hello, I need help to understand about sending and receiving bytes, if anyone can explain this I will be grateful!

I'm passing code from version 0x to 1.3 and I need to understand about bytes, this is the 0x function,
C++:
void ProtocolGame::reloadCreature(const Creature* creature)
{
    if(!canSee(creature))
        return;

    // we are cheating the client in here!
    uint32_t stackpos = creature->getTile()->getClientIndexOfThing(player, creature);
    if(stackpos >= 10)
        return;

    NetworkMessage_ptr msg = getOutputBuffer();
    if(msg)
    {
        TRACK_MESSAGE(msg);
        std::list<uint32_t>::iterator it = std::find(knownCreatureList.begin(), knownCreatureList.end(), creature->getID());
        if(it != knownCreatureList.end())
        {
            RemoveTileItem(msg, creature->getPosition(), stackpos);
            msg->AddByte(0x6A);

            msg->AddPosition(creature->getPosition());
            msg->AddByte(stackpos);
            AddCreature(msg, creature, false, creature->getID());
        }
        else
            AddTileCreature(msg, creature->getPosition(), stackpos, creature);
    }
}


this is 1.3x
C++:
void ProtocolGame::reloadCreature(const Creature* creature)
{
    if (!canSee(creature))
    {
        return;
    }

    int32_t stackpos = creature->getTile()->getClientIndexOfCreature(player, creature);
    if (stackpos >= 10)
    {
        return;
    }

        NetworkMessage msg;

        std::unordered_set<uint32_t>::iterator it;
        if ( it != knownCreatureSet.end() )
        {
            RemoveTileThing(msg, creature->getPosition(), stackpos);
            msg.addByte(0x6A);

            msg.addPosition(creature->getPosition());
            msg.addByte(stackpos);
            AddCreature(msg, creature, false, creature->getID());
        }
        else
        {
            sendAddCreature(creature, creature->getPosition(), stackpos, false);
        }
}


the code edited by min (1.3) does not have the functionality, could someone give me this support and help me solve this?
I have doubts about sending and receiving bytes, if you can answer some questions about it, I'll be grateful!

how does it work?
msg.addByte(0x6A), msg.addPosition, msg.addByte, msg.addString;

first question
if i send a byte to the client, how can i get that byte that was sent? how does the client see this? since there are several bytes sent, how does he know I want x byte?

second question
how can i get bytes sent from the client and work them on the server?
in advance, I thank everyone who responds!

a leitura de pacotes acontece em protocolgame.cpp, em uma instrução de switch com bytes iniciais dos pacotes
no friend, I don't think you understand, opcodes are bytes too, but they are sent to the client and vice versa.
sorry for my google translator english.
