Unity C# E-learning （ 11、 ... and ）—— Custom protocol generation tool
In the development of online games , Agreements are essential , A game may have many agreements , But the agreement is highly repeatable , And both the front end and the back end need , It is obviously unrealistic to complete it manually , Our protocol can be generated through common configuration
One . Protocol profile
- Here the Xml To configure the protocol
<?xml version="1.0" encoding="utf-8"?>
<messages>
<!-- Enumeration type -->
<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>
<!-- Data structure type -->
<data name="PlayerData" namespace="GamePlayer">
<field name="id" type="int"/>
<field name="atk" type="float"/>
<field name="sex" type="bool"/>
<field name="lev" type="long"/>
<field name="arrays" type="array" T="int"/>
<field name="list" type="list" T="int"/>
<field name="dic" type="dic" Tkey="int" TValue="string"/>
</data>
<!-- Message type -->
<message name="PlayerMsg" id="1001" namespace="GamePlayer">
<field name="playerID" type="int" />
<field name="data" type="PlayerData"/>
</message>
<message name="HeartMsg" id="1002" namespace="GameSystem"/>
</messages>
Two . Test read Xml The configuration file
private void Start()
{
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(Application.dataPath + "/Src/Lesson32/Lesson32.xml");
XmlNode rootNode = xmlDocument.SelectSingleNode("messages");
if (rootNode == null)
return;
// Read enumeration
XmlNodeList enumNodeList = rootNode.SelectNodes("enum");
if (enumNodeList == null)
return;
foreach (XmlNode enumNode in enumNodeList)
{
if (enumNode?.Attributes == null)
continue;

Debug.Log(" Namespace :" + enumNode.Attributes["namespace"].Value);
XmlNodeList fieldNodeList = enumNode.SelectNodes("field");
if (fieldNodeList == null)
continue;
foreach (XmlNode fieldNode in fieldNodeList)
{
if (fieldNode?.Attributes == null)
continue;
Debug.Log(fieldNode.Attributes["name"].Value);
if (!string.IsNullOrEmpty(fieldNode.InnerText))
Debug.Log(fieldNode.InnerText);
}
}
// Read custom Data Class data
XmlNodeList dataNodeList = rootNode.SelectNodes("data");

}
3、 ... and . according to Enum Configure and generate the corresponding C# Code

5、 ... and . according to Msg Configure to generate corresponding code
- According to the above Data Configuring the generated data class is similar to
- Modify the inherited base class to MsgBase
- modify GetLength() Method , Let the minimum length be 8
- modify ToArray() Method , Write message ID And message length
- Add return MsgID Methods
6、 ... and . test
private void Start()
