如何添加可显示的高分变量？ [关闭]

Question

在我的游戏中，我创建了一个评分系统，但我正在努力寻找一种方法来存储在再次运行 gameloop 时不会重置的高分。代码如下：

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。我向您展示了上一部分，希望使下一部分更易于阅读。

gameloop()

Answer 1

编辑：之前的回答未能回答问题。

在文件顶部导入pickle模块：

import pickle

在 game_loop() 函数的开头编写以下代码：

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)

最后一行

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!")

如果高分存在，则将其存储或以 0 分创建它。一旦完成游戏循环，如果分数高于高分，则将高分更改为新的价值。

Answer 2

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用作不会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，请在第一行写上不带撇号的“0”。不需要下载或额外的导入。创建一个 .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')
