Re: testing if a clip exists (was, Re: FLASH: null is >, <, =, or ? to zero)

[V�ctor Vill�n]

Hi.


About your question: If a movie clip doesn't exist and you try to evaluate

some of his properties u will be returned nothing, so, if you want to test

if it exists then try: If (Getproperty("movie",_x) eq "") "It doesn't exist"

End If. But, as JD said, it has no sense.


About the JD reply, I think he tried to say something like that:


  There's no reason to test if a movie clip exists if u have made the code a

way u know certainly it will/will not exist.


Bye
