Actionscript 3 :: Passing Parameters To The Constructor To An Object?
Sep 30, 2011
I am working on a side-scrolling platformer game. Because of this, I have a class that acts as a floor. I also have a class representing enemies. I am having problems with passing a parameter to a custom class' constructor. The class (SkullDemon.as) extends MovieClip. I am trying to pass an instance (called "floorL1") of a customer class called "FloorLevel1." "FloorLevel1" also extends MovieClip (I do not have a written .as file for "FloorLevel1"; I just exported the floor MovieClip to that class).
I am trying to pass an instance of "FloorLevel1" so that the "SkullDemon" object can land on the floor just like in a platformer. My main class is called "TME2_Main." This is the class from which I try to pass the "floorL1" instance to the "SkullDemon" class. This is how I try to create a Skull Demon instance and pass "floorL1" to its constructor:
[Code]...
What am I doing wrong here? I have spent a while looking for solutions (including moving code outside of TME2_Main's constructor),

is it possible to obtain the instance name of a class from the class without having to manually pass the instance name as a string parameter to the class constructor?
//Create New SizeClass
var big:SizeClass = new SizeClass();

I have the Class and the parameters of its contructor as an object. What I need to do is a function that returns an instance of this class, passing this parameters to the constructor.
This is the code:
Some random and unmodifiable class:
public Foo {
public function Foo(a:int, b:String) {
// constructor
}
}
And some function (in some another class):
function bar(params:Object):* {
var baz:Foo = new Foo(params.a, params.b);
return baz;
}
What I need to do is make this function generic, without pass params as parameter to Foo constructor because I can't modify it. Something like:
function bar2(clazz:Class, params:Object):* {
var baz:* = new clazz(/*some magic way to transform params in comma separated parameters*/);
return baz;
}

I want to serialize ThugtrisShapes' children (heritage/polymorphism) but his children like Right_LShape take constructor parameters,i have to assign it a default value (in my case null because they receive an Array type), but i get this error even when implementing IExternalizable.
Take Note: IForm extends IExternalizable.
here is a link i found about it but it still does not work...[URL]
Code:
public class ThugtrisShapes extends Sprite implements IForm
{
var squares_:Array;
var numsquares_:int=MAX_SQUARES;

I know that not all class' can be cloned , but cloning is an important aspect of OO programming.... There should be a solution for my problem,besides taking the parameter out of the constructor and add a setter.

When using ObjectUtil.copy() on my object, I get the following error
Argument count mismatch on foo.bar::MyObject(). Expected 1, got 0.
MyObject's constructor takes in one parameter. Is there a way for me to clone, or copy it?

I'm trying to set 2 object each with different data, and pass it into another function as parameters, but when I trace for the data in the object, I can only get the 2nd object data. Seems like the 1st object was replaced by the 2nd object.

I know this should be very simple, but in following the examples I can find on passing parameters from HTML to my Flash App I have not been successful. I would like to find a relatively current example using AS3, Flash CS4. I need to pass the url of an XML file off to the flash app so that it can go pick up instructions on what it is supposed to be playing. We want to do it this way because we don't control the web site so we can't just leave the XML file on the server and maintain it as needed.

I'm working on a very simple dependency injector, reflecting on a types constructor parameters.But when ever I use the describeType on my custom classes, all I get in the constructor packet of the returned XML is something like this:
<constructor>
<parameter index="1" type="*" optional="true"/>
</constructor>

Let us assume I have classes "Main", "Sub1" and "Sub2". I also have interface "Inter".[code] Basically, I want the constructor function of any class implementing "Inter" to take the same parameters, and thus avoid initialization errors. (So as that the code above gives a compiler error) With any other function,[code]But As the constructor name differs from function to function, I cannot do this.

So I usually use an object in the constructor to receive the parameters like new Class({param1:00,param2:0099,etc).To be able to access those parameters from other functions inside the class I create an object, and copy it:
Code:
public class MyClass {
var params = {};
public function MyClass(p){

I know I can create instances from a string like this:
var classFromClassPath:Class = getDefinitionByName(classPath) as Class;
var instance:Object = new classFromClassPath()
I know I can call some function with a parameter array like this
var x:Function = someFunction;
x.apply(null,args);
But does anyone know if I can pass parameters like that when I construct a class?

