When you do lots of any language you build up libraries over time that are time savers that are repetitive and tedious if you do not consoildate into a library.  Taking a look at the CASALib, an as3 library of common functions for flash that was released I have many of the same things in my libraries but CASALib just has lots of extras that go a bit deeper than some libraries, is very clean and is organized pretty well.

One cool thing about it is the IDestroyable interface and the CasaMovieClip, CasaSprite, CasaTextField , etcthat all have a destroy() method that cleans up all events, removed instances and even removes it from the parent display object. Gets me thinking why this isn’t just part of DisplayObject in the first place.

From the release:

Here are a few of our favorite things in CASA Lib AS3:

  • Standardized external load API
  • Easily remove listeners with IRemovableEventDispatcher
  • destroy methods make garbage collection easy
  • Large group of utility classes for common manipulations

We will be elaborating further the power of CASA Lib in future blog posts.

As with any new release there will be bugs that emerge, but with your help we promise to release updates often to keep CASA Lib as stable as possible.

I have been doing lots of Papervision 3D for a project recently and needed to debug some placement and camera issues.  I did a quick search and found PV3DDebug by Jason Bejot and it worked out great and is a pretty sweet utility I thought I would mention when you need to debug Papervision or even for inclusion as a debug console in all your papervision apps and games. It is a good base for your own consoles or debug panels. It is also a great tool to help out with focus and zoom issues and understanding with camera placement.

The code is really easy to drop in and you can get lots of info on the PV3D scenes and camera manipulation.

I had to implement a get age method for something we were working on. I was surprised to not find an AS3 version easily, so busted one out. I thought maybe this would be in as3corelib but nope. So posting this in case anyone else is looking for a get age script in AS3. It was quick so any improvements just post them. It will be added to my utilities classes on google code soon it is in quick form so you can jsut plop in an .fla or a class.

The pseudo code is the same for getting age in any language. Get current date, get birthdate to compare. Subtract the current years from the birthday years, then subtract one more year if the day or month is less than today’s day and month.

function calculateAge(birthdate:Date):Number {
    var dtNow:Date = new Date();// gets current date
    var currentMonth:Number = dtNow.getMonth();
    var currentDay:Number = dtNow.getDay();
    var currentYear:Number = dtNow.getFullYear();

    var bdMonth:Number = birthdate.getMonth();
    var bdDay:Number = birthdate.getDay();
    var bdYear:Number = birthdate.getFullYear();

    // get the difference in years
    var years:Number = dtNow.getFullYear() - birthdate.getFullYear();
    // subtract another year if we're before the
    // birth day in the current year
    if (currentMonth < bdMonth || (currentMonth == bdMonth && currentDay < bdDay)) {
    return years;

function dateStringToObject(dateString):Date {
    var date_ar = dateString.split("/");
    return new Date(date_ar[2],date_ar[0] - 1,date_ar[1]);

var dateNow:Date = new Date();
var checkDate:String = "11/25/1976";
var dateBirthday:Date = dateStringToObject(checkDate);
trace("dateNow = "+dateNow);
trace("dateBirthday = "+dateBirthday);
trace("age = "+calculateAge(dateBirthday));
