1、消息（协议）规则制定
数据结构类基类
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine;public abstract class BaseData
{/// <summary>/// 用于子类重写的 获取字节数组容器大小的方法/// </summary>/// <returns></returns>public abstract int GetBytesNum();/// <summary>/// 把成员变量序列化为 对应的字节数组/// </summary>/// <returns></returns>public abstract byte[] Writing();/// <summary>/// 把二进制字节数组 反序列化 到成员变量当中/// </summary>/// <param name="bytes">反序列化使用的字节数组</param>/// <param name="beginIndex">从该字节数组的第几个位置开始解析 默认是 0</param>public abstract int Reading(byte[] bytes, int beginIndex = 0);/// <summary>/// 存储int类型变量到指定的字节数组/// </summary>/// <param name="bytes">指定字节数组</param>/// <param name="value">具体的int值</param>/// <param name="index">每次存储后用于记录当前索引位置的变量</param>protected void WriteInt(byte[] bytes, int value, ref int index){BitConverter.GetBytes(value).CopyTo(bytes, index);index += sizeof(int);}protected void WriteShort(byte[] bytes, short value, ref int index){BitConverter.GetBytes(value).CopyTo(bytes, index);index += sizeof(short);}protected void WriteLong(byte[] bytes, long value, ref int index){BitConverter.GetBytes(value).CopyTo(bytes, index);index += sizeof(long);}protected void WriteFloat(byte[] bytes, float value, ref int index){BitConverter.GetBytes(value).CopyTo(bytes, index);index += sizeof(float);}protected void WriteByte(byte[] bytes, byte value, ref int index){bytes[index] = value;index += sizeof(byte);}protected void WriteBool(byte[] bytes, bool value, ref int index){BitConverter.GetBytes(value).CopyTo(bytes, (int)index);index += sizeof(bool);}protected void WriteString(byte[] bytes, string value, ref int index){//先存储string字节数组长度byte[] strBytes = Encoding.UTF8.GetBytes(value);int num = strBytes.Length;BitConverter.GetBytes(num).CopyTo(bytes, index);index += sizeof(int);//在存储 string 字节数组strBytes.CopyTo(bytes, index);index += num;}protected void WriteData(byte[] bytes, BaseData data, ref int index){data.Writing().CopyTo(bytes, index);index += data.GetBytesNum();}/// <summary>/// 根据字节数组读取整形/// </summary>/// <param name="bytes">读取数组</param>/// <param name="index">开始读取的索引位置</param>/// <returns></returns>protected int ReadInt(byte[] bytes, ref int index){int value = BitConverter.ToInt32(bytes, index);index += sizeof(int);return value;}protected short ReadShort(byte[] bytes, ref int index){short value = BitConverter.ToInt16(bytes, index);index += sizeof(short);return value;}protected long ReadLong(byte[] bytes, ref int index){long value = BitConverter.ToInt64(bytes, index);index += sizeof(long);return value;}protected float ReadFloat(byte[] bytes, ref int index){float value = BitConverter.ToSingle(bytes, index);index += sizeof(float);return value;}protected byte ReadByte(byte[] bytes, ref int index){byte b = bytes[index];index++;return b;}protected bool ReadBool(byte[] bytes, ref int index){bool value = BitConverter.ToBoolean(bytes, index);index += sizeof(bool);return value;}protected string ReadString(byte[] bytes, ref int index){int length = BitConverter.ToInt32(bytes, index);index += sizeof(int);string value = Encoding.UTF8.GetString(bytes, index, length);index += length;return value;}protected T ReadData<T>(byte[] bytes, ref int index) where T : BaseData, new(){T value = new T();index += value.Reading(bytes, index);return value;}}
消息类基类
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class BaseMsg : BaseData
{public override int GetBytesNum(){throw new System.NotImplementedException();}public override int Reading(byte[] bytes, int beginIndex = 0){throw new System.NotImplementedException();}public override byte[] Writing(){throw new System.NotImplementedException();}public virtual int GetID(){return 0;}
}
2、消息类使用方法
2.1 创建数据类，继承数据结构基类
根据成员变量实现方法GetBytesNum，Reading，Writing
using System.Collections;
using System.Collections.Generic;
using System.Text;
using UnityEngine;/// <summary>
/// 玩家数据类
/// </summary>
public class PlayerData : BaseData
