八、随机布雷
/// <summary> /// 随机布地雷 /// </summary> /// <param name="mineNum">地雷数</param> private void SetRndMine(int mineNum) { for (int k = 0; k < mineNum; k++) { int nullnum = 0; for (int j = 0; j < _gameLevel._colGrid; j++) { for (int i = 0; i < _gameLevel._rowGrid; i++) { if (_backData[j, i] == (int)BackState.BLANK) nullnum++; } } if (nullnum < 1) return; int index = rnd.Next(1, nullnum); nullnum = 0; for (int j = 0; j < _gameLevel._colGrid; j++) { for (int i = 0; i < _gameLevel._rowGrid; i++) { if (_backData[j, i] == 0) { nullnum++; if (nullnum != index) continue; _backData[j, i] = (int)BackState.MINE; // 设置为地雷 } } } } }
这个方法是不是很熟悉，我们在2048游戏中用到过，这里就不再多说了。
九、设置地雷旁边的格子标注的地雷数值
原理就是读取地雷位置，然后分别给不是地雷的格子数值+1。
/// <summary> /// 设置地雷周围格子雷数 /// </summary> private void SetCellMineNumber() { for (int y = 0; y < _gameLevel._colGrid; y++) { for (int x = 0; x < _gameLevel._rowGrid; x++) { if (_backData[y, x] == (int)BackState.MINE) // 遇到地雷则周围8格分别+1 { if (x - 1 > -1 && y - 1 > -1 && _backData[y - 1, x - 1] != (int)BackState.MINE) _backData[y - 1, x - 1]++; if (y - 1 > -1 && _backData[y - 1, x] != (int)BackState.MINE) _backData[y - 1, x]++; if (y - 1 > -1 && x + 1 < _gameLevel._rowGrid && _backData[y - 1, x + 1] != (int)BackState.MINE) _backData[y - 1, x + 1]++; if (x - 1 > -1 && _backData[y, x - 1] != (int)BackState.MINE) _backData[y, x - 1]++; if (x + 1 < _gameLevel._rowGrid && _backData[y, x + 1] != (int)BackState.MINE) _backData[y, x + 1]++; if (y + 1 < _gameLevel._colGrid && x - 1 > -1 && _backData[y + 1, x - 1] != (int)BackState.MINE) _backData[y + 1, x - 1]++; if (y + 1 < _gameLevel._colGrid && _backData[y + 1, x] != (int)BackState.MINE) _backData[y + 1, x]++; if (y + 1 < _gameLevel._colGrid && x + 1 < _gameLevel._rowGrid && _backData[y + 1, x + 1] != (int)BackState.MINE) _backData[y + 1, x + 1]++; } } } }
十、设置背景区图片组
循环读取背景区数据，根据数值设置对应的图片源。
private void SetBackCellImage() { BackCanvas.Children.Clear(); for (int y=0; y<_gameLevel._colGrid; y++) { for (int x=0; x<_gameLevel._rowGrid; x++) { _backImage[y, x] = new Image(); if (_backData[y, x] == (int)BackState.BLANK) { _backImage[y, x].Source = ImageHelper.CutImage(_bmpSpace, new Int32Rect(0, 0, _cellSize.Width, _cellSize.Height)); } else if (_backData[y, x] == (int)BackState.MINE) { _backImage[y, x].Source = ImageHelper.CutImage(_bmpMine, new Int32Rect(0, 0, _cellSize.Width, _cellSize.Height)); } else { for (int i = 0; i < 8; i++) { if (_backData[y, x] == (i+1)) { _backImage[y, x].Source = ImageHelper.CutImage( _bmpNum1_8, new Int32Rect(i * _cellSize.Width, 0, _cellSize.Width, _cellSize.Height)); break; } } } _backImage[y, x].SetValue(Canvas.LeftProperty, x * (double)_cellSize.Width); _backImage[y, x].SetValue(Canvas.TopProperty, y * (double)_cellSize.Height); BackCanvas.Children.Add(_backImage[y, x]); } } }
十一、开始游戏准备
根据游戏级别分别调用随机布雷、设置雷边数值方法，同时添加背景图片数组到游戏背景区。
private void ResetGame() { InitialGameState(); InitGameData(_level); textBlockMineNum.Text = _gameLevel._mineNum.ToString(); SetRndMine(_gameLevel._mineNum); SetCellMineNumber(); SetBackCellImage(); }
将该方法添加到开始游戏菜单中，并计时器打开。
private void MenuGameStart_Click(object sender, RoutedEventArgs e) { ResetGame(); _gameState = GameState.START; // 开始计时 _stopWatchGame.Start(); _timerSetTimeText.Start(); }
重复点击开始菜单，看看效果。
十二、调整游戏级别
根据菜单设置的当前级别值设置菜单选择状态。
/// <summary> /// 设置级别菜单状态 /// </summary> /// <param name="level"></param> private void SetMenuLevelState(Level level) { switch (level) { case Level.SIMPLE: MenuLowLevel.IsChecked = true; MenuMiddleLevel.IsChecked = false; MenuHighLevel.IsChecked = false; break; case Level.NORMAL: MenuLowLevel.IsChecked = false; MenuMiddleLevel.IsChecked = true; MenuHighLevel.IsChecked = false; break; case Level.HARD: MenuLowLevel.IsChecked = false; MenuMiddleLevel.IsChecked = false; MenuHighLevel.IsChecked = true; break; } }
/// <summary> /// 初级级别菜单 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void MenuLowLevel_Click(object sender, RoutedEventArgs e) { if (_level == Level.SIMPLE) return; if (MessageBox.Show("将用新难度级别重置游戏，确认要继续吗？", "警告", MessageBoxButton.YesNo, MessageBoxImage.Asterisk) == MessageBoxResult.Yes) { _level = Level.SIMPLE; SetMenuLevelState(_level); ResetGame(); } } /// <summary> /// 中级级别菜单 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void MenuMiddleLevel_Click(object sender, RoutedEventArgs e) { if (_level == Level.NORMAL) return; if (MessageBox.Show("将用新难度级别重置游戏，确认要继续吗？", "警告", MessageBoxButton.YesNo, MessageBoxImage.Asterisk) == MessageBoxResult.Yes) { _level = Level.NORMAL; SetMenuLevelState(_level); ResetGame(); } } /// <summary> /// 高级级别菜单 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void MenuHighLevel_Click(object sender, RoutedEventArgs e) { if (_level == Level.HARD) return; if (MessageBox.Show("将用新难度级别重置游戏，确认要继续吗？", "警告", MessageBoxButton.YesNo, MessageBoxImage.Asterisk) == MessageBoxResult.Yes) { _level = Level.HARD; SetMenuLevelState(_level); ResetGame(); } }
十三、设置前景区图片组
/// <summary> /// 设置前景图片数组 /// </summary> private void SetForeCellImages() { ForeCanvas.Children.Clear(); for (int y = 0; y < _gameLevel._colGrid; y++) { for (int x = 0; x < _gameLevel._rowGrid; x++) { if (_foreData[y, x] > (int)ForeState.NONE) { _foreImage[y, x] = new Image(); _foreImage[y, x].Source = ImageHelper.CutImage(_bmpForeground, new Int32Rect(0, 0, _cellSize.Width, _cellSize.Height)); _foreImage[y, x].SetValue(Canvas.LeftProperty, x * (double)_cellSize.Width); _foreImage[y, x].SetValue(Canvas.TopProperty, y * (double)_cellSize.Height); ForeCanvas.Children.Add(_foreImage[y, x]); } } } }
在ResetGame()方法最后位置加入对该方法的调用。
运行程序，看看效果。
