I have made two netowrking scripts so far. here is the first.

using UnityEngine;
using System.Collections;
using System;

public class MPBase : MonoBehaviour 
{

    public string connectToIp = "127.0.0.1";
    public int connectPort = 25000;
    public bool useNAT = false;
    public string ipaddress = "";
    public string port = "";

    string playerName = "<NAME ME>";

    void OnGUI()
    {
        if (Network.peerType == NetworkPeerType.Disconnected)
        {
            if (GUILayout.Button("Connect"))
            {
                if (playerName != "<NAME ME>")
                {
                    Network.useNat = useNAT;
                    Network.Connect(connectToIp, connectPort);
                    PlayerPrefs.SetString("playerName", playerName);
                }
            }

        if (GUILayout.Button("Start Server"))
        {
            if (playerName != "<NAME ME>")
            {
                Network.useNat = useNAT;
                Network.InitializeServer(32, connectPort);

                foreach (GameObject go in FindObjectsOfType(typeof(GameObject)))
                {
                    go.SendMessage("OnNetworkLoadedLevel", SendMessageOptions.DontRequireReceiver);
                }
                PlayerPrefs.SetString("playerName", playerName);
            }
        }
            playerName = GUILayout.TextField(playerName);
            connectToIp = GUILayout.TextField(connectToIp);
            connectPort = Convert.ToInt32(GUILayout.TextField(connectPort.ToString()));
        }
        else
        {
            if (Network.peerType == NetworkPeerType.Connecting) GUILayout.Label("Connect Status : Connecting");
            else if (Network.peerType == NetworkPeerType.Client)
            {
                GUILayout.Label("Connection Status : Client!");
                GUILayout.Label("Ping to Server: " + Network.GetAveragePing(Network.connections[0]));
            }

            else if (Network.peerType == NetworkPeerType.Server)
            {
                GUILayout.Label("Connection Status : Server!");
                GUILayout.Label("Connections: " + Network.connections.Length);
                if (Network.connections.Length >= 1)
                    GUILayout.Label("Ping to Server: " + Network.GetAveragePing(Network.connections[0]));
            }

            if (GUILayout.Button("Disconnect"))
                Network.Disconnect(200);

            ipaddress = Network.player.ipAddress;
            port = Network.player.port.ToString();
            GUILayout.Label("IP Address: " + ipaddress + ":" + port);
        }
    }

    void OnConnectedToServer()
    {
        foreach (GameObject go in FindObjectsOfType(typeof(GameObject)))
        {
            go.SendMessage("OnNetworkLoadedLevel", SendMessageOptions.DontRequireReceiver);
        }
    }
}

This was written in C#. Now here is the next, also written in C#

using UnityEngine;
using System.Collections;

public class SpawnScript : MonoBehaviour 
{
    public Transform player;

    void OnServerInitialized()
    {
        SpawnPlayer();
    }

    void OnConnectedToServer()
    {
        SpawnPlayer();
    }

    void SpawnPlayer()
    {
        Network.Instantiate(player, transform.position, transform.rotation, 0);
    }

    void OnPlayerDisconnected(NetworkPlayer player)
    {
        Network.RemoveRPCs(player);
        Network.DestroyPlayerObjects(player);
    }

    void OnDisconnectedFromServer(NetworkDisconnection info)
    {
        Network.RemoveRPCs(Network.player);
        Network.DestroyPlayerObjects(Network.player);
        Application.LoadLevel(Application.loadedLevel);
    }
}

And I also added this code to my MouseLook script and FPS Script (JavaScript)

function Start()
{
    if(!networkView.isMine)
    {
        enabled = false;
    }
}

function Whatever() {
if(networkView.isMine){
//do whatever 
}
}

The only problem is that when I connect with two clients, Player1 controls player 2's character and Player2 controls Player1's. Please leave a response or help me one on one by contacting me at fiercemodz@gmail.com
