连连看 代码的实现
背景：宽度46，高度392/7=56
动物：宽度78/2=39 高度1638/42=39
画图：
步骤一：建立与窗口DC兼容的内存DC
hdc=GetDC(hWnd);
mdc=CreateCompatibleDC(hdc);
步骤二：加载位图：
hbmp=(HBITMAP)LoadImage(NULL,"3DFrames.bmp",IMAGE_BITMAP,46,392,LR_LOADFROMFILE);
步骤三：画图
SelectObject(mdc,hbmp);
BitBlt(hdc,0,0,BGWIDTH,BGHEIGHT,mdc,0,BGHEIGHT,SRCCOPY);
禁止缩放窗口：
hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW& ~WS_THICKFRAME,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);
// & ~WS_MAXIMIZEBOX & ~WS_MINIMIZEBOX,//禁止最大化最小化
调整窗口大小：
RECT rcClient,rcWind;
POINT ptDiff;
GetClientRect(hWnd,&rcClient);
GetWindowRect(hWnd,&rcWind);
ptDiff.x=(rcWind.right-rcWind.left)-rcClient.right;
ptDiff.y=(rcWind.bottom-rcWind.top)-rcClient.bottom;
MoveWindow(hWnd,100,100,10*BGWIDTH+ptDiff.x,8*BGHEIGHT+ptDiff.y,TRUE);
画动物：
BitBlt(hdc,0*ANIMALWIDTH+3,0*ANIMALHEIGHT+8,ANIMALWIDTH,ANIMALHEIGHT,mdc,ANIMALWIDTH,ANIMALHEIGHT,SRCAND);
BitBlt(hdc,0*ANIMALWIDTH+3,0*ANIMALHEIGHT+8,ANIMALWIDTH,ANIMALHEIGHT,mdc,0,ANIMALHEIGHT,SRCPAINT);
MyPaint示例：
void MyPaint()
{
SelectObject(mdc,hbmp);
int x,y;
for(y=0;y<8;y=y++)
{
for(x=0;x<10;x++)
{
BitBlt(hdc,x*BGWIDTH,y*BGHEIGHT,BGWIDTH,BGHEIGHT,mdc,0,BGHEIGHT,SRCCOPY);
}
}
SelectObject(mdc,hanimal);
for(y=0;y<8;y=y++)
{
for(x=0;x<10;x++)
{
BitBlt(hdc,x*BGWIDTH+3,y*BGHEIGHT+8,ANIMALWIDTH,ANIMALHEIGHT,mdc,ANIMALWIDTH,ANIMALHEIGHT,SRCAND);
BitBlt(hdc,x*BGWIDTH+3,y*BGHEIGHT+8,ANIMALWIDTH,ANIMALHEIGHT,mdc,0,ANIMALHEIGHT,SRCPAINT);
}
}
}
鼠标:
case WM_LBUTTONDOWN:
newpos.x=LOWORD(lParam)/BGWIDTH;
newpos.y=HIWORD(lParam)/BGHEIGHT;
if(check==FALSE)
{
oldpos=newpos;
}
else
{ if(map[oldpos.y*10+oldpos.x]==map[newpos.y*10+newpos.x]&&IsLink(oldpos.x,oldpos.y,newpos.x,newpos.y))
{
if(oldpos.x!=newpos.x||oldpos.y!=newpos.y)
map[oldpos.y*10+oldpos.x]=map[newpos.y*10+newpos.x]=-1;
MyPaint();
}
}
check=!check;
break;
