Hi,

I'm struggling to grasp the concept of setting up a proper server/client network for a turn based board game. What I basically want is restrict certain actions for a player until it is his turn. I created a Lobby where players can create a server/game and other players can retrieve a list of servers and join them. When the server is full of players it will load a new Scene for the game. But i cannot get this turn based structure to work.

Here is some code for the lobby:

When a player starts the game the player can press the "create game" button that loads this function:

private void StartServer()
{
  Network.InitializeServer(2, 25000, false);
  MasterServer.RegisterHost(gameName, "Test game 2", "Welcome to for a row!");
  GameObject canvas = GameObject.Find("Canvas");
  canvas.SetActive(false);
}

private void GameButton(HostData hostData)
{
	Debug.Log(hostData.gameName);
	Network.Connect(hostData);
	Application.LoadLevel("GameScene");
}

private void OnPlayerConnected(NetworkPlayer player)
{
	Debug.Log(player.externalIP + " Has connected!");		
	Application.LoadLevel("GameScene");
}

Network.Instantiate(prefab, Vector3.zero, Quaternion.identity, 0);

Thanks Ashaman,

But the problem is the player that creates the server is actually the server and not a client. Or am I missing something here? I have looked into creating a server on the MaterServer and then joining the player that created it to it but without success. I know I am not understanding the concept completely, trying to get there.

//I am actually getting somehwere. Using RCP i found out that the server player is NetworkPlayer.toString() == -1 and the other connected player is NetworkPlayer.toString() == 1.

I think i got it. What the problem is with the Network system of unity is that a player that creates the server has to act differently. This is not documented anywhere. I just created a test that finally seems to do what I want.

if (Input.GetMouseButtonDown(0))
{
	if (Network.isServer)
	{
		SentMouseClick(Input.mousePosition); //Do not sent a RPC call otherwise the NetworkPlayer will be -1 and not identical to the "server player" on the network.
	}
	else
	{
		networkView.RPC("SentMouseClick", RPCMode.Server, Input.mousePosition);
	}
}

        //Create a function for the clients [RPC] and for the player on the server. This still seems awkward to me
	[RPC]
	private void SentMouseClick(Vector3 v, NetworkMessageInfo info)
	{
		Debug.Log("Player (" + info.sender.ToString() + ") clicked at: " + v);
	}
	private void SentMouseClick(Vector3 v)
	{
		Debug.Log("Player (" + Network.player.ToString() + ") clicked at: " + v);
	}

Now i am wondering with what you mean with a token? But at least i can verify a move from a player on the server and instantiate or alter the scene on the server.

So with the knowledge gained above I started fiddling around and am wondering if this is a proper way of doing it. The server player and the client can in turn press a button that get registered by the server. It possibly also works with many clients but not tested that yet. Everything coded within the if (myTurn) statement is only executed when it really is the clients turn. Everything outside still works.

Still wondering if this is a good approach. Would love to have some feedback.

	//server fields
	private NetworkPlayer player;
	private NetworkPlayer[] playerPool;
	private int currentPlayer;

	//player fields
	private bool myTurn = false;


	// Use this for initialization
	void Start () {
		player = Network.player;

		if (Network.isServer)
		{
			playerPool = new NetworkPlayer[Network.connections.GetLength(0) + 1];
			playerPool[0] = player; //Adds server player to the pool
			//Put all clients in the pool
			for (int i = 0; i < Network.connections.GetLength(0); i++)
			{
				playerPool[i + 1] = Network.connections[i];
			}
			//give someone the first turn
			currentPlayer = Random.Range(0, playerPool.GetLength(0) - 1);
			networkView.RPC("GiveTurn", RPCMode.All, playerPool[currentPlayer]);

			//list players in pool
			foreach (NetworkPlayer p in playerPool)
			{
				Debug.Log("Player (" + p.ToString() + ") added to pool");
			}
		}
	}

	void Update () 
	{
		if (myTurn)
		{
			if (Input.GetMouseButtonDown(0))
			{
				if (Network.isServer)
				{
					EndTurn();
					myTurn = false;
				}
				else
				{
					networkView.RPC("EndTurn", RPCMode.Server);
					myTurn = false;
				}
			}
		}
	}

	[RPC]
	private void GiveTurn(NetworkPlayer player)
	{
		if (Network.player.ToString() == player.ToString())
			myTurn = true;
		Debug.Log("Player (" + player.ToString() + ") is ready to act.");
	}

	[RPC]
	private void EndTurn(NetworkMessageInfo info)
	{
		Debug.Log("Player (" + info.sender.ToString() + ") ended his turn.");
		currentPlayer++;
		if (currentPlayer >= playerPool.GetLength(0))
			currentPlayer = 0;
		Debug.Log(currentPlayer + ", " + playerPool.GetLength(0));
		networkView.RPC("GiveTurn", RPCMode.All, playerPool[currentPlayer]);
		
	}
	private void EndTurn()
	{
		Debug.Log("Player (" + Network.player.ToString() + ") ended his turn.");
		currentPlayer++;
		if (currentPlayer >= playerPool.GetLength(0))
			currentPlayer = 0;
		networkView.RPC("GiveTurn", RPCMode.All, playerPool[currentPlayer]);
	}
