RE: Lua and C++ (stack)

[Erwin Oegema <blablaechthema@...>]

I don't really use these preprocessor macros (we don't need to use them). The problem still lies on the stack that is changed when calling the function from Lua.
The only thing that Npc::sendGetNumber does is sending a packet to the client with these variables. They are not stored and such.

void Npc::sendGetNumber(int32_t def, int32_t min, int32_t max) {
    PacketCreator packet = npcPacket(NpcDialogs::GetNumber);
    packet.add<int32_t>(def);
    packet.add<int32_t>(min);
    packet.add<int32_t>(max);
    player->getSession()->send(packet);
}
