如何在pygame中停止计时器

Question

对于我的结束屏幕，我想要一条写着“你幸存了 X 秒”的行，但在该行中，计时器在游戏结束后继续运行。

我尝试在主循环中将计时器代码向下移动（在该if gameover:部分之后）。我也尝试过if not gameover and time_difference >= 1500:，但计时器仍然运行。

这是我的带有计时器的程序循环：

Code is removed for now. Will re-upload in 1 to 2 months.

和结束屏幕代码（如有必要）：

def gameOverScreen():

    ending = 1

    global run, gameover

    for event in pygame.event.get():

        if event.type == pygame.QUIT:

            run = False

Answer 1

对于那些需要它的人，在一些帮助下，代码现在可以工作了。#Start screen Loopdone = Falsestart_time = pygame.time.get_ticks()while not done and display_instructions:    if not pygame.mixer.music.get_busy():        pygame.mixer.music.load('bgm.mp3')        pygame.mixer.music.play()    for event in pygame.event.get():        if event.type == pygame.QUIT:            done = True        if event.type == pygame.MOUSEBUTTONDOWN:            instruction_page += 1            if instruction_page == 2:                display_instructions = False    # Set the screen background    win.fill(black)    if instruction_page == 1:        text = font.render("Instructions:", True, white)        win.blit(text, [10, 20])        text = font.render("1.

start_time) // 1000    ending = 1您需要做的是找到发生碰撞时的时间（当碰撞为真时）并将其作为参数传递给 gameOverScreen()。if collide:    gameover = True    end_time = pygame.time.get_ticks()并且 gameOverScreen 应该接收参数 end_time 并使用它来显示秒def gameOverScreen(end_time):    seconds_survived = (end_time - start_time) // 1000请记住，这只有效，因为“如果碰撞”只有一次为真，如果重复为真，则 end_time 将在循环中不断更新，您将再次看到相同的秒数增加情况。希望这对某人有所帮助！
