Function - Same IP Detection

[WeedHex 661]

Spoiler

May be worth

 

if (!pkKiller || !pkVictim)
    return;

if (IsSameIp(pkKiller, pkVictim))
    return; //Same ip detected

Thank you for your Release could be useful for pvp server, do you have a idea how to turn off all names example given Character names and more EXCEPT the item names of items on ground ? 

[Metin2 Dev 12235]

I'm trying to use static as less as possible. What is the reason this really needs to be static?

Also, what about couples that play together on one IP?

Idea is good, not perfect solution, but at least something.

I put it only for share fastly here.

Btw the function works perfectly deteting the ip in string way.

Vegas quest functions

Server/quest_functions:

pc.get_ip
npc.get_ip

Src/game/questlua_pc.cpp
 

int pc_get_ip(lua_State* L)
    {
        LPCHARACTER ch = CQuestManager::instance().GetCurrentCharacterPtr();
        if(!ch) return 0;
        lua_pushstring(L, ch->GetDesc()->GetHostName());
        return 1;
    }

    { "get_ip",                pc_get_ip                            },

Src/game/questlua_npc.cpp
 

int npc_get_ip(lua_State* L)
    {
        LPCHARACTER npc = CQuestManager::instance().GetCurrentNPCCharacterPtr();
        if (npc && npc->IsPC())
            lua_pushstring(L, npc->GetDesc()->GetHostName());
        else
            lua_pushstring(L, "");
        return 1;
    }

    { "get_ip",                        npc_get_ip                        },

 

#include "desc.h"

[VegaS™ 13082]

Good idea, but you should return false if GetDesc is nullptr, not true.

static const bool __FN_check_ip_ptr(const LPCHARACTER pkChr, const LPCHARACTER pkTargetChr)
{
	if (!pkChr || !pkTargetChr)
		return false;
	
	const LPDESC pkDesc = pkChr->GetDesc();
	const LPDESC pkTargetDesc = pkTargetChr->GetDesc();
	if (!pkDesc || !pkTargetDesc)
		return false;
	
	const std::string & stIPAddress1 = pkDesc->GetHostName();
	const std::string & stIPAddress2 = pkTargetDesc->GetHostName();
	return (!stIPAddress1.compare(stIPAddress2));
}

static const bool __FN_check_ip_str(const std::string & stIPAddress1, const std::string & stIPAddress2)
{
	return (!stIPAddress1.compare(stIPAddress2));
}

// const bool bIsSameIP = __FN_check_ip_ptr(ch, tch);
// const bool bIsSameIP = __FN_check_ip_str(row[0], row[1]);

It's a little bit useless if two guys play metin2 from same network connection, as @Chyu ^^ said.
We can use HWID (Hardware Identification) for this detection, much better.

Thank you VegaS!

Added somewhere (even .h)

inline bool ch_compare_ip(LPCHARACTER ch1, LPCHARACTER ch2)
{
	if (!ch1 || !ch2 || !ch1->GetDesc() || !ch2->GetDesc())
		return false;
	const std::string ip1 = ch1->GetDesc()->GetHostName();
	const std::string ip2 = ch2->GetDesc()->GetHostName();
	return (ip1.compare(ip2) == 0);
}

or if added in char.h inside CHARACTER:

inline bool CHARACTER::CompareIP(LPCHARACTER ch2)
{
	if (!ch2 || !this->GetDesc() || !ch2->GetDesc())
		return false;
	const std::string ip1 = this->GetDesc()->GetHostName();
	const std::string ip2 = ch2->GetDesc()->GetHostName();
	return (ip1.compare(ip2) == 0);
}

I'm using this, you can use number or string with same function:

 

 

bool Check_IP (auto first, auto second) 
{ 
	return first == second;	
}
