ActionScript 3.0 :: Array Syntax Object Reference In Loop Takes 4 Seconds To Run?

Nov 9, 2010

Can anyone tell me why the following is taking 4 seconds for Flash to execute:
 
_moleHoles = new Array();
var countingMoleHoles:Boolean   = true;
var holeCount:int               = 0;

[Code].....

There are 9 object on the stage (but this number could go up or down, that is why I'm dynamically grabbing these this way). So in my test case, this loop runs 10 times.
 
I have narrowed it down to something to do with the following line:
 
if (this['moleHole' + holeCount])
 
Is using dynamic (array syntax) object lookup that much of a performance hit?

var myData = new Array();

What is the syntax to loop through and get the key and value? I have tried for each and for in but they just give me the value of "John" or "35", how can I get the key e.g. "Name" and "Age"?

ActionScript 2.0 :: How To Loop & Array Syntax

Sep 7, 2006

I've got this loop and can't get it to work. It won't read the trace so I know the array call in my function statement is wrong but I can't see it at the moment. What am I doing wrong here? The rollover works when I write it out repetitively for the four buttons.

var btnAction:Array = new Array (oneBut, twoBut, threeBut, fourBut);
for (var i=0; i<btnAction.length; i++) {
this.menuMC.btnAction[i].onRollOver = this.menuMC.btnAction[i].onDragOver = function() {

Flex :: NavigateToURL() Takes About 3-5+ Seconds?

May 29, 2009

My flex app has a call in it to navigateToURL(new URLRequest(_rURL),'_self');

But it takes about 3-5 or even more seconds before it will leave the current page.

If I omit the '_self' the new window opens immediately and the page loads immediate...but only when I set it to _self I get a few seconds of a delay before it loads...I have no idea why but it is annoying.. I am wondering if anyone might have any idea why this is happening or anything I can do?

Media Server :: RTMPT Takes 20-25 Seconds For A Response?

Mar 14, 2011

I am trying to connect to the Flash media servers from behind a customer's firewall.From behind this firewall the time taken for a response (its usually success) is around 20-25 seconds.The following is the code I am using to make the connection and listen to the events

var nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
var time1:String = (new Date()).toTimeString();[code]........

The delay between time1 and time2 is always 20-25 seconds. From other firewalls and non firewalled networks its usually 3-4 seconds.What could be the reason for this huge delay for a response in this case. I have noticed that the first response is always a "NetConnection. Connect.Success".We are looking to deploy around 20-30 media servers if we can get this thing to work and appreciate any prompt response in this regard.

ActionScript 2.0 :: Can't Reference A Movie Clip Array Via For Loop

Feb 1, 2007

I have this problem since many weeks ago, I can't figure out how to resolve it. My partial code is:

function checkCollision(rect) {
for(j=0; j < drop.length; j++) {
temp2 = eval(drop[j]);

[Code].....

I send to the function a movie clip that I use for drag and drop, so when I drop this function is called. The problem is that of the three rectangles that I use for contain the others, only the last senses the drop target.

Flash :: Reference Array Elements Of Class Inside For Loop?

Nov 13, 2011

I'm working with Flash Builder 4.5 on an Actionscript project. I've created the following classes:

package
{
public class ComplexNumber
{

[Code]....

but the code inside this loop generates the following run time error: "ReferenceError: Error #1056: Cannot create property 0 on ComplexArray." Thus, my code for "BXFN_complex[ii] = ~" is incorrect. Anyone know how to achieve what I'm trying to do? Basically, ComplexDivide.v1p0 returns two numbers, and BXFN_complex is an object containing two number arrays, and I want to assign the ComplexDivide two numbers into the ii'th element of arrays in BXFN_complex.

ActionScript 2.0 :: Get Copy Of Object In Array NOT Reference?

Feb 6, 2007

In the code below, i create an object and stick it in an array, then I make a duplicate of that array. I loop though the duplicate and change the value of one of the props of the object in the duplicated array. Doing this however unintentionally changes the prop value of an object in the original array. I'm assuming that the objects in the duplicated array are mere references to the objects in the original array. Is this correct? And if so, how do i make unique copies of those objects in the original array, so that changes made to the objects in the new, duplicated array are exclusive to those objects?

I know that i could probably make a new object when duplicating the array, and then recreate each prop, assigning values from the original objects.. but this is a simplified example. The project im working on has many props for each object, so, id rather just make copies if at all possible.

Code:
var testObj:Object = new Object();
testObj.prop1 = "hello";
//
var testArr:Array = new Array();

ActionScript 3.0 :: Adding Objects To Array - Null Object Reference

Apr 1, 2009

I'm having trouble with my code. I keep getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Test_fla::MainTimeline/frame1()
I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.

stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true);
for(var i:uint=0; i < numParticles; i++){
var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250);
addChild(p);
particles.push(p);
} function onLoop(evt:Event):void {
//for(var i:uint=0; i < numParticles; i++){
//particles[i].gravitate(1,1);
//}}

ActionScript 2.0 :: Syntax With For Loop?

Dec 15, 2005

I've got a for loop and some fuctions working, but can't get one line of code to work. The red line below is what I'm having a hard time with. I'm calling a function called "moveit". If I insert moveit(x1, y1); then it works, and my movieclip is moved to the x and y positions that I specified for item #1. Though I want it to work for 10 items (I only have coordinates for two here, and will add the rest later).

I've searched my ActionScript book and just can't figure out what the syntax should be for calling that function.

ActionScript 2.0 :: Replacing Multiple Statements With A Loop - Syntax Incorrect?

Jun 30, 2009

I have a series of images loaded in via XML and assigned to "loady" movieclips. This code works fine:

Code:

_root.myMCL.loadClip(_root.myImages[0].attributes.url,_root.loady0);
_root.myMCL.loadClip(_root.myImages[1].attributes.url,_root.loady1);
_root.myMCL.loadClip(_root.myImages[2].attributes.url,_root.loady2);
_root.myMCL.loadClip(_root.myImages[3].attributes.url,_root.loady3);

[code]...

I want to replace this with a loop since I know the total amount of items (myImagesNo), but this isn't working:

Code:

for (i=0; i<_root.myImagesNo; i++) {
_root.myMCL.loadClip(_root.myImages[i].attributes.url,this["_root.loady" + i]);
}
