我经历了一个关于如何实现Unity的NetworkTransport的广泛教程，当我跟随时，这一切都很有意义但是一旦我完成并且我开始做出改变，一切都在我身边。我需要一些帮助来了解服务器和客户端脚本之间的关系如何以及如何添加其他变量以发送到服务器/客户端。
从脚本当前的位置开始，我在客户端添加了两个额外的变量（一个Texture2D和一个字符串），这些变量被添加到我的播放器类并传递给服务器和其他客户端。
我已经在客户端脚本中启动了这两个额外的变量添加到我的Player类，并将相同的变量添加到服务器脚本上的ServerClient类。然后在SpawnPlayer函数的客户端脚本中，我传递了这两个额外的变量，但是我对最初如何创建正确的字符串以保存这两个新变量感到困惑。如果有人能指出我正确的方向，那将是非常有帮助的。谢谢！

简单地说，序列化并发送数据然后接收并反序列化它。如果您仍然感到困惑，请阅读以下步骤：
在您的示例中，您要发送* {
box-sizing: border-box;
}
body {
padding: 0;
margin: 0;
}
nav {
border-bottom: 1px solid #ddd;
font-family: 'Roboto';
display: flex;
justify-content: space-between;
font-weight: 300;
}
/*
nav:after {
content: " ";
display: block;
clear: both;
height: 0.01px;
}
*/
.container {
display: flex;
}
.nav-btn {
height: 4em;
padding: 0em 1em;
border-right: 1px solid grey;
display: flex;
min-width: 100px;
justify-content: center;
align-items: center;
}
.no-border {
border-right: 0px solid white;
}
img {
height: 60%;
}
.fa {
color: #ccc;
}
nav .search {
height: 4.5em;
width: 20em;
font-family: 'Roboto';
font-weight: 400;
border-style: none;
text-indent: 1em;
}
nav .search:focus {
outline-style: none;
}
nav .btn {
font-weight: 400;
color: grey;
border: 2px solid #aaa;
padding: 0.5em 0.7em;
letter-spacing: 0.01em;
}
.b-a-host {
white-space: nowrap;
}
.nav-btn.hoverback:hover {
cursor: pointer;
background-color: #f8f8f8;
}
@media (max-width:500px) {
nav {
flex-direction: column;
}
}和<link href='https://fonts.googleapis.com/css?family=Roboto:300,400' rel='stylesheet' type='text/css'>
<nav>
<div class='container'>

发送方：
1 。第一步是表示要在类或结构中发送的数据。
您不希望直接向此类添加Texture2D。您需要将其存储为字节数组。此示例使用string来执行此操作。您还可以将其转换为PNG或JPEG字节数组以减小大小。
Texture2D2 .Serialize要发送的数据：
要发送的数据示例：
Texture2D.GetRawTextureData()从Texture2D和字符串：
创建结构的新实例[Serializable]
public class SendStructure
{
public byte[] texture;
public string message;
public SendStructure(Texture2D texture, string message)
{
this.texture = texture.GetRawTextureData();
this.message = message;
}
}
序列化到内存
Texture2D textureToSend = new Texture2D(4, 4);
string stringToSend = "Hello";
3 。发送到网络
SendStructure sendStructure = new SendStructure(textureToSend, stringToSend);
接收方：
4 。从网络接收
MemoryStream memStream = new MemoryStream();
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(memStream, sendStructure);
//Array data to send over network
byte[] serializedStructure = memStream.ToArray();
5 .De-serialize收到的数据：
NetworkTransport.Send(hostID, sc.connectionID, channelID, serializedStructure, serializedStructure.Length, out error);
6 。访问收到的数据：
检索int outHostId;
int outConnectionId;
int outChannelId;
int receivedSize;
byte error;
//Where to store received data
byte[] buffer = new byte[400000];
NetworkEventType evt = NetworkTransport.Receive(out outHostId, out outConnectionId, out outChannelId, buffer, buffer.Length, out receivedSize, out error);
：
switch (evt)
{
case NetworkEventType.DataEvent:
{
//De-Serialize recevied byte array into memory
MemoryStream stream = new MemoryStream(buffer, 0, receivedSize);
IFormatter formatter = new BinaryFormatter();
stream.Seek(0, SeekOrigin.Begin);
//Received data now stored as SendStructure
SendStructure receivedStructure = formatter.Deserialize(stream) as SendStructure;
break;
}
}
检索string：
string receivedString = receivedStructure.message;
