vrworld/isvalid

Return 1 if the vrworld object is valid, and 0 if it is not

Syntax

• x = isvalid(vrworld_object)
  

Arguments

vrworld_object

Name of 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 where the elements of vrworld_object are valid vrworld objects, and returns a 0 where 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.
