New guy to networking, is there other networking API available

Hey guys,

I used to do some networking on garry's mod, and i really don't understand all this RPC and Command stuff on Unity, is there something like

Code (csharp):

1.  
2. net.StartMessage("UniqueMessage");
3. net.WriteInt8(some_integer);
4. net.WriteGameObject(this);
5. net.SendToServer();
6.  

and something on the server side :

Code (csharp):

1.  
2. net.HookNetMessage("UniqueMessage", void func);
3.  

 

Let me try to explain Command And RPC.
A method marked with Command:
Everything inside this method is Server code and only gets executed on the server. A command can be requested to be run by client.
So if you are a client and call a command method. You basically send a packet to the server saying "Run YOUR equivilant of this method".
If the server then wants to send something to the other clients. Thats a RPC.
Let me show an example

Code (CSharp):

1. void Start()
2. {
3.     if(isLocalPlayer)
4.     Cmd_ServerCode();
5. }
6.  
7.  
8. void Cmd_ServerCode()
9. {
10.     Rpc_ClientCode();
11. }
12.  
13. void Rpc_ClientCode()
14. {
15.     Debug.Log("Ran on every client");
16. }

So if you for example want to pick up an item. You send a Command to pick it up. And in that command you can then verify. Is he looking at it? Raycast etc so the player cant modify. Please note commands can only be called if you are the local player and have authority of the object you are calling it.


Hope I clearified a bit more.
