教你用Java做出一个五子棋小游戏
让我先来从注册到登陆再到玩一局演示一下
🎯一、用户注册类
类名就叫做 Register.java
这里我们用到了JFrame，窗口。JFrame 是一个可以独立显示的组件，一个窗口通常包含有标题、图标、操作按钮(关闭、最小化、最大化)，还可以为窗口添加菜单栏、工具栏等。一个进程中可以创建多个窗口，并可在适当时候进行显示、隐藏 或 销毁。
控制用户注册的类主要代码
这里只放主要代码，不然太长不利于阅读
public class Register extends JFrame{
/*
* 用户注册
*/
final JLabel welcomeRegisterLabel = new JLabel("欢迎注册开心五子棋！");
final JLabel userLabel = new JLabel("用户名：");
final JTextField userjt = new JTextField(14);
final JLabel passwordLabel = new JLabel("密码：");
final JPasswordField passwordjp = new JPasswordField(14);
final JLabel confirmPasswordLabel = new JLabel("确认密码：");
final JPasswordField confirmPasswordjp = new JPasswordField(14);
final JLabel yanzhengmajl = new JLabel("验证码：");
final JTextField yanzhengmajt = new JTextField("请输入验证码", 7);
final JLabel yanzhengmaUpdate = new JLabel("看不清？换一张");
final JButton register = new JButton(" 注 册 ");
final JLabel back = new JLabel("返回");
final JLabel tipUserAlreadyRegistered = new JLabel("该账号已经注册！");
final JLabel tipUserNameEmpty = new JLabel("用户名为空！");
final JLabel tipUserNameLessThan5Char = new JLabel("账号少于5个字符！");
final JLabel tipPasswordEmpty = new JLabel("密码不能为空!");
final JLabel tipPasswordLessThan6Char = new JLabel("密码少于6个字符！");
final JLabel tipPasswordInconfirmity = new JLabel("两次密码不一致!");
final JLabel tipConfirmPasswordqualified = new JLabel("重复密码正确！");
final JLabel tipyanzhengmaerror = new JLabel("验证码输入不正确!");
final DrawYZM drawyzm = new DrawYZM();
final Random r = new Random();
static String userName = new String();
static String password = new String();
final FileOperation read = new FileOperation();
String repeatPassword = new String();
String yanzhengma = new String();
String yzm = new String();
int flagUserName = 0;
int flagPassword = 0;
int flagConfirmedPassword = 0;
int flagyanzhengma = 0;
char[] YZM = new char[62];{
for(int i = 0; i < 26; i++) {
YZM[i] = (char) ('A' + i);
}
for(int i = 26; i< 52; i++) {
YZM[i] = (char) ('a' + i - 26);
}
for(char i = 52; i < 62; i++) {
YZM[i] = (char) (i - 4);
}
}
SpringLayout springLayout = new SpringLayout();//使用弹簧布局管理器
}
注册时需要的验证码类
class DrawYZM extends JPanel{
/*
*验证码类
*/
public void paint(Graphics g) {
setBounds(269, 269, 100, 60);
int R = r.nextInt(255);
int G = r.nextInt(255);
int B = r.nextInt(255);
super.paintComponent(g);
Graphics2D g2 = (Graphics2D)g;
int n = 0;
yzm = "";
for(int i = 0; i < 4; i++) {
n = r.nextInt(62);
yzm += YZM[n];
int flag = r.nextInt(2);
Color color = new Color(r.nextInt(200) + 20, r.nextInt(200) + 20, r.nextInt(200) + 20);
g2.setColor(color);
Graphics2D g2d = (Graphics2D)g;
AffineTransform trans = new AffineTransform();//将文字旋转指定角度
if(flag == 0) {
trans.rotate(- r.nextInt(45) * 3.14 / 180, 275 + i * 25, 307);
}else {
trans.rotate(r.nextInt(45) * 3.14 / 180, 275 + i * 25, 307);
}
g2d.setTransform(trans);
g2.setFont(new Font("微软雅黑", 1, 24));
g2.drawString(YZM[n] + "", 277 + i * 22, 307);
}
}
}
🍺二、文件操作类
类名就叫做 FileOperation.java
首先我们需要创建excel文件
包括了编号，用户名，密码，分数，等级，胜利场数，总场数，是否记住密码，是否自动登录，以及注册时间
public void creatExcel(String path) {
String data[] = { "Num","userName", "password", "points", "class",
