Using the Flash CS4 i had a little problem… everytime i tried to use the text tool, either flash crashed after or before even putting the text box on stage.

Thinking it was a flash bug i google search it… i found this.

i read only a few top posts and found that the issue was the computer performance, but then David here at W has the same computer as me. After formatting my pc flash was running ok, so there, problem fixed!

BUT when i put all of my stuff back in, again flash was doing the same thing. After a few hairs pulled and desks banged, we discover that it was the fonts i installed in the pc the day before, and going back to the link i found , reading all of the posts, Raúl found that same solution posted there.

What did we learn from this?
1: you don’t need to install every font you find.
2: read a little more before taking actions with the first post you find XD so you don’t have to format your computer in vain. XD

well this is a handy code snippet to validate a string
if you want to avoid some bad words, this is for you:

function isValid(str:String):Boolean {
        var regExp:RegExp = /\b(badword|nastyWord)\b/i;
	var _isValid:Boolean = !regExp.test(str);
        return _isValid;
}
 
var _inValidMessage = "this is a example for a bad badword it's really nasty";
var _validMessage = "Hello Word!";
 
trace(isValid(_inValidMessage)) //false
trace(isValid(_validMessage))//true

you can add more words just separating them by a pipeline ( | ) in the Regular Expression

Cheers.

As promised on youtube: here it’s the source

( thx to saqoosha for the help on the flarToolkit issue of translating the flag fixed vertex… you can find his example of doing this on his site, but he maded it for away3d =) )

the code is very extended, so if you have any doubts post them here, we will try and answer all of them

Well this is i think the most common pattern that i use in my apps
it’s not the exact implementation but it works for me =D

here’s and example on how i use it
Read the rest of this entry »

i was looking something like the “Activity” Window in Safari for Firefox and found this handy extension HttpFox

it comes very useful when you want to track your content-page information

cheers!.

hi guys! well we’ve been busy these days, in fact some of us didn’t have vacations these holidays
so you can imagine the load of work that we have
we promise to post some interesting things just in a couples of days (or weeks =D hehe)

meanwhile you can visit our new blog http://blog.grupow.com

cheers!

Hi everyone!, well we want to share you all the JSFL Commands that we found on the web,
these extensions have been very useful here at GrupoW our productivity increased like a 98%
and the graphic designer team have blessed us =D so here they are!!

i think you don´t need an explanation in how to install it and how to use it, they are very self descriptive

DownThemAll!

use them wisely

if you know about other useful extensions don’t hesitate on posting them

GrupoW Developer Team

Here we have a quick example on how to change the texture of a primitive object in papervision3d…

At the end this is what you get:

This is the Document Class, its pretty simple and the methods are self descriptive so i don’t think you’ll have any trouble using it :

you can download the source code too! =)

in AS2 sending and receiving variables was easy, you could do it even with your eyes closed =D
but in AS3 is another story

remember AS2??

1

var lv:LoadVars = new LoadVars();
lv.username = "ruliman";
lv.password = "123456";
lv.sendAndLoad("somefile.php",lv,"POST");

nice isn’t??

in AS3

var variables:URLVariables = new URLVariables();
variables.username = "ruliman";
variables.password= "123456";
//
trace(variables.toString());
var request:URLRequest = new URLRequest("somefile.php");
request.method = URLRequestMethod.POST;
request.data = variables;
 
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
 
try{
	loader.load(request);
}
catch (error:Error) {
	trace("Unable to load URL");
}

until here you can say “well it isn’t too bad just a bunch of classes, but is better organized =) i love AS3 ”

but……..when you compile Flash tell you this!

Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
at Error$/throwError()
at flash.net::URLVariables/decode()
at flash.net::URLVariables$iinit()
at flash.net::URLLoader/flash.net:URLLoader::onComplete()

MUAHAHAAA!!!

the PHP code is simple

1
2
3
4

<?
$user= $_POST["username "];
$pass= $_POST["password"];
?>

so…………where the error is coming from??
i google it and found this answer, is very simple:
my php wasn’t returning something so, put an echo throwing some variable something like:

1
2
3
4
5
6

<?
$user= $_POST["username "];
$pass= $_POST["password"];
 
echo "result=success";
?>

and that’s it everything compiles normal, now i can go back to dinner =D

i was trying to read an XML with namespaces and then Flash throw me this weird error

VerifyError: Error #1025: An invalid register 3 was accessed


then we found that was beacuse of these lines (locally declared in a function)

1
2

var ns = ttXML.namespace();
default xml namespace = ns;

the error comes when you try to call some function after those lines in your code

the solution that we found was declare ns variable outside of the function
and then everything works fine =D
