用python编写2048程序pythonqq45011837的博客-

一、背景介绍与引用
最近在重温python，加上一点私心，想要编一个有图像界面的2048程序。
我曾经想过在论坛里面找一个类似的，但是搜索了很久都找不到合适的，有的是只有控制台界面，有的实在是不好自制。最终，我找到了一个非常合适的解决方案（下面会放出链接）。但是我只是采用了其中图形界面的设定，具体的算法还有图形我是自己设计的，原因是原作者在规则上与2048有些不符（比如当移动并不改变现在的顺序时，不产生新的随机块）。

Python写2048小游戏全部代码及所用图片

二、源代码
虽然算法是自己写的，但我采用了 @彡楠风丶吹 的源代码方案，把源代码分了三部分：游戏算法、游戏图形和游戏运行。
首先是算法部分：GameCalculation.py，这部分包含了主要的内部算法过程，主要是上下左右移动、添加随机数、游戏规则。其中，上下左右移动的过程是先移动后合并然后再次移动。下面是这部分的代码：

import numpy as np#为了方便，用了矩阵 import random as rd import sys def Up(GameList):#向上移动     NewList1=np.array([[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]])#用两个零矩阵过渡     NewList2=np.array([[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]]) for j in range(4):#先储存非零量在赋值给新列表         NoneZeroList = [] for i in range(4): if GameList[i,j]!=0:                 NoneZeroList.append(GameList[i,j]) for k in range(len(NoneZeroList)):             NewList1[k,j]=NoneZeroList[k] for j in range(4):#相同值合并 for i in range(3): if NewList1[i,j]==NewList1[i+1,j]:                 NewList1[i,j]=NewList1[i,j]*2                 NewList1[i+1,j]=0 for j in range(4):#合并后再移动         NoneZeroList=[] for i in range(4): if NewList1[i,j]!=0:                 NoneZeroList.append(NewList1[i,j]) for k in range(len(NoneZeroList)):             NewList2[k,j]=NoneZeroList[k]     NoneSame=0 for i in range(4): for j in range(4): if GameList[i,j]!=NewList2[i,j]:                 NoneSame=1 break if NoneSame==1: for i in range(4): for j in range(4):                 GameList[i,j]=NewList2[i,j] return 1 else: return 0 def Down(GameList):     NewList1=np.array([[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]])     NewList2=np.array([[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]]) for j in range(4):         NoneZeroList = [] for i in range(-1,-5,-1): if GameList[i,j]!=0:                 NoneZeroList.append(GameList[i,j]) for k in range(len(NoneZeroList)):             NewList1[3-k,j]=NoneZeroList[k] for j in range(4): for i in range(-1,-4,-1): if NewList1[i,j]==NewList1[i-1,j]:                 NewList1[i,j]=NewList1[i,j]*2                 NewList1[i-1,j]=0 for j in range(4):         NoneZeroList=[] for i in range(-1,-5,-1): if NewList1[i,j]!=0:                 NoneZeroList.append(NewList1[i,j]) for k in range(len(NoneZeroList)):             NewList2[3-k,j]=NoneZeroList[k]     NoneSame=0 for i in range(4): for j in range(4): if GameList[i,j]!=NewList2[i,j]:                 NoneSame=1 break if NoneSame==1: for i in range(4): for j in range(4):                 GameList[i,j]=NewList2[i,j] return 1 else: return 0 def Left(GameList):     NewList1 = np.array([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]])     NewList2 = np.array([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]) for i in range(4):         NoneZeroList=[] for j in range(4): if GameList[i,j]!=0:                 NoneZeroList.append(GameList[i,j]) for k in range(len(NoneZeroList)):             NewList1[i,k]=NoneZeroList[k] for i in range(4): for j in range(3): if NewList1[i,j]==NewList1[i,j+1]:                 NewList1[i,j]*=2                 NewList1[i,j+1]=0 for i in range(4):         NoneZeroList=[] for j in range(4): if NewList1[i,j]!=0:                 NoneZeroList.append(NewList1[i,j]) for k in range(len(NoneZeroList)):             NewList2[i,k]=NoneZeroList[k]     NoneSame=0 for i in range(4): for j in range(4): if GameList[i,j]!=NewList2[i,j]:                 NoneSame=1 break if NoneSame==1: for i in range(4): for j in range(4):                 GameList[i,j]=NewList2[i,j] return 1 else: return 0 def Right(GameList):     NewList1 = np.array([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]])     NewList2 = np.array([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]) for i in range(4):         NoneZeroList=[] for j in range(-1,-5,-1): if GameList[i,j]!=0:                 NoneZeroList.append(GameList[i,j]) for k in range(len(NoneZeroList)):             NewList1[i,3-k]=NoneZeroList[k] for i in range(4): for j in range(-1,-4,-1): if NewList1[i,j]==NewList1[i,j-1]:                 NewList1[i,j]*=2                 NewList1[i,j-1]=0 for i in range(4):         NoneZeroList=[] for j in range(-1,-5,-1): if NewList1[i,j]!=0:                 NoneZeroList.append(NewList1[i,j]) for k in range(len(NoneZeroList)):             NewList2[i,3-k]=NoneZeroList[k]     NoneSame=0 for i in range(4): for j in range(4): if GameList[i,j]!=NewList2[i,j]:                 NoneSame=1 break if NoneSame==1: for i in range(4): for j in range(4):                 GameList[i,j]=NewList2[i,j] return 1 else: return 0 def Random2or4(GameList):     ZeroList = []     Count4 = 0 for i in range(4): for j in range(4): if GameList[i, j] == 0:                 ZeroList.append([i, j]) for i in range(4): for j in range(4): if GameList[i, j] == 4:                 Count4 = 1 if Count4 == 0:         RandomNum = rd.choice(ZeroList)         GameList[RandomNum[0], RandomNum[1]] = 2 else:         RandomNum = rd.choice(ZeroList)         GameList[RandomNum[0], RandomNum[1]] = rd.choice([2, 2, 2, 2, 2, 2, 2, 2, 2, 4]) def Rule(GameList):     Temp2048 = np.sum(GameList == 2048)     Temp0 = np.sum(GameList == 0) if Temp2048 != 0: return 1 if Temp0==0:         TempSame=0 for i in range(4): for j in range(3): if GameList[i, j] == GameList[i,j+1]:                     TempSame = 1 break for j in range(4): for i in range(3): if GameList[i,j]==GameList[i+1,j]:                     TempSame = 1 break if TempSame==0: return 0 else: return 2 

