谁借莪１个温暖的怀抱￠ 2024-03-30 13:29 125阅读 0赞

*2022年圣诞节到来啦，很高兴这次我们又能一起度过~*

### 一、前言 ###

本文我们用 `Python` 来画一棵带背景音乐效果的雪夜圣诞树以及使用 `HTML+CSS+JS` 在页面渲染出动态圣诞树，所涉及到的源码均来自`GitHub`开源站点。

### 二、效果展示 ###

#### Python ####

### 三、编码实现 ###

#### Python代码 ####

import pygame
    import random
    
    # 初始化 pygame
    pygame.init()
    # 设置屏幕宽高，根据背景图调整
    bg_img = "bg.png"
    bg_size = (609, 601)
    screen = pygame.display.set_mode(bg_size)
    pygame.display.set_caption("雪夜圣诞树")
    bg = pygame.image.load(bg_img)
    # 雪花列表
    snow_list = []
    for i in range(150):
        x_site = random.randrange(0, bg_size[0])   # 雪花圆心位置
        y_site = random.randrange(0, bg_size[1])   # 雪花圆心位置
        X_shift = random.randint(-1, 1)         # x 轴偏移量
        radius = random.randint(4, 6)           # 半径和 y 周下降量
        snow_list.append([x_site, y_site, X_shift, radius])
    # 创建时钟对象
    clock = pygame.time.Clock()
    # 添加音乐
    track = pygame.mixer.music.load('my.mp3')  # 加载音乐文件
    pygame.mixer.music.play()  # 播放音乐流
    pygame.mixer.music.fadeout(600000)  # 设置音乐结束时间
    done = False
    while not done:
        # 消息事件循环，判断退出
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                done = True
        screen.blit(bg, (0, 0))
        # 雪花列表循环
        for i in range(len(snow_list)):
            # 绘制雪花，颜色、位置、大小
            pygame.draw.circle(screen, (255, 255, 255), snow_list[i][:2], snow_list[i][3] - 3)
            # 移动雪花位置（下一次循环起效）
            snow_list[i][0] += snow_list[i][2]
            snow_list[i][1] += snow_list[i][3]
            # 如果雪花落出屏幕，重设位置
            if snow_list[i][1] > bg_size[1]:
                snow_list[i][1] = random.randrange(-50, -10)
                snow_list[i][0] = random.randrange(0, bg_size[0])
        # 刷新屏幕
        pygame.display.flip()
        clock.tick(30)
    # 退出
    pygame.quit()
