ActionScript 3.0 :: Displaying A Symbol Through Class Constructor?
Apr 10, 2009
i have been working on this project. I made a class with a empty blank symbol.
package {
public class imgHold extends MovieClip {
public function imgHold (imgSrc:String)[code]....
I want to be able to add this class on my stage and put in a string in the contructor parameter and the class will display w/e symbol accordingly. How would i make this class link to different symbols depending on the parameter in the contructor?

(Spoiler alert: It's not an issue of my package statement not reflecting the location of my class file.) When I have a class linked to a MovieClip in my library and that class takes an argument in its constructor method. That class will compile properly ONLY when it's located in my top-level directory (same dir as the .fla and Document.as files). If I move that class to a deeper directory, say com.place, the compiler will generate error "1136: Incorrect number of arguments. Expected 0.

I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?

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 want to clone a class object. I tried following from here:
package
{
import flash.net.registerClassAlias;
import flash.utils.ByteArray;
[Code]...
BUT this only works when the class has a default constructor and not when it has parameterized constructor:
how to clone a class object when the class has a parameterized constructor?

I'm on a mac using CS5/AS3 and I'm having trouble getting the ® symbol to display in a dynamic textfield embedded with a Chinese font (Hei - but others fail as well). I can type the ® symbol into the textfield in the authoring tool, the problem occurs when dynamically populating the textfield via XML at runtime. I have tried multiple Chinese fonts, multiple encoding types in the XML (unicode, html, etc) and all characters are embedded properly as far as I can tell. I'm not having font trouble in general, all other characters and symbols I have tried work fine except for the registered trademark,

Library symbol "Card" is linked to class "Card" which extends "MovieClip". Library symbol "Card" contains a card background image.Library symbol "Ace" is linked to class "Ace", which extends class "Card". Library symbol "Ace" contains a TextField with a big letter "A".So we have Ace extends Card which extends MovieClip. Ace therefore extends MovieClip, but does not DIRECTLY extend MovieClip.When I drop an instance of Ace on the stage and compile the clip, all that shows up is the big letter A. However, I expected the background image from Card to be included, since Ace extends Card, and the Card symbol contains the background.It seems like Flash ignores symbol content unless it belongs to the top-level class being instantiated.I think it's LAME that one symbol can't extend another. The IDE could easily draw Card as a non-editable background while I'm editing Ace which extends it, and it should instantiate Card's content and then Ace's content when an Ace is instantiated.

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?

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:
Code:
oClasses = {"Simple_Button":"com.Home.Button.Simple_Button",
"Simple_Pop_Button":"com.Home.Button.Simple_Pop_Button"};
In the swf that loads the library swf I process that object and create another object with proper class references based on it:
Code:
function initHandler(event:Event):void {
defineLibraryClasses(event.target.content.getClasses(), event.target.loader);
addBtns();
}

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.

Now, when I try to create my Example:

var example:Example = new Example(myObjClass);
I get message, that I'm not passing any variable (Error #1063). Why is that? What is wrong with it?

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?

How to create new class instance without calling constructor function, meanwhile constructor function must exist and is requiring 1 parameter.
var newclass:myclass = new myclass; <- still calls function myclass in myclass class
I would like to call constructor function later:

This is my first post. I'm new to actionscript, but not to programming. I hope to learn a lot from these forums. To the point: I decided a few days ago that I wanted to create a flash game. I'm taking an object-oriented approach to the game design since that is what I know. The issue I am having is that I have a class called Hero that inherits from a class called Entity. Now my issue is that I don't want Hero to call the Entities class constructor when I initialize a new Entity.

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.

Some of the top level classes can be instantiated as well as called as a function (e.x. new Number() and Number(), new Boolean() and Boolean(), new Array() and Array()).
Usually this is used for type conversion or as a shortcut for instantiation. I would like to be able to do the same thing:

What I wanted to do originally was to create a logging class to interact with Flash/JavaScript, and be cross-browser compatible. I wanted to be able to use the log function as an alias of a method in the log class. This got me to wondering whether I could implement a custom casting function just because. I've now realized it's not possible, but was fun to play with anyway.