然后是图形文件GameImages.py，包含了背景图片、数字对应的图片和胜负的图片。这就是有些借鉴 @彡楠风丶吹 的部分。借鉴是采用了原来的分辨率设定与数字块图片位置与刷新；区别是所有的图片都是我自己重新用PS做的，并且做了圆角处理，还有就是添加了胜负图片。下面是源代码：

import pygame import time import sys class Settings(): def __init__(self): # 屏幕设置         self.screen_width = 400         self.screen_height = 600         self.screen_bg = pygame.image.load('images/bg_1.png')         self.screen_rect = self.screen_bg.get_rect()         self.numlen = 100 def NumImage(num, screen, x, y): if num == 2:         n = pygame.image.load('images/2.png') elif num == 4:         n = pygame.image.load('images/4.png') elif num == 8:         n = pygame.image.load('images/8.png') elif num == 16:         n = pygame.image.load('images/16.png') elif num == 32:         n = pygame.image.load('images/32.png') elif num == 64:         n = pygame.image.load('images/64.png') elif num == 128:         n = pygame.image.load('images/128.png') elif num == 256:         n = pygame.image.load('images/256.png') elif num == 512:         n = pygame.image.load('images/512.png') elif num == 1024:         n = pygame.image.load('images/1024.png') else:         n = pygame.image.load('images/2048.png')     r = n.get_rect()     r.centerx = x     r.centery = y     screen.blit(n, r) def SoFImage(x,screen): if x==0:         n=pygame.image.load('images/2048_Failed.png')         screen.blit(n, (20,175))         pygame.display.update()         time.sleep(1) elif x==1:         n = pygame.image.load('images/2048_Succeed.png')         screen.blit(n, (20, 175))         pygame.display.update()         time.sleep(1) def UpdateScreen(GameList, set, screen):     screen.blit(set.screen_bg, set.screen_rect)     y = set.numlen * 2.5 for i in range(4):         x = set.numlen * 0.5 for j in range(4): if GameList[i,j] != 0:                 NumImage(GameList[i,j], screen, x, y)             x += set.numlen         y += set.numlen 

最后是运行文件GameRun.py，包括键盘操作和游戏开始。键盘操作部分包括判定移动是否有效部分。下面是源代码：

import numpy as np import pygame import GameCalculation as GC import GameImages as GI import sys def Operation(GameList,screen): for event in pygame.event.get(): if event.type == pygame.QUIT:             sys.exit() elif event.type == pygame.KEYDOWN: if event.key == pygame.K_RIGHT: if GC.Right(GameList)==1:                     GC.Rule(GameList) if GC.Rule(GameList)==2:                             GC.Random2or4(GameList)                 GI.SoFImage(GC.Rule(GameList),screen) elif event.key == pygame.K_LEFT: if GC.Left(GameList)==1:                     GC.Rule(GameList) if GC.Rule(GameList)==2:                             GC.Random2or4(GameList)                 GI.SoFImage(GC.Rule(GameList),screen) elif event.key == pygame.K_DOWN: if GC.Down(GameList)==1:                     GC.Rule(GameList) if GC.Rule(GameList)==2:                             GC.Random2or4(GameList)                 GI.SoFImage(GC.Rule(GameList),screen) elif event.key == pygame.K_UP: if GC.Up(GameList)==1:                     GC.Rule(GameList) if GC.Rule(GameList)==2:                             GC.Random2or4(GameList)                 GI.SoFImage(GC.Rule(GameList),screen) def RunGame():     GameList = np.zeros((4, 4), dtype=int) set = GI.Settings()     pygame.init()     screen = pygame.display.set_mode((set.screen_width, set.screen_height))     pygame.display.set_caption("2048            @K1snan")     GC.Random2or4(GameList)     GC.Random2or4(GameList) while True:         Operation(GameList,screen)         GI.UpdateScreen(GameList, set, screen)         pygame.display.update() RunGame() 

三、游戏图形
其实上面已经把代码写完了，自己找一些图片就能运行了，背景图是400×600像素，数字块是90×90像素。我写这一部分就是来把自己的图片展示一下。开头的时候我已经说了，是有一些私心哒，做这个除了重新熟悉一下python外，也是想自己做一个喜欢的偶像的游戏，下面放图。

四、运行演示
下面两张图是运行截图，由于我实在是凑不出2048来，只能给出失败的图了。
