這篇文章主要為大家詳細(xì)介紹了200行Python代碼實(shí)現(xiàn)2048游戲，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

Python實(shí)戰(zhàn)系列用于記錄實(shí)戰(zhàn)項(xiàng)目中的思路，代碼實(shí)現(xiàn)，出現(xiàn)的問(wèn)題與解決方案以及可行的改進(jìn)方向

本文為第2篇–200行Python代碼實(shí)現(xiàn)2048

一、分析與函數(shù)設(shè)計(jì)

1.1 游戲玩法

2048這款游戲的玩法很簡(jiǎn)單，每次可以選擇上下左右滑動(dòng)，每滑動(dòng)一次，所有的數(shù)字方塊都會(huì)往滑動(dòng)的方向靠攏，系統(tǒng)也會(huì)在空白的地方亂數(shù)出現(xiàn)一個(gè)數(shù)字方塊，相同數(shù)字的方塊在靠攏、相撞時(shí)會(huì)相加。（介紹來(lái)自百度百科）

1.2 函數(shù)設(shè)計(jì)

_init _() 初始化4*4游戲地圖，分?jǐn)?shù)等游戲基本數(shù)據(jù)
is_gameover() 判斷是否結(jié)束游戲
rannumber() 玩家每次移動(dòng)時(shí)在地圖上隨機(jī)生成2、4
show() 在控制臺(tái)打印出4*4游戲地圖
print_score() 在控制臺(tái)打印出當(dāng)前分?jǐn)?shù)
up(), upmove() 上移
down(), downmove() 下移
left(), leftmove() 左移
right(), rightmove() 右移
nextstep() 讀取玩家按鍵

二、代碼實(shí)現(xiàn)

注：IDE為Spyder，Python版本為3.6

三、問(wèn)題與解決方案

1.地圖的儲(chǔ)存與表示：目前沒(méi)有界面設(shè)計(jì)，因此就用二維數(shù)組直接儲(chǔ)存與表示

2.數(shù)組越界：調(diào)試代碼中遇到過(guò)五六次，除了牢記要邊緣檢測(cè)外， and 語(yǔ)句左右條件順序也要有講究。

例：while(temp<=2 and self.number[temp+1][j]==0 ) 注：self.number為4*4的二維數(shù)組
當(dāng)temp=3時(shí)，語(yǔ)句在temp<=2 被阻塞，不會(huì)執(zhí)行self.number[temp+1][j]==0，此時(shí)沒(méi)有問(wèn)題;
若語(yǔ)句改為while(self.number[temp+1][j]==0 and temp<=2), 先執(zhí)行self.number[temp+1][j]==0，此時(shí)編譯器報(bào)錯(cuò)數(shù)組越界

四、可行的改進(jìn)方向

1.添加可視化界面，可考慮Tkinter，QT等

2.拓展游戲地圖大小為N x N
