Question

所以我刚刚学会了如何使用类，我创建了这个类，但是我不能让它运行我使用

spacecraft1 = spacecraft(500,500,100,34)

上课然后在循环中我使用spacecraft1.motion()来更新/移动。从这一切我得到错误：

Traceback (most recent call last):
  File "C:\Users\Redstone3\Desktop\Desctop\Centers\game5\gameBuild 0.04.py", line 107, in <module>
    spacecraft1 = spacecraft(500,500,100,34)
TypeError: 'pygame.Surface' object is not callable

并且可以同时创建40个这样的宇宙飞船，而不是像

那样定义它们的每个人

spacecraft1 = spacecraft(500,500,100,34)
spacecraft2 = spacecraft(500,500,100,34)
spacecraft3 = spacecraft(500,500,100,34)
spacecr...

这是我的课程，如果它有所帮助。此类和主游戏文件位于单独的文件中，但位于相同的文件夹中。

鉴于错误显示“表面对象不可调用”，这意味着在您的函数中某个位置，您认为您正在实例化航天器的实例，您之前已经创建了一个包含覆盖该类的pygame.Surface对象的局部变量来自全球范围的“航天器”。你的类不是问题所在，它是你试图实例化它的函数中的前一个代码。

e.g。

 class spacecraft:
   ...

 def someOtherFunction:
    ...
    # this valid line of code is actually where the problem 
    # is as it hides your spacecraft class with a local variable instead.
    spacecraft = some pygame.Surface instance
    ...
    spacecraft1 = spacecraft(...)
    ...

类给出错误而不是运行？
