m_connection.UnregisterReceivedCallback (m_receiveCallBack); 发送消息NetOutgoingMessage nm connection.CreateMessage (bytesLength);
nm.Write (bytes, 0, bytesLength);
m_connection.SendMessage (nm, (NetDeliveryMethod)channelType, channel); NetDeliveryMethod有以下几类UnReliable不可靠传输顺序和丢包都不能保证UnReliableSequence不可靠传输按顺序接收 旧包直接丢弃ReliableUnOrdered可靠传输不保证顺序但是不会丢包ReliableSequence可靠传输和UnReliableSequence但是有一个缓冲窗口超过缓冲范围的包会丢弃ReliableOrdered可靠传输不丢包保证顺序 接收消息void OnReceiveMessage(object state) { NetIncomingMessage im; while ((im m_connection.ReadMessage()) !