"winNum", "totalNum", "RememberPassword", "AutoLogin", "date"};
try {
File file = new File(path);
WritableWorkbook book = Workbook.createWorkbook(file);
WritableSheet sheet = book.createSheet("用户信息", 0);
for(int i = 0; i < data.length; i++) {//将信息写入xls文件中
Label label = new Label(i, 0, data[i]);
sheet.addCell(label);
}
book.write();
book.close();
} catch (Exception e) {
System.out.println(e);
}
}
下面的方法用于判断账号是否存在
public boolean readData(String path, String userName) {
File file = new File(path);
if(!file.exists()) {//如果文件不存在
creatExcel("user.xls");//创建文件
}
Workbook workbook = null;
Sheet sheet = null;
Cell cell = null;
boolean flag = false;
try {
workbook = Workbook.getWorkbook(file);
sheet = workbook.getSheet(0);
for(int i = 0; i < sheet.getRows(); i ++) {
cell = sheet.getCell(1, i);
String content = cell.getContents();//获取内容
if(content.equals(userName)) {
flag = true;
break;
}
}
workbook.close();
}catch(Exception e) {
e.printStackTrace();
}
return flag;
}
将用户将信息写入文件中
public void writeData(String path, String userName, String keyword, String data) {
File file = new File(path);//创建文件对象
if(!file.exists()) {//如果文件不存在
creatExcel("user.xls");//创建文件
}
Workbook workbook = null;
WritableWorkbook wtbook = null;
WritableSheet wtsheet = null;
WritableCell wtcell = null;
int flagx = 0;
int flagy = 0;
try {
workbook = Workbook.getWorkbook(file);
wtbook = Workbook.createWorkbook(file, workbook);
wtsheet = wtbook.getSheet(0);//获取第一张表格
for(int i = 0; i < wtsheet.getColumns(); i++) {//查找列
wtcell = wtsheet.getWritableCell(i, 0);
if(wtcell.getType() == CellType.LABEL) {
String cell = ((Label)wtcell).getContents();
if(cell.equals(keyword)) {//定位到关键词的那一行
flagx = i;
break;
}
}
}
if(keyword.equals("userName")) {//如果写入用户名
flagy = wtsheet.getRows();
}else {//写入其他
for(int i = 0; i < wtsheet.getRows(); i++) {//查找行
wtcell = wtsheet.getWritableCell(1, i);
String cell = ((Label)wtcell).getContents();
if(cell.equals(userName)) {
flagy = i;
break;
}
}
}
Label label = new Label(flagx, flagy, data);
wtsheet.addCell(label);
wtsheet.addCell(new Label(0, flagy, String.valueOf((wtsheet.getRows() - 1))));
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
wtbook.write();
} catch (IOException e) {
e.printStackTrace();
}
try {
wtbook.close();
} catch (WriteException | IOException e) {
e.printStackTrace();
}
workbook.close();
}
}
返回对应用户的对应信息
public String backData(String path, String userName, String keyword) {
File file = new File(path);
if(!file.exists()) {//如果文件不存在
creatExcel("user.xls");//创建文件
}
Workbook workbook = null;
Sheet sheet = null;
Cell cell = null;
int flagx = 0;
int flagy = 0;
try {
workbook = Workbook.getWorkbook(file);
sheet = workbook.getSheet(0);
for(int i = 0; i < sheet.getColumns(); i++) {//找到用户名所在行
cell = sheet.getCell(i, 0);
String s = cell.getContents();
if(s.equals(keyword)) {
flagx = i;
break;
}
}
for(int i = 0; i < sheet.getRows(); i++) {
cell = sheet.getCell(1, i);
String s = cell.getContents();
if(s.equals(userName)) {
flagy = i;
break;
}
}
workbook.close();
}catch(Exception e) {
e.printStackTrace();
}
try {
