For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)

View 1 RepliesI'm passing a DisplayObject to a command that will instantiate it. Something like this:
// ViewClass is passed into this method typed as a Class
var view : DisplayObject = new ViewClass() as DisplayObject;
Is there a way to pass arguments to ViewClass() without knowing it's type? I'm assuming the list of parameters passed to any object's constructor is an array, but I'm not certain how to proceed.
I know I can do something like this:
// Assume arguments, an Array of arguments, has also been passed in
var view : DisplayObject = new ViewClass(arguments[0], arguments[1], arguments[2], arguments[3], arguments[4]) as DisplayObject;
But clearly I'd like something more dynamic, like to be able to just pass the arguments Array directly. I suppose all of this, however, goes against any type safe checking
Is it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip {
public function CustomRectangle(width:int, height:int) {
this.width = width;
this.height = height;
}
}
I know what instance variables, contractor methods, local variables and constructor arguments are (I think) but I'm confused as to when or how to use them, for instance I have use this a lot and I don't really understand why it is used like this...
[AS] package standard.testing {
import flash.display.MovieClip;
import flash.events.Event;
import com.greensock.*;
[code]....
Why create a function with arguments...
[AS]public function tweenMe(mc:MovieClip, xPos:Number, yPos:Number)[/AS]
Then create instance variables...
[AS]
public var _mc = MovieClip;
public var _xPos= Number;
public var _yPos = Number
[/AS]
then create local variables with the values of the arguments
[AS]
_mc = mc;
_yPos = yPos;
_xPos = xPos;[/AS]
I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so:[code]That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better:[code]

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.

View 2 Repliesi came across this problem and i have no clue why it's happening. basically, consider 2 nested movieclips on the stage, something like stage -> main -> filler. both movieclips have instance names (main and filler).
[Code].....
this throws an error 1119: Access of possibly undefined property filler through a reference with static type A. can anyone give me a hint on that, as it works with class A, but not B extending A? i understand it was meant to work?
I have a bunch of movieclips( clip A and B for this example) in my library that I want to use the same base class (MyClass.as in my example). I assigned the same base class in each clips property window and then gave each clip a unique class name which doesn't exist so flash says it will create the class automatically.
Now if I create a bunch of A's and B's on the stage via actionscript, how would I send variables to the constructor in MyClass.as without having to creating A.as and B.as to pass the variables along to the base class? if I do: Var newA:MovieClip = new A (argument 1, argument2, etc) It says it expects 0 args since the A & B classes were created automatically by flash.
when to use this in a classes?is there any specific rule?is it wrong to use this when you want to just access the stage that way?or is it better to pass the reference to the stage in the class constructor?

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'm having a weird behaviour with some some classes that I'm making. It seems that the Boolean values from arguments get changed on the way. I have two classes. On is called Carousel and the other Activity. The Carousel main task is to instantiate several Activity objects and place them in a way that resembles a carousel. This part is done, but there's a problem passing arguments from Carousel to Activity. Some data to instantiate the Activity come from an XML file. The XML resembles something like this:

I'm making a game in action script 3. In it, I have an actor class from which player and enemy classes will be derived. I'm doing this so that unless I need to provide specific AI or fancy behavior (such as for bosses), I can just make a new clip in the library for each enemy without making an actionscript file.
However, I've run into a problem.
Whenever I try to pass arguments to the construction of an enemy (make it spawn with more health), I get error 1136 (Incorrect number of arguments.)
This is because the constructor created automatically at runtime doesn't have the same arguments as it's parent class. Is there any way to get around this without making a class file where I copy and paste the parent constructor function for each of my hundreds of enemies?
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?
