Unity如何使用NetworkDiscovery从客户端查找服务器

[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），我需要在转向使用本地客户端的服务器之前找出该设备是否还有其他可用服务器。不是通过从服务器接收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，一个脚本使它成为一个服务器，应该通过NetworkDiscovery.StartAsServer()从其NetworkDiscovery广播，但目前我的客户端的NetworkDiscovery已经设置为NetworkDiscovery.StartAsClient()没有得到OnRecievedBroadcast()函数被调用因此不接收来自服务器的广播。

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 SearchForServers : MonoBehaviour { bool serverIsFound; NetworkDiscovery NetworkDiscovery; // Use this for initialization void Start () { serverIsFound = false; NetworkClient Client = new NetworkClient(); NetworkDiscovery = gameObject.AddComponent(); 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); } } 

服务器 –

  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.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; } } 

这些是带有调试日志记录的控制台日志

感谢您的阅读，我希望您能够意识到我哪里出错或者确实如何完成所述任务。 @程序员

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

这是一个简单的发现代码 ：

客户 ：

 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。

要进行测试，您必须在启用了服务器代码/ NetServer的PC中构建代码。 然后从编辑器运行构建的程序，您可以运行客户端/ NetClient代码。 这应该发现服务器上的游戏。
