如何在Pygame中注册一次鼠标点击？

import pygame

pygame.init()

screen = pygame.display.set_mode((width, height))

pygame.display.set_caption("游戏标题")

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN:
            # 处理鼠标点击事件
            pos = pygame.mouse.get_pos()
            print("鼠标点击位置：", pos)
        elif event.type == pygame.QUIT:
            running = False

pygame.display.flip()

elif event.type == pygame.QUIT:
    running = False

import pygame

# 初始化Pygame
pygame.init()

# 创建窗口
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

# 设置游戏标题
pygame.display.set_caption("游戏标题")

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN:
            # 处理鼠标点击事件
            pos = pygame.mouse.get_pos()
            print("鼠标点击位置：", pos)
        elif event.type == pygame.QUIT:
            running = False

    # 更新窗口显示
    pygame.display.flip()

# 退出游戏
pygame.quit()
