Question

我正在开发一款游戏，该游戏使用向左和向右键移动太空飞船，并使用空格键发射子弹，但是按下空格键会使游戏崩溃。我不知道是什么原因造成的。

这是我的代码：

这是错误

TypeError: add() argument after * must be an iterable, not Settings

Answer 1

Bullet中的__init__函数大写，这意味着它不会覆盖默认的Sprite组。因此，您实际上是在调用Sprite __init__函数，并且您要传递ai_settings（一个Settings对象）作为*groups参数。

class Bullet(Sprite):
    """A Class To Manage Bullets Fired From The Ship"""
    def __init__(self, ai_settings, screen, ship): # Notice lowercase
        super().__init__()
        ...

当我尝试在pygame中发射子弹时，我的游戏崩溃了
