Python五子棋小游戏实例分享

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

使用的库

pygame、pyautogui

流程简述

1.画棋盘

设置网格间隔40px ，留白 80 px ，与网格横竖线数量 ，初定19 × 19 。

2.鼠标点击

鼠标点击取得坐坐标（x0 , y0），再获得最近的网格上的点（x1 , y1），再将每次动作获得的（x1 , y1 ）放入列表 chess_location 中。

再通过：

chess_location_b = chess_location[0::2]
chess_location_w = chess_location[1::2]

分别获得黑棋和白棋所走过的坐标。

3.判断胜负

这一块网上有很多不同的方法，我为了让大家读懂尽量写的详细了。
首先 ，我们要知道连五有四个方向：竖直 ，水平 ，右上左下 ， 右下左上 。
每次将新落下的子分别进行4个方向的判断，判断是否出现连五及以上。
我使用的方法是：

def result(x): # x 为 chess_location_b 或者 chess_location_w
    # 竖直
    score = []
    for i in range(cell_num): #cell_num = 19
        if [x[-1][0], i ] in x:
            score.append([x[-1][0], i ])
            if score.__len__() >= 5:
                return 1
        else:
            score =[]

大概意思就是最新落下的（x1 , y1）中的竖直方向从上往下检查如果出现黑（白）棋 ，则将出现棋子的坐标加入列表 score 中 ， 如果出现异色棋子或者没有棋子，则清空 score 中的元素 ，如果列表 score 中的元素数量大于等于5个 ，则分胜负 。
如果棋子填满棋盘但是仍没有分出胜负 ，则平局 。
