在我的游戏中，我创建了一个评分系统，但我很难找到一种方法来存储在gameloop再次运行时不会重置的高分。这是代码：
import pygame
import time
import random
import timeit
pygame.init()
display_width = 1600
display_height = 850
speed = [1, -1]
black = (0,0,0)
white = (255,255,255)
red = (255, 0, 0)
grey = (177,177,177)
blue = (0,0,255)
green = (0,255,0)
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('Kill hitler before he gets trump')
clock = pygame.time.Clock()
crosshairImg = pygame.image.load('crosshair.PNG')
hitlerImg = pygame.image.load('hitler.png')
donaldImg = pygame.image.load('donald.png')
def crosshair(x, y):
gameDisplay.blit(crosshairImg, (x,y))
def enemy(x, y):
gameDisplay.blit(hitlerImg, (x,y))
def friendly(x, y):
gameDisplay.blit(donaldImg, (x,y))
def message_display(text):
largeText = pygame.font.Font('freesansbold.ttf',45)
TextSurf, TextRect = text_objects(text, largeText)
TextRect.center = ((display_width/2),(display_height/2))
gameDisplay.blit(TextSurf, TextRect)
pygame.display.update()
def text_objects(text, font):
textSurface = font.render(text, True, red)
return textSurface, textSurface.get_rect()
def status(total, enemy_kills):
if total == 0:
status = 0
else:
status = round((enemy_kills/total)*100, 2)
font = pygame.font.SysFont(None, 25)
text = font.render('Status:'+str(status)+'%', True, blue)
gameDisplay.blit(text,(0,30))
def score(count):
font = pygame.font.SysFont(None,25)
text = font.render('Confirmed Enemy Kills:'+str(count), True, blue)
gameDisplay.blit(text,(0,0))
def timer(count):
count = round(count, 1)
font = pygame.font.SysFont(None,25)
text = font.render('time left:'+str(count), True, blue)
gameDisplay.blit(text,(0,45))
def friend_kill(count):
font = pygame.font.SysFont(None,25)
text = font.render('Confirmed Friendly Kills:'+str(count), True, blue)
gameDisplay.blit(text,(0,15))
我认为以下部分代码需要编辑。我向你展示了以前的内容，希望能让下一部分更容易阅读。

答案 0 :(得分：1)
修改：之前的回答无法回答问题。
在文件顶部导入pickle模块：
import pickle
在game_loop（）函数的开头写下以下代码：
try:
with open("var.pickle", "rb") as file:
high = pickle.load(file)
except (OSError, IOError) as e:
high = 0
with open("var.pickle", "wb") as file:
pickle.dump( high, file)
最后在行
之前message_display('you got '+str(kills)+' enemy kills and '+str(friendly_kills)+' friendly kills')
time.sleep(2)
添加以下内容：
if high < kills:
with open("var.pickle", "wb") as file:
pickle.dump(high, open("var.pickle", "wb"))
message_display("New High-score!")
如果存在高分，或者得分为0，则会得到高分。一旦你完成游戏循环，如果分数高于高分，你将高分改为新分数。值。
答案 1 :(得分：0)
将高分存储在名为highscore.txt的单独.txt文件中。 .txt文件是可以存储字符串但也可以用作不被删除的数据的文件。确保您的.txt文件与游戏文件位于同一目录中。要启动它，请写下＆＃39; 0＆＃39; 0在没有撇号的第一行。不需要下载或额外导入。创建.txt文件并在游戏循环中执行此操作：
File = open(highscore.txt, 'r') #Out of game Loop
HighScore = int(File.read())
if kills > HighScore: #In game loop
File.truncate()
File.close()
File = open(highscore.txt, 'w')
File.write(kills)
File.close()
File = open(highscore.txt, 'r')
