在pygame中更改悬停时矩形的边框

import pygame

pygame.init()

window_size = (800, 600)  # 设置窗口大小
window = pygame.display.set_mode(window_size)  # 创建窗口

rect_pos = (100, 100)  # 矩形初始位置
rect_size = (200, 100)  # 矩形大小
rect = pygame.Rect(rect_pos, rect_size)  # 创建矩形对象

border_color = (255, 255, 255)  # 边框颜色
hover_color = (255, 0, 0)  # 悬停时的边框颜色

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 检测鼠标悬停
    if rect.collidepoint(pygame.mouse.get_pos()):
        rect_color = hover_color
    else:
        rect_color = border_color

    # 更新游戏状态
    # TODO

    # 绘制游戏界面
    window.fill((0, 0, 0))  # 清空窗口
    pygame.draw.rect(window, rect_color, rect)  # 绘制矩形边框
    pygame.display.flip()  # 更新屏幕显示

pygame.quit()
