Code to run in windowed mode ( 2008 )

[espanish]

First you will need to put this functions in you Src :

long __stdcall MSetWindowLongA( HWND hWnd, int nIndex, DWORD dwNewLong )
{
	if( ( nIndex == GWL_STYLE ) ){

		char szClassName[12];
		GetClassNameA( hWnd, szClassName, 11 );
		
		if( !strcmp( "RealSpace2", szClassName ) ){
			dwNewLong = 2161049600;
			
			*(PBYTE)( (DWORD)( *(PDWORD)((DWORD)&dwNewLong + 4) ) + 8 ) = 0;				
		}
	}

	return SetWindowLongA( hWnd, nIndex, (long)dwNewLong );
}

void MIATHook( DWORD dwIATAddress, DWORD dwFunction )
{
	DWORD dwOld;

	VirtualProtect( (LPVOID)dwIATAddress, 4, PAGE_EXECUTE_READWRITE, &dwOld );

	*(DWORD*)dwIATAddress = (DWORD)dwFunction;
	VirtualProtect( (LPVOID)dwIATAddress, 4, dwOld, &dwOld );
}

Soo, in you main thread, when the hooks are applied you do this :

if( MessageBoxA( NULL, "Run in windowed mode ?", "You GunZ", MB_YESNO ) == IDYES ){
	MIATHook( (DWORD)0x62245C, (DWORD)MSetWindowLongA );
}

Compile and run, when you start the game will show a MsgBox asking if you want to start in windowed mode.

Usefull, usefull, keep posting some great release like that, they are soo rare these day...

NICE =]
Thanks man, this is very most useful!

can you also include the fps in the upper corner pls that would be awesome who dev map.

can you also include the fps in the upper corner pls that would be awesome who dev map.

That would require either a hook on Gunz' rendering functions or a DirectX hook.

Gunz d3d device pointer for 07 = 0x68BC2C

Very usefull

Whats the point, get fraps, run it same time as GunZ running obviously, then it will show ur fps in game in the corners... like over 1000 or some ridiculous FPS lol xD

There's also another way to do windowed mode, requires hooking this function (in 08, it's in 07 too in the same spot)

0x00497C60

This is actually "void SetModeParams()". 0x00686D18 is set to 1 no matter what. If it is set to 0, GunZ is restarted in windowed mode on each device reset. You'll need to hook the function and set this stuff, which is easy:

LODWORD(dword_686D10) = *(_DWORD *)(GetVideo() + 8);
  LODWORD(dword_686D14) = *(_DWORD *)(GetVideo() + 12);
  result = GetVideo();
  dword_686D1C = (*(_DWORD *)(result + 16) != 32) + 22;

which roughly translates to,

nWidth = ZGetConfiguration()->nWidth;
nHeight = ZGetConfiguration()->nHeight;
ZGetConfiguration()->nColorBits == 32 ? 
		PixelFormat = 22 : PixelFormat = 23;

Using this method you could probably change the configuration options to support the windowed mode byte, which is also in GetVideo(), being the first 4 bytes of the struct.

That would require either a hook on Gunz' rendering functions or a DirectX hook.

Gunz d3d device pointer for 07 = 0x68BC2C

Re-add me on MSN, I accidentally declined your request about 5 days ago. You should know who I am :p

[Mr_Troy]

You can also just change this BYTE to 0 : 0x4954A6 (07) at Gunz startup.
