Changing Grant name

[thaidu0ngpr0]

Hello

Can someone help me how grant name changing Through Filter
i want to send this packet via the guild master's

I tried many ways, but the filter still only sends by char guild member

PHP Code:

 public void ChangeGrant()
        {

            Packet name = new Packet(0x7256); //C->S
            name.WriteUInt32(12591); // id char Guild member 
            name.WriteAscii("AnhE101"); // grant name
            m_RemoteSecurity.Send(name);
            Send(false);
        }

Do you mean this?

PHP Code:

void CGObjPC::UpdateGrantName(uint32_t player, char *grantname)

If you're not gonna give him a proper answer, then you better not answer.

In topic, there you go: (GameServer code)

push charid; //charid as dword
mov ebx, strptr; //vc80's std::string ptr
mov esi, pcptr; //CGObjPC ptr
call 0x005C7560; //returns short as result code

This is the main function, but it checks if you're the master of the guild, so you don't need that, you need to get deeper.

push stringptr; //vc80's std::string ptr
push 0x25; //just a constant value, its actually update type since the function we're calling now is guild update
push pcptr; //CGObjPC ptr
mov ecx, charid; //charid as dword
xor edx, edx; //edx is a ptr to something, but u set it null so u're fine
call 0x005C80A0; //guild update

This one is guild update function, doesn't do any checks to get your grant name change rejected. So that should be what we need.

You can turn this little assemblies into an actual member function, like:

void CGObjPC::SetGrantName(std::string* grantname)
{
	if (m_instance)
	{
		unsigned int charid = m_instance->CharID;

		__asm
		{
			push grantname;
			push 0x25;
			push this;

			mov ecx, charid;
			xor edx, edx;
			
			mov eax, 0x005C80A0;
			call eax;
		}
	}
}

Or you can just disable the master member class check here:

005CFF9A | 3848 3C                   | cmp byte ptr ds:[eax+3C],cl                      |
005CFF9D | 0F94C1                    | sete cl                                          |
005CFFA0 | 8BC1                      | mov eax,ecx                                      |

And then just use original packets (but that will allow anyone to change the grant name of anyone in his guild to anything he wants)

You can turn this little assemblies into an actual member function, like:

void CGObjPC::SetGrantName(string05* grantname)
{
	if (m_instance)
	{
		unsigned int charid = m_instance->CharID;

		__asm
		{
			push grantname;
			push 0x25;

You have to stop pretending to be smart. Because you got caught in my trap

Looks like you've decided to turn to blablabla talk, after feeling embarrassed.

I won't reply anymore, since there's no point of doing so.
