1. 实现效果

2. 素材加载

2个图片和3个音频

shoot_image = pygame.image.load('shoot(已去底).jpg') # 加载拼接的发射图像
flower_image = pygame.image.load('flower.jpg')      # 加载拼接的烟花图 烟花不好去底
# 调整图像的像素为原图的1/2 因为图像相对于界面来说有些大
shoot_image = pygame.transform.scale(shoot_image, (shoot_image.get_size()[0]/2 ,shoot_image.get_size()[1]/2))
flower_image = pygame.transform.scale(flower_image, (flower_image.get_size()[0]/2 ,flower_image.get_size()[1]/2))
# 音频、音效
shoot_sound = pygame.mixer.Sound('shoot.mp3')
bomb_sound = pygame.mixer.Sound('bomb1.mp3')
bg_music = pygame.mixer.Sound('bg.mp3')

图像分块显示

# 每个部分的宽度
num_parts = 10  # 有10个shoot图
num_parts1 = 13 # 13个烟花
shoot_part_width = shoot_width // num_parts
flower_part_width = flower_width // num_parts1

3. 烟花发射

发射shoot图从底部往上，快到顶部变烟花flower，然后下落一段距离，最后消失。

4. 画面定格

处理鼠标点击事件以暂停和恢复动画
