Write a visual studio program in C++ using DirectX. The program has to be a bomb catcher game and it should look like this (with both the bomb and the red hat moving):

* Start with an empty project and have these files: MyDirectX.h , MyDirectX.cpp, MyWindows.cpp, + MyGame.cpp

* gameInitialize, gameRun and gameEnd can be stored in MyGame.cpp

* These are slides that the program should be based on (but these slides are NOT the entire program):

* Thank you in advance for your help.

Bomb Catcher Game Create a Surface Here is how you create a surface: Global variable: LPDIRECT3DSURFACE9 surfaceNULL; LPDIRECT3DSURFACE9 backbuffer = NULL; In Game Init() d3ddev.->CreateoffscreenPlainSurface ( 100, 100, D3DFMT X8R8G8B8 D3DPOOL DEFAULT &surface, NULL) //width of the surface //height of the surface //surface format //memory pool to use //pointer to the surface //reserved (always NULL); d3ddev.->GetBackBuffer( 0, 0, D3DBACKBUFFER TYPE MONO &backbuffer); Load a Bitmap File In order to load a bitmap file into a surface so that it can be presented, we must include and into project. And we must add d3dx9.lib to the project setting (as we did in chapter 5) From now on, all projects will require d3d9.lib and d3dx9.lib in project setting D3DXLoadSurfaceFromFile function supports file formats: Windows Bitmap (standard DirectDraw Surface (DirectX 7) Windows Device Independent Bitmap Joint Photographic Experts Group (JPEG) Portable Network Graphics T ruevision Targa dds dib png Load a image into surface in Game_Init( //load surface from file D3DXLoadSurfaceFromFile( surface, NULL, NULL, "logo.bmp", I/source filename NULL, D3DX DEFAULT, //use default filter //destination surface //destination palette //destination rectangle //source rectangle // for transparency (0 for none) NULL); I/source image info (usually NULL) Display surf Game _Run() //clear the backbuffer (buffer to draw image) to black ce with bitmap in d3ddey->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,0), 1.0f, 0) if (d3ddev->BeginScene() l/start rendering //draw surface to the backbuffer RECT rect- 10, 0, 100,100); d3ddey->StretchRect(surface, NULL, backbuffer, &rect, D3DTEXF_NONE); d3ddev->EndScene); /stop rendering I/display the back buffer on the screen d3ddev->Present(NULL, NULL, NULL, NULL); Display Surfaces In Game_Run() // copy the source surface onto the dest (backbuffer) to show on screen in region of x-0-100 and y-0-100 RECT rect-0, 0, 100, 100) a3ddey-StretchRect(surface, NULL, Rackbuffer, &rect, D3DTEXF_NONE) The second parameter is a pointer to a rect in source surface The fourth parameter is a pointer to a rect in destination surface * Null if surface is same size with the backbuffer .Specify a rectangular area if surface is smaller than hackbuffer D3DTEXF_NONE means no special filter used Release Surfaces In Game_End() Release //free the surface surface->Release () Directinput Interface and Device Directlnput interface is called IDirectlnput8, whiclh creates a uniform interface to all input devices such as keyboard, mouse, joystick, etc. Pointer is LPDIRECTINPUT8 Directlnput device is called LPDIRECTINPUTDEVICE8. //define a DirectInput8 object LPDIRECTINPUT8 dinput; Creating the Directinput Object Call DirectlnputCreate8 to initialize Directlnput.
