vrworld/isvalid

(To be removed) 1 if vrworld object is valid, 0 if not

vrworld/isvalid will be removed in a future release. For more information, see Version History.

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.

R2023b: To be removed

The vrworld/isvalid will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks to interface MATLAB^® and Simulink^® with the Unreal Engine^® 3D simulation environment. To get started, see Create 3D Simulations in Unreal Engine Environment.
