CommandAttribute

Описание

This is an attribute that can be put on methods of NetworkBehaviour classes to allow them to be invoked on the server by sending a command from a client.

[Command] functions are invoked on the player object associated with a connection. This is setup in response to the "ready" message, by passing the player objec to the NetworkServer.PlayerIsReady() function. The arguments to the command call are seriialized across the network, so that the server function is invoked with the same values as the function on the client. These functions must begin with the prefix "Cmd".
