Thread: Simple drawing text and rect for any d3d9 game

Here is everything you need for drawing text or rect.
d3dhooks.h

class DXGH

{

public:

void DrawFillRect(IDirect3DDevice9* dev, int x, int y, int w, int h,unsigned char r, unsigned char g, unsigned char b);

static HRESULT WINAPI h_EndScene(LPDIRECT3DDEVICE9 pDevice); //End scene

};



int StartD3DHooks(); //call this later for our hooks



typedef HRESULT(WINAPI *EndScene_t)(LPDIRECT3DDEVICE9 pDevice); //For our original

extern DXGH   DXGameHook;

d3dhooks.cpp

DXGH                                           DXGameHook;

//Our end scene hook

HRESULT WINAPI DXGH::h_EndScene(LPDIRECT3DDEVICE9 pDevice)

{  



DXGameHook.DrawFillRect(pDevice,500,100,100,100,90  ,100,255);

   return org_EndScene(pDevice); //Return orig

}



/*

Using D3D Clear To Create  rectangle

*/

void DXGH::DrawFillRect(IDirect3DDevice9* dev, int x, int y, int w, int h,unsigned char r, unsigned char g, unsigned char b)

{

   D3DCOLOR rectColor = D3DCOLOR_XRGB(r,g,b);   //No point in using alpha because clear & alpha dont work!

   D3DRECT BarRect = { x, y, x + w, y + h }; 



   dev->Clear(1,&BarRect,  D3DCLEAR_TARGET | D3DCLEAR_TARGET ,rectColor,0,0);

}



int StartD3DHooks()

{

   DWORD D3DPattern,*vTable, DXBase=NULL;

   DXBase = (DWORD)LoadLibraryA("d3d9.dll");

     

   while(!DXBase);

      {

        D3DPattern = GameHook->FindPattern(DXBase, 0x128000, (PBYTE)"\xC7\x06\x00\x00\x00\x00\x89\x86\x00\x00\x  00\x00\x89\x86", "xx????xx????xx");   //Searching for the D3D Pattern

      }



   if(D3DPattern)

   {

      //if D3D Pattern is found. then do hooks

      memcpy(&vTable,(void *)(D3DTrue+2),4);

      org_EndScene = (EndScene_t)GameHook->DetourFunction((PBYTE)vTable[ENDSCENE],(PBYTE)DXGameHook.h_EndScene,5);

   }

   return 0;

}

And finally dllMain.cpp:

BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpReserved )

{

    switch( fdwReason ) 

    { 

      case DLL_PROCESS_ATTACH:

      {

         DisableThreadLibraryCalls(hinstDLL);

                        // Do the call here

                        StartD3DHooks()

      return true;

      break;

      }

        case DLL_PROCESS_DETACH:

      {

         

            break;

      }

    }

    return TRUE; 

}

The outcome:
