扫雷代码

1.按钮监听

package com.saolei.contorl;

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JOptionPane;

import com.saolei.model.ComputeModel;
import com.saolei.view.BoomFrame;
import com.saolei.view.StartFrame;

public class BoomLook implements ActionListener {//监听类
 private BoomFrame win;// 定义BoomFrame窗口
 private int row, col;// 定义行、列
 private StartFrame win0;// 定义StartFrame窗口
 private long time, htime, s;// 定义时间的存放位置

 public BoomLook(BoomFrame win, int row, int col) {
  super();
  this.win = win;               //构造方法重载
  this.row = row;
  this.col = col;
 }

 @Override
 public void actionPerformed(ActionEvent e) {
  // TODO 自动生成的方法存根
  setType(row, col);

 }

 // 给雷界面设置监听动作
 public void setType(int row, int col) {
  JButton but = win.getBut()[row][col];
  but.setBorder(finalBoom.Bor2);// 把按钮的边线设置为单线
  but.setBackground(Color.orange);// 把按钮的颜色设置为橙色
  htime = System.currentTimeMillis();// 获取每点击一次按钮的时间
  s = (htime - win.getTime()) / 1000;// 算出点击按钮时的游戏时间

  this.win.getNum2().setText(
    ComputeModel.formatNum(Integer.parseInt(s + "")));// 将时间文本设置为三位数显示
  if (ComputeModel.isboom(row, col, win.getBoompost(), win.getBwidth())) {// 判断点击的按钮是否为地雷
   but.setIcon(finalBoom.boom[0]);// 添加图片
   JOptionPane.showMessageDialog(win, "壮志未酬身先死!!!!", "你猜！！",
     JOptionPane.ERROR_MESSAGE);// 弹出信息窗口“你输了”
   win.setVisible(false);// 关闭弹出窗口时，游戏界面一起隐藏
   win0 = new StartFrame();// 重新打开选择难度界面
  } else {
   // JButton[][] but0 = new JButton[win.getBwidth()][win.getBhight()];
   int sum = 0;
   // 计算剩余没有点击按钮的个数
   for (int i = 0; i < win.getBwidth(); i++) {
    for (int j = 0; j < win.getBhight(); j++) {
     JButton but0 = win.getBut()[i][j];
     // System.out.println(win.getBut()[i][j].getBorder());
     // System.out.println((finalBoom.Bor0));
     if (win.getBut()[i][j].getBorder() == finalBoom.Bor0) {
      sum++;
      // System.out.println(sum);
     }
    }
   }
   // 如果剩余按钮的个数与地雷数相同，则游戏胜利；并弹出信息“你赢了”
   if (sum == win.getBoomnum()) {
    JOptionPane.showMessageDialog(win, "恭喜！！你赢了！！", "你猜！！",
      JOptionPane.PLAIN_MESSAGE);
    win.setVisible(false);
    win0 = new StartFrame();
   }

   int count = ComputeModel.getRoundBoomCount(row, col,
     win.getBoompost(), win.getBwidth(), win.getBhight());
   //如果按钮不是地雷，给出其周边八个按钮的雷数
   if (count > 0) {
    but.setText(count + "");

   } else {
    //如果没有雷，进行递归
    int[][] round = ComputeModel.getRoundBox(row, col);
    for (int i = 0; i < round.length; i++) {
     // 检测格子是否合法
     if (ComputeModel.ispost(round[i][0], round[i][1],
       win.getBwidth(), win.getBhight())) {
      // 检测格子是否已经调用，否则继续递归
      if (win.getBut()[round[i][0]][round[i][1]].getBorder() != finalBoom.Bor2) {
       setType(round[i][0], round[i][1]);
      }
     }
    }

   }
  }
 }
}
