vrworld/isvalid - 1 if vrworld object is valid, 0 if not
Syntax
x = isvalid(vrworld_object)
Arguments
vrworld_object | A vrworld object representing a virtual
world. |
Description
A vrworld object is considered valid if its
associated virtual world still exists.
x = isvalid(vrworld_object) returns an array
that contains a 1 when the elements of vrworld_object are
valid vrworld objects, and returns a 0 when
they are not.
You use this method to check whether the vrworld object
is still valid. Using a delete or vrclear command
can make a vrworld object invalid.
