View 7 RepliesFlash :: Property With A Public Getter And Protected Setter?
Sep 9, 2011Is it possible to have a property with a public getter and protected setter? I have the following code:
public class Mob extends Sprite {
// snip
private var _health:Number; // tried making this protected, didn't work
public function get health():Number { return _health; }
protected function set health(value:Number):void {
[Code]...
I did have this.health -= dmg; but I split it out to get more details on the compiler errors. I don't understand how the property would be considered read-only within the same class. I also don't understand how it's inaccessible. If I make the backing field, getter, and setter all protected, it compiles but it's not the result I want; I need health to be readable externally.

ActionScript 3.0 :: Classes - Why Static’s (not Available To Any Instances) Properties And / Or Methods Can Have A Public
Feb 17, 2009I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.

Nov 9, 2009I'm having trouble updating a property value of a custom class (SubLoader) using a getter and setter. Inside the if() statement of the main fla you can see my attempt to set the percent value. Running a trace() method before the if() statement always outputs '0' for some reason. Tracing after the if() statment outputs an actual value. I can't figure out why the percent property always traces as '0' before the if statement even though I am updating it with each progress event.

View 2 RepliesActionScript 3.0 :: Pushing Value To Array Via Getter / Setter
Mar 22, 2012I seem to have run into a situation where when I push a value to an array held within a singleton via a getter/setter , Flash seem so access the getter over the setter method. Within my command/controller (I am using RobotLegs)
override public function execute():void {
// various line of code here
//Place screenshot image into an array from model for later reference.
model.unitScreenshots.push(screenShot); // screenshot is just a Bitmap object
}
The getter and setter within my model e.g. robot legs singleton
public function get unitScreenshots():Array {
return _unitScreenshots;
} public function set unitScreenshots(value:Array):void {
_unitScreenshots = value;
}
When I set a break point on both the getter and setter, only the getter method is being called, why? I would think that a push value on the array would trigger the setter, not the getter.
Actionscript 3 :: Getter And Companion Setter In Different Namespaces?
Oct 11, 2011I'm trying to create a property that can be set by extending classed and read publicly.I couldn't think of a good naming convention for a protected property with a public getter, so I tried to do this:
public function get name():String{ return _name; }
protected function set name(string:String):void
{[code]......
However I get the error (when trying to set name in an extending class): 1178: Attempted access of inaccessible property name through a
reference with static type testing:TestComponent.1059: Property is read-only.
If I change the setter to public, it works fine.
Actionscript 3 :: Getter / Setter Class & Scope In OOP
Feb 19, 2012I recently completed a tic-tac-toe game in AS3, using some simple function-based code I had written in C many years ago.Now I'm on a quest to do it the "right way" using OOP techniques and best practices.Everything is now divided into neat little packages, it looks pretty, and the last part of my journey is to get all the little buggers to communicate with each other.I want to move the code which holds the game state from my main to it's own class in com.okaygraphics.model.GameState.The problem is nearly every other package gets and sets these game state properties.I'm trying to figure out the simplest way to encapsulate this stuff, while still allowing my other classes to access it.
1) Do I need a constructor? I mean, my program will never have more than one GameState. If I should call my getters/setters as instance methods, how do I get each other class to reference the SAME instance from their respective packages?
2) Do I even need getters and setters? Perhaps the class could just have 3 public properties? If so, how would I acheive the proper scope with regard to my other classes?
3) Should I assign everything to the class itself using the static keyword? If so, how would I implement and use those static methods?
4) Is this a mistake? Did I totally just program myself into a corner?
ActionScript 3.0 :: Writing Getter And Setter Functions?
May 26, 2010I have two functions one that sets and one that gets a number. The set one works, but the get one doesn't. I have it trace the set it returns the correct number, but when I set the getY function, it doesn't give me anything at all. When i took the number out of the trace it just gave me back only text. What am I doing wrong here?

ActionScript 3.0 :: Custom Class Setter / Getter Are Blank
Oct 23, 2009I have written a class, which is basically a textfield for forms. It will eventually have several validation modes built into it too, which will be set by setting a property of the object.anyway, my problem. Basically my setters are empty if the movie is used as a loaded swf within another movie.I have an Event listener within the class listening for the Event.ACTIVATE event (still not sure exactly what this does...) though i do know that i need this in place for the setters/getters to work.If i create objects from my class, set some properties everything is spot on, though the moment i load this working movie into another movie the Event.ACTIVATE does not fire.[code]Now, if i run this movie its perfect - everything works as it should, right down to the validation.however, this movie is to be used within another movie. When i load this movie into a parent movie my fields aren't added to the movie.
View 5 RepliesActionScript 3.0 :: Getter Methods Good Practices?
Mar 11, 2010If I've got a getter method, say a(), that returns the private variable _a. Obviously from outside the class I call instanceOfClass.a. But from inside the class, should I use the getter or directly _a? Suppose I'm writing a method that uses _a: should I use _a or a? var b = a; or var b = _a? Maybe for performance reasons it's better to directly access _a? Or since there's a getter a(), it's a good practice using always and only the getter?

Nov 28, 2009The generally used workaround for this, is to use a regular function instead of a getter/setter. This results in having to have ( ) after the function variable obviously. The question is, can a Function variable be assigned to a getter/setter function and retain its attribute of not needing brackets.

Actionscript :: Static Versus Instance Methods
Dec 23, 2009I'm working on a video player and I initially developed the player with everything in the .FLA file with no classes. Then I started modularizing my player into classes and realised that my classes are static methods rather than instance methods which doesn't seem to be needed in my player. My question is - is this a bad design to have all of your classes methods to be static rather than instance methods ? As I dont see the need (yet) so that's why i geared more towards static methods, is this a bad design?

View 5 RepliesActionScript 3.0 :: Is It Really THAT Bad To Use Public Properties
Jul 26, 2011So the reason I'm asking is..I have like 2000+ lines of code in 5 different separate classes. And they ALL have public properties and methods (as in, ALL the properties and methods are public). This is a fairly complex tile game 2d platformer. And yet everything is working fine. From what I've read, it seems that it 'MAY' cause problems later, where you might make a mistake and call a property twice, or call it 'wrongly', which then 'MAY' cause a bug that would be hard to backtrack.
There are surely many other reasons why not to do this..but if everything is working smoothly so far, should I really go back and try to make every variable private and recode this engine before I get to far?
Actionscript 3 :: Is There Any Advantage To Using Properties Over Public Variables
Jun 14, 2011This might be a very stupid question, but I have to ask it anyway. I am graduating in about a month and while studying, I have always been taught to use properties instead of public variables. So I started wondering what the advantage was and I must say that in some cases, I have no clue at all. Of course it is handy when some other logic needs to be executed when setting properties or getting properties, but is there any advantage to using properties when you are only getting/setting a variable? An example of what I mean is shown below (As3).

OK. I then need to run through each of them and check for a collision with an object from the main stage (called redDot), which I pass to a method (called doDamage) within the class. I'm using the following code:
for (i=1;i<=maxpersons;i++)
{
if (game.getChildByName("person"+i).hitTestObject(red Dot))
{
game.getChildByName("person"+i).doDamage(redDot);
}
}
I keep getting an error saying "1061: Call to a possibly undefined method doDamage through a reference with static type flash.displayisplayObject."!
It just won't work. I've tried altering the code to:
game["person"+i].doDamage(redDot);
but I get an unexpected trace output saying "TypeError: Error #1010: A term is undefined and has no properties."
