一位Python新手修改了dodger游戏（链接：inventwithpython.com/dodger.py），…
2. 解决方案
- 在 # Add new baddies_type_1 at the top of the screen, if needed. 代码后，添加 baddies_type_1.append(newbaddie_type_1) 将坏人添加到列表中。
- 在 # Add new goddies_type_1 at the top of the screen, if needed. 代码后，添加 goddies_type_1.append(newgoddie_type_1) 将奖励添加到列表中。
- 将代码中的 goodies 拼写统一改为 goddies。
以下是纠错后的代码：
