ActionScript 3.0 :: Change Same Variable In All Class Instances?
Feb 12, 2011
i've made a Tile-class where i set "buttonMode = false" for each instance. I have been able to test that the value can be change from the main AS.-file, so this part works.
Code:
package
{
import flash.display.MovieClip;
[Code]....
This does change "buttonMode" but only on the very last instance. So this is where i'm at a loss -- i thought you could change all instances with one command like this but apparently not?

I have a button class and I made 3 instances of that button class as.. btn1, btn2 and btn3 Is it possible for the btns to share a global variable or something? For instance what I am trying to do. if btn1 is pressed it triggers a global variable "isClick = true" and if I click on a different button (btn2 or btn3) it checks to see if isClick is true then it calls a function A if not then calls different function B.

I am creating multiple instances of a movie class with the same variable name. The movie is then added random on the stage with a tween. On a mouse handler click, i want to remove the movie from the stage.
I am getting error -
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display:isplayObjectContainer/removeChild()
at Untitled_fla::MainTimeline/removeBlock()
Code:
import gs.TweenLite;
import flash.utils.*;
var block:block_mc;
var myTimer:Timer = new Timer(1000, 15);
myTimer.start();

How do I listen from the main class to a sub class for a variable change?
package {
import flash.events.*
public class DataBase extends MovieClip {
[Code].....
This is what I have so far for the sub class but I can't seem to figure out how to listen to this variable change from Main() or even if I am dispatching the event properly.

I've done a search on this and I can't find anything that makes sense
Its the first time I've created a document class and an object class that extends a movieclip. I've tried endless functions and properties to access the public function within the object class, but I'm getting lots of different errors. Both classes are within the same folder as the .fla file. I don't know what I'm doing wrong.[code]...

I have a simple problem. I have two document classes. One is Main.as the other is Step2.as. I want to declare a public variable in Main.as then need to give it a value from Step2.as. That value will later be used in my next Document class Step3.as How would I write the code that gives the value in my Step2.as and then how would I write the code that retrieves the value in my Step3.as?
Note I can't import my Step2/ or Step3 document class into my Main.as.

I want to know how to make class instances into listeners and broadcasters, from inside each class. Here is what I am trying specifically... part of the Proj class... (projectiles, as a matter of fact)
Code:
private function listen():Void {
u.register(this);
onUpdate = function(){
step(); // a function I have which makes the projectile move (not shown)
}
}
where "u" is another class, the Updater class with this code...
Code:
class Updater {
// const. --- make this a broadcaster
public function Updater(){
[code]....
PS: What is the syntax for using AS2 code tags instead of just "[CODE|"?

I'm slightly new to Flash CS3 + AS3 combo, so its more of a lack of practice question. My question stems from the problem described here http:[url].... . Note, its not the same problem, its a new one.The Problem ,So I have multiple library assets (which are on teh stage) and I want to assign similar functionality to all of them.
Attempt 1: So I create the n assets, create a custom class in AS3, link them to Flash CS3 and obviously enough it gives me the error that multiple assets can't be linked to the same class.Obvious enough to understand (well not completely, because from a programmers background it doesn't make sense).
Attempt 2: Same as attempt 1, but instead of linking all the assets to the same class I make the base class the same class, and let the derived class be dynamically created by Flash on compile time.So the linking works, but the problem is, in my base class I have a method which does something (say an tween) on a child of the library asset. So if the assets on the stage/library are called asset1, asset2, asset3 (same name for asset name, class name, id name), each of them has a sub-movieclip called ... say 'foo'. now if I manually wrote a class for each asset, I could do 'this.foo' to play with the sub-movieclip. However since this functionality is in the parent class, I'm unable to do it.
P.S. If you're form a programming/OOP background, its basically a abstract class problem. My Base class knows how to doSomething(), but it needs aSomething, which is defined in the Derived classes. However I found out that AS3 classes don't support virtual(C++ )/abstract (Java) in the true sense of the word (unless I missed some obvious documentation).

Let's say i have a bunch of balls/cells. I'm having trouble figuring out how to make it so that every other ball bounces off of every other ball.
so in short, it's really one instance being able to check all other instances of the same ball class?

I've been hitting dead ends while programming lately all over, and I finally came to the realization all the code I have that is broken is because I don't know how to interact with instances of one class from within another. Here's the gist of what I am trying to do:
if(this.hitTestObject(targetClip)){
trace("hit!");
}
The problem is, if I address a single instance that is on the canvas, I get "access to undefined property targetClip", even though the document class can interact with it fine. If I target the class file of targetClip, I get "Implicit coercion of a value of type Class to an unrelated type flash.display:DisplayObject". It isn't just a problem with hitTest either, I'm having this problem with other actions, so there is some basic syntax I'm failing to comprehend.

