extends Class A. Why in the hell do i need to import flash.events.Event in Class B? It makes no sens at all to me.
View 3 RepliesI'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 have this Fla which contains a symbol that is linkaged to a certain class that is in my project. That class inherites a base class named CMovieClip which resides in one of the libraries that is in the class path (and inherites from MovieClip).Of some reason, every change that I do in the base class doesn't seem to influence the resulting linkaged class, much as if this library is cached somewhere that I can't feagure out.I tried to create the same conditions in a separate Fla but it does not repeat the issue.I tried to duplicate the symbol but the issue isn't solved that way.
View 4 RepliesI created a movieclip with a star. Then, I creates a document class and I named it as Main.as.
In that document class I wrote:
package
{
import flash.display.*;
public class Main extends MovieClip
[Code]....
I´m not posting here all the code, but you can easily see that I´m using x_origin and y_origin variables to keep the original position of the movie clip. I will use them to move the star back to the original position.
The problem is that instead of being 20 and 30 respectively, tracing them I see that they are both ZERO. So when I drop the star, instead of going to x=20,y=30 it moves back to x=0 and y=0. I´ve to get the star position relative to stage, but I can´t find anyway!
say that i have a base class called Base, that is Bindable and has a String property like this:
[Bindable]
public class Base
{
public var msg:String;

where msg is some textInput field. I am getting a message from the compiler that....
Data binding will not be able to detect assignments to "msg"
is there a limitation with data binding to a base class?
I am creating a Weapon class for a game and the weapons itself will be the sub classes. The sub classes will hard code some values (such as max ammo and the weapon name).
I trying to access this declared data in the base class constructor, at the moment it's not outputting the values. Is this possible?
I've broken my Weapon class for simplicity:
ActionScript Code:
package
{
import flash.display.MovieClip;
[Code]....
My current workaround is creating a protected method in the base class to trace the information and calling that method in the sub class's constructor, this works fine but this doesn't seem like the most efficient technique?
I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.
Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.
I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.
I have an mc called sunny. In the properties panel I export her for actionscript. I put Sunny in the main class and Drag in the base class. The reason for this is that I want her to be draggable. I can't use Drag in the main class as another object is using that name. The Drag.as has the drag functionality. Why can't I drag her. I already have a solution - I wrote a specific class for her and extended the Drag class. However, if I have 10 mcs I'm not going to write specific classes for all of them. Summing up: Using the base class Drag in properties panel - why isn't she draggable?
View 7 RepliesI have two SWF files which I shall call container and slave. The slave file contains a movieclip that extends from a class I shall call base. base extends MovieClip and is compiled into an SWC. slave includes this SWC as a runtime library, while container includes it as merged (and does reference it so it should be compiled into the container SWF).
The container loads the slave like so:
bgURLRequest = new URLRequest(slaveUrl);
var context:LoaderContext = new LoaderContext(false, new ApplicationDomain( null ), SecurityDomain.currentDomain);
bgLoader.load(bgURLRequest, context);
When this loading happens, I get the error that class base was not found. I suspect this has something to do with the presence of the ApplicationDomain in there. I'm not sure what it does exactly, since I didn't write this loading code myself (but I do know that it's there for a reason so it can't be simply removed).
I have a program where I have multiple classes derived from a base class. I want to take all instances of the different subclasses and put them into an array. Is there a way I can search for anything derived from the base class?For example, right now a get the number of children, then see what they are, so:
for (var i = 0; i < this.getNumChildren(); i++)
{
if (i is "type")

I have written a framework that facilitates RPC calls between AS3 and PHP 5 called FlashMOG. I recently got a forum request that has introduced a pretty bizarre question regarding access control. This will be a lot easier to discuss if you have access to the FlashMOG 0.3.1 client source which is here:
[code]...
The basic idea is that I have a FlashMOGService class which has an RPCSocket member that it may share with other FlashMOGService objects. The idea is that you can create two distinct FlashMOGService objects and have them both connect to the same host/port via socket. I use my special RPCSocket class for two reasons:
1) Let developers use one port but separate functionality into two distinct services...a form of multiplexing i guess
2) RPCSocket adds functionality to the standard Socket class that works to serialize and unserialize data and get it where it needs to go. The essence of the problem here is that created a class with a FlashMOGService object as a member and has tried to assign a private method of his class as an event handler to the FlashMOGService object:
[Code]....
My initial thought is that this should be fine because it's all done within the class. However, when I consider the monkey chain that results in this function being called, it seems almost logical that it wouldn't work. The problem is that the browser freezes when a socket message arrives that tries to call the service's client method, _service.client.firstClientMethod. This client firstClientMethod is attempted when data arrives from the server on the Socket (an RPCSocket, actually). The RPCSocket class deserializes the socket data and extracts an array with a service name, a method name, and an array of arguments. It looks into its own private class variable (an array of services using the RPCSocket) and tries to invoke whatever function was assigned thusly:
[Code]....
I'm guessing there's some kind of infinite loop going on to check access control for the various intertwined classes.
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 creating an application with an animated kid figure. All the kid symbols sit in a kidLibrary.Fla file, Each of these symbols have a class named "Kid" linked to it on its Properties >Base Class. This Kid class is responsible for setting the right color and hair type for each kid symbol instance. Every time i need to include one of these kid symbols i drag it to the current .fla file I'm working on. If I place only one kid symbol in the library of the file I'm working on, everything works fine!
Now here is the problem: When i place more than one kid symbol in the library, and then drag it to the stage, then one of the symbols works fine while the other one doesn't seem to access all the properties of the Kid base-class. The result is that only one symbol act perfect while the other one(s) not.

I'm writing a series of Search windows for an application. I create the FLA files on the stage, each has 3 simple buttons: next_btn, prev_btn, and close_btn. Those all have event listeners which call findNext(), findPrev() and closeWin() respectively. Each search window looks for different things, some with a text box and some with a combo, etc.
So I have a base class com.search that extends Sprite and adds the eventListeners at startup (actually, on addedToStage). Like this:
function isAddedToStage(evt:Event){
next_btn.addEventListener("click",findNext); prev_btn.addEventListener("click",findPrev); close_btn.addEventListener("click",closeWin);}
[Code]....
If I add the event listeners in the derived class rather than the base, it works fine. But that seems to defeat the purpose of inheritance, plus it infers that I won't be able to derive new classes/swfs from those derived classes.
how does one reference objects created on the stage from a base class of that document's class?
I frequently create a lot of Library Symbols, export for Actionscript, letting Flash auto-generate the Class & extending a custom base-class in order to give them all custom functionality w/out having to create a Class for each, and/or without having to create a FactoryClass for instantiating X number of ClassObjects for each Symbol to be added to.It's really fast for prototyping, and with this workflow I've only hit a few obstacles. Those are:
1 - If the Symbol has children you cannot give the children instance-names, else the compiler gives an error related to automatically declaring stage instances. Two workarounds for this are that you can uncheck automatically declare stage instances, and do it manually in your base-class. or you can avoid using instance-names, and use getChildAt().
2 - If the Symbol is a MovieClip, the timeline doesn't inherit the base-classes imports. I don't have a workaround for this.are these limitations that could be addressed by Adobe's Flash team, or are they limitations that are unavoidable without altering the workflow?
That is i have called one AA class in to stage. AA class is extends from BB class. BB class extends from CC class.CC class extends MovieClip.
