Obsolete public bool dontDestroyOnLoad ;

説明

A flag to control whether the NetworkManager object is destroyed when the Scene changes.

This should be set if your game has a single NetworkManager that exists for the lifetime of the process. If there is a NetworkManager in each Scene, then this should not be set.
