Lahap Dupe Protection

[Shatter]

thought this might come handy for the mu coders who are out there, since i left myself and have all kinds of stuff lying around useless guess dont mind releasing some, after all sharing is caring

Structs

struct tagInterfaceState 
{
/*<bitfield this+0x0>*/ /*|0x4|*/ unsigned long use:2;
/*<bitfield this+0x0>*/ /*|0x4|*/ unsigned long state:4;
/*<bitfield this+0x0>*/ /*|0x4|*/ unsigned long type:0xA;
};

THE CODE BELOW GOES TO OBJECTSTRUCT

/*<thisrel this+0xe74>*/ /*|0x4|*/ struct tagInterfaceState m_IfState;

Lahap Protection

case 0xBC:
if(ObjTable[aIndex].m_IfState.use > 0 && ObjTable[aIndex].m_IfState.type != 12)
return false;
break;

this piece of code checks the states, and if someone tries to dupe, gs returns a false and breaks the action. yet simple but effective.

in addition you can implement a logger and/or an individual system, some kind of punishment system for example.

Example 1

case 0xBC:
if(ObjTable[aIndex].m_IfState.use > 0 && ObjTable[aIndex].m_IfState.type != 12)
LogAddFunc(2,"[Anti-Hack][Trade Dupe] [Lahap] (%s)(%s)",gObj->AccountID,gObj->Name);
return false;
break;

Example 2

case 0xBC:
if(ObjTable[aIndex].m_IfState.use > 0 && ObjTable[aIndex].m_IfState.type != 12)
LogAddFunc(2,"[Anti-Hack][Trade Dupe] [Lahap] (%s)(%s)",gObj->AccountID,gObj->Name);
DupeProtection(aIndex);
return false;
break;

-----

void DupeProtection(aIndex)
{
if (DupePunishmentSystem = 0)
{
return;
}
if (PunishmentType = 1)
{
GCServerMsgStringSend("Kiss My Ass Nawb",aIndex,1);
}
if (PunishmentType = 2)
{
GCServerMsgStringSend("Hai, You Just Got BANNED",aIndex,1);
SQL.Execute(UPDATE MuOnline.dbo.MEMB_INFO SET ctl1_code = '1' WHERE memb___id = '%s'",gObj->AccountID);
}
else
{
do nothing
}
}

Definitions

#define LogAddFunc ((void(*) (unsigned char cor,char* Texto,...)) 0x00403CC9) <- For 1.00.18 GS

This is useful only up to .18 gs since it has been fixed by webzen on .66 and later versions.

Thanks shatter

uhm, i think leo or drakelv release it, on coderzfactory forums, i dont know if was there today

Edit: i think was on his S3 EP1 Project, no?
Edit2: the source are differents but the idea is the same

[devisz]

was smth included in his files, not something usefull for others who use other versions
