Basic tut on using C++ for GunZ

**gpadmin** · 16-12-09

Hello. How change server port 7777 to 4545 and how change same port on client side? Thank you.

Make a separate topic, don't post it here.

Code:

  return( char* ) ( ZGetGameInterface( ) + 0x3A6 /*Or 0x3A8*/ );
}

To clear your last input, I believe all you have to do is:

Code:

void Clear( )
{
  (* (char* ) ( ZGetGameInterface( ) + 0x3A6 /*Or 0x3A8*/ ) ) = '\n';
}

That's chat input, but I had problems having ZChatOutput display a message after input. Previously I used:

Code:

 memcmp( ChatInput( ), "/hi", 3 ) == 0 ) { /*do stuffs */ }

Here's another method to receive and use an argument in a input.

Code:

if( memicmp( ChatInput( ), "/silentchat ", 11 ) == 0 )
{
    char playerName;
    char msg;
    sscanf( ChatInput( ), "/silentchat %s %s", &playerName, &msg );
    ZPostWhisper( "From: Me", playername, msg );
    ClearInput( );
}

(Code not tested)
Edit: Forgot the ClearInput

If you forget to add the "ClearInput", you will not be able to input another command.

Edit2: I plan on updating this tutorial tonight or tomorrow night on finding an using pointers, adding/removing functions in "theduel.exe", and creating custom commands in C++ and ASM.

Thanks for this.

Ok this is the script:

Code:

#include <windows.h>

typedef void(__cdecl *ZChatType) (const char*, int, int, DWORD);
ZChatType ZChatOutput = (ZChatType)0x0042A230;

void Chat2()
{


	for(;;Sleep(20)) //Infinite Loop
  {
char* ChatInput( )
{
  return( char* ) ( ZGetGameInterface( ) + 0x3A6 /*Or 0x3A8*/ );
}

if( memcmp( ChatInput( ), "/hi", 3 ) == 0 ) { 
	ZChatOutput("Hello!", 2, 0, 0xFFFFFF);
	Sleep(250);
 }
}
}

extern "C"
{
    __declspec(dllexport) BOOL __stdcall DllMain(HINSTANCE hInst,DWORD reason,LPVOID lpv)
    {
        DisableThreadLibraryCalls(hInst);
        if (reason == DLL_PROCESS_ATTACH)
        {
			MessageBox(NULL, L"I love Music!", L"Niels:", MB_OK);
            CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&Chat2, NULL, 0, NULL);  //Remember our void?  "MyThread" ??
		}
        return true;
	}
}

And I get this error:

Code:

1>c:\documents and settings\administrator\mijn documenten\visual studio 2008\projects\chat2\chat2\main.cpp(13) : error C2601: 'ChatInput' : local function definitions are illegal

1>Chat2 - 2 error(s), 0 warning(s)

It´s probaly because of the ZGetGameInterface.
How to make it load the interface of in-game(Not lobby or room)

I posted it here because I think it get faster a respond to it.

Check line 11.

Also your code needs indentation for readability.

And, you need to define the address of ZGetGameInterface.

I corrected the indentation for you:

Spoiler:

**00niels00** · 28-12-09

Code:

#include <windows.h>
#include "ZFuncs.h"


char* ChatInput( )
{
	return( char* ) ( ZGetGameInterface( ) + 0x3A6 /*Or 0x3A8*/ );
}

		void MyThread()
{
	for(;;Sleep(20)) 
  {
if( memcmp( ChatInput( ), "/dood", 4 ) == 0 )
        { 
			ZCharacter::SetHP(0);
			ZCharacter::SetAP(0);
	Sleep(250);
        }
}
}

extern "C"
{
    __declspec(dllexport) BOOL __stdcall DllMain(HINSTANCE hInst,DWORD reason,LPVOID lpv)
    {
        DisableThreadLibraryCalls(hInst);
        if (reason == DLL_PROCESS_ATTACH)
        {
            MessageBox(NULL, L"Injected", L"HI", MB_OK);
            CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&MyThread, NULL, 0, NULL);  //Remember our void?  "MyThread" ??
		}
        return true;
	}
}

Ok thats the code I've now. I compiled it and injected it. But gunz just crashes how do I fix that.

I use the Zfuncs from heroin.dll.

Try that.

Thnx for the tut.

**00niels00** · 29-12-09

Ok it still chrashes. Probaly because it tries to execute. And can't find it.

So I tought like this:

PHP Code:


#include <windows.h>
#include "ZFuncs.h"

char* ChatInput( )
{
    return( char* ) ( ZGetGameInterface( ) + 0x3A8 );
}

void Clear( )
{
  (* (char* ) ( ZGetGameInterface( ) + 0x3A8 ) ) = '\n';
}

void MyThread( )
{
    for( ;;Sleep( 20 ) ) 
    {
        if (ZGetGameInterface!=0x0) {
        if( memcmp( ChatInput( ), "/dood", 4 ) == 0 )
        { 
        ZCharacter::SetHP(0);
        ZCharacter::SetAP(0);
            Clear( ); //You have to clear you're last input, or you can't input another command.
        }
        }
    }
}

extern "C"
{
    __declspec( dllexport ) BOOL __stdcall DllMain( HINSTANCE hInst, DWORD dwReason, LPVOID lpv )
    {
        DisableThreadLibraryCalls( hInst );
        if ( dwReason == DLL_PROCESS_ATTACH )
        {
            Beep( 500, 500 );
            CreateThread( NULL, 0, ( LPTHREAD_START_ROUTINE )&MyThread, NULL, 0, NULL );
        }
            return true;
    }
}

But it still doesn't work.

Maybe is the handling of the ZGetGameInterface wrong

PHP Code:


DWORD ZGetGameInterface()
{
    DWORD ReturnVal;
    if (ZGetGameInterfaceAddress!=0x0)
    {
        __asm
        {
            MOV EAX, ZGetGameInterfaceAddress
            CALL EAX
            MOV ReturnVal, EAX
        }
    }else{
        return 0x0;
    }
return ReturnVal;
}

        }
    }else{
        return 0x0;
    }
return ReturnVal;
}

That is the structure for pChar(), if I am correct.

I have provided the definition for ZGetGameInterface().

Code:

typedef DWORD(__cdecl *ZGetGameInterfaceType)();
ZGetGameInterfaceType ZGetGameInterface = (ZGetGameInterfaceType)0x004ABCF0;

Enjoy.

No, that is ZGetGameInterface. Snail's did it straight through inline ASM. Probably the sig. searcher isn't finding the address for ZGetGameInteface.

Microssoft visual c++ is the same of Hex Work Shop?

**bounty-hunter** · 11-01-10

Trying to translate Zchatoutput to Delphi :
C++:

Code:

typedef void(__cdecl *ZChatOutputType) (const char*, int, int, DWORD);
ZChatOutputType ZChatOutput = (ZChatOutputType)0x0042BAE0; //FAKE Address *points to jjang*

my Delphi attempt:

Code:

 const
  ADDRESS = $0042BAE0; // some fakeaddress

 type
  TZChatoutput = procedure (char : Pchar; int1 : integer; int2 :integer; MyWord:Dword);

var
GunZChat:TZChatoutput = TZChatOutput(ADDRESS);

begin
GunZChat('bounty-hunta :O',2,1,$FFFFFF);
end;

going to need the real zchatoutput to test this ..

You wish. (Also, don't bump topic older than 3 weeks, I've noticed that happening: You might get infracted.)
