Actionscript 3 :: Differences Between Variable Instantiation Outside Constructor And In?
Dec 19, 2010
I found two difference that I feel might be important:
-If I decide to put the variables within a constructor, then I must have an object parameter for any function that wish to alter the variables, even if the code is internal to the class.
-Subclassing would cause the variables to not appear, something that causes problems when the class and any subclasses must have the variables in order to operate properly.

I wrote a script to make a random image from an array appear and float up through the stage. The problem is that at some random time in the movie, i get the error: TypeError: Error #1007: Instantiation attempted on a non-constructor. at Untitled_fla::MainTimeline/enterFrame() This occurs at random intervals. From that point on, the script stops working. There must be something wrong with the way I generate MCs from the array.[Code]...

I am just trying to explore flash by my own little cognitive thinking..
import flash.events.Event;
var slot:Array = new Array(26);
var letters:Array = ['a','b','c','d','e','f','g','h','i','j','k','l','m ','n','o','p','q','r','s','t','u','v','w','x1','y1 ','z1',"hypen"];
var posx:Number = 125.5;
var posy:Number = -47;
[Code] .....
And the error is pointing in this line of codes:
this[getChildByName(letters[rand]+counter)] = new this["mc_"+(letters[rand])];

I have an image gallery with thumbnails and a previous button and next button. "nextPrevPosition:Number" starts out with the value of 0 and increases or decreases by 1 every-time the previous or next buttons are pressed. The thumbnails assign a value when those are pressed:
Quote:
private var nextPrevPosition:Number = 0;
private var currentPort:MovieClip;
private var POSITION:Array;
[Code].....
all works fine except when NextPrevPosition reaches the original value 0...and this is when I get the error message. It looks like the line "currentPort = new(POSITION[nextPrevPosition] as Class)(); is when it is happening.

what i'm trying to do is get a movie to duplicate movieclips when the original movieclip is dropped onto a target.what it does is,
1. click, drag movie clip to target.
2. drop, released.
3. duplicate movieclip appears in the ORIGINAL position from where the original movieclip was picked up.
4. and keep the dropped movieclip in place.
i don't know why i get,
TypeError: Error #1007: Instantiation attempted on a non-constructor. at Untitled_fla::MainTimeline/dirt_UP()
Code:
function dirt_UP(e:MouseEvent):void{
if (e.target.dropTarget != null && e.target.dropTarget.parent == this.shirt){ e.target.stopDrag();
startX = e.target.x;
startY = e.target.y;

Possible Duplicate: Where is the "proper" place to initialize class variables in AS3
Whether its better to instantiate class on it's variable declaration or within a constructor? For example, this:
protected var _errorHandler:ErrorHandler = new ErrorHandler();
or this:
protected var _errorHandler:ErrorHandler;
public function someClass() {
_errorHandler = new ErrorHandler();
}

I recently learned beginner grade skills for AS2 via Macromedia Flash. it had only AS2 so i thought i'd be good to programin that.well i completed my project (a minigame for a bigger game was the first time i programmed ever actually. Was really fun and you can find my "work" in the attachment) changing to adobe flash on the way its what the workstations in my u have. well i there saw actionscript 3 too. also, sometimes when i asked for help on here they told my i "should switch to as3" soon. now im about to work myself into as3 but first I'd like to know.what are the main differences and could someone show me a code in AS2 and the same code in AS3 or link me to a tutorial that makes good use of AS3 (possibily by using AS2 references to clarify the structures?)?why is As3 "better" than AS2?

I used Jamie Durrant's tutorial for making a chat bot in flash. Everything works fine, but one thing which makes the bot remember people works only if the fla file is published in Flash Player 6 version. There are 4 symbols: a button, user, reply and custid: user is the textbox where the user inbuts the text, reply is the textbox that displays the bot's reply and custid displays the id of each person. If the version is newer than flash player 6 it says "undefined". It's a local shared object, I think. Could this code be edited to work in later versions or I have to stick with flash player 6 (the graphics are worse even at lossless compression)[code]

We have lots of log information (syslogs, database logs...etc) which is in CSV format. I need to present this information to key management about the activiites from the logs in Visual format but still has dynamic links. For the management sake, I need this application to be cross platform (Windows, MacOSX, Linux).What tool do I need to use Flash, Flex or (something else like Java)?

I have created a flash 3d racing game which relies heavily on AS3's Math functions (sin, cos, tan, asin, acos, atan). It also makes heavy use of Matrix3D and Vector3D functions. The game works great on a PC, but the cars flip around and display innacurate positions on Mac computers. I know this is an issue due to the note on the Math docs page: [URL]
which states: "Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use."
how do I get this game to work on a Mac? I've tried using lookup tables and inline FastMath style approximations. But lookup tables still create the same problem, and the inline approximations I have found are not accurate enough for my game. I've also tried rounding values with floating point errors, but that has not seemed to help (in my implementation) either. I think the specific problem is with the use of Math.atan. I have not found an accurate approximation for this.. but I maybe that is not even necessary.

I have two text boxes on the same window. They are both set to Arial 14 Regular but they both appear very differently. To see what I am referring to: [URL] and go to the Conversion Tools at the bottom of the page. Click on Surface Finish and type in a value in the two different fields and click calculate. I really don't see anything that could be causing this difference in appearance.

I'm currently upgrading an app from Flex 4.1 to 4.5.We've noticed that the Arial font is rendered differently between the two versions when used at small sizes.Here's a simple app example:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"[code]....
When run against the 2 different sdks, here's an image of the font rendering we get:
Note that in 4.5 the font looks slightly squashed.
What's the cause of this, and how do we resolve it?
