No need to get hyper about "this". The matter stays that "this" used to be essential in AS1, thus probably why people still like to implicate him in their code. But I agree that putting "this" in an AS2 Class should be used only when necessary.

Only reason keyword "this" exists is if you want to pass reference to current object somewhere, in which case you must use "this". To me using "this" in your code makes you look like wannabe-programmer, :) But I gues its matter of taste. btw, old VB does not have "this" keyword, and if you were reffering to VB(.NET), it is more OOP and more complex than AS3, so I gues programmers in VB.NET (if there are some, since C# is there) are not wannabe-programmers :) "ryanm" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] >> What I don't get is why it needs "this.addChild" instead of just >> addChild.
