Hi everyone,

It's finally time to open a topic for the small tutorials, it's better than flooding the board with one sentence topics.

1. Binary name check: Sure, it's possible to do it on client-side, but if we can do it on server-side, theres no reason to do it on client-side.

1. Search for this function in game/input.cpp:

void CInputProcessor::Version(LPCHARACTER ch, const char* c_pData)

2. Replace the entire function with this:

	if (!ch)
	{
		return;
	}

	TPacketCGClientVersion * p = (TPacketCGClientVersion *) c_pData;

	// If the file name is not metin2client.exe and the GM level is not equal with GM_IMPLEMENTOR kick the player
	if (strcmp(p->filename, "metin2client.exe") && ch->GetGMLevel() != GM_IMPLEMENTOR)
	{
		// immediately close the connection with the player
		sys_err("%s[%d] has been disconnected: %s", ch->GetName(), ch->GetPlayerID(),  p->filename);
		ch->GetDesc()->SetPhase(PHASE_CLOSE);
		return;
	}

	sys_log(0, "VERSION: %s %s %s", ch->GetName(), p->timestamp, p->filename);
	ch->GetDesc()->SetClientVersion(p->timestamp);

2. Block the drop hacks: This issue is surely known by everybody, the server gets overloaded when dropping too many items in short time.

1. Open game/char_item.cpp and search for this:

if (pkItemToDrop->AddToGround(GetMapIndex(), pxPos))

2. Add this under that:

// Clear the variable, it looks the player does not dropped any item in the past second.
if (thecore_pulse() > LastDropTime + 25)
	CountDrops = 0;
	
// It looks the player dropped min. 4 items in the past 1 second
if (thecore_pulse() < LastDropTime + 25 && CountDrops >= 4)
{
	// Set it to 0
	CountDrops = 0;
	sys_err("%s[%d] has been disconnected because of drophack using", GetName(), GetPlayerID());
        // Disconnect the player
	GetDesc()->SetPhase(PHASE_CLOSE);
	return false;
}

3. Search for this still in game/char_item.cpp:

LogManager::instance().ItemLog(this, pkItemToDrop, "DROP", szHint);

4. Add this under that:

		LastDropTime = thecore_pulse();
		CountDrops++;

5. Open game/char.h and add these:

		int					LastDropTime;
		int					CountDrops;

6. Open game/char.cpp and search for this:

void CHARACTER::Initialize()

7. Add these to the function:

	CountDrops    = 0;
	LastDropTime  = 0;

Here are some new small Quest functions:

Get the IP address of the player:

	int pc_get_ip(lua_State* L)
	{
		lua_pushstring(L, CQuestManager::instance().GetCurrentCharacterPtr()->GetDesc()->GetHostName());
		return 1;
	}

Get the client version of the player:

	int pc_get_version(lua_State* L)
	{
		lua_pushstring(L, CQuestManager::instance().GetCurrentCharacterPtr()->GetDesc()->GetClientVersion());
		return 1;
	}

Delayed disconnect the player:

	int pc_delayed_dc(lua_State* L)
	{
		if (!lua_isnumber(L, 1))
			return 0;

		int dctime = (int)lua_tonumber(L, 1);

		if (dctime <= 0)
			return 0;

		CQuestManager::instance().GetCurrentCharacterPtr()->GetDesc()->DelayedDisconnect(dctime);
		return 0;
	}

Disconnect the player (with reason):

	int pc_dc(lua_State* L)
	{
		const char * reason = lua_tostring(L, 1);

		CQuestManager::instance().GetCurrentCharacterPtr()->Disconnect(reason);
		return 0;
	}

			{ "get_ip",			pc_get_ip },
			{ "get_version",	pc_get_version },
			{ "delayed_dc",		pc_delayed_dc },
			{ "disconnect",		pc_dc },

I just answered a question here about how to load up the exp_table from a txt file, but maybe it will be useful for someone else too:

Open main.cpp and add this to the top:

#include "fstream"

Search for this still in main.cpp:

PanamaLoad();

Add this under that:

	// START_OF_EXP_TABLE_LOADING
	std::string temp_exp_line;
	std::ifstream exp_table_open("exptable.txt");

	if (!exp_table_open.is_open())
		return 0;

	int exp_table_counter = 0;
	while (!exp_table_open.eof())
	{
		exp_table_open >> temp_exp_line;
		str_to_number(exp_table_common[exp_table_counter], temp_exp_line.c_str());
		exp_table_counter++;
	}
	// END_OF_EXP_TABLE_LOADING

Open constants.cpp and replace this:

const DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1] =
{
   ...
};

With this:

DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1];

Open constants.h and replace this:

extern const DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1];

With this:

extern DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1];

exptable.txt example: http://pastebin.com/KPMGPY38

Adrian1428 · August 7, 2014

Many thanks

How can I change the path to the exp table in locale / xx ?

I know I have to change this line:

std::ifstream exp_table_open("exptable.txt");

I tried something but not work

Sanchez · August 7, 2014

std::ifstream exp_table_open("locale/english/exptable.txt");

Adrian1428 · August 20, 2014

std::ifstream exp_table_open("locale/english/exptable.txt");

This I did in the end but I was referring to something else.

I wanted to detect the locale use only.

	{
		const char * = razón lua_tostring (L, 1);

		. CQuestManager :: ejemplo () GetCurrentCharacterPtr () -> Disconnect (razón);
		return 0;
	}

			{"Get_ip", pc_get_ip},
			{"Get_version", pc_get_version},
			{"Delayed_dc", pc_delayed_dc},
			{"Desconexión", pc_dc},

If I understand correctly. This is a record if some player has lag?

			exp_table_counter++;

Your code is wrong...

Here's an improved version of experience table.

