Global vars in as3

Hi all,
I'm sure this is easy, but I can't seem to find out how to do this. I need to create a global var in AS3 so that I can create the var on the main timeline and change it within another movie clip. Thanks for the help in advance.

If you design your program correctly there is rarely a need for global variables. That said, the easiest thing is to just make the variable a public member of the document class. Then any objects in the program can access this variable using "parent.myVar", etc. I generally like to pass the main DisplayObject in as a parameter of any instantiated class. That way I don't have to use "parent.parent" or any confusing syntax. You could also use "this.root" but I try to avoid that at all costs.

Global vars in as3 and code run order

two questions:
1)how can i declare a global variable in as3, like in as2 i
could write for example :
_global.variableName = "variableValue"
and then access the var from anywhere.
2)how can i tell a part of the code from the root to run only
after the code ran in all the other movieclips when the swf loads?
thx

As far as the first irem goes... AS3 does not support the
_global reference. Just Google "AS3 _global" and you can probably
find a few options. Here's one result:

Global variable in as3.0

I am doing something with flash cs3,I need to use global
variable in it ,but there is not global variable in as3.0,can
anyone help me ,thanks forever!

There is no global in AS3. But you can make values globally
accessible by
using static fields in classes. e.g.
// MyClass.as
package
public class MyClass
public static var globals = new Object();
MyClass.globals["hello"] = "world"
trace(MyClass.globals.hello);
// and if you want to simulate something a little
// closer to the AS2 _global object you can drop
// this into a top level in your class path
// global.as
package
public const global:Object = new Object();
global["hello"] = "world";
trace(global.world)

Get All Control Values [Variant] Method for Global Vars

Hello,
to get all the data of controls use in a VI, the methode "Get All Control Values [Variant]" can be used fine.
Is anything else available for gloabl variables which are use by this VI?
Thanks.

Yes, I tried to link this methode to the vi which contains the global vars but got the error message
"you cannot make a strict vi refernce to a global VIs.
Any other idea?
Thanks, Thomas.

How to debug global vars ??

I have a problem with the tcode iw32. sometimes the dates are not updated by the system if the main date is changed in a operation.
this happens with 1 out of 10.000 orders but the impact on the process is very frustrating since it's hardly noticed in time
now I have a serviceorder where the corresponding date FSAVD is not changed after changing NTANF.
I thought I had debugged to a point that I thought the function was were the dates were changed unfornatunatly I noticed that somewhere in the programm the global table AFVG_BT is filled. but I can't find where this table is updated in the programm SAPLCOIH ???
anybody knows how to find the source of the changes ??
kind regards
arthur de smidt

but it's not an update on a database table but on a global var. in st05 the runtime analysys you only see the database acces so I can't find how and when AFVG_BT is updated ?
also under se30 I can find a function which I already found before only then the global var is already updated by the system . I want to know when this global var is updated and what rules have been passed before this update took place
kind regards

Global Var in Bp

Hi Masters,
How can we create Global Var in BP?
I tested Co-relation, but could not get any easy way to use the concept of Global Var in BP.
I want to check that how many times my BP has been triggered?

All the variables are essentially global to the process. Creating a new variable of type xfaForm will do what you ask. If you add an Assign Task, there is a properties section for Form Data Mappings. If you set the input and output to the xfaFrom variable, then any changes made are applied to that variable. You can modify values with a Set Value step using xpath. It is best when you create the form, that you associate a schema with it. Having a schema associated with it with allow you to expand down to any element in the form/variable in the XPath Builder.

Is there a list of global vars somewhere i can access in apex

is there a list of global vars somewhere i can access in apex
also can i have the http address in a var in apex

Hi,
See the section on Substitution Strings here: http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10499/index.htm#S - this details the available global variables (eg, APP_USER).
You can define your own substitution strings - these are set on the Shared Components, Definition page - so you could put your url in there. There are other methods as well, such as Application Items or a SQL table (which may be better if you need to get the url value outside of an application)

How to collect returns from recursive function calls without a global var?

