[Flashcoders] Question on variable init in a for loop
I have the following case:
var l:Array = [{},{}]
function test():void{
for each(var i:Object in l){
var id:String;// = null;
trace(1 ,id);
id = test + Math.random().toString();
trace(2 ,id);
}
}
I seems that 'id' is not resetted to null on every iteration as I would
expect. I have to explicitly set the id to null myself! Does some know
why this is, or are my expectations just wrong.

[Flashcoders] [SOLVED] flvplayback fullscreen button
i've just found out what the problem was i've reverted to my previous version of the cut down players (that use the flvplayback component) and set fullscreentakeover to false (as it is in the main player) and it fixed the problem - apparently when the fullscreen state is called, all of the flvplayback instances will try to react to it in their own way and if they are set to take over the screen, they will fight the player we actually want to use if it doesn't. ouch - 2 hours i'll never get back a On 4 August 2010 10:48, allandt bik-elliott (thefieldcomic.com) alla...@gmail.com wrote: hi i've replaced the other instances of the flvplayback (that don't require controls) with standard netstream / netconnection / video players and it solved the problem.

Re: [Flashcoders] Question on variable init in a for loop
no that's correct but id should be declared outside of your loop - as3 will
actually give you a duplicate variable error for putting it inside the loop.
you can also refer to your iterator (i) after the loop is done
i'd rewrite your function like this
var arObj:Array = [{},{}]
function test():void
{
var id:String;
for each(var i:Object in arObj)
{
trace(1 ,id);
id = test + Number(Math.random()).toString();
trace(2 ,id);
}
trace(i);
}

Re: [Flashcoders] Question on variable init in a for loop
In actionscript you have only local and global scope. Meaning a variable
can be declared as local to the function or in the class that contains it.
Other languages allow for creating further scopes. In Java, C, C++, C#, for
instance, you can do something like this:
int i = 0;
{// this creates a new scope
int i = 8;
}
And you will get 2 different variables. Obviously, naming both the same is
not the smartest move, but it's legal (at least in C#, if I recall
correctly).
Also when you write a loop, the counter var will be local if declared in the
loop. I mean this:
for(int i = 0; i 10; i++) {
// do something with i
}
//this is invalid, i doesn not exist here...
i = 20;
Now, in Actionscript this is not possible. You can declare a variable
wherever you like. The compiler ends up moving the variable to the top of
the scope when generating the bytecode (I think this is called hoisting).
So this:
var l:Array = [{},{}]
function test():void{
for each(var i:Object in l){
var id:String;// = null;
trace(1 ,id);
id = test + Math.random().toString();
trace(2 ,id);
}
}
Is equivalent to writting this:
var l:Array = [{},{}]
function test():void{
var id:String;// = null;
for each(var i:Object in l){
trace(1 ,id);
id = test + Math.random().toString();
trace(2 ,id);
}
}
id will be declared (and initialized to null) only once, before you access
it in your code. So you only have one variable, really and that's the reason
for the behavior you observed.

RE: [Flashcoders] Question on variable init in a for loop
Hope to add some value to this.
The duplicate variable error is only due to the fact that String is a native
object (don't know the correct name for this) of Flash AS3.
So you don't have to use the new key word for it.
Like this would work OK:
var arObj:Array = [{},{}]
function test():void
{
for each(var i:Object in arObj)
{
var id:MovieClip = new MovieClip()
trace(1 ,id);
id.name = test + Number(Math.random()).toString();
trace(2 ,id);
}
trace(i);
}

Does anyone know where I might find an AS2 (preferably) or AS3 create your own t-shirt tutorial or any advice on one that is made and for sale? Does your t-shirt maker also have to have sharks and lasers? I had no luck on google, but I may not be searching for the right key phrase. Try this search: Flash Tutorial T-Shirt Maker Sharks Lasers Seriously though, you're thinking about this the wrong way - looking for an EXTREMELY specific example. You need to not think about the specific result you want (because it's extremely unlikely you'll find a tutorial on it), and instead ask questions and find tutorials on knowledge gaps in Actionscript and Flash related to the problem you are trying to solve. For example: How do I detect when two graphics are overlapping? How would I go about allowing the user to draw on the screen? How can I send graphics to a printer? Is there a tutorial out there on loading XML? etc. By asking for a tutorial very specific to your project, it seems like you just want something to show you everything you should do for your project, instead of learning the Flash/Actionscript things you need to learn to tackle any project. So I would advise you to learn to fish instead of ask for a fish. Sorry if that sounds harsh, I don't mean it to be - it's just the best advice I can give you.

Re: [Flashcoders] Question on variable init in a for loop
Public variables, static or otherwise do NOT classify as global variables. http://en.wikipedia.org/wiki/Global_variable A global variable is something that is accessible everywhere without any scope whatsoever. By having to call MyClass.variable or myClassInstance.variable, it is quite apparent that the property variable is not global, because you have to explicitly call MyClass or a MyClass instance to access it. Now, some developers might imitate global variables in AS3 by doing something like making a class called Global, and accessing static variables such as Global.variable1, Global.variable2, etc. Taka On Wed, Aug 4, 2010 at 11:15 AM, Kerry Thompson al...@cyberiantiger.bizwrote: Henrik Andersson wrote: Public static properties are the only thing that can be compared with a global.

