Question

我开始一个新游戏，然后尝试在其上实现网络。我启动服务器，可以将客户端连接到该服务器，但是，我想获取网络客户端ipadress。但这给了我超出范围的错误

有问题的错误就在网上 clientip = Network.connections [0] .ipAddress;

这是错误

IndexOutOfRangeException：数组索引超出范围。菜单。更新（）（位于Assets / net / menu.cs：72）

这是我当前的代码

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class menu : MonoBehaviour {

public string IP= "127.0.0.1";
public int Port = 25001;
public bool switchoffnetwork;
public GameObject btnon;
public GameObject btnoff;
public string username = "wizard";
public int idst = 0;
public string ID;
public bool IsClientConnectx= false;
public bool IsServerConnectx= false;
public string clientip;

void OnGUI () 
{

    if (switchoffnetwork == true) 
    {
        if (Network.peerType == NetworkPeerType.Disconnected) {
            if (GUI.Button (new Rect (100, 100, 100, 25), "Start Client")) {
                Network.Connect (IP, Port);
            }
            if (GUI.Button (new Rect (100, 125, 100, 25), "Start Server")) {
                Network.InitializeServer (10, Port);

            }
        } else {
            if (Network.peerType == NetworkPeerType.Client) {
                GUI.Label (new Rect (100, 100, 100, 25), "Connect Player");
                if (GUI.Button (new Rect (100, 125, 100, 25), "Logout")) {
                    Network.Disconnect (250);
                }
                if (GUI.Button (new Rect (100, 150, 140, 25), "Disconnect Player"))
                if (Network.connections.Length > 0) {
                    Debug.Log("Disconnecting: " + Network.connections[0].ipAddress + ":" + Network.connections[0].port);
                    Network.CloseConnection(Network.connections[0], true);
                }
            }
            if (Network.peerType == NetworkPeerType.Server) {
                GUI.Label (new Rect (100, 100, 100, 25), "Server");
                GUI.Label (new Rect (100, 125, 100, 25), "Connections: " + Network.connections.Length);
                if (GUI.Button (new Rect (100, 150, 100, 25), "Logout")) {
                    Network.Disconnect (250);
                }
            }
        }

    }
}
public void onswitch()
{
    switchoffnetwork = true;
    btnon.SetActive (false);
    btnoff.SetActive (true);
}
public void onswitchbtn()
{
    switchoffnetwork = false;
    btnon.SetActive (true);
    btnoff.SetActive (false);
}

void Update ()
{
    clientip = Network.connections[0].ipAddress;
    if (Network.peerType == NetworkPeerType.Disconnected) 
    {

        Debug.Log("Player Have disconected" + clientip);
    }

}

}

尝试获取网络客户端IP地址时出现IndexOutOfRangeException