Usually global variables shouldnt be used, I was told. Ok. But:
How can I avoid using a global var when recursively using a function, when the function returns an object and when I want to have the collection of all these objects as the result?
For example, I think of determine the users of a group including group nesting. I would write a function that adds the direct group members to a collection as a global var and call itself recusively if a member is another group. This recursively called function
would do as well: Update the global var and if needed call itself.
I'm afraid this is no good programming style. What algorithm would be better, prettier? Please dont focus on the example, it is a more general question of how to do.
Thanks
Walter

I rarely needed to create/use recursive functions. Here's one example I did:
function New-SBSeed {
<#
.Synopsis
Function to create files for disk performance testing. Files will have random numbers as content.
File name will have 'Seed' prefix and .txt extension.
.Description
Function will start with the smallest seed file of 10KB, and end with the Seed file specified in the -SeedSize parameter.
Function will create seed files in order of magnitude starting with 10KB and ending with 'SeedSize'.
Files will be created in the current folder.
.Parameter SeedSize
Size of the largest seed file generated. Accepted values are:
10KB
100KB
1MB
10MB
100MB
1GB
10GB
100GB
1TB
.Example
New-SBSeed -SeedSize 10MB -Verbose
This example creates seed files starting from the smallest seed 10KB to the seed size specified in the -SeedSize parameter 10MB.
To see the output you can type in:
Get-ChildItem -Path .\ -Filter *Seed*
Sample output:
Mode LastWriteTime Length Name
-a--- 8/6/2014 8:26 AM 102544 Seed100KB.txt
-a--- 8/6/2014 8:26 AM 10254 Seed10KB.txt
-a--- 8/6/2014 8:39 AM 10254444 Seed10MB.txt

Change a Global var based on page

Can I change a global var based on what page I am on.
For example.

Hi,
I do that sort of thing myself - though usually I use this as a pointer to where I need to return to when the user has finished an action on a form page (the form being accessible from multiple pages).
Create an Application Item called, say, G_RETURN_PAGE.
On pages 2 and 3, create a Computation that runs Before Header and, using a Static Assignment, sets G_RETURN_PAGE to that page number.
In my case, I use &G_RETURN_PAGE. in the Page setting on a branch, but you could use :G_RETURN_PAGE in PL/SQL etc

Loading a text file into a global variable issue - really a global var?

From all the documentation and examples I can find, it appears that it would be
correct to create a global array variable [outside of any functions] to load image names into,
then use these images for a slideshow. I want to make the app dynamic, in that changing the text file gives a new set of images.
The global variable goes null [no values] after the load event listener. Why is that?
Isn't global, well global, and alive for the duration of the SWF?
PARAMS.TXT:
monthNames=January,February,March,April,May,June,July,August,September,October,November,De cember&dayNames=Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
CODE:
var dNames:Array = new Array();
var mNames:Array = new Array();
var request:URLRequest = new URLRequest("images/params.txt");
var variables:URLLoader = new URLLoader();
variables.dataFormat = URLLoaderDataFormat.VARIABLES;
variables.addEventListener(Event.COMPLETE, completeHandler);
try
variables.load(request);
catch (error:Error)
trace("Unable to load URL: " + error);
trace("2 mNames 2: " + mNames[2]);
trace("2 dNames 3: " + dNames[3]);
stop();
function completeHandler(event:Event):void
var loader:URLLoader = URLLoader(event.target);
dNames = loader.data.dayNames.split(",");
mNames = loader.data.monthNames.split(",");
trace(loader.data.dayNames);
trace("1 mNames 2: " + mNames[2]);
trace("1 dNames 3: " + dNames[3]);
OUTPUT:
2 mNames 2: undefined
2 dNames 3: undefined
Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
1 mNames 2: March
1 dNames 3: Wednesday
How do I access these values after loading from the external file, after the load?
Thanks in advance.

