因为之前用c#的winform中的gdi+,java图形包做过五子棋,所以做这个逻辑思路也就驾轻就熟,然而最近想温故html5的canvas绘图功能(公司一般不用这些),所以做了个五子棋,当然没参考之前的客户端代码,只用使用之前计算输赢判断算法和电脑AI(网络借取)的算法,当然现在html5做的五子棋百度一下非常多,但是自己实现一边总归是好事情,好了废话不多说了进入正题。^_^
目前界面功能:
主界面包含
1:人人、人机对战选项 2:棋子外观选择 3:棋盘背景选择 4:棋盘线条颜色选择
游戏界面包含
1:玩家名称 2:玩家棋子 3:当前由谁下棋背景定位 4:玩家比分 5:功能菜单区域(重新开始和无限悔棋) 6:棋盘区域 7.胜利后连环棋子连接 8.最后下棋位置闪烁显示 9.光标定位
游戏结束界面
1:胜利背景图 2:胜利玩家姓名 3:继续下一把按钮
可增加功能
1.返回主界面 2.保存棋局和相关数据 3.读取棋局和相关数据 4.交换角色 5.网络对战(2台机器)6.双方思考总时间记录
http://sandbox.runjs.cn/show/pl3fyuy4 (注意:没有加棋子图片下载提示,如果使用仿真棋子,出现下棋为空,请等待棋子图片下载完毕)
整体设计
下棋流程:玩家or电脑AI下棋 ---> 绘制棋子 ---> 设定棋子二维坐标值 ----> logic(逻辑判断) ----> (玩家)一方五子连环 ---> 获胜界面
↑ |
| ↓
<--------------------------------------------------------------------------------------------没有五子
悔棋流程(人人对战):一方玩家悔棋 ----> 弹出下棋记录堆栈并设定为它是最后一枚棋 ---> 清除最后一枚棋子图像 ---> 清除棋子二维坐标值---> 重新定位显示最后下棋位置并闪烁
悔棋流程(人机对战):玩方悔棋 ----> 弹出下棋记录堆栈2次,设定上一次电脑为最后一枚棋 ---> 清除弹出的2次记录图像 ---> 清除棋子2个棋子二维坐标值---> 重新定位显示最后下棋位置并闪烁
主代码介绍
主代码分为二块: 1.界面逻辑块 2.游戏主体块 (界面与游戏代码分离,逻辑清晰,分工明确)
模拟事件通知:游戏主体逻辑块,每次结果都会通知到界面层来进行交互(类似于c#或者java的委托或事件)

AI分析:这个只是最简单的算法,其实很简单,计算每个没有下棋坐标的分数,也是按照 米 字形 计算,计算格子8个方向出现的 一个棋子 二个棋子 三个棋子 四个棋子,其中还分为是否被截断,其实就是边缘是否被堵死。
其实这个AI算法后续还有很多可以优化,比如 断跳 二活 其实就是2个交叉的 活二 , 因为是断掉的所以没有纳入算法权重计算,如果加入这个算法,估计很难下赢电脑了。

因为不是连续的,所有没有纳入。
