（3）游戏随机选择方块模块

在游戏中，每一个下落的方块都是随机的，包括颜色，形状。 实现此功能相关代码如下： void CGameDlg::Shape() { }

int line=18; int rr=4; CDC *pDC=GetDC(); ASSERT(pDC!=NULL);

CPen pen;

pen.CreatePen (PS_SOLID,1,RGB(0,0,0)); CBrush brush1,brush2,brush3;

brush1.CreateSolidBrush(RGB(60,60,60)); brush3.CreateSolidBrush(RGB(0,170,0)); brush2.CreateSolidBrush(BackColor);

pDC->SelectObject (pen); pDC->SelectObject (brush1);

pDC->Rectangle(X-line,Y-line,X+M*r+line,Y+N*r+line);

int b=line*2/3,c=b-rr; pDC->SelectObject (brush3);

pDC->Rectangle(X-b,Y-b,X+M*r+b,Y+N*r+b); pDC->SelectObject (brush1);

pDC->Rectangle(X-c,Y-c,X+M*r+c,Y+N*r+c);

pDC->SelectObject (brush2);

pDC->Rectangle(X-2,Y-2,X+M*r+2,Y+N*r+2); DeleteObject(pen);DeleteObject(brush1); DeleteObject(brush2);DeleteObject(brush3);

ReleaseDC(pDC);

//外部框架

void CGameDlg::one(int Type, int i, int j) //某元格颜色 位置 { if(Runing==0) { OnDestroy(); return;

}

CDC *pDC=GetDC(); ASSERT(pDC!=NULL);

COLORREF color,L_color=RGB(0,0,0); switch(Type) {

case 0: color=L_color=BackColor;break; case 1: color=RGB(131,129,222); break; case 2: color=RGB(250,90,130); break; case 3: color=RGB(40,220,250); break; case 4: color=RGB(40,120,50); break; case 5: color=RGB(0,250,0); break; case 6: color=RGB(131,19,222); break; case 7: color=RGB(120,190,30); break; case 8: color=RGB(140,20,150); break; case 9: color=RGB(40,120,150); break; case 10: color=RGB(23,62,180); break; case 11: color=RGB(131,129,22); break; case 12: color=RGB(20,190,130); break; case 13: color=RGB(40,234,220); break; case 14: color=RGB(140,70,150); break; case 15: color=RGB(30,150,40); break; case 16: color=RGB(78,203,30); break; case 17: color=RGB(120,100,30); break; case 18: color=RGB(240,70,20); break; case 19: color=RGB(40,180,90); break;

pDC->Rectangle(X+i*r,Y+j*r,X+(i+1)*r,Y+(j+1)*r); DeleteObject(pen); DeleteObject(brush); ReleaseDC(pDC);

}

（4）游戏预览功能模块

此模块用来为游戏爱好者提供下一个方块的信息， 实现此功能相关代码如下： void CGameDlg::PreView()

//预先显示组

{

if(Runing==0)

}

void CGameDlg::OnButton1() { }

14

if(object2.y+b3<0||object2.y+b5<0||object2.y+b7<0||object2.y<0)

CDC *pDC = GetDC(); ASSERT(pDC != NULL); OnDraw(pDC); ReleaseDC(pDC);