Is it possible to define 'public properties' of an object in the constructor method when you create the object ? similar to..
var leftmain_scrollertext = new TextField({length:10});
I have a TextField and I want to set its maxChars, x, y, width etc.
when I specify one or more of these I get... 1137: Incorrect number of arguments. Expected no more than 0.
am I forced to specify each property I want individually after I have constructed it ?

There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.

I am going through the book gameprogramming university and checked to make sure my code matched.
I am using 2 classes the main class attached to the timeline, and an airplane class that contains a symbol in the library with different frames.
the main class is
Code:
package {
import flash.display.*;
public class airraid extends MovieClip {
[Code].....
when i execute it i am getting the error:
1136: Incorrect number of arguments. Expected 0.
This is at line 7 where it is creating the airplane object.

I have a series values I'm passing (from an FLA) into the constructor of a class. I just want to make clear in my mind that, the only way to pass the variable params, to the function nowDoThis, you'll need a dispatchEvent or a custom event to send it along ?
As an example:
Code:
// constructor
public function MyFunction(_param1:uint, _param2:uint, _param3:uint) {
param1 = _param1;
param2 = _param2;
[Code].....
I have only a vague understanding of using objects and dispatch events. Isn't this something that people need to do all the time?

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'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.

I'm used to building applications using pure AS3. I always pass dependencies into the constructor of classes I make, but this method seems to not work out well for Flex MXML views. It seems like I should define setters on the MXML class, which map to attributes in the tag/class instantiation. But using this method I cannot specify which properties are required and in what order I expect them etc. What is the preferred method to give a Flex view it's dependencies?

I need to dynamically pass 2 parameter to an swf movie to make it work properly, they are a number and a boolean. To do this I've changed the html page which contains the movie to php, I pass to the page the parameters' values through GET. The values are correctly passed to the page, I've tried to print them.
I build the call to the swf in this way collpreloader.swf?connid=<?php echo $_GET['connid'] ?>&animazione=<?php echo $_GET['animazione'] ?>
collpreloader.swf correctly reads the connid parameter, but animazione results always true.

So I have an MC that has 6 labels and 6 buttons all with different names. When you click on a button, it needs to direct you to it's appropriate frame label in the MC. Now, since AS 3.0 has done away with inline functions, how the heck do I code it so I don't have a function with a bunch of if statements inside of it in addition to all of my eventListeners that I have to add to each of my buttons? In AS 2.0, I would have done it like so:
Code:
function movePlayhead(whichOne:String):Void{
this.gotoAndStop(whichOne);
} button1_mc.onRelease = function():Void{
movePlayhead("label1");
};
button2_mc.onRelease = function():Void{
movePlayhead("label2");
};
Etc...
With AS 3.0, you have to add eventListeners to each of your buttons where each eventListener calls a function, but how can I write it so I don't have to write a bunch of if statements inside the function the eventListeners are calling in order to test for which button is being clicked? Like so:
Code:
button1_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button2_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button3_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
function movePlayHead(event:MouseEvent):void {

What I want to do is to pass parameters from the browser to flash. I searched and seems like the best way is FlashVars. However, I have tried different codes and can't get Flash to detect the parameters. I decided to follow the example here and just copy and paste the whole thing (just changing the "main.swf" to my swf name): [URL]. The flash loads, but it only shows "param:" without anything else. I gathered that it probably is a more fundamental problem. (e.g. the way I am debugging, or some settings, etc.) I am using CS4 trial version AS3.

I want to open a .swf file with a parameter for instance test.swf?beer=good and set "good" (the "good" parameter is going to constantly change) as a variable in the script so that I can add it to the stage in the swf file. The problem is I can't seem to figure out how to read the parameter so that it can be placed in the script.
For instance I have it set to:
var beer = "";
on (release) {
getURL("http://www.google.com/search?&q="+ beer , "_self");
}
