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
1 2 3 4 5 6 7 8 |
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:
constant为自己定义 MouseListener为鼠标监听 ActionListener为事件监听函数
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

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。
