Javascript :: Instantiate Within Abstract Class?
Feb 11, 2011I have an abstract class which gives specific 'base' behavior to multiple sub classes. I want to instantiate a Singleton inside this abstract class. Is it good practice to:a) instantiate a class within an abstract classb) do this with a Singleton (I know these may be frowned upon)For clarity I will give an example, the method instantiating the Singleton is:
public function createErrorRepository(repositoryType:String):void {
this._errorFactory = ErrorFactory.getInstance();
this._errorRep = this._errorFactory.createErrorRepository(repositoryType);

ActionScript 3.0 :: Purpose Of Having Abstract / Interface Class?
Feb 2, 2009whats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?

Flex :: Spark - Adding Custom Class To Implement Simple Grid?
Apr 13, 2011To start - its best to say im new to Flex / OOP in general. I have been trying to add a custom class based on StrokedElement in order to implement a simple grid (not like the existing Flex Grids - this would just be for display - not holding elements etc...)

Java :: Flex - BlazeDS And Class In WAR File - Implement Server Side Process?
Oct 26, 2009I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).
ActionScript 3.0 :: Method In A Class File That Refers To Itself - The This Keyword Is Not Working?
Sep 27, 2011Code:
package

import flash.display.MovieClip;
import flash.display.Graphics;
public class Rail extends MovieClip
[code]...
this is a simple Rail class, what I am trying to do is take the for loop out of the timeline and build into the Rail class itself. How do I refer to the Rail class itself within the method? If I am doing this the wrong way please let me know! Would it be better if I created another class, say a "RailSpacing" class and build the for loop into the contructor into that?
Also, if I wanted to add depth to the rail(textures or something else to make it look real) and still be able to change the color without transforming the entire rail instance, what could I do ActionScript wise. I have come to the conclusion the only way to do this is creating a multilayered movieclip and target the base object and not the highlight/ shading layer.
Also, if I created a nice graphic/movieclip and exported it for ActioSncript, how can I find the class file and add too it? Is this even possible? Is it possible to draw something that is detailed and export it and then add some methods?

But where do I put the code which extends the MovieClip?

ActionScript 3.0 :: Error #2071: The Stage Class Does Not Implement This Property Or Method?
Oct 8, 2009I'm having some trouble implementing a "virtual" camera for use in game development with Flash CS4 ActionScript 3.0.Basically, what I'm trying to accomplish is to have a camera that moves about the main stage so that my character can traverse the level which is much larger in size than the stage itself.I've been using Sham Bhangal's virtual camera script, and when I implemented it by sticking the code into the first frame of a movie clip, it worked great!
From there, I moved the code into a document class that i could instantiate and then drop onto the stage as a child.Finally, I wanted to have a main "builder" document class that would be added to the main stage as a child, and within THIS class I wanted an instance of the virtual camera. This is where I hit some obstacles.how to properly instantiate the virtual camera within the builder class which is then added to the main stage. I have a Stage reference that is being passed to the main builder, but I don't know where to go from here. To what do I add the virtual camera to as a child? To the Stage reference in the main builder class? To the main builder class itself?The main issue is that when I export my movie with the virtual camera added as a child to the Stage reference within the main builder class, it complains that I'm not allowed to access certain values.
Code: Error: Error #2071: The Stage class does not implement this property or method.
at Error$/throwError()
at flash.display::Stage/set x()
This happens when I try to access parent.x from within the virtual camera class. I assume this fails because "parent" from this perspective is the main builder class, but using the Stage reference produces this same error.I am, of course, willing to provide more detail if something I've written is confusing, and I will gladly provide a detailed fix for those seeking to use a similar solution in the future.
ActionScript 3.0 :: Error #2071: The Stage Class Does Not Implement This Property Or Method

I am using a document class, here it is:

As for why I'm trying to move the stage, I have a movieclip which moves according to keyboard input and i want the stage/Background to always center on him.

ActionScript 3.0 :: Abstract Multiple Buttons To Use The Same Function?
Jul 16, 2009 I'm building a demo that has a keyboard in it. Obviously, people will type stuff with it and it will go into a dynamic text field. So I have a full keyboard (a movie clip named "keyboardStandard") made up of button symbols. That is placed in the same frame as the text field. Then I wrote this code, using the Q key ("keyQ"):
Code:
keyboardStandard.keyQ.addEventListener(MouseEvent.CLICK, addQ);
function addQ(ev):void {
enterPlayerID_txt.appendText("Q");
}
This works just fine, the Q goes into the text field. However, I sure as heck don't want to write 26 event listeners, then 26 more functions, even if it is copy paste. That's just gnarly. Plus, there are actually 3 keyboards - a numeric and special char one as well I need to handle.I seems passing a parameter from the event listener is not doable?

I can export them as flv also.How they are created? Is it in flash itself or from some other programs like after effects or something?I would like to create such effects for myself. If it is not in flash, then there is no point in wasting time figuring out the methods by myself.
