继拼图游戏后的第二个巩固小游戏——简单双人五子棋对战游戏

前言

因为我的拼图游戏是跟着视频慢慢做的,所以我想自己独立完成一个小游戏的制作。五子棋是一个可以验证我这段时间的学习成果以及巩固知识的小项目,所以今天我打算做一个简单双人五子棋对战游戏。

难点

1,JPanel的使用:

因为我以前没用过哈哈哈,所以在开始前我先学习了一下JPanel的使用,那我为什么学习JPanel呢?在查阅资料的时候,发现JFrame其实是主要容器,画图在JPanel上会分工更加明确,规划更加合理,效率更高,减少卡顿。)

2,判断是否结束游戏:

游戏的胜利即相同颜色五个棋子连在一起,那我应该怎么去判断呢?首先你要知道现在下的是哪个棋子,也就是判断正在下完这一手是否能够触发胜利条件。如刚刚所说,五个棋子连在一起(水平方向,竖直方向,左上右下,右下左上)就算成功,那么我们只要对这四种情况进行相连数量判断就可以了,如果撞到边界或者碰到其他颜色棋子就break,若棋子颜色相同就count++,一旦有任何一个方向count==5,那则可结束游戏。

实现效果

可以看见这个棋盘是由:主棋盘,棋子(黑白),计数器,下棋方提醒,重新游戏按钮以及结束弹窗组成。

源码

废话不多说,因为是第二个项目所用知识点与上一个拼图小游戏相似我就不多描述了,直接上代码!

·Test

test没啥好说的就是测试类,我来测试代码运行的,嘻嘻

写在最后

因为是自己写的代码,测试了几十次和用ai测试了没显示太大问题,但可能存在隐性问题。

如果发现我代码存在的问题请在评论区告诉我,十分感谢!