In constants.h search for

extern const DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1];

And change it to

extern DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1];

In constants.cpp search for

const DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1] =
{
	...
}

And change it to

DWORD exp_table_common[PLAYER_EXP_TABLE_MAX + 1] =
{
	...
}

Now search in config.cpp for

#include <sstream>

And add under

#include <fstream>

Still in config.cpp search for

TOKEN("mark_server")

And add above or under it

TOKEN("exp_table")
{
	if (strlen(value_string) > 0)
		LoadExpTable(value_string);

	continue;
}

Still in config.cpp search for

static void FN_log_adminpage()

And add above or under it

void LoadExpTable(char* name)
{
	std::ifstream f(name);

	printf("EXP_TABLE load: %s n", name);
	if (!f.is_open())
	{
		printf("EXP_TABLE load: FILE %s OPEN ERROR", name);
		return;
	}

	int level = 0;
	DWORD exp = 0;
	int line = 0;

	while (!f.eof())
	{
		f>>level;
		f>>exp;
		line++;
		
		if (level <= 0 || exp <= 0)
			printf("EXP_TABLE load !ERROR!: LINE %d LEVEL %d EXP %ld n", line, level, exp);
        else if (level > PLAYER_EXP_TABLE_MAX)
            printf("EXP_TABLE load !ERROR!: LINE %d LEVEL %d > MAX EXP LEVEL %dn", line, level, PLAYER_EXP_TABLE_MAX);
		else
		{
			printf("EXP_TABLE load: LINE %d LEVEL %d EXP %ld n", line, level, exp);
			exp_table_common[level] = exp;
		}
	}

	printf("EXP_TABLE load: done n");
}

So, a short description:

If you want to edit experience table you have to add in CONFIG of each channel

EXP_TABLE: /path/to/file/exp_table.txt

The file can be anywhere, but you must have the rights to read it.

You can edit experience for the levels you want. You don't need to change all levels. Also, the levels can be in any order you want.

That's the structure of the file:

The first column is for levels and the second is for experience. Between them can be space or tab or even new lines (but it must be one after another).

For the file I specified above you should get this in PuTTy or any SSH client you use (at the end of MAP_ALLOW probably):

EXP_TABLE load: /path/to/file/exp_table.txt
EXP_TABLE load: LINE 1 LEVEL 1 EXP 1000
EXP_TABLE load: LINE 2 LEVEL 2 EXP 20000
EXP_TABLE load: LINE 3 LEVEL 89 EXP 10
EXP_TABLE load !ERROR!: LINE 4 LEVEL 5 EXP 0
EXP_TABLE load: LINE 5 LEVEL 7 EXP 30
EXP_TABLE load: done

As you see if you specify 0 exp for a level it just skip it (as i did for level 5, line 4).

Also, if the file is empty or does not exists it will not load it.

Tip: I added lines to be easier for you to find where you did something wrong

EDIT: Add check for level.

Have fun.

Console spam annoys me so I had to make it look like this.

Anyway, thank you for your hard work, guess I wouldn't toy with *.txt tables if I hadn't seen your script.

It's clean, readable and really easy modifiable.

It's not an error, it's more like display problem (in game everything should work).

When your DWORD has same size as int (clearly has) you can go to config.cpp and change

DWORD exp = 0;

to

long int exp =0;

if you need bigger size you can use long long int but then you'll have to replace every %ld with %lld

I like clean code . I cleaned the source a lot xD

Glad to help.

@Cataclismo:

DWORD exp = 0;
to
long int exp =0;
if you need bigger size you can use long long int but then you'll have to replace every %ld with %lld

It's not really recommended to do this.

The experience table is type DWORD (and DON'T change the type if you don't know what you're doing) which is an unsigned long.

Maximum value of DWORD can be 4,294,967,295. If you wrote in experience table a value bigger than 4,294,967,295 then the things will fuck up. Try to adjust experience to fit in this value. Edit the rates of your server to fit in those values too.

my exp_table.txt:

error in putty: (exp negative)

If you can see in he loaded experience table with maximum value of 4,278,420,394 which is much higher than your max. My guess is that you redefined type DWORD or is already defined wrong which would be strange. If you redefined DWORD then restore it. If you didn't then in config.cpp change

DWORD exp = 0;

to

unsigned long exp = 0;

Build game, start server and the most important step: test if the experience is correct by leveling in game!

Don't work... error in putty exp negative (-)

I changed

DWORD exp = 0;

to

unsigned long exp = 0;

but no difference...

Try that

void LoadExpTable(char* name)
{
    std::ifstream f(name);
 
    printf("EXP_TABLE load: %s n", name);
    if (!f.is_open())
    {
        printf("EXP_TABLE load: FILE %s OPEN ERROR", name);
        return;
    }
 
    int level = 0;
    long long int exp = 0;
    int line = 0;
 
    while (!f.eof())
    {
        f>>level;
        f>>exp;
        line++;
         
        if (level <= 0 || exp <= 0)
            printf("EXP_TABLE load !ERROR!: LINE %d LEVEL %d EXP %lld n", line, level, exp);
        else if (level > PLAYER_EXP_TABLE_MAX)
            printf("EXP_TABLE load !ERROR!: LINE %d LEVEL %d > MAX EXP LEVEL %dn", line, level, PLAYER_EXP_TABLE_MAX);
        else
        {
            printf("EXP_TABLE load: LINE %d LEVEL %d EXP %lld n", line, level, exp);
            exp_table_common[level] = exp;
        }
    }
 
    printf("EXP_TABLE load: done n");
}

There shouldn't be any problems unless your EXP table exceed this number 9223372036854775807 which I think won't happen.

//Forgot to mention.. When you get bigger numbers in your EXP table than 4294967295, this line will start to make errors:

exp_table_common[level] = exp;

so be cautious.
