NetworkServer.SendToClient

Parameters

Description

Send a message to the client which owns the given connection ID.

It accepts the connection ID as a parameter as well as a message and MsgType. Remember to set the client up for receiving the messages by using NetworkClient.RegisterHandler. Also, for user messages you must use a MsgType with a higher ID number than MsgType.Highest.

//The code shows how to set up a message, the MsgType and how to get the connectionID.
//It also shows how to send the message to the client, as well as receive it.
//Attach this script to a GameObject

//Create a class for the message you send to the Client
public class RegisterHostMessage : MessageBase

    public string m_Name;
    public string m_Comment;
}

    //This is the Message Type you want to send to the Client. User messages must be above the Highest Message Type.

        //Send the new message to the Client using the Server
        NetworkServer.SendToClient(connection.connectionId, m_MessageType, m_Message);
    }

    //On the Client's side, detect when it connects to a Server
    public override void OnClientConnect(NetworkConnection connection)
    {
        //Register and receive the message on the Client's side
