Is it possible to create an instance of a class without triggering the class' constructor?[code]In the case above, say I wanted to play around with a Foo instance, but I really don't want my global.foobarCount going up, nor do i want to pass in any value at all for bar.This could be useful for introspection where you want to learn more about or pass a particular class object but don't want to provide required arguments or trigger anything that the constructor may do.Is this at all possible? (Obviously, new Foo() just doesn't cut it here, since it would throw and arguments error, nor does just using Foo, since that's a reference to the class itself).
I have a document class name elevator and my constructor is also elevator as usualHow to call this constructor function within elevator class? Is is possible or not?
I've got a simple program that consist of a document class and a buttonTemplate constructor class. I need to call a function called updateText that should be in the document class, when someone clicks on a button. So that after each button is clicked, it updates some text in my document class. My event listeners for the buttons are in the buttonTemplate class. My question is, how do you call a function in the document class from a constructor class? Here is my simplified code below
I've read through the Sticky in ActionScript 3.0 forum and looked through other threads in the topic but maybe I'm not using the right search terms. My problem is creating a new object in the constructor method, I've created a package "com.weenz.shutters" and created many class files within that package. The compiler is giving me the following 2 errors for the "Window.as" file[code]...
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying [RPC Fault faultString="Unable to create a new instance of type 'some class'." faultCode="Server.ResourceUnavailable" faultDetail="Types cannot be instantiated without a public, no arguments constructor."] How to import class having overloaded methods using blazeds
what i am trying to do is by pressing zero_btn which is an object in the library to print a number in the dynamic text box ( result_txt ) which is also an existing object in the library and on stage. my knowledge in actionscript is not much and messing with .as files is totally new to me! then thing is that this code when i locate into to .fla file works fine. there is no error with the code i posted, but am sure something is missing ... like calling the constructor of the .as file.In the library the name of it is Zero_btn and the instance name of this object is zero_btn and it is a button.[code]
I am new to AS3 but not to AS2. I have written a simple class and when I import it, I don't see the object that should be created upon calling the constructor. Can you guys tell me where am I going wrong. And I am very puzzled about 'document class'. Yes, I have google numerous threads on "document class" but still very shaky on this matter. Here is my simple class which should place a button object on the stage when I create a new object of this class. Once I have created the BTN class, I have made sure that I have button component in my library, I then instantiate the object by creating a new CS3 file and importing my class: import com.learning.as3.*; var b:BTN = new BTN();
When I test the movie, I get the following errors: 1172: Definition com.learning.as3 could not be found. 1046: Type was not found or was not a compile-time constant: BTN. 1180: Call to a possibly undefined method BTN.
If a constructor takes its parameters as a vararg (...) it seems to be impossible to create a subclass that will just pass on that vararg to the superclass.
There is a related question with fix for this same situation for normal functions: Wrapping a Vararg Method in ActionScipt but I cannot get that to work with a super call.
base class:
public class Bla { public function Bla(...rest) {
[Code]....
Aside from actually moving the handling of the parameters to the subclass or shifting it off to a separate initializer method
is it possible to get the name of a calling function or the constructor from the called function? is it possible to determine the previous function of the thread?
i would like to call some setter functions from my constructor and have my setter functions determine if it was the constructor that called them.
currently, i'm setting a boolean for this functionality, but perhaps there is another way?
public function Constructor(myNumber:Number) { this.myNumber = myNumber; }
How do I call class constructor functions with indefinite number of arguments?
For example:(this piece of code doesnt serve any purpose, just to demonstrate an example)I wish to create a new class Foo with the parameters bar1, bar2, bar3, bar4.
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?
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'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.
I am trying to things efficiently and put as little code as possible on the timeline.
I have a document class loading and working at runtime.
It creates a button that takes me to a different frame on the timeline.
I have a movie clip there. I put a trace in the constructor of the class of that movie clip but it will not show the trace comment in the output window-its not working. There are no errors.
I also tried instantiating the same movie clip from the document class-which worked-but the trace in it's class's constructor still does not output.
I'm making a class called 'player', and really, I don't need a constructor function for it. Do you just outline the function, but don't put anything between the curly braces? Also, I'm a bit new with access levels. If I wanted my functions from my player class to be accessible from the main class, do I make them public?
For Example: package{ public class A { var test:String; public function A() }} class B{ } The code is in the same file, we call B is inner class, then how to call the constructor of class B
I'm doing something - probably very stupid - with an external library swf. That swf so far contains two buttons each with their own classes 'Simple_Button' and 'Simple_Pop_Button'. In the library swf document class I set up an object that lists the available classes:
i have some pretty simple code, i have my document class trying to add a santa class to the stage (simple game ) - but it will not add and i get not errors at all,Santa class:
I have a custom class, MyMC. The only argument the constructor takes is a string, which sets the text of a label inside MyMC.
In the Flash IDE I've placed an instance of MyMC, which is called mcOnStage, on the stage. Through the document's class Main I'd want to perform the constructor function of mcOnStage.
In the AS3 there is a remark, that a Class Constructor is just a method of the class, that is executed when an object of that class is created. So, since the constructor is just a method of a class, how can I call it directly from the other class methods?
I fell on an unexpected comportment with AS3 class definitions this morning. To tell it quickly, I cannot create an instance of a class inside the same class methods.
Here is an exemple :
package { import flash.display.MovieClip; import flash.events.Event; public class Test extends MovieClip {
[code]....
I would like to understand the sub-process that prevents to do that.
constructor function in a Class file. I've built several over my day and never heard a 'proper' answer about them. If your constructor function does nothing, not even set vars or listeners
ActionScript Code: public function MyClass():void{ }
is it proper to keep it in the Class file or is it ok to leave it out completely?Or is this just something of preference? What do you guys think/do?