cell = Workbook.getWorkbook(file).getSheet(0).getCell(flagx, flagy);
}catch(Exception e) {
e.printStackTrace();
}
String s = cell.getContents();
return s;
}
✨三、棋盘页面类
棋盘页面类名 Chessboard.java
为棋色选择添加事件监听器
whiteChessLabel.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if(chessboardEmpty == 0) {//只有棋盘为空的时候才能选择棋子颜色
whiteChessjr.setSelected(true);
}
}
});
blackChessLabel.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if(chessboardEmpty == 0) {//只有棋盘为空的时候才能选择棋子颜色
blackChessjr.setSelected(true);
}
}
});
为新局按钮添加事件监听器
newRound.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
for(int i = 0; i < map.length; i++) {//将map数组置0
for(int j = 0; j < map[i].length; j++) {
map[i][j] = 0;
mapflag[i][j] = 0;
}
}
for(int j = 0; j < 225; j++) {//将悔棋标记数组置为0
imapflag[j] = 0;
jmapflag[j] = 0;
}
flag = 0;//行列标记数组下表置0
winFLAG = 0;//输赢标记置0
playerColor = -1;//玩家棋色标记置-1
computerColor = -1;//电脑棋色标记为-1
chessboardEmpty = 0;//棋盘标记为空
player = 1;//玩家先下棋
computer = 0;//电脑后下
newchessX = 0;//新棋子标记置0
newchessY = 0;
depth = 0;
repaint();
}
});
为悔棋添加事件监听器
back.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if(flag - 1 >= 0) {//棋盘上面有棋子的时候, 点击一次棋盘上面少两颗棋子，一颗是自己的，另一颗是电脑的
for(int i = flag - 1; i > flag - 3; i--) {
map[imapflag[i]][jmapflag[i]] = 0;
mapflag[imapflag[i]][jmapflag[i]] = 0;
imapflag[i] = 0;//将坐标存放在悔棋标记数组中
jmapflag[i] = 0;
}
flag = flag - 2;//表示每次悔棋棋盘上双方均少一颗子
winFLAG = 0;
if(flag - 1 >= 0) {
newchessX = imapflag[flag - 1];
newchessY = jmapflag[flag - 1];
}
if(flag == 0) {//表示棋盘为空
chessboardEmpty = 0;//棋盘为空
playerColor = -1;//玩家和电脑棋子颜色置0
computerColor = -1;
depth = 0;
}
repaint();
}else {
;
}
}
});
返回按钮添加事件监听器
returnback.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
dispose();
new Main();
}
});
退出按钮事件监听器
exit.addActionListener(new ActionListener() {//点击退出按钮退出程序
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
鼠标进入棋盘区域内,用于显示提示方框，表示点击之后可以在哪个区域内下棋
addMouseMotionListener(new MouseMotionListener() {
public void mouseMoved(MouseEvent e) {
// TODO 自动生成的方法存根
x = e.getX();
y = e.getY();
if(x >= 247 && x <= 951 && y >=77 && y <= 781) {//如果鼠标点击的点在棋盘内或者边上一点
double m = (x - 270.0)/47.0;//判断点击位置最靠近的哪个交叉点
double n = (y - 100.0)/47.0;
int p = (x - 270)/47;
int q = (y - 100)/47;
int i, j;
if(m - p >= 0.5 || m - p <= -0.5) {
i = p + 1;
}else {
i = p;
}
if(n - q >= 0.5 || n - q <= -0.5) {
j = q + 1;
}else {
j = q;
}
if(i >=0 && i <= 15 && j >= 0 && j <= 15) {//识别到的区域为棋盘之内
if(mapflag[i][j] == 0 && winFLAG == 0 && player == 1) {//表示这个地方没有棋子,并且还没有赢
promptBoxFlag[i][j] = 1;
repaint();
}
}
}
}
public void mouseDragged(MouseEvent e) {}
});
电脑下棋函数
private void tuntoComputer() {//电脑下棋
// TODO 自动生成的方法存根
if(depth >= 7) {
depth = 6;
}
position = Algorithm.evalute(map, depth, computerColor);//调用估值函数
map[position[0]][position[1]] = computerColor;
imapflag[flag] = position[0];//将坐标存放在悔棋标记数组中
jmapflag[flag] = position[1];
newchessX = position[0];//新棋子标记记录坐标
newchessY = position[1];
int a = Math.max(Math.abs(position[0] - 7), Math.abs(position[1] - 7));//计算该点到中心的最大的距离
depth = Math.max(depth, a);//不断更新depth的值
flag ++;
chessboardEmpty = 1;//棋盘标记为有棋子
player = 1;//玩家下棋标志置0
computer = 0;//电脑下棋标志为1
