RakNet发送与接收数据

Common mistake!
When writing the first byte to a bitstream, be sure to cast it to (MessageID) or (unsigned char). If you just write the enumeration directly you will be writing a full integer (4 bytes).
Right:
bitStream->Write((MessageID)ID_SET_TIMED_MINE);

Wrong: 
bitStream->Write(ID_SET_TIMED_MINE);

In the second case, RakNet will see the first byte is 0, which is reserved internally to ID_INTERNAL_PING, and you will never get it.

void DoMyPacketHandler(Packet *packet)
{
	Bitstream myBitStream(packet->data, packet->length, false); // The false is for efficiency so we don‘t make a copy of the passed data
	myBitStream.Read(useTimeStamp);
	myBitStream.Read(timeStamp);
	myBitStream.Read(typeId);
	myBitStream.Read(x);
	myBitStream.Read(y);
	myBitStream.Read(z);
	
	myBitStream.Read(networkID); // In the struct this is NetworkID networkId
	myBitStream.Read(systemAddress); // In the struct this is SystemAddress systemAddress
}
