Hello there, am creating network game. I followed one of the tutorial and create a script for network connection, now am having this error.

Error : “Cannot implicitly convert type UnityEngine.HostData[]' to bool’”

here is the code:

using UnityEngine;
using System.Collections;

public class NetworkManager : MonoBehaviour 
{
	public GameObject Car;
	public Transform Spawn_Point;
	public string Game_Name = "Car_Game";

	private bool Refreshing;
	bool Network_Service;
	private float Button_x;
	private float Button_y;
	private float Button_w;
	private float Button_h;
	private HostData[] Server_Data;

	void Start()
	{
		Button_x = Screen.width * 0.05f;
		Button_y = Screen.width * 0.05f;
		Button_w = Screen.width * 0.1f;
		Button_h = Screen.width * 0.1f;
	}

	void StartServer()
	{
		Network_Service = !Network.HavePublicAddress();
		Network.InitializeServer(32, 25001, Network_Service);
		MasterServer.RegisterHost(Game_Name, "Car_Game", "This is a test");
	}

	void RefreshHostList()
	{
		MasterServer.RequestHostList (Game_Name);
		Refreshing = true;
	}

	void Update()
	{
		if(Refreshing)
		{
			if(MasterServer.PollHostList().Length > 0)
			{
				Refreshing = false;
				Server_Data = MasterServer.PollHostList ();
			}
		}
	}

	void CarSpawn()
	{
		Network.Instantiate (Car, Spawn_Point.position, Quaternion.identity, 0);
	}

	void OnServerInitiatlized()
	{
		Debug.Log ("Server Initialisation");
		CarSpawn ();
	}

	void OnConnectedToServer()
	{
		CarSpawn ();
	}

	void OnMasterServerEvent(MasterServerEvent MSE)
	{
		if(MSE == MasterServerEvent.RegistrationSucceeded)
		{
			Debug.Log ("Registered Server");
		}
	}

	void OnGUI()
	{
		if(!Network.isClient && !Network.isServer)
		{
			if(GUI.Button(new Rect(Button_x, Button_y, Button_w, Button_h),"Start Server"))
			{
				Debug.Log ("Starting Server");
				StartServer();
			}
			if(GUI.Button(new Rect(Button_x, Button_y * 3 + Button_h, Button_w, Button_h),"Refresh Host"))
			{
				Debug.Log ("Refreshing");
				RefreshHostList();
			}
			if(Server_Data)
			{
				for(int i = 0; i < Server_Data.Length; i++)
				{
					if(GUI.Button(new Rect(Button_x * 1.5f + Button_w, Button_y * 1.2f + (Button_h * i), Button_w * 3, Button_h * 0.5f),Server_Data*.gameName))*

Network.Connect(Server_Data*);

As you are storing the HostData in Server_Data I assume you want to know if there is any server available to show the buttons for them.

If this is the case, you don’t need the if in line 89 as the execution won’t enter the for loop if there is no HostData (i.e.: Server_Data.Lenth is 0).

Just remove if (Server_Data) like this:

    void OnGUI()
    {
        if(!Network.isClient && !Network.isServer)
        {
            if(GUI.Button(new Rect(Button_x, Button_y, Button_w, Button_h),"Start Server"))
            {
                Debug.Log ("Starting Server");
                StartServer();
            }
            if(GUI.Button(new Rect(Button_x, Button_y * 3 + Button_h, Button_w, Button_h),"Refresh Host"))
            {
                Debug.Log ("Refreshing");
                RefreshHostList();
            }
            for(int i = 0; i < Server_Data.Length; i++)
            {
                if(GUI.Button(new Rect(Button_x * 1.5f + Button_w, Button_y * 1.2f + (Button_h * i), Button_w * 3, Button_h * 0.5f),Server_Data*.gameName))*

Network.Connect(Server_Data*);
