I can't get my font size to change??

Hello, I've been going through the NeHE Lessons and I am now on Lesson 13. I can get it to run fine but when I try to change the size of the font It will not get smaller or bigger... I've looked at the documentation on msdn and searched google on the CreateFont function and i'm getting no luck... I'm looking for a pointer as to why my text won't change size.. Here is the code I am using... GLvoid BuildFont(bool outline) { HFONT font; HFONT oldFont; // int PointSize = 0; // int nHeight = -MulDiv(PointSize, GetDeviceCaps(_pGame->GetHDC(), // LOGPIXELSY), 72); if (outline == true) { // Comic Sans MS MessageBox(NULL, "Outline", "Outline", MB_OK); base = glGenLists(256); font = CreateFont(-12,0,0,0,FW_BOLD,false,false,false,ANSI_CHARSET, OUT_TT_PRECIS,CLIP_DEFAULT_PRECIS,ANTIALIASED_QUALITY, FF_DONTCARE | DEFAULT_PITCH,"Comic Sans MS"); } else { MessageBox(NULL, "Bitmap", "Bitmap", MB_OK); base = glGenLists(96); font = CreateFont(-24,0,0,0,FW_BOLD,false,false,false,ANSI_CHARSET, OUT_TT_PRECIS,CLIP_DEFAULT_PRECIS,ANTIALIASED_QUALITY, FF_DONTCARE | DEFAULT_PITCH,"Courier New"); } oldFont = (HFONT)SelectObject(_pGame->GetHDC(),font); if (outline == true) { MessageBox(NULL, "Outline", "Outline", MB_OK); wglUseFontOutlines(_pGame->GetHDC(),0,255,base,0.0f,0.2f, WGL_FONT_POLYGONS,gmf); } else { MessageBox(NULL, "Bitmap", "Bitmap", MB_OK); wglUseFontBitmaps(_pGame->GetHDC(),32,96,base); } SelectObject(_pGame->GetHDC(),oldFont); DeleteObject(font); } GLvoid glPrint(bool outline, const char *fmt, ...) { float lenght = 0; char text[256]; va_list ap; if (fmt == NULL) { return; } va_start(ap,fmt); vsprintf(text,fmt,ap); va_end(ap); for (unsigned int loop = 0; loop < (strlen(text)); loop++) { lenght += gmf[text[loop]].gmfCellIncX; } glTranslatef(-lenght/2,0.0f,0.0f); glPushAttrib(GL_LIST_BIT); if (outline) { glListBase(base); } else { glListBase(base - 32); } glCallLists(strlen(text), GL_UNSIGNED_BYTE, text); glPopAttrib(); } int DrawGLScene(GLvoid) { // Heres where we do ALL the drawing // Clear the screen and the depth buffer glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); DrawMap(); glEnable(GL_COLOR_MATERIAL); glEnable(GL_LIGHTING); glTranslatef(0.0f,0.0f,-1.5f); glColor3f(1.0f,1.0f,0.0f); glPrint(true, "Lotas - %3.2f", rot/50); glDisable(GL_COLOR_MATERIAL); glDisable(GL_LIGHTING); glColor3f(1.0f,1.0f,1.0f); rot += 0.1f; return true; // Everything went OK } int initGL(GLvoid) { // All setup for openGL goes here // Start Of User Initialization if (!LoadBitmap("Data/wall.bmp", texture[0], GL_LINEAR, GL_LINEAR_MIPMAP_NEAREST, 1)) // Load The Bitmap return FALSE; if (!LoadBitmap("Data/floor.bmp", texture[1], GL_LINEAR, GL_LINEAR, 0)) // Load The Bitmap return FALSE; if (!LoadBitmap("Data/ceiling.bmp", texture[2], GL_LINEAR, GL_LINEAR_MIPMAP_NEAREST, 1)) // Load The Bitmap return FALSE; if (!LoadBitmap("Data/lobManga5.bmp", texture[3], GL_LINEAR, GL_LINEAR_MIPMAP_NEAREST, 1)) // Load The Bitmap return FALSE; if (!LoadBitmap("Data/door1.bmp", texture[4], GL_LINEAR, GL_LINEAR_MIPMAP_NEAREST, 1)) // Load The Bitmap return FALSE; if (!LoadBitmap("Data/Glass.bmp", texture[5], GL_LINEAR, GL_LINEAR_MIPMAP_NEAREST, 1)) // Load The Bitmap return FALSE; // glColor4f(1.0f, 1.0f, 1.0f, 0.5f); glEnable(GL_TEXTURE_2D); // Enable Texture mapping glBlendFunc(GL_SRC_ALPHA, GL_ONE); glClearColor(0.0f,0.0f,0.0f,0.0f); // Black Background glClearDepth(1.0f); // Depth Buffer setup glDepthFunc(GL_LEQUAL); // The type of Depth Test to do glEnable(GL_DEPTH_TEST); // Enable Depth Testing glShadeModel(GL_SMOOTH); // Enable smooth shading // Really nice perspective calculations glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST); glEnable(GL_LIGHT0); BuildFont(true); SetupWorld(); return true; // Initialization went OK } I'm trying to add some text to a map I created. I want to move the text with the camera but first I need to get it to be much smaller... If you need more code just let me know :) Thanks in advance for the help :)

Ahh yes 3D fonts , well i geuss i'll just have to load certain fonts and there sizes into memory at startup, and use those.

Thank you for your time and information.

We can forgive a man for making a useful thing as long as he does not admire it. The only excuse for making a useless thing is that one admires it intensely.-- ? --

font = CreateFont(-24,0,0,0,FW_BOLD,false,false,false,ANSI_CHARSET,
OUT_TT_PRECIS,CLIP_DEFAULT_PRECIS,ANTIALIASED_QUALITY,
FF_DONTCARE | DEFAULT_PITCH,"Courier New");
change the
-24
to the SIZE you want
i like the -14
it looks good
