65.消息处理-自定义协议生成工具-协议消息生成-生成消息类
65.1 知识点
对比消息类和数据结构类的不同
类名和继承
public class PlayerMessage : BaseMessage
获得字节数组方法多了消息ID长度和消息体长度8个字节
public override int GetBytesNum()
{
return
4 + // 消息ID的长度
4 + // 消息体的长度
4 + // playerID的字节数组长度
playerData.GetBytesNum(); // playerData的字节数组长度
}
序列化方法要先写消息ID再写消息体长度
public override byte[] Writing()
{
int index = 0;
int bytesNum = GetBytesNum();
byte[] bytes = new byte[bytesNum];
// 先写消息ID
WriteInt(bytes, GetID(), ref index);
// 写入消息体的长度
WriteInt(bytes, bytesNum - 8, ref index);
// 写这个消息的成员变量
WriteInt(bytes, playerID, ref index);
WriteData(bytes, playerData, ref index);
return bytes;
}
反序列化由于我们是在外部解析消息ID和消息体长度的，所以和数据结构类一致
获得定义消息ID的方法
/// <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;
}
观察xml配置
- <!--消息类类配置规则 包含 消息ID 类名 命名空间 变量类型 变量名-->
<message id="1001" name="PlayerMessage" namespace="GamePlayer">
<field type="int" name="playerID"/>
<field type="PlayerData" name="data"/>
</message>
<message id="1002" name="HeartMessage" namespace="GameSystem"/>
在GenerateCSharp类中定义生成消息类方法，并在ProtocolTool中调用
[MenuItem("ProtocolTool/生成C#脚本")]
private static void GenerateCSharp()
{
// 读取xml相关的信息
// XmlNodeList list = GetNodes("enum");
// 根据这些信息 去拼接字符串 生成对应的脚本
// 生成对应的枚举脚本
generateCSharp.GenerateEnum(GetNodes("enum"));
// 生成对应的数据结构类脚本
generateCSharp.GenerateData(GetNodes("data"));
// 生成对应的消息类脚本
generateCSharp.GenerateMsg(GetNodes("message"));
// 刷新编辑器界面 让我们可以看到生成的内容 不需要手动进行刷新了
AssetDatabase.Refresh();
}
实现生成消息类方法，可以在生产数据结构类方法的基础上改
// 生成消息类
public void GenerateMsg(XmlNodeList nodes)
{
string idStr = "";
string namespaceStr = "";
string classNameStr = "";
string fieldStr = "";
string getBytesNumStr = "";
string writingStr = "";
string readingStr = "";
foreach (XmlNode dataNode in nodes)
{
// 消息ID
idStr = dataNode.Attributes["id"].Value;
// 命名空间
namespaceStr = dataNode.Attributes["namespace"].Value;
// 类名
classNameStr = dataNode.Attributes["name"].Value;
// 读取所有字段节点
XmlNodeList fields = dataNode.SelectNodes("field");
// 通过这个方法进行成员变量声明的拼接 返回拼接结果
fieldStr = GetFieldStr(fields);
// 通过某个方法 对GetBytesNum函数中的字符串内容进行拼接 返回结果
getBytesNumStr = GetGetBytesNumStr(fields);
// 通过某个方法 对Writing函数中的字符串内容进行拼接 返回结果
writingStr = GetWritingStr(fields);
// 通过某个方法 对Reading函数中的字符串内容进行拼接 返回结果
readingStr = GetReadingStr(fields);
string dataStr = "using System;\r\n" +
"using System.Collections.Generic;\r\n" +
"using System.Text;\r\n" +
$"namespace {namespaceStr}\r\n" +

"\t\t\treturn " + idStr + ";\r\n" +

"}";
// 保存为 脚本文件
// 保存文件的路径
string path = SAVE_PATH + namespaceStr + "/Msg/";
// 如果不存在这个文件夹 则创建
if (!Directory.Exists(path))
Directory.CreateDirectory(path);
// 字符串保存 存储为枚举脚本文件
File.WriteAllText(path + classNameStr + ".cs", dataStr);
}
