class in UnityEngine.Networking
A Custom Attribute that can be added to member functions of NetworkBehaviour scripts, to make them only run on servers.
A [Server] method returns immediately if NetworkServer.active is not true, and generates a warning on the console. This attribute can be put on member functions that are meant to be only called on server. This would be redundant for [Command] functions, as being server-only is already enforced for them.
