JAVA程序设计(12.3)---- 监听器初级应用:五子棋
1.制作五子棋游戏软件
因为老师已经基本做完了,重做的时候快了很多……但是还是感觉思维很混乱…… 哪边先哪边后,哪个方法在哪边好之类的问题 太纠结了……
先是窗口 内部类:鼠标适配器 窗口的构造器 绘图
package com.lovo.homework2; import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.image.BufferedImage; import javax.swing.JFrame; import javax.swing.JOptionPane; /** * 类 : 我的五子棋窗口 * * @author Abe */ public class MyFrameRenju extends JFrame { private MyboardRenju board = new MyboardRenju(); private boolean isBlack = true; private Image offImage = new BufferedImage(800, 800, BufferedImage.TYPE_INT_RGB);// 双缓冲 private boolean isGameOver = false; /** * 内部类:鼠标适配器 * * @author Abe */ public class MyMouseAdapter extends MouseAdapter { @Override public void mousePressed(MouseEvent e) { // 重写点击鼠标的方法 if (!isGameOver) { int x = e.getX(); int y = e.getY(); if (x > 25 && x < 775 && y > 25 && y < 775) { int i = (x - 25) / 50; int j = (y - 25) / 50; if (board.move(i, j, isBlack)) { repaint(); if (board.win(i, j, isBlack)) { JOptionPane.showMessageDialog(null, isBlack ? "黑方胜!" : "白方胜"); isGameOver = true; } isBlack = !isBlack; } } } } } /** * 构造器 */ public MyFrameRenju() { this.setTitle("五子棋"); this.setSize(800, 800); this.setResizable(false); this.setDefaultCloseOperation(EXIT_ON_CLOSE); this.setLocationRelativeTo(null); this.setLayout(null); this.getContentPane().setBackground(new Color(180, 125, 12)); MyMouseAdapter l = new MyMouseAdapter(); this.addMouseListener(l); } /** * 重写方法画出所有 newG均为双缓冲 去掉闪屏需要 */ @Override public void paint(Graphics g) { Graphics newG = offImage.getGraphics(); super.paint(newG); board.draw(newG); g.drawImage(offImage, 0, 0, 800, 800, null); } public static void main(String[] args) { new MyFrameRenju().setVisible(true); } }
然后是位置面板,绘制棋子,走棋,判断胜负
package com.lovo.homework2; import java.awt.BasicStroke; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Shape; import java.awt.Stroke; import javax.xml.bind.annotation.adapters.CollapsedStringAdapter; /** * 类 : 五子棋棋盘 * * @author Abe * */ public class MyboardRenju { private int[][] p = new int[15][15]; // 给每个交点赋值 public void draw(Graphics g) { g.setColor(Color.BLACK); Graphics2D g2d = (Graphics2D) g; // 强转g为2D型 赋值给g2d g2d.setStroke(new BasicStroke(5)); g.drawRect(50, 50, 700, 700); g2d.setStroke(new BasicStroke(1)); g.fillOval(392, 392, 16, 16); // 画天元 星 g.fillOval(195, 195, 10, 10); g.fillOval(195, 595, 10, 10); g.fillOval(595, 195, 10, 10); g.fillOval(595, 595, 10, 10); for (int i = 0; i < 750; i += 50) { // 画横纵坐标线 g.drawLine(50, 100 + i, 750, 100 + i); g.drawLine(100 + i, 50, 100 + i, 750); } for (int i = 0; i < p.length; i++) { // 画出棋盘上的棋子 for (int j = 0; j < p.length; j++) { if (p[i][j] != 0) { g.setColor(p[i][j] == 1 ? Color.black : Color.WHITE); g.fillOval(25 + i * 50, 25 + j * 50, 50, 50); } } } } /** * 走棋 */ public boolean move(int i, int j, boolean isBlack) { if (p[i][j] == 0) { p[i][j] = isBlack ? 1 : 2; return true; } return false; } /** * 方法:判断胜负 */ public boolean win(int i, int j, boolean isBlack) { int currentColor = isBlack ? 1 : 2; if (countH(i, j, currentColor) >= 5 || countV(i, j, currentColor) >= 5 || countX1(i, j, currentColor) >= 5 || countX2(i, j, currentColor) >= 5) { return true; } return false; } private int countH(int i, int j, int currentColor) { int counter = 1; int tempi = i; while (--tempi >= 0 && p[tempi][j] == currentColor) { counter++; } tempi = i; while (++tempi <= p.length && p[tempi][j] == currentColor) { counter++; } return counter; } private int countV(int i, int j, int currentColor) { int counter = 1; int tempj = j; while (--tempj >= 0 && p[i][tempj] == currentColor) { counter++; } tempj = j; while (++tempj <= p.length && p[i][tempj] == currentColor) { counter++; } return counter; } private int countX1(int i, int j, int currentColor) { int counter = 1; int tempi = i; int tempj = j; while (--tempj >= 0 && --tempi >= 0 && p[tempi][tempj] == currentColor) { counter++; } tempi = i; tempj = j; while (++tempj <= p.length && ++tempi <= p.length && p[tempi][tempj] == currentColor) { counter++; } return counter; } private int countX2(int i, int j, int currentColor) { int counter = 1; int tempi = i; int tempj = j; while (--tempj >= 0 && ++tempi >= 0 && p[tempi][tempj] == currentColor) { counter++; } tempi = i; tempj = j; while (++tempj <= p.length && --tempi <= p.length && p[tempi][tempj] == currentColor) { counter++; } return counter; } }
