ActionScript 3.0 :: Can't Set Properties From Instances Of Class?
Jun 9, 2011
I have a class - call it MyClass - and an instance of that class with instance name myObject.In MyClass I declare:
public var myVariable:Number;
In the main timeline I try to set it using myObject.myVariable = 3;
In the main timeline, if I do a trace (myObject.myVariable) it will return 3. Within the class, if I do a trace of (this.myVariable) it returns null.However, if I add a line of code in my class and add this.myVariable = 3, it traces 3.Why can't I get myObject to correctly change its own parameters?

I've created a movie clip and placed it in the library. I've given it a class name via the properties panel in the library. Every time I drag it to stage I want to make sure its alpha is set to 0. If I drag 300 of those clips to stage, is there a way to reference the class name I gave it in order to automatically set the alpha value as soon as they're dragged into the stage?

I have a Hero that can shoot bullets. I can get him to shoot multiple bullets, all with equal velocity. The bullets are supposed to be peas from a pea shooter, so I want to apply friction and gravity to them so they slow down and fall. I'd also like them to bounce of objects too.At the moment I'm just applying friction, so the peas should be shot forward, and then gradually come to a halt in the air. The problem I'm having is that if I apply friction to one pea, it generates the next one at the velocity that the 1st one is currently at - that is, the second pea starts out slow, and stops very quickly. The 3rd one is generated not moving.
How can I set the velocity to reset for each pea, so they all start out equal? They all move with the same properties, so I want to deal with them all in one arrray/loop. Is this possible?I have posted the basic structure without any velocity or anything specified because I'm not sure where everything should go. If I specify a starting velocity in the document class and then use the for loop to apply friction, it changes the velocity of every pea. The Pea class just contains functions to draw the pea.
Code:
public function bullets(event:Event):void {
if (s==20 && PandaHero.currentFrame==13) {

I am using flash CS3 with ActionScript 3.0. Suppose, I created a button component and a Combo-box component. Hence, SWF file consists of a Button and a Combo-box component. Now, my requirement is, How to access the instances and properties of these components(Button and Combo-box), so that I can create HTML webpages depending upon the Combo-box selection and the Button click events occurred on flash components? Here, we need to pass/send the flash components' instances to HTML. How can we do it? All I want is to access the flash components in HTML.

I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.

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(){

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 have a class, call it MyClass, and there are several variables that I need to be able to access each instance of from within the class.So for instance, I need the object myObject1, a member of MyClass, to store the variable myNumber.From the main timeline, if I trace myObject1.myNumber, I get whatever number I've stored.
However, I need to check the numbers against another parameter, so I need to be able to test if myObject.myNumber == myOtherNumber. But from within the class, if I trace this.myNumber or myNumber I get null.What is the proper syntax for accessing a variable within a class?

I have an mc called sunny. In the properties panel I export her for actionscript. I put Sunny in the main class and Drag in the base class. The reason for this is that I want her to be draggable. I can't use Drag in the main class as another object is using that name. The Drag.as has the drag functionality. Why can't I drag her. I already have a solution - I wrote a specific class for her and extended the Drag class. However, if I have 10 mcs I'm not going to write specific classes for all of them. Summing up: Using the base class Drag in properties panel - why isn't she draggable?

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 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 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.

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.

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.

I have four instances of the same class called Tile, that is bound to a movieclip with four frames. They're imbedded in a movieclip that I'm using to hold all of the visuals.In the main class of my .fla I declare a variable called menu1 that is bound to another movieclip with 2 buttons on it.
I'm trying to make three things happen here: on clicking the Tiles the menu will pop up over the tile that was clicked; that on clicking another tile when the menu is already up it will close that one before adding a new one; and lastly, that on clicking the second button in the menu, it will change the frame of the tile clicked and close the menu.The tile.as has an addeventlistener in it's construction method to add the function onTileClick to each Tile.
public class Tile extends MovieClip{
public function Tile():void{
addEventListener(MouseEvent.CLICK, onTileClick);[code]....
This works fine for one tile. I can click on it, the menu pops up, I can close and reopen the menu as many times as I want, and I can use the other button with no problems.Also, clicking around on different tiles moves the menu around without repeatedly adding it, so that seems to be working fine as well.The problem is this: If I click on a tile, close the menu, then click on another tile and close it, I get an error 1009.It still closes, that error just comes up. And it will come up for any more tiles I open and close it on.Then, after clicking on however many tiles, if I do click the advance button, it affects all of the tiles, and I get an ArgumentError: Error #2025 for each tile clicked on.I tried adding a variable that held the event.target value in the onAdvance function, and using that for the gotoAndStop, but the same thing happened. When I tried tracing the name of the variable, I noticed that it was tracing the names of each tile clicked with each subsequent trace.
Am I building this all wrong?I thought that making a class for my tile object, and adding eventlisteners to the class, and adding the functionality of the tiles inside of the class would be good practice for Object Oriented Programming, but it seems to be producing nothing but errors. When I defined these tiles inside the main timeline, with separate event listeners, I didn't have this problem

I'm trying to make it so that the instances of the class "Enemy" stop completely when they get too close to each other. They are circles so determining a collision is easy. But when I used this code:
Code:
if (Math.sqrt(Math.pow(x-_root.newEnemy.x, 2)+Math.pow(y-_root.newEnemy.y, 2))<=width+3) {
canMove=false;
}

This code works just fine when I test it against the instance of a different class, but it's not working for some reason.

I have two movie clips on the stage at frame 1 and frame 2. Both are instances of seperate classes. (They are not dynamically created, just their linkage is set to their class names)I have created soundChannel and Sound Objects in Class 1 and I want to access them from Class 2. (I want to stop the sound channel that was started in class 1)Is there any way to do this? If yes, will this be true for other properties also?

I've been working on a project in Flash CS3 for a while. To follow an object on the screen and keep it centered, I'd adjust the Document Class' x and y properties.
Yesterday I bought/installed Flash CS5 and thus Flash Player 10 was also installed. Now when I go play my SWF it seems everything is all buggy, as if the code that modifies the Document Class' x and y properties isn't exactly working properly...
I've since reopened the CS3 FLA in CS5 and converted it to a CS5 format and I can't seem to get it working the way it used to.
Did something change regarding the Document Class and how to modify the x / y properties of it in the Flash Player 10 version? I really don't know what's going on at this point.

This is my code so far:

Ideally, I would like the squares to be added automatically, with increasing numbers and 100 x 100 pixels apart. Possibly a 'for-loop' statement?