{public string name;public int atk;public int lev;public override int GetBytesNum(){return 4 + 4 + 4 + Encoding.UTF8.GetBytes(name).Length;}public override int Reading(byte[] bytes, int beginIndex = 0){int index = beginIndex;name = ReadString(bytes, ref index);atk = ReadInt(bytes, ref index);lev = ReadInt(bytes, ref index);return index - beginIndex;}public override byte[] Writing(){int index = 0;byte[] bytes = new byte[GetBytesNum()];WriteString(bytes, name, ref index);WriteInt(bytes, atk, ref index);WriteInt(bytes, lev, ref index);return bytes;}
}
2.2 创建消息类，继承消息类基类
消息类需要根据成员变量实现方法GetBytesNum，Reading，Writing，GetID
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerMsg : BaseMsg
{public int playerID;public PlayerData playerData;public override byte[] Writing(){int index = 0;int bytesNum = GetBytesNum();byte[] bytes = new byte[bytesNum];//先写消息IDWriteInt(bytes, GetID(), ref index);//写入消息体长度 我们-8的目的 是只存储消息体的长度 前面8个字节 是我们字节定制的规则 解析时按照这个规则处理就行了WriteInt(bytes, bytesNum - 8, ref index);//写消息的成员变量WriteInt(bytes, playerID, ref index);WriteData(bytes, playerData, ref index);return bytes;}public override int Reading(byte[] bytes, int beginIndex = 0){//反序列化不需要取解析ID 因为在这一步之前 就应该把ID反序列化出来//用来判断到底使用哪一个自定义类来反序列化int index = beginIndex;playerID = ReadInt(bytes, ref index);playerData = ReadData<PlayerData>(bytes, ref index);return index - beginIndex;}public override int GetBytesNum(){return 4 + //消息ID长度4 + //消息体的长度4 + //palyerIDplayerData.GetBytesNum(); //playerData}/// <summary>/// 自定义的消息ID 主要用于区分是哪一个消息类/// </summary>/// <returns></returns>public override int GetID(){return 1001;}
}
2.3 发送消息，首先创建消息类实例，使用方法Writing()获取字节数组，将字节数组发送出去
PlayerMsg ms = new PlayerMsg();ms.playerID = 123123;ms.playerData = new PlayerData();ms.playerData.name = "hellow";ms.playerData.atk = 0;ms.playerData.lev = 1;ms.Writing();2.4 接受消息，收到消息字节数组，先解析消息ID，根据ID使用具体消息类Reading()解析消息
//首先解析消息的IDint msgID = BitConverter.ToInt32(receiveBytes, 0);switch (msgID){case 1001:PlayerMsg msg = new PlayerMsg();msg.Reading(receiveBytes, 4);Debug.Log(msg.playerID);Debug.Log(msg.playerData.name);Debug.Log(msg.playerData.atk);Debug.Log(msg.playerData.lev);break;default:break;}3、创建配置工具自动生成脚本
3.1 使用xml文件进行配置，规则如下
<?xml version="1.0" encoding="UTF-8"?>
<messages><!--枚举配置规则--><enum name="E_PLAYER_TYPE" namespace="GamePlayer"><field name="MAIN">1</field><field name="OTHER"/></enum><enum name="E_MONSTER_TYPE" namespace="GameMonster"><field name="NORMAL">2</field><field name="BOSS"/></enum><!--数据结构类配置规则--><data name="PlayerData" namespace="GamePlayer"><field type="int" name="id" /><field type="float" name="atk" /><field type="long" name="lev" /><field type="array" name="arrays" /><field type="list" T="int" name="list" /><field type="dic" Tkey="int" Tvalue="string" name="dic" /></data><!--消息类配置规则--><message id="1001" name="PlayerMeg" namespace="GamePlayer"><field type="int" name="playerID" /><field type="PlayerData" name="data" /></message><message id="1002" name="HeartMsg" namespace="GameSystem"/>
</messages>3.2 工具类功能实现脚本
ProtocolTool
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using UnityEditor;
using UnityEngine;public class ProtocolTool

3.3 工具使用步骤
1）创建xml配置文件，根据需要使用的消息类进行配置
<?xml version="1.0" encoding="UTF-8"?>
<messages><!--枚举配置规则--><enum name="E_PLAYER_TYPE" namespace="GamePlayer"><field name="MAIN">1</field><field name="OTHER"/></enum><enum name="E_HERO_TYPE" namespace="GamePlayer"><field name="MAIN"/><field name="OTHER"/></enum><enum name="E_MONSTER_TYPE" namespace="GameMonster"><field name="NORMAL">2</field><field name="BOSS"/></enum><!--数据结构类配置规则--><data name="PlayerData" namespace="GamePlayer"><field type="int" name="id" /><field type="float" name="atk" /><field type="bool" name="sex" /><field type="long" name="lev" /><field type="array" data="int" name="arrays" /><field type="list" T="int" name="list" /><field type="dic" Tkey="int" Tvalue="string" name="dic" /><field type="enum" data="E_HERO_TYPE" name="hereType"/></data><!--消息类配置规则--><message id="1001" name="PlayerMeg" namespace="GamePlayer"><field type="int" name="playerID" /><field type="PlayerData" name="data" /></message><message id="1002" name="HeartMsg" namespace="GameSystem"/>
</messages>2）在ProtocolTool工具类中修改PROTO_INFO_PATH，根据自己的xml配置文件路径进行
3）在GeneraterCSharp工具类中修改SAVA_PATH，设置文件生成路径
4）在unity中点击按钮ProtocolTool/生成C#脚本，完成脚本生成
