怎么使用Python+Pygame實(shí)現(xiàn)走四棋兒游戲

今天小編給大家分享一下怎么使用Python+Pygame實(shí)現(xiàn)走四棋兒游戲的相關(guān)知識(shí)點(diǎn)，內(nèi)容詳細(xì)，邏輯清晰，相信大部分人都還太了解這方面的知識(shí)，所以分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后有所收獲，下面我們一起來了解一下吧。

一、游戲解說

“走四兒”大部分活躍在山東濟(jì)南、聊城、菏澤等地，是一種棋類游戲，特別適合兒童試玩。

在一個(gè)4×4的棋盤上，雙方各有4子，分別擺放在棋盤兩個(gè)最上面的兩端線的四個(gè)位置上。下圖

就是“走四兒”開局的樣子。

二、游戲規(guī)則

“走四兒”的游戲規(guī)則是：

1．雙方輪流走，每一步只能在上下左右中的一個(gè)無子的方向上走一個(gè)格，不能斜走。如果一方無法移動(dòng)，則由另一方走。

2．當(dāng)甲方的一個(gè)子移動(dòng)到一條線上之后，這條線上只有甲方的兩個(gè)子和乙方的一個(gè)子，且甲方的這兩子相連，乙方的子與甲方那兩子中的一個(gè)子相連，那么乙方的這個(gè)子就被吃掉。

下圖是可以吃子的樣式例舉：

3．少于2個(gè)子的一方為輸者。雙方都無法勝對(duì)方就可以認(rèn)為是和棋。

三、環(huán)境安裝

 1）素材（圖片） 

 2）運(yùn)行環(huán)境 小編使用的環(huán)境：Python3、Pycharm社區(qū)版、Pygame、 numpy模塊部分自帶就不一一 展示啦。 

模塊安裝：pip install -i https://pypi.douban.com/simple/+模塊名
