I'm wondering what the difference is between creating a new object with a class or function? For example:
Code:
class snake{
this.id = index++;
this._x = 0;
this._y = 0;
}
or
Code:
function snake(){
var snake = new Object();
snake.id = index++;
snake._x = 0;
snake._y = 0;
}
I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.
View 1 Replieswhat is the difference between document class and normal class.
And I have no idea which class should call as document class or call as an object.
Given 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...
just wondering if theres a difference between using

View 4 Repliesi am not very clear what is the difference if you are using this and if you are not.[code]In php you have to use $this to access class properties. But in actionscript you don't.In AS you can trace testVar using this or without it like this:[code]
View 3 RepliesI working on a game project in Flash AS3. I need to pass data from one class (Game) to other class objects (Ships) on EnterFrame and performance is starting to be a issue. I was wondering is there a difference in performance between calling to the Ship a direct function or dispatching an event which the Ship can listen.
another question is where should I put the enterframe function. Is it better to use only one enterframe function and call the methods dispatch events from there, or it will be wiser to put the enterframe in the different objects (Ships)? note: some Ships are inactive most of the time.
What is the difference between the following two function definitions in ActionScript 3?
f = function(arg) {
// body
}
and
function f(arg) {
// body
}
If i keep aside the loose coupling advantage of Events, what is the difference in the way of working of
1) Simple function call
2) Dispatching an event
I don't understand what is structurally different between a Value Object and a Class in ActionScript3. Can any Class be a VO if you decide to call it one?

View 1 Repliesis there a difference between classifying a function 'private' or 'private static' in a singleton? It seems that they both do the same thing. Maybe some difference in performance?

anyway im using flash as3 for about 6 months, and im still kinda confuse in this things like getters and setters, and idk what you call that but here's and example :
private function myBoolean():boolean

idk how to use it, and what it differs from getters and setters,

Code:

And then after instantiate I just calling the method...for testing the "public" and "private" keyword purposing only...
Code:
import TestPrivate;
var obj1 = new TestPrivate();
obj1.getGo();
The result is still can be execute even though I put the private keyword in front of the methods. So what's the private keyword stands for actually...I thought it prevent been get accessed from outside...

Let's say I have a Custom Event Class, and it has several Event types stored in static Constant:
[Code]...
Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?
If I have three classes:
public class Example {
public function Example () {
}[code]............
You can see that the two last classes extend the first one, and both have the 'variable' property. In case that I have an instance of Example and I am sure it is also an ExtendedExample OR AnotherExtendedExample instance, is there some way to access the 'variable' property? Something like
function functionThatReceivesAnExtendedExample (ex:Example):void {
if(some condition that I may need) {
ex.func()
package{
public class Character{
protected var _hp:uint = 50; //Character Health Points
protected var _power:uint = 5; //Damage dealt
[Code].....
I`m instancing a Character and a Player in the Main Timeline, all in frame 1.
When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?
I was wondering why my current code for calling a setInterval on a function doesn't work inside my class.I have this code inside one function, calling a second function.
intID = setInterval(selfReferential, dupe, 30, 0x000000);
The selfReferential keyword refers to the current class,but was defined previously (selfReferential = this; ).I get no errors, but the dupe() function is never called.and I had the selfReferential variable replaced with the this keyword at one point as well.
I'm not sure that I'm on the right track here. I've got what is essentially a 'gateway' movieclip and depending on the CLICK a corresponding movieclip (form) is loaded -- these all being in their own AS file. There are multiple corresponding pages that will all load/close in their own fashion but the 'gateway' will reload in it's own function-- consequently, I have this function on the main_AS. Can I trigger this function from the sub class or do I need to move the 'reload' function to a 'reload' class.
View 2 RepliesI've been searching around trying to work this out for a while now. There's been various ideas popping up, like dispatchEvent etc but nothing that seems to be a clear, simple way of doing this.What I'm trying to do is call a function from a class seperate (but in the same folder as) my document class.Specifically, I want to 'spawn' an object and run a function within that object's class from my Main.as.The snippet I have at the moment is as follows;
In Main.as:
var object:class_Object = new class_Object();
object.spawn();

I keep getting an "undefined property" error when I try to call an external function from within the Doc class. I added the error message to the Doc Class below so you can see where it occurs.
If I take the code from the Tooltip.as below and place it on the FLA's main timeline I can get things working fine, but I would like to move all script to classes. The document class structure looks like this:

Code:

I realize that I could just combine all the code in the Doc class to get it working, but it would be nice to separate out this particular code which has only one use.
