Question

[我在c＃工作]

为了确定天气，设备应该成为仅具有本地客户端或客户端的服务器（对于无主服务器的网络），我需要先找出该设备是否还有其他可用服务器，然后再转换为服务器本地客户端，如果没有通过从服务器接收NetworkDiscovery广播来加入另一个客户端设备 - 目前我无法让客户端从服务器接收广播。

我创建了两个空的游戏对象，每个都有脚本，一个脚本使其成为服务器，应该通过NetworkDiscovery.StartAsServer()通过NetworkDiscovery进行广播，但目前我的客户NetworkDiscovery.StartAsClient()已经设置了到OnRecievedBroadcast()没有得到被调用的using UnityEngine; using System.Collections; using UnityEngine.Networking; public class SearchForServers : MonoBehaviour { bool serverIsFound; NetworkDiscovery NetworkDiscovery; // Use this for initialization void Start () { serverIsFound = false; NetworkClient Client = new NetworkClient(); NetworkDiscovery = gameObject.AddComponent<NetworkDiscovery>(); NetworkDiscovery.Initialize(); NetworkDiscovery.StartAsClient(); } void OnRecievedBroadcast(string fromAdress, string data) { serverIsFound = true; } // Update is called once per frame void Update () { Debug.Log("Server Found = " + serverIsFound); } }函数，因此没有从服务器接收广播。

下面显示的两个脚本是客户端和服务器：

客户 -

    using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class CreateServer : MonoBehaviour
{
    bool create;
    int minPort = 10000;
    int maxPort = 10010;
    int defaultPort = 10000;
    NetworkDiscovery NetworkDiscovery;

    void Start()
    {
        create = true;
        if (create == true)
        {
            int serverPort = createServer();
            if (serverPort != -1)
            {
                Debug.Log("Server created on port : " + serverPort);
            }
            else
            {
                Debug.Log("Failed to create Server");
            }
        }
        NetworkDiscovery = gameObject.AddComponent<NetworkDiscovery>();
        NetworkDiscovery.Initialize();
        NetworkDiscovery.StartAsServer();
    }


    //Creates a server then returns the port the server is created with. Returns -1 if server is not created
    int createServer()
    {
        int serverPort = -1;
        //Connect to default port

      bool serverCreated = NetworkServer.Listen(defaultPort);
        if (serverCreated)
        {
            serverPort = defaultPort;
            Debug.Log("Server Created with default port");
        }
        else
        {
            Debug.Log("Failed to create with the default port");
            //Try to create server with other port from min to max except the default port which we trid already
            for (int tempPort = minPort; tempPort <= maxPort; tempPort++)
            {
                //Skip the default port since we have already tried it
                if (tempPort != defaultPort)
                {
                    //Exit loop if successfully create a server
                    if (NetworkServer.Listen(tempPort))
                    {
                        serverPort = tempPort;
                        break;
                    }

                    //If this is the max port and server is not still created, show, failed to create server error
                    if (tempPort == maxPort)
                    {
                        Debug.LogError("Failed to create server");
                    }
                }
            }
        }
        return serverPort;
    }
}

服务器 -

@objects = Object.near(location, 50)

这些是带有调试日志记录的控制台日志

首先，您将每个服务器和客户端脚本命名为相同的名称。您在服务器代码中不需要OnRecievedBroadcast。您只需要在客户端代码中使用它。由于您没有覆盖OnRecievedBroadcast，因此未在客户端调用NetworkDiscovery。你必须覆盖它。

以下是一个简单的发现代码 ：

<强>客户端：

public class NetClient : NetworkDiscovery
{

    void Start()
    {
        startClient();
    }

    public void startClient()
    {
        Initialize();
        StartAsClient();
    }

    public override void OnReceivedBroadcast(string fromAddress, string data)
    {
         Debug.Log("Server Found");
    }
}

服务器：

public class NetServer : NetworkDiscovery { // Use this for initialization void Start() { Application.runInBackground = true; startServer(); } //Call to create a server public void startServer() { int serverPort = createServer(); if (serverPort != -1) { Debug.Log("Server created on port : " + serverPort); broadcastData = serverPort.ToString(); Initialize(); StartAsServer(); } else { Debug.Log("Failed to create Server"); } } int minPort = 10000; int maxPort = 10010; int defaultPort = 10000; //Creates a server then returns the port the server is created with. Returns -1 if server is not created private int createServer() { int serverPort = -1; //Connect to default port bool serverCreated = NetworkServer.Listen(defaultPort); if (serverCreated) { serverPort = defaultPort; Debug.Log("Server Created with deafault port"); } else { Debug.Log("Failed to create with the default port"); //Try to create server with other port from min to max except the default port which we trid already for (int tempPort = minPort; tempPort <= maxPort; tempPort++) { //Skip the default port since we have already tried it if (tempPort != defaultPort) { //Exit loop if successfully create a server if (NetworkServer.Listen(tempPort)) { serverPort = tempPort; break; } //If this is the max port and server is not still created, show, failed to create server error if (tempPort == maxPort) { Debug.LogError("Failed to create server"); } } } } return serverPort; } }

createServer()函数是您上一个问题的函数。我不认为您可以在编辑器中同时运行服务器和客户端代码。

为了进行测试，您必须在您的电脑上构建代码并启用服务器代码/ NetServer。运行构建的程序然后从编辑器运行客户端/ NetClient代码。这应该在服务器上发现游戏。
