Pygame评分打开和写入文件

Question

我的游戏有问题，假设游戏中的分数是3，然后我试着写一个高于10的分数。它不写我一直试图修复的文件，但它不起作用。。请帮忙。以下只是代码的一部分

# Variables within loop
loop = True
over = False
# car
carx = int(display_w/2 - 20)
cary = 500
carwidth = 40
carheight = 70
cxchange = 0
# obstacle
obx = carx - carwidth
oby = -200
obwidth = random.randint(200, 450)
obheight = random.randint(100, 200)
obychange = 0
obstacle_speed = 7
# score appending
readhighscore = open("score.txt", "r")
highscore = readhighscore.read()
while loop:
    if over == True:
        message_to_screen("Game over!", black, -200, "large")
        message_to_screen("Final Score: " + str(score), black, -130, "small")
        fire_explosion(carx + int(carwidth / 2), cary)
        if str(score) > str(highscore):
            writehighscore = open("score.txt", "w")
            writehighscore.write(str(score))
        pygame.display.update()
    while over:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                cxchange += 4
            elif event.key == pygame.K_LEFT:
                cxchange -= 4
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_RIGHT:
                cxchange = 0
            elif event.key == pygame.K_LEFT:
                cxchange = 0
    # Movement
    carx += cxchange
    oby += obychange
    obychange = obstacle_speed
# If Statements
    # end of map and if the car successfully dodges the obstacle
    if carx >= display_w - carwidth:
        carx = display_w - carwidth
    elif carx <= 0:
        carx = 0
    if oby > display_h:
        if score > 16:
            obwidth = random.randint(300, 450)
        else:
            obwidth = random.randint(200, 450)
        obx = carx - random.randint(0, 100)
        oby = random.randint(-1000, -500)
        score += 3
    # obstacle collision with the car
    if oby+obheight >= cary and oby <= cary+carheight:
        if carx+carwidth >= obx and carx <= obx + obwidth:
            over = True
            obychange = 0
    # score concept
    print(highscore)
# Drawing
    # background color
    gameDisplay.fill(white)
    # car
    gameDisplay.blit(car1, [carx, cary])
    # obstacle
    drawobjects(obx, oby, obwidth, obheight, blue)
    # score
    drawScore(score)
    pygame.display.update()
    clock.tick(FPS)

下面的代码应该完全可以工作，虽然我不太确定你的问题是什么。在

with open("score.txt", "w") as f:
    f.write(str(score))

那只是我的头顶。
编辑：还有很多不必要的代码。读https://stackoverflow.com/help/mcve，他们的关键词是最小的。在

新用户： 抱歉，我有一段时间没有活动，但无论如何。。。 问题就在这条线上：

if str(score) > str(highscore):

或者，换句话说，您正在比较字符串。用int代替str，你会没事的。在这种情况下，你不能做比字符串更大的事情的原因是复杂的。但是如果你想要一个解释，请看这个：String Comparison Technique Used by Python