Im Have a function which is called after n ms and in this function I have code to change a movieclip to visible. I have 10 different movieclips with instances named n1, n2, n3 etc So everytime I call this function I want the next movieclip made visible.
So the code I'v been trying to use is this -
ActionScript Code:
function startNoFX(eventArgs:TimerEvent){
i++;
n+i.visible = true;// where i will corespon to the number giving n1, n2 etc
}
Im sure I'v seen something similar like this done before, I know I could write code for each individual Movieclip but I want to keep it tight.

Is there a way to group a bunch of movie clip instances into a single variable? Reason is, I have a lot of movie clips acting as buttons that I have added to event listeners. All of the movie clips with do the same functions and I have a few different functions created.
For example. How can I change this
Code:
mc_aitkin.addEventListener(Event.CHANGE, changeAlpha);
mc_anoka.addEventListener(Event.COMPLETE, changeAlpha);
mc_aitkin.addEventListener(MouseEvent.MOUSE_OVER,hoverOver);
mc_anoka.addEventListener(MouseEvent.MOUSE_OVER,hoverOver);

Is it possible to create 2 instances of 1 class (for example: "Header"). Add these 2 instances to the stage on different positions. This Header class contains some buttons and what I want, is: when I rollOver one of these buttons, both buttons in the 2 Header instances are "rollingOver".

I have a piece of code, that moves an array depending on it's type. If the array is of TypeA objects, it will change TypeA. If it is TypeB it will change TypeB. The issue with the current code is the repeative blocks.

Which stops working whenever I need to access any property (user) selectedInstance.testSomething();

I need to get all the instances in my stage according to an especific class name. I'm doing this:
var class_ref:Class = getDefinitionByName('fran.MyOwnClass') as Class;
var element;
for (var i:uint = 0; i < this.parent.numChildren; i++)
{

But I want a better way (more efficiently, without checking all the MCs).

I recently learned how to use gravity so I made a bouncing balls program but I have an issue with the interaction between the frame timeline code and the class.The problem is that when I create instances with a timer, I declare the variable inside the timer function. And I want to add a blackhole sort of thing when I click down on the stage but I cannot access the object from the blackhole function since it's declared inside the timer.

my probem is that i need to find a way to control them after i created them.

I got a ton of movieclips in a class. Is there a more efficient way to apply a function to every instance in the class other than this?
var textArray:Array = [
interludes.interludeIntro.interludeBegin1,
interludes.interludeIntro.interludeBegin2,
[Code]....
I have NO idea why the above doesn't work. I want to turn every single instance in the class interludeIntro invisible, but I want to turn specific instances visible later.
how to insert code on this website, pressing "code" doesn't do anything, so pardon the bad formatting)

Let's say I have created a class named Store. This class has several elements such as Name, PhoneNumber, Owner. I've created 2 instances of this class and want to know which values are different. So lets say that Store1 and Store2 are instances of this class.
Store1.Name = "John's Corner";
Store1.PhoneNumber = 111222333;
Store1.Owner = "John";
Store2.Name = "John's Corner";
Store2.PhoneNumber = 444555666;
Store2.Owner = "John";
[Code]...
Is there a way to automatically loop through all elements of a class instance and compare them to the same element in another class instance and return something when they differ?
This might be obvious but I can't figure it out.

I'm new to this OOP stuff, and I'm having a hard time understanding all of this.I'm trying to recreate in AS3.0 with classes a simple whack-a-mole game I created in AS2.0 using timeline coding.I've read through a lot of forums, but I still don't understand what exactly I'm doing wrong.Heres my setup:I have a movie clip named mrBunny (my girlfriend told me to change it to bunnies as moles were too ugly.). Now there are 6 instances of mrBunny on the stage, each named mrBunny0-5.The mrBunny symbol is linked to the com.mrBunny class.The class has a method called randomPlay(); which I use to randomize the animation times of mrBunny.I also have a button on the stage with the class stageBtn.
package com{
import flash.display.SimpleButton;

I am making an AS 2.0 Class for polygons called "Shapes2". Shape2 is basically an array of Vectors (another Class I made) and is built using the function addPoint(x1,y1) to build the shape from a series of points. The points are then converted to vector-edges, etc etc.Here's the long and complicated construction:
Code:
var pent:Shape2 = new Shape2();
var rect:Shape2 = new Shape2();
if I comment out either instance, the other is functional when I test it. Trying to do two instances makes rect and pent point to the same array of vectors, but they keep other variables and properties separate, which means rect isn't just pointing directly to pent or visa versa.
