如何在pygame中知道空格键是否被按下超过2秒

import pygame
import time

pygame.init()

clock = pygame.time.Clock()

space_pressed = False

start_time = 0

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                space_pressed = True
                start_time = time.time()  # 记录按下空格键的开始时间

    # 判断空格键是否被按下超过2秒
    if space_pressed and time.time() - start_time > 2:
        print("空格键被按下超过2秒")

    # 游戏逻辑和绘制代码

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

pygame.quit()
