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

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

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:
The Flash plugin is required to view this object.
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 :

in AS2 sending and receiving variables was easy, you could do it even with your eyes closed =D
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.
MUAHAHAAA!!!
the PHP code is simple
1

<?
$user = $_POST [ "username " ] ;
$pass = $_POST [ "password" ] ;
?>
so…………where the error is coming from??
1

<?
$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
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

well we start with this Sound Util, just embed the SoundTransform and SoundChannel in one single Class and the fade ability (uses Tween Lite )
