Is it possible to rename a class-instance that has already been created with a specific name?For instance:
// Step 1) Create and name class-instance
var myClassInstance_1:myClass= new myClass();
// Step 2) Change name of myClassInstance_1

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 have an AS3 based FLA that, for various reasons, needs nearly all of the linkages in the library reworked (need to move to a different package namespace).This particular FLA is pretty big, so doing this by hand would be rather tedious.I have considered saving out the FLA as an XFL, and just hand editing all of the XML files in the LIBRARY folder, and then saving out as FLA. Has anyone tried this? I have never worked with XFL files before, so I don't know what quirks I may run across.My problem has to do with loading SWFs and class conflicts because of multiple SWFs using the same package namespace. Without getting into too many details, I know about ApplicationDomain and LoaderContext. I am currently loading into a new ApplicationDomain, but that isn't an ideal situation and is causing grief that won't be maintainable in the long run.
View 1 RepliesI am trying to build an uploader that will take data collected earlier in the form before the upload occurs and then rename the uploaded file with it. I've gotten the upload itself to work, but thus far I have no luck getting any sort of renaming to work, not even by PHP.I tried Loadvars to transfer the variables over and rename it during upload, yet it says "NO" and rejects the post variables when the upload occurs. I even tried loading the variables into an external file and transfering them back to the uploader via cookie, all at the same time. Again it says "NO!", and the file is uploaded as __"filename".jpg. This is my code thus far:

The problem I'm having is when I goto .push the array it combines the strings instead of calling the imageCount variable with the correct number attached. Can anyone think of a technique to work around this or some where I can look to get an id.

View 2 RepliesSo I have an AS3 flash project with A LOT of assets, roughly 1000 at the time being but that may expand to several thousand later. They are all images but half of them are Animated GIFs so I can't import them at runtime. I considered simply dragging them into the flash project but I don't seem to have any control over the naming scheme. Basically, what I want to know is:
Is there a way to automate importing and renaming of flash assets, like "Import these 1000 files and export them for Actionscript with this name"? Additionally, is there a better way for me to be doing this? I've tried [URL].. AS3GIF but it struggles with larger animated gifs like the ones I'm working with (650x450).
I have an application already created that will upload files successfully, with a progress bar and completion notices and am very happy with the process, but sometimes people upload a file with the same name as an existing file. Is there a way to change the name of the destination file on my server to something more standard during the upload process? I have been using a fileReference.Browse() with capturing all my event handlers through there.
View 4 RepliesIs 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".
View 1 RepliesI 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.

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.

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;
import flash.display.MovieClip;

this's been bugging me, anyone know what's wrong?
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:

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 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.

When I trace the value of siteStructureXml from within the class instance it shows the expected xml data.

I'm writing a series of Search windows for an application. I create the FLA files on the stage, each has 3 simple buttons: next_btn, prev_btn, and close_btn. Those all have event listeners which call findNext(), findPrev() and closeWin() respectively. Each search window looks for different things, some with a text box and some with a combo, etc.
So I have a base class com.search that extends Sprite and adds the eventListeners at startup (actually, on addedToStage). Like this:
function isAddedToStage(evt:Event){
next_btn.addEventListener("click",findNext); prev_btn.addEventListener("click",findPrev); close_btn.addEventListener("click",closeWin);}
[Code]....
If I add the event listeners in the derived class rather than the base, it works fine. But that seems to defeat the purpose of inheritance, plus it infers that I won't be able to derive new classes/swfs from those derived classes.
