如何在 pygame 中的 window 上清除文本

Question

在我正在制作的游戲中。 我正在嘗試解決我在游戲結束時遇到的這個問題。

問題是當你死時它說“你死了”然后我輸入“再玩一次”或“退出”。 如果您按退出顯然它會退出游戲，但如果您再次按播放，我想要它做的是重新運行程序。

def text_objects(text, font):
    textSurface = font.render(text, True, black)
    return textSurface, textSurface.get_rect()

def button(msg, x, y, w, h, ic, ac, action=None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()

    if x + w > mouse[0] > x and y + h > mouse[1] > y:
        pygame.draw.rect(screen, ac, (x, y, w, h))
        if click[0] == 1 and action != None:
            action()
    else:
        pygame.draw.rect(screen, ic, (x, y, w, h))
    smallText = pygame.font.SysFont("comicsansms", 20)
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ((x + (w / 2)), (y + (h / 2)))
    screen.blit(textSurf, textRect)



def quitgame():
    pygame.quit()
    quit()

def dead():
    global dead
    dead = True
    
    while dead:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

        largeText = pygame.font.SysFont("comicsansms", 115)
        TextSurf, TextRect = text_objects("You Died", largeText)
        TextRect.center = ((display_width / 2), (display_height / 2))
        screen.blit(TextSurf, TextRect)

        button("Play Again", 20, 450, 115, 50, green, bright_green, respawn)
        button("Quit", 250, 450, 100, 50, red, bright_red, quitgame)

        pygame.display.update()
        clock.tick(15)

對於我的重生 function。 有人告訴我復制並粘貼我的 while true 循環中的所有內容，並將其全部放入我的重生 function 中，我注意到當你再次按下播放時，音樂和音效正在播放，除了游戲結束屏幕之外的所有內容都是還在玩

如果您需要，這里是重生 function 的代碼

    redrawGameWindow()
    Timetext = font.render('Time elapsed:' + str(round(timeForLevel,1)), 1, (255,251,0))
    screen.blit(Timetext, (20, 10))
    

    pygame.display.update()

謝謝你們的提示，因為你說我應該將變量設置為原始條件。 像這樣

def respawn():
    global dead
    global run
    global velotimeser 
    global timeForLevel 
    global font 
    global man 
    global zombie 
    global zombie1 

    global randomside 
    global gunCapacity 
    global points
    global powerMeter 
    global bullets 
    global intro 
    dead = False
    velotimeser = 1
    timeForLevel = 0
    font = pygame.font.SysFont('comicsans', 30, True)
    man = Player(300, 508, 64, 64)
    zombie = Enemy(100, 508, 64, 64, 450)
    zombie1 = Enemy1(100, 508, 64, 64, 450)

    randomside = 0
    gunCapacity = 1
    points = 0
    powerMeter = 0
    bullets = []
    intro = False

    pygame.mixer.music.play(-1)

    run = True
