如何将文本保留在pygame窗口中一段确定的时间

import pygame
import sys

pygame.init()
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

text = "Hello, World!"
display_time = 5  # 显示时间，单位为秒

font = pygame.font.Font(None, 36)  # 使用默认字体和大小36

text_object = font.render(text, True, (255, 255, 255))  # 白色文本

text_rect = text_object.get_rect()
text_rect.center = (width // 2, height // 2)  # 居中显示

screen.blit(text_object, text_rect)
pygame.display.flip()  # 更新显示

clock = pygame.time.Clock()
start_time = pygame.time.get_ticks()  # 获取当前时间
while True:
    clock.tick(60)  # 设置帧率为60
    current_time = pygame.time.get_ticks()  # 获取当前时间
    if current_time - start_time >= display_time * 1000:  # 判断是否达到显示时间
        break

pygame.quit()
sys.exit()
