void CMineWnd::LayMines(UINT row, UINT col) { srand( (unsigned)time( NULL ) ); UINT i, j; for(UINT index = 0; index < m_uMineNum;) { i = rand() % m_uYNum; j = rand() % m_uXNum; if (i == row && j == col) continue; if(m_pMines[i][j].uAttrib != ATTRIB_MINE) { m_pMines[i][j].uAttrib = ATTRIB_MINE; index++; } } }此处的srand( (unsigned)time( NULL ) );是为了每次产生的随机数都不相同。展开空白窗体周围的区域:
void CMineWnd::ExpandMines(UINT row, UINT col) { UINT i, j; UINT minRow = (row == 0) ? 0 : row - 1; UINT maxRow = row + 2; UINT minCol = (col == 0) ? 0 : col - 1; UINT maxCol = col + 2; UINT around = GetAroundNum(row, col); m_pMines[row][col].uState = 15 - around; m_pMines[row][col].uOldState = 15 - around; // redraw special MINEWND DrawSpecialMine(row, col); if (around == 0) { for (i = minRow; i < maxRow; i++) { for (j = minCol; j < maxCol; j++) { if (!(i == row && j == col) && m_pMines[i][j].uState == STATE_NORMAL && m_pMines[i][j].uAttrib != ATTRIB_MINE) { if (!IsInMineArea(i, j)) continue; ExpandMines(i, j); } } } } }此处为一个递归函数,查找需要展开的小窗体周围的8个小窗体,若再次查找到空白,再进行查找,直到把能展开的全部展开。其他的几个主要的函数代码量比较大,各位可以到附带的实例代码中去看,就不在这里祥述了 。