The statement you quoted from whatever Adobe documentation is correct.
If you want to load the data into the arrays before anything else happens, then have anything else that happens execute via the completeHandler function... after the data is loaded and processed into the arrays.
the command: loadFile() executes before the trace("2:" +images[4]); command. The loadFile function is processed and the loading process BEGINS... but starting the loading does not delay the main processing from continuing down the line--the loading itself becomes a secondary/background task. The command was to execute the loadFile function and the processing of that function was completed. If you don't believe so, then add a trace...
function loadFile():void
     vars.dataFormat = URLLoaderDataFormat.VARIABLES;
     vars.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
     vars.load(new URLRequest("images/fnames.txt"));
     trace("started loading");
If you add that trace, you should see that the loadFile function execution is completed and the next line in your code is then processed... trace(2....)
The addEventlistener does not stop anything. The addEventListener code is assigning a monitor, not a traffic controller... it is telling the monitor to indicate when the data has finished loading. It is not telling anything to stop program execution.
So if you want to wait until the data is loaded before you do anything else... it goes....
function onComplete(evt:Event):void
     var urlVars:URLVariables = evt.target.data;
     images = vars.data.images.split(",");
     tnails = vars.data.thumbnails.split(",");
     ................HERE.................

How to view global vars in debugger

I have a C array outside a function and now I can see the values of the array in the debugger window. I have the array outside the function because I need it to be global.
When I click the globals triangle it brings up a global browser with many different items in it but I don't see my array?
Thanks

Ok. I put my var in main but that didn't help.
I noticed my path string on the bottom of the global brower is very different from yours?
mine is:
/Users/user/Library/Application Support/iPhone Simulator/User/Applications/(a bunch of hex chars/My Button Fun.app/My Button Fun
I'm wondering if this is a clue why it's not working?
My actual path where my project is:
/user/xxx/xxx/xxx
I wasn't able to provide a visual snapshot. I guess I never added a pic on this board before.
Thanks

Parsing PHP Vars in AS3

I'm pulling in vars from a PHP file into AS3, which im very new at, and having a few general and what i assume easy questions:
first of all, my php looks like this:
<?php
$first="VARDATA";
echo "v1=$first";
?>
my question is, why can't i: echo"$first"
i have to: echo "v1=$first"
here's the actionscript pulling in the data, I assume there's a parsing issue perhaps??
var myLoader:URLLoader = new URLLoader();
myLoader.dataFormat = URLLoaderDataFormat.TEXT;
var myRequest:URLRequest=new URLRequest("thefile.php");
    myLoader.load(myRequest);
    myLoader.addEventListener(Event.COMPLETE,onCompleteHandler);
    var newValue: String;
    function onCompleteHandler(e:Event):void{
    var newvariable: URLVariables = new URLVariables(e.target.data);
    newValue = newvariable.values;

YOu can echo whatever you like, but chances are you don't want to quote the $first variable like you are doing.
The URLVariables class reads the data in name/value pairs (name=value), which is why you want to send v1=VARDATA

[JS] (CS3) GLOBAL var. Weird behaviour!

I have been working w/ a GLOBAL array defined in "session"
The array is being populated with WORD objects when running a checks abbreviations script. Each word skipped are added using the push function. You can view and zero out the array, using ANOTHER script. But when you close the document, if you try to view again the array, there is an error "undefined object". Actually the array exist, it has word objects but if you access one of the contents (ie: SkipWRDS[0].contents), you get an error! So it's kind of corrupted. Any idea?
Thank you, Alex.

If the array contains references to words in a document and you close that document then the document no longer exists and so neither do the words. So the error is no surprise.

Global vars

so i've been googling like crazy trying to figure out
something that of course was very simple in as2. I don't understand
classes, packages, etc. Is there any other quick fix to this:
Main Time line:
if (ready ==1)
do something;
movieClip1 Time line:
_root.ready = 1;
from the main time line I am loading an external swf into
movieClip1, and am trying to catch when a certain condition is met
by changing a variable. Problem is I can't reference the variable
in the movieClip1 from the main time line. Any suggestions?

1) Do not you _root because it return to the main time line
of the loaded Movie.
2) you must load the movie then go to excute code in
timeline.
3) from inside the loaded Movie use code like this:
MovieClip(parent.parent)["ready"] = 1