judgeFlag = 1;
repaint();
}
绘制棋盘
for(int i = 0; i < 15; i++) {//横线
g2.drawLine(261, i * 47 + 63, 919, i * 47 + 63);
}
for(int j = 0; j < 15; j++) {//竖线
g2.drawLine(j * 47 + 261, 64, j * 47 + 261, 721);
}
绘制棋子
for(int i = 0; i < map.length; i++) {
for(int j = 0; j < map[i].length; j++) {
//白棋
if(map[i][j] == 1) {
g2.drawImage(white, i * 47 + 241, j * 47 + 43, 40, 40, this);
mapflag[i][j] = 1;//标记位置表示这个地方已经有棋子
}
//黑棋
if(map[i][j] == 2) {
g2.drawImage(black, i * 47 + 241, j * 47 + 43, 40, 40, this);
mapflag[i][j] = 1;
}
}
}
判断棋子是否连成五个
if(judgeFlag == 1) {
judge();
judgeFlag = 0;
}
绘制新棋子红点标记
if(chessboardEmpty != 0) {
g2.setColor(Color.red);
g2.fillOval(newchessX * 47 + 254, newchessY * 47 + 55, 15, 15);
}
绘制鼠标移动方框
for(int i = 0; i < 15; i++) {
for(int j = 0; j < 15; j++) {
if(promptBoxFlag[i][j] == 1) {
g2.setColor(Color.RED);
g2.setStroke(new BasicStroke(2.5f));//设置线条大小
g2.drawLine(238 + i * 47, 40 + j * 47, 248 + i * 47, 40 + j * 47);//上左横线
g2.drawLine(275 + i * 47, 40 + j * 47, 285 + i * 47, 40 + j * 47);//上右横线
g2.drawLine(238 + i * 47, 40 + j * 47, 238 + i * 47, 50 + j * 47);//左上竖线
g2.drawLine(285 + i * 47, 40 + j * 47, 285 + i * 47, 50 + j * 47);//右上竖线
g2.drawLine(238 + i * 47, 77 + j * 47, 238 + i * 47, 87 + j * 47);//左下竖线
g2.drawLine(285 + i * 47, 77 + j * 47, 285 + i * 47, 87 + j * 47);//右下竖线
g2.drawLine(238 + i * 47, 87 + j * 47, 248 + i * 47, 87 + j * 47);//下左横线
g2.drawLine(275 + i * 47, 87 + j * 47, 285 + i * 47, 87 + j * 47);//下右横线
promptBoxFlag[i][j] = 0;
}
}
}
for(int i = 0; i < 5; i++) {//右上角星星
g2.drawImage(happy, 711 + i * 47, 20, 40, 40, null);
}
解决第一次不能显示输赢标志的问题
g2.drawImage(win, 0, 0, 1, 1, null);
g2.drawImage(lose, 0, 0, 1, 1, null);
if(winFLAG == 0 && player == 0) {//表示还未分出胜负并且玩家下了，调用电脑下棋
tuntoComputer();
}
设置下拉框和单选按钮在棋盘不为空的是否不能进行选择
设置棋子颜色单选框可用状态
if(chessboardEmpty == 1) {//棋盘不为空
difficulityClass.setEnabled(false);//设置下拉框不可用
if(whiteChessjr.isSelected()) {//白棋子单选框被选中
blackChessjr.setEnabled(false);
whiteChessjr.setEnabled(true);
}else {//黑棋子单选框被选中
blackChessjr.setEnabled(true);
whiteChessjr.setEnabled(false);
}
}else {//棋盘为空
blackChessjr.setEnabled(true);//释放两个单选框
whiteChessjr.setEnabled(true);
difficulityClass.setEnabled(true);//释放下拉框
}
重绘积分，等级，胜率
classNum = (int)((int)(pointsNum /100 * 0.4 + gamewinNum * 0.4 + gameNum * 0.2) * 0.8);
sunNum = (int) (classNum / 100);
moonNum = (int)(classNum - sunNum * 100) / 50;
starNum = (int)(classNum - sunNum * 100 - moonNum * 50) / 10;
for(t = 0; t < sunNum; t++) {//绘画太阳
g2.drawImage(sun, 75 + t * 30, 538, 30, 30, null);
}
for(t = sunNum ; t < moonNum + sunNum; t++) {//绘画月亮
g2.drawImage(moon, 75 + t * 30, 540, 25, 25, null);

估值算法,返回一个数组，用于记录坐标
public static int[] evalute(int map[][], int depth, int computerColor) {
int maxscore = 0;
Random r = new Random();
int pos[][] = new int[10][2];{

score[i][j] = 0;
}
}
}
int position[] = new int[]{0, 0};//初始化位置坐标数组
for(int i = 6 - depth; i <= 8 + depth && i <= 14; i++) {//搜索横坐标
for(int j = 6 - depth; j <= 8 + depth && j <= 14; j++) {//搜索纵坐标
if(map[i][j] == 0) {//表示该点在棋盘上面为空
score[i][j] = countScore(map, i, j, computerColor);

}
}
}
}
