Unity Multiplayer [Command] between 2 different scripts

I am trying to learn how to use remote actions: http://docs.unity3d.com/Manual/UNetActions.html
Problem is all the examples have sending part in the same class as the receiving part.

In my case I have a ClientController and a ServerController. The servercontroller script is only runned by the server and the clientcontroller by the clients.

Now let's say I want to send a login request sending a username:

Client (ClientController.cs):

Code (CSharp):

1. userName = GUI.TextField(new Rect(10, 10, 200, 20), userName, 25);
2.             if(GUI.Button(new Rect(10, 40, 120, 30), "Login")) {
3.                 CmdLogin(userName);
4.             }

Server (ServerController.cs):

Code (CSharp):

1.     [Command]
2.     void CmdLogin(string userName) {
3.         Debug.Log(userName);
4.     }

Because the command is in a different class it gives the following error: error CS0103: The name `CmdLogin' does not exist in the current context

Problem is I also can't reference to the function because the ServerController script doesnt run on clients...

How do I fix this?

 

Commands have to be on the same behaviour of the same object, so you have to put your methods on your player. In your simple case you can just move the method from ServerController to ClientController, since the clientcontroller is probably your player object and thus on the server, too.

 

Then how can I make main controllers for both the client and server handeling more general stuff?
I am looking for a function like the RPC's from the old networking engine. Every object could send them...

What about if you have a Server in a complete different Unity project? Can't understand the logic...

 

Send a message if you want to. Commands make object syncronization very simple and work only on its own object.
If you want to send something to a central server object, just register a messagehandler.

http://docs.unity3d.com/Manual/UNetMessages.html

 

Only the player object?
I think it's kinda weird if the player object sends a login request from the menu?

 

That's why you can use messages across everything.

On the server:

Code (csharp):

1.  
2. void Start(){
3. NetworkServer.RegisterHandler(1000, OnLoginRequest); // 1000 -> your own short message type
4. }
5. void OnLoginRequest(NetworkMessage msg){
6. Debug.Log(msg.ReadMessage<StringMessage>().value);
7. }
8.  

Client:

Code (csharp):

1.  
2. void Whenever(){
3. NetworkClient.Send(1000, new StringMessage("Peter"));
4. }
5.  

 

And what if I want to add more arguments? Like RPC's?

 

You can write your own message types. Or you can send it to your playerobject and after that to your server:

Code (csharp):

1.  
2. public class MyPlayer : NetworkBehaviour{
3. [Command]
4. void CmdLoginMessage(string name, string passwordHash){
5.     MyServerObject.Login(name, passwordHash);
6.   }
7.  
8. void YourLoginMethod(){
9.     CmdLoginMessage("Peter", "23425ff");
10.   }
11. }
12.  

Since commands are only possible on your own playerobjects, you can always use "connectionToClient" to determine which client sent the data, e.g. MyServerObject.Login(connectionToClient, name, passwordHash);

 

Thanks for the help guys, I figured out how to send messages
