一个简单的游戏框架:网络方案
代码:https://github.com/HushengStudent/myGameFramework
1、C# socket编程:
使用socket,通过ip+端口,连接服务器和客户端,传递数据;
//client:
//创建Socket
_socket = new Socket(addressFamily, SocketType.Stream, ProtocolType.Tcp);
//连接服务器
_socket.BeginConnect(_ipAddress, _port, ConnectCallback, param);
//发送数据
_socket.BeginSend(buffer, offset, size, SocketFlags.None, SendCallback, param);
//server:
Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 10000);
serverSocket.Bind(ipEndPoint);
serverSocket.Listen(0);
serverSocket.BeginAccept(AcceptCallBack, serverSocket);
2、数据的序列化
数据序列化使用了Protobuff:
public static void Serialize<T>(Session session, MemoryStream destination, T packet) where T : Packet
{
byte[] idBytes = ConverterUtility.GetBytes(packet.GetPacketId());
destination.Write(idBytes, 0, idBytes.Length);
packet.Serialize(destination);
ProtoRegister.ReturnPacket(packet);
}
public static Packet Deserialize(Session session, MemoryStream source, out object customErrorData)
{
customErrorData = null;
long begin = source.Position;
byte[] buffer = new byte[4];
source.Read(buffer, 0, sizeof(int));
int id = ConverterUtility.GetInt32(buffer);
Packet packet = ProtoRegister.GetPacket(id);
packet.DeSerialize(source);
return packet;
}
3、数据包设计
长度(int)+数据
4、协议设计
协议基类:
public abstract class Packet
{
//TODO:协议ID优化为UShort,减少数据;
public abstract int GetPacketId();
public abstract void Serialize(MemoryStream stream);
public abstract void DeSerialize(MemoryStream stream);
public abstract void Process();
}
举个栗子,登录协议:
public class Packet_LoginRequest : Packet
{
private LoginRequest data = new LoginRequest();
public LoginRequest Data { get { return data; } }
public override int GetPacketId()
{
return 10011;
}
public override void DeSerialize(MemoryStream stream)
{
data = ProtoBuf.Serializer.Deserialize<LoginRequest>(stream);
}
public override void Serialize(MemoryStream stream)
{
ProtoBuf.Serializer.Serialize<LoginRequest>(stream, data);
}
public override void Process()
{
Process_LoginRequest.Process(this);
}
}
测试:
Packet_LoginRequest req = new Packet_LoginRequest();
req.Data.id = 1001;
req.Data.name = "HushengStudent";
NetMgr.Instance.Send<Packet_LoginRequest>(req);
Packet_LoginResponse rsp = new Packet_LoginResponse();
rsp.Data.id = 123;
session.Send<Packet_LoginResponse>(rsp);
Console.WriteLine(string.Format("send to client: {0} !",rsp.Data.id));