Try this search: Flash Tutorial T-Shirt Maker Sharks Lasers Seriously though, you're thinking about this the wrong way - looking for an EXTREMELY specific example. You need to not think about the specific result you want (because it's extremely unlikely you'll find a tutorial on it), and instead ask questions and find tutorials on knowledge gaps in Actionscript and Flash related to the problem you are trying to solve. For example: How do I detect when two graphics are overlapping? How would I go about allowing the user to draw on the screen? How can I send graphics to a printer? Is there a tutorial out there on loading XML? etc. By asking for a tutorial very specific to your project, it seems like you just want something to show you everything you should do for your project, instead of learning the Flash/Actionscript things you need to learn to tackle any project. So I would advise you to learn to fish instead of ask for a fish. Sorry if that sounds harsh, I don't mean it to be - it's just the best advice I can give you.

Re: [Flashcoders] Question on variable init in a for loop
That's an over simplification of the scope chain properties of AS3,
and global isn't the right word there (though I know what you meant).
To clarify the scope chain issue, keep in mind that you can nest
function scopes to create a hierarchy of scopes with a closure (usually
this is difficult for new devs in ECMAScript languages like AS3 and
Javascript to grasp). So global really just refers to the top of the
scope chain.
Additionally, there are also as file level scopes. For example, in a
file named getURL.as:
package {
function getURL() {
trace(topScopeVar);
}
}
var topScopeVar:String = Hello world!;
That topScopeVar is only accessible from within that as file, because
it is at the top of that file's individual scope chain. A function or
class in a different as file would not have access to that variable, and
this class has no access to other seemingly global scopes either, like
the timeline, or other as files.
functions and classes defined in root packages, and available in the
class path, those are global, and you can define a property on those
(static var on a class for example) - that's about as close as you get
to a global in AS3.

Re: [Flashcoders] Question on variable init in a for loop
It's not a global because if you have a MovieClip called testMC on the stage and are inside testMC and try to do trace(greeting), you will get an error. To access that property you have to do parent.greeting, therefore because you have to be aware of the scope to access it, it is not global.

[Flashcoders] Latest advances in Automated Flash/Flex Testing - learn more tomorrow (Aug 5, 11a PDT)
Hi there, Thought you'd like to know that Sauce Labs has bundled Flash/Flex Testinghttp://saucelabs.com/flashsupport with Sauce IDE (Sauce's value distribution of Selenium). If you are interested in automating the testing your Flash/Flex components along with the rest of your browsers, and find the existing tools (FlexMonkey / Flash Selenium / Selenium Flex API) limiting: There is a webinar http://saucelabs.com/about/webinars#webinar-flex on *August 5, 2010 at 11 am PST* to show you everything you need to know. Checkhttp://www.timeanddate.com/worldclock/fixedtime.html?month=8day=5year=2010hour=11min=0sec=0p1=224your time zone here. Adam Christian (co-creator of Flex Pilot and Windmill) will walk you through the steps of creating tests for your Flash/Flex components; running these tests in Java, Python, Ruby, php; and executing your tests in the cloud on Sauce OnDemand http://saucelabs.com/ondemand against different browsers and OSs. Register for the webinar now at: http://saucelabs.com/about/webinars#webinar-flex Until now, most QA rely on manual testing for Flash and Flex. With the speed this system is capable of, continuous integration with Hudson is snap, and your need for developers to rewrite hooks for automated testing will be drastically reduced. Feel free to spread the word and hope to see you at the webinar! -- Grace Law Follow us on twitter.com/saucelabs ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Question on variable init in a for loop
Agreed, that was over simplified.
I probably should have said clearly I was using global in a rather loose
way -- as opposed to function local; that's why I put the quotes. I just
wanted to point out what the problem was in the original question, in a
simple way, without getting into activation objects and other stuff.
Thanks for your clarifications.

Re: [Flashcoders] Create your own t-shirt
And you need to find out how to send a ByteArray back to a backend service to save said t-shirt as an image file. With that and Jack's TransformManager, those are the two main building blocks. Having created quite a few online designers / product customisation tools, I'd add that for print resolution imagery involving bitmaps you certainly -don't- want to be transferring large amounts of pixel data back to the server, compression or not (unless you don't mind long waits or low resolution output affecting your customer abandonment rates). Better to keep all high resolution processing (and files) on the server and to essentially only transfer user interaction data back to the server to render out the print ready, high resolution final format there, while keeping the whole process snappy. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Create your own t-shirt
Actually I've seen one that let's you turn pixels transparent when uploading your image. Like white pixels. But were not printing the tshirt from what you create, that is just the example for us to go by. So it doesn't need that effect IMO.
