vue实现五子棋游戏

Posted in Javascript onMay 28, 2020

本文实例为大家分享了vue实现五子棋游戏的具体代码，供大家参考，具体内容如下

思路

1.vue实现五子棋

空棋盘开局。

画网格：网格有 15 行 15 列，共有 225 个交叉点
黑先、白后，交替下子，每次只能下一子
胜负判定
按照简单的规则，从当前下子点位的方向判断()。如果有一个方向满足连续5个黑子或白子，游戏结束。

2.支持dom和canvas切换

判断浏览器是否支持canvas：

false: 不支持切换dom方式
true: 支持使用canvas

3.实现悔棋功能

4.实现撤销悔棋

例子：

为了简便，我就把所有写在一起了，按理来说是要分文件写的；
