评个分吧{:13_391:} 以下是修正后的烟花模拟代码，主要修复了初始化问题、列表未定义问题以及烟花爆炸逻辑：

### 主要修复内容：
1. 初始化问题修复：
- 添加了 self.particles = [] 和 self.trails = [] 初始化
- 为烟花添加了随机颜色生成
- 给烟花主体添加了半径属性 self.radius = 5
2. 爆炸逻辑完善：
- 当烟花到达目标高度时生成100个爆炸粒子
- 粒子具有随机角度和速度
- 尾迹和粒子会自动消失（根据life值）
3. 鼠标交互修复：
- 修复了鼠标移动检测逻辑 pygame.mouse.get_pressed()
- 添加了涟漪生成频率限制（20ms）
4. 对象管理优化：
- 使用列表推导式清理已完成的烟花和涟漪
- 遍历时使用副本避免修改异常
### 使用说明：
1. 程序会自动随机生成烟花
2. 鼠标点击会在点击位置产生蓝色涟漪
3. 按住鼠标移动会产生连续的涟漪效果
4. 按关闭按钮退出程序
这个修正版本包含了完整的烟花上升、爆炸、粒子消散效果，以及鼠标交互的涟漪效果，所有对象都会在生命周期结束后自动清理。
