在pygame中实现计时器

import pygame
import sys

pygame.init()

window_size = (800, 600)
window = pygame.display.set_mode(window_size)
pygame.display.set_caption("计时器")

clock = pygame.time.Clock()
font = pygame.font.Font(None, 36)

start_time = pygame.time.get_ticks()
is_running = True

while is_running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            is_running = False

    current_time = pygame.time.get_ticks() - start_time
    seconds = current_time // 1000
    minutes = seconds // 60
    hours = minutes // 60

    timer_text = "{:02}:{:02}:{:02}".format(hours, minutes % 60, seconds % 60)
    timer_surface = font.render(timer_text, True, (255, 255, 255))

    window.fill((0, 0, 0))
    window.blit(timer_surface, (10, 10))

    pygame.display.flip()
    clock.tick(60)

pygame.quit()
sys.exit()
