Thread: ID3DXFont not drawing

I have used ID3DXFont before but it was before I used this new code base and now I can't get it to work. All the font creation and drawing calls are working and I just can't see what's wrong.

WinMain

Code:

/* Globals */
const UINT g_iWidth = 1024;
const UINT g_iHeight = 768;
HWND g_hWnd;

const char szClassName[ ] = "DirectX App";

IDirect3D9 *g_pD3D;
IDirect3DDevice9 *g_pDevice;
d3d App;
ID3DXFont *font = 0;
char *font_name = "Times New Roman";


int WINAPI WinMain (HINSTANCE hThisInstance,HINSTANCE hPrevInstance,LPSTR lpszArgument,int nFunsterStil){
  MSG msg;
  ::ZeroMemory(&msg,sizeof(MSG));

  if(!InitWindow(g_iWidth,g_iHeight,hThisInstance,nFunsterStil)){
    ::MessageBox(0, "InitWindow() - FAILED", 0, 0);
  }

  if(!App.InitD3D(g_hWnd, g_iWidth, g_iHeight, true, D3DDEVTYPE_HAL, &g_pD3D, &g_pDevice)){
    ::MessageBox(0, "InitD3D() - FAILED", 0, 0);
    return 0;
  }

  Setup();

  App.EnterMsgLoop(Display,msg);

  Cleanup();
  return msg.wParam;
}

Setup

Code:

bool Setup(){
  D3DXCreateFont(g_pDevice,
                 22,
                 0,
                 FW_NORMAL,
                 1,
                 false,
                 DEFAULT_CHARSET,
                 OUT_DEFAULT_PRECIS,
                 ANTIALIASED_QUALITY,
                 DEFAULT_PITCH|FF_DONTCARE,
                 "Arial",
                 &font);

  return true;
}

Display

Code:

bool Display(float timeDelta){
  RECT rect;
  SetRect(&rect,0,0,640,480);

  g_pDevice->Clear(0,0,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,0x77777777,1.0f,0);
  g_pDevice->BeginScene();
    font->DrawText(NULL,"Hello World!",-1,&rect,DT_LEFT|DT_NOCLIP,0x00000000);
  g_pDevice->EndScene();

  g_pDevice->Present(0,0,0,0);
  return true;
}

You probably don't ned to see this one but I'll show it just incase

d3d::InitD3D

Code:

bool d3d::InitD3D(HWND hWnd, int width, int height, bool windowed,
                  D3DDEVTYPE deviceType, IDirect3D9 **D3D, IDirect3DDevice9 **device){


  *D3D = Direct3DCreate9( D3D_SDK_VERSION );
  if(!(*D3D)){
    return false;
  }
  D3DPRESENT_PARAMETERS d3dpp;
  ZeroMemory(&d3dpp,sizeof(d3dpp));

  d3dpp.BackBufferWidth = width;
  d3dpp.BackBufferHeight = height;
  d3dpp.BackBufferFormat = D3DFMT_A8R8G8B8;
  d3dpp.BackBufferCount = 1;
  d3dpp.MultiSampleType = D3DMULTISAMPLE_NONE;
  d3dpp.MultiSampleQuality = 0;
  d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
  d3dpp.hDeviceWindow = hWnd;
  d3dpp.Windowed = windowed; 
  d3dpp.EnableAutoDepthStencil = true;
  d3dpp.AutoDepthStencilFormat = D3DFMT_D24S8;
  d3dpp.Flags = 0;
  d3dpp.FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT;
  d3dpp.PresentationInterval = D3DPRESENT_INTERVAL_IMMEDIATE;

  if(FAILED((*D3D)->CreateDevice(D3DADAPTER_DEFAULT, deviceType, hWnd,
                              D3DCREATE_HARDWARE_VERTEXPROCESSING,&d3dpp, device))){
    (*D3D)->Release();
    D3D = NULL;
    return false;
  }


  return true;
}

Your color param for DrawText is wrong, or at least not what you meant. You have 0x00000000, what you probably wanted was black text, fully opaque. That is to say, 0xFF000000. Be sure to mind the alpha component. Also, it's handy to use one of the many helpful color creation macros already available to you from DirectX (i.e. D3DCOLOR_XRGB ).
