Python五子棋小游戏实例分享

本文为大家分享了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 。
