ActionScript 3.0 :: Create Globally-accessible Class Instances?
Jan 25, 2009
I created a custom class (no arguments needed for constructor) and I wanted to create an instance of that class that can be accessed by AS from aywhere inside the SWF (i.e. globally from any function or class).So far the only way I can think of doing that is to create the custom class with an associated MovieClip Symbol, drag an instance of that MovieClip Symbol to the stage, and then give it an instance name. It seems like I can then use the instance name to access that class instance anywhere.

I am working on a very simple game in Flash. I want to make all the animations framerate agnostic, so that I can change the framerate without affecting the flow and speed of the game.I read somewhere that if you want to do that, you simply create a Timer object and attach an event listener to this timer.
What if I have many objects that have to listen to the same timer? See the code to understand what I am trying to do. At this stage nothing breaks, but the event does not fire.Here is the Main class, the one that runs on swf execution:
public class Main extends MovieClip {
private static var _stage:Stage;
private static var _timer:Timer;
[code]....

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.

I create 3 instances of the class below. I need to find a way to call them with a delay so they get added to the stage one after the other. Is there a class that lets me queue up functions? Or an economical way to do it with the functions built into flash.

Exactly this doesn't work but is there a way to do it?
Code:
for ( var i = 0; i < 10; i++ )
{
var ["object"+i]:MyClass = new MyClass();
// would create object1, object2, object 3, object 4, ...
}

Assume I know practically nothing about AS3! I'm using Flash Pro CS5. I'm trying to reassociate a flash file I've been given with its external assets and classes. In the library I have a movieclip with linkage to a class called 'StaticMap' using the base class 'flash.display.MovieClip'. am I missing a custom class file called 'StaticMap.as' that was originally located in the same folder as the fla, or is this a generic class accessible to all movieClips from within Flash?

I have a project in ActionScript 3, Flash Professional CS5.5, and AIR 3. I have several custom classes that I need to access. Currently, I am successfully accessing via the traditional method:
import trailcrest.core.core;
var Core:core = new core();
However, I came to a realization in my code...this creates a COPY of the class, and doesn't give access to the original. This, of course is a problem - I need one symbol's scripts to modify a variable in the class, and another symbol's scripts access that changed variable. Obviously, right now, that is not occurring.How do I do what I am describing? Should I somehow create a "public var" for the class (though I need instructions on how to do that...I can't use "public var" within stages or symbols)? Is there some way to directly access the class?

I am creating a custom Flash component with AS3. My component's main class imports a class with a static variable. How can I make this class accessible by the user of my component from a flash-level? This is the example:
my component's main class:
package
{
import flash.display.MovieClip;
import MyStaticClass;
[Code]....
The thing is I don't want to provide the user with the MyStaticClass source. I would like it to be automatically imported and accessible after dragging the component to the stage.

I am trying to make a class that extends the movie clip class. I want to essentially have a movie clip class that has a "handle" by which I mean a settable reg point by referring to a parent container movie clip. I have many parts of it working. I have functions that can move the handle/parent to any location on the screen, one that centers, and a move method that moves the movie clip by moving the parent so it is being moved by the origin you specify etc.
But one thing I would like to have the handledMovieClip class to do is to make the handled movie clip and then automatically generate the parent movie clip with the same name appended with "h" and put the handledMovieClip into the parent MovieClip. The parent movie clip should then be accessible by actions on the main timeline. Suppose that the movieclip name is MC so then the parent would be called MCh. I do this by making a new movie clip and then changing the name to "MCh".
But when I try to use the dot syntax from the main time-line it doesn't seem to know the object. So I can't do something like "trace(MCh.width);". I can get what I want by creating the handled movie clip and then the parent and then putting the handledMovieClip into the parent with addChild. It works if I do it from the main time line, but not if I try to do the exact same thing within the class constructor. I thought it would be a nice feature if the user only had to make the handledMovieClip and if the parent was generated by the class constructor automatically.

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 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(){

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.

I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

My project downloads an array from a MySQL server that has URLs for pictures in it. Part of my script then downloads these pictures and splices the array (removing the URL and replacing it with the bitmap). Now i need to use those bitmaps on the stage but i need two instances of the same bitmap at the same time, and it seems like flash is having a problem with this.
How do i create two instances of the same array bitmap?

For example if I wanted to do something like make a function which is used to spawn multiple instances of an enemy movie clip.[code]do this a specified number of times.How would I go about doing something like this? And what is the syntax for referring to these generated movie clips from outside of the movie clip (so i could do things like remove them, change x/y,alpha, ect, individually)I really just don't have an intuition for how movie clips actually work in actionscript, and its been holding me back a great deal.

I'm running into a roadblock with creating multiple instances of a movie clip. I'm trying to display a series of boxes across the bottom of the stage. The number of boxes are determined by _global.maxStep[_global.sectionNum]. I have a movie clip called StepBox that will serve as the template for each box. In the StepBox movie clip is a dynamic text box called stepNumText, which I want to set to the value of the counter. The problem I have is that I've only ever used attachMovie, but there is no movie for it to attach to. I tried using Content since that's the name of the layer this is in, but I know that doesn't make sense (and it doesn't work).
Code:
_global.updateBoxes = function() {
var curr_box;
for (i = 1; i <= _global.maxStep[_global.sectionNum]; i++) {[code].....
