java五子棋小游戏实现代码

作者:為什麼不问问神奇海螺呢

这篇文章主要为大家详细介绍了java五子棋实现代码,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

前言

之前学完java基础课程,试着简单做了一下java的一个五子棋小游戏,记录下来。

界面

由于直接用的java库中的一些基本控件写的一个GUI,并没有做过多优化,感觉比较丑
下面是界面展示:

黑子先行,但是我这边简化规则,并没有考虑黑子先行的一些禁手。

下面直接贴代码

接口类

我把五子棋界面的一些常量都定义在了这个接口类中,包括棋盘的起始坐标,棋盘线的间距和棋子半径

public interface constant {

    int[][] chessLocation = new int[15][15];
    static final int x = 50;   //左上角位置
    static final int y = 50;
    static final int LN = 15;  //棋盘一些常量
    static final int R = 45;
}

实现类

接口

这个类中继承了 constant、MouseListener、ActionListener三个接口

其中:

函数

show()绘制窗口基本框架
paint()绘制棋盘网格线和棋子
IsWin()判断输赢的基本逻辑
mouseClicked()获取鼠标位置,判断棋子落点等
actionPerformed()判断鼠标点击哪个按钮(开始游戏or认输or悔棋)执行相应操作

import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

public class game_logic extends JPanel implements constant, MouseListener, ActionListener {
    int chess_x = 0, chess_y = 0;
    int X = 0, Y = 0;
    boolean IsBlack = true; //判断黑白
    boolean flag = false;  //是否已经开始游戏
 //生成三个响应按钮
    JFrame frame = new JFrame();
    JButton start = new JButton("开始游戏");
    JButton regret = new JButton("悔棋");
    JButton Lost = new JButton("认输");
 
    public void ShowUI() {
        frame.setSize(740, 800);
        frame.setTitle("五子棋");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//点击关闭结束程序
        frame.setLocationRelativeTo(null);//窗口居中
        frame.setVisible(true);//窗体可视化
        frame.setResizable(false);//窗体大小不可调整
        frame.add(this);

        this.setBackground(Color.LIGHT_GRAY);//设置背景颜色
        this.addMouseListener(this);//窗体中添加鼠标监听器

        start.setSize(50, 80);//设置按钮大小
        start.addActionListener(this);//按钮添加事件监听器
        Lost.setSize(50, 80);
        Lost.addActionListener(this);
        regret.setSize(50, 80);
        regret.addActionListener(this);

        this.add(start);//添加按钮到棋盘上
        this.add(Lost);
        this.add(regret);

    }

            IsBlack = !IsBlack;
            repaint();
        }
    }
}

其中比较有趣的是五子棋判赢方式,假设棋盘大小15*15,则我只需要判断正中间的13*13d的格子,向两边扩展,判断是否五子连珠。

具体说明代码里都有注释,不多赘述。

主函数类

public class Main_game {
    public static void main(String[] args) {
        game_logic start=new game_logic();
        start.ShowUI();
    }
}

总结

实现了五子棋小游戏的基本功能,但是略感粗糙,细节不足。对于基本控件调用一学就会,做一个小的游戏demo这是对流程控制和操作逻辑的训练很有效的一种方式。之前看了别人的代码觉得简单,但是自己写的时候往往逻辑流程难以连续,思维混乱,有些过程只有自己写了才知道其中的坑。

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
