🚩 Import

• 下载SKFramework框架，导入到Unity中；

• 在框架Package Manager中搜索并下载导入Socket模块；
  
• Package包中包含Server服务端内容以及protogen工具，将其解压到工程外；

🚀 protogen使用方法

• 编写的.proto文件放入proto文件夹中；

• 打开run.bat文件，编辑编译指令；

• 运行run.bat文件，生成后的.cs脚本在cs文件夹中，将其放入到Unity中即可；

注：.proto文件编译为.cs脚本后，该脚本一般不轻易改动。

• 如果有大量的.proto文件需要编译，编辑编译指令可能会比较繁琐，因此可以使用自定义的工具Protogen Helper来自动创建run.bat文件。

代码如下：

using System.IO;
using UnityEngine;
using UnityEditor;
using System.Text;
using System.Diagnostics;

namespace Mutiplayer
{
    /// <summary>
    /// Proto通信协议类编译工具
    /// </summary>
    public class ProtogenHelper : EditorWindow
    {
        [MenuItem("Multiplayer/Protogen Helper")]
        public static void Open()
        {
            var window = GetWindow<ProtogenHelper>("Protogen Helper");
            window.maxSize = new Vector2(1000f, 60f);
            window.minSize = new Vector2(200f, 60f);
            window.Show();
        }

        //根路径
        private string rootPath;
        private const string prefsKey = "Protogen.exe Path";

        private void OnEnable()
        {
            rootPath = EditorPrefs.HasKey(prefsKey) ? EditorPrefs.GetString(prefsKey) : string.Empty;
        }

        private void OnGUI()
        {
            GUILayout.Label("protogen.exe所在路径:");
            GUILayout.BeginHorizontal();
            {
                string path = GUILayout.TextField(rootPath);
                if (path != rootPath)
                {
                    rootPath = path;
                    EditorPrefs.SetString(prefsKey, rootPath);
                }
                if (GUILayout.Button("Browse", GUILayout.Width(55f)))
                {
                    path = EditorUtility.OpenFolderPanel("选择路径", rootPath, null);
                    if (path != rootPath)
                    {

                        EditorPrefs.SetString(prefsKey, rootPath);
                    }
                }
            }
            GUILayout.EndHorizontal();

            if (GUILayout.Button("Create .bat"))
            {
                string protoPath = rootPath + "/proto";
                if (!Directory.Exists(protoPath))
                {
                    UnityEngine.Debug.Log($"<color=red>文件夹不存在</color> {protoPath}");
                    return;
                }
                string csPath = rootPath + "/cs";

                {
                    Directory.CreateDirectory(csPath);
                }
                DirectoryInfo di = new DirectoryInfo(protoPath);
                //获取所有.proto文件信息
                FileInfo[] protos = di.GetFiles("*.proto");
                //使用StringBuilder拼接字符串
                StringBuilder sb = new StringBuilder();
                //遍历
                for (int i = 0; i < protos.Length; i++)
                {
                    string proto = protos[i].Name;
                    //拼接编译指令
                    sb.Append(rootPath + @"/protogen.exe -i:proto\" + proto + @" -o:cs\" + proto.Replace(".proto", ".cs") + "\r\n");
                }
                sb.Append("pause");

                //生成".bat文件"
                string batPath = $"{rootPath}/run.bat";
                File.WriteAllText(batPath, sb.ToString());
                //打开该文件夹
                Process.Start(rootPath);
            }
        }
    }

🪐 客户端接口

• Connect： 连接服务端；

/// <summary>
/// 连接服务端
/// </summary>
/// <param name="ip">服务器IP地址</param>
/// <param name="port">端口</param>
public void Connect(string ip, int port)

• Send：发送数据；

/// <summary>
/// 发送数据
/// </summary>
/// <param name="proto">协议</param>
public void Send(IExtensible proto)

• Close：关闭与服务端的连接；

/// <summary>
/// 关闭连接
/// </summary>
public void Close()

🌈 服务端接口

• 向单个客户端发送数据；

/// <summary>
/// 向客户端发送协议(单点发送)
/// </summary>
/// <param name="client">客户端</param>
/// <param name="proto">协议</param>
public static void Send(Client client, IExtensible proto)

• 向所有客户端发送数据；

/// <summary>
/// 向所有客户端发送协议(广播)
/// </summary>
/// <param name="proto">协议</param>
public static void Send(IExtensible proto)

• 向指定客户端之外的所有客户端发送数据；

/// <summary>
/// 向指定客户端之外的所有客户端发送协议
/// </summary>
/// <param name="proto">协议</param>
/// <param name="except">不需要发送的客户端</param>
public static void Send(IExtensible proto, Client except)

• 关闭指定客户端的连接；

/// <summary>
/// 关闭客户端连接
/// </summary>
/// <param name="client">客户端</param>
public static void Close(Client client)

🧭 数据处理

根据解析出的协议名来调用相应的处理方法：

以上是服务端对ProtoTest类型协议的处理示例，服务端通过Send将该消息转发给所有客户端。
