What is DirectX?
An Application Programming Interface(API) that provides low level access to multimedia hardware in a device independent manner
Hardware Abstraction Layer (HAL)
Hardware Emulation Layer (HEL)
What do you need to develop a DirectX application?
DirectX Software Developer’s Kit (SDK) http://www.microsoft.com/directx/
Win32 compiler
Language?
A little creativity!
What I am using to develop “Die, Rock, Die.”
Microsoft DirectX SDK v. 5.2
Microsoft Visual C++ 5.0 Professional Edition
Windows 98
Corel Draw Suite 7.0
Sound Forge XP 4.0
Microsoft Force-Feedback Pro Digital Joystick
LPDIRECTDRAW lpdd = NULL; // DD object extern HWND hWnd; // The window handle LPDIRECTDRAWSURFACE lpddsprimary = NULL; // DD primary surface LPDIRECTDRAWSURFACE lpddsback = NULL; // DD back surface DDSURFACEDESC ddsd; // DD surface description
struct
if (DirectDrawCreate(NULL,&lpdd,NULL) != DD_OK) // Create the DirectDraw return(0); // Object
if (lpdd->SetCooperativeLevel(hWnd, // Set cooperation level | DDSCL_FULLSCREEN | DDSCL_EXCLUSIVE | DDSCL_ALLOWREBOOT)!=DD_OK) return(0);
if (lpdd->SetDisplayMode(width,height,bpp)!=DD_OK) // Set the display mode return(0);
Direct Draw Initialization
ddsd.dwSize = sizeof(ddsd); // Set the dwSize field
ddsd.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE | DDSCAPS_FLIP | DDSCAPS_COMPLEX; // Specify the DD
// surface capabilities ddsd.dwBackBufferCount = 1; // How many backbuffers?
lpdd->CreateSurface(&ddsd,&lpddsprimary,NULL); // Create the primary surface
ddscaps.dwCaps = DDSCAPS_BACKBUFFER; // Looking at backbuffer
lpddsprimary->GetAttachedSurface(&ddscaps,&lpddsback); // Query for the backbuffer
while(lpddsprimary->Flip(NULL, DDFLIP_WAIT) != DD_OK); // Flip the surfaces
Direct Draw Initialization (cont’d.)
