如何在一个事件中为Pygame中的不同对象设置多个计时器？

import pygame
from pygame.locals import *

# 初始化Pygame
pygame.init()

# 创建窗口
window = pygame.display.set_mode((800, 600))

# 定义计时器事件的ID
TIMER_EVENT_1 = USEREVENT + 1
TIMER_EVENT_2 = USEREVENT + 2

# 设置计时器
pygame.time.set_timer(TIMER_EVENT_1, 1000)  # 每隔1秒触发一次TIMER_EVENT_1
pygame.time.set_timer(TIMER_EVENT_2, 2000)  # 每隔2秒触发一次TIMER_EVENT_2

# 游戏循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False
        elif event.type == TIMER_EVENT_1:
            # 处理TIMER_EVENT_1事件
            print("TIMER_EVENT_1 triggered")
        elif event.type == TIMER_EVENT_2:
            # 处理TIMER_EVENT_2事件
            print("TIMER_EVENT_2 triggered")

    # 更新游戏逻辑
    # ...

    # 绘制游戏界面
    # ...

    pygame.display.update()

# 退出游戏
pygame.quit()
