Playing with Pixels

By raúl | July 22, 2009

i was just playing with pixels and BitmapData
the code is a little messy and is not optimized

at the end we didn’t use it on production but is a really nice mouse trial
hope you like it!

function alwaysOnTop_handler(e:Event):void {
	//make this child always on top!
	parent.addChild(this);
}
 
function added_handler(e:Event):void {
	parent.addEventListener(Event.ADDED, alwaysOnTop_handler, false, 0, true);
}
 
addEventListener(Event.ADDED_TO_STAGE, added_handler, false, 0, true)

Grupo W @ badFonts group [ Flash CS4 text properties issue ]

By wolf | April 8, 2009

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

Validating a String

By raúl | April 6, 2009

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

1
2
3
4
5
6
7
8
9
10
11
12

 
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 =) )
