C++ [c++][1.5] Function only applicable to OTC

[kaincer]

How can I make an if function so that it can only be seen in OTC(if I don't have player or creature as argument)?
networkmessage.cpp
in this example void NetworkMessage::addItem(const Item* item)
I don't have the creature or player argument

my goal is that

void NetworkMessage::addItem(const Item* item)
{
const ItemType& it = Item::items[item->getID()];
    //if Cliente otc {
                           addString(item->getShader()); // ONLY can applicable to OTC. why? Oldclient crash
    //}

only apply in OTC

                           addString(item->getShader());

------------------------------------------------------------- Me fails------------------------------------------
Fail Number 1 : Creature is undefined

void NetworkMessage::addItem(const Item* item)
{
const ItemType& it = Item::items[item->getID()];
const Player* player = creature->getPlayer();

    if (player->getOperatingSystem() >= CLIENTOS_OTCLIENT_LINUX) {
        addString(item->getShader());
    }

Fail Number 2 : does not print anything

void NetworkMessage::addItem(const Item* item)
{
   const ItemType& it = Item::items[item->getID()];
   SpectatorVec spectators;
    g_game.map.getSpectators(spectators, getPosition(), false, true, 1, 1, 1, 1);
    for (Creature* spectator : spectators) {
        std::cout << "Client is: " << spectator->getPlayer()->getOperatingSystem() << std::endl;
        if (spectator->getPlayer()->getOperatingSystem() >= CLIENTOS_OTCLIENT_LINUX) {
            addString(item->getShader());
        }
    }

Fail Number 3 : does not print anything

void NetworkMessage::addItem(const Item* item)
{
const ItemType& it = Item::items[item->getID()];
OperatingSystem_t operatingSystem = static_cast<OperatingSystem_t>(get<uint16_t>());
std::cout << "Client is: " <<operatingSystem << std::endl;
       if (operatingSystem >= CLIENTOS_OTCLIENT_LINUX) {

               addString(item->getShader());

      }

Fail Number 4

 #include "player.h"
void NetworkMessage::addItem(const Item* item)
{
const ItemType& it = Item::items[item->getID()];
if (getOperatingSystem >= CLIENTOS_OTCLIENT_LINUX) {
               addString(item->getShader());
}

You are checking otclient linux for a reason? I hope you are not under windows

I don't know if it's sarcasm

You are checking otclient linux for a reason? I hope you are not under windows

but
>=
that integrates

CLIENTOS_OTCLIENT_LINUX = 10,
    CLIENTOS_OTCLIENT_WINDOWS = 11,
    CLIENTOS_OTCLIENT_MAC = 12,

Lol i did read it wrong nvm

Wait, but is this a new function you are developing or does addItem already exists? How should the engine know "where" to add the item if the only param is item
