如何在pygame中比较两个鼠标位置

import pygame

# 初始化Pygame
pygame.init()

# 设置窗口大小
screen = pygame.display.set_mode((800, 600))

# 设置窗口标题
pygame.display.set_caption('Mouse Position Comparison')

# 主循环
running = True
previous_pos = None

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEMOTION:
            current_pos = pygame.mouse.get_pos()
            if previous_pos is not None:
                # 比较当前位置和之前的位置
                if current_pos != previous_pos:
                    print(f"Mouse moved from {previous_pos} to {current_pos}")
            previous_pos = current_pos

    # 更新屏幕显示
    pygame.display.flip()

# 退出Pygame
pygame.quit()
