你好我在尝试运行我的游戏时遇到错误（TypeError）我不知道为什么这样带来堆栈溢出这里是代码：

Game().run()
这是我似乎得到的错误。我不清楚它为什么会发生（我之前从未遇到过这种情况）
Traceback (most recent call last):
File "F:\My Moon Survival Game\Moon Survival.py", line 183, in <module>
Game().run()
TypeError: __init__() takes exactly 4 arguments (1 given)
[Finished in 0.2s with exit code 1]
任何帮助将不胜感激，谢谢。

当您致电Game()时，会依次调用__init__方法。
您的init方法需要3个参数（self除外）：
def __init__( self, x, y, direction ) :
这是问题的原因。
在旁注中，您将x，y，direction作为参数，但从不使用它。您可能想要删除它们。

游戏类需要3个参数 - x，y，direction（+ self）
class Game():
def __init__(self, x, y, direction):
但你创建没有参数的对象
Game().run()
您似乎不需要这些参数，所以请使用
class Game():
def __init__(self):
答案 2 :(得分：1)
Game.__init__参数外， x还需要3个附加参数（y，direction和self）。你的电话应该是
Game(100, 100, "north").run()
或对3个必要参数有意义的任何内容。
答案 3 :(得分：1)
在编写代码时，您正在执行
Game().run()
你的构造函数是
def __init__(self, x, y, direction):
然后你运行的脚本只有一个参数（self），在创建对象时被调用，但x，y和direction没有被传递，你需要像
这样的东西Game(some_x, some_y, some_direction).run()
我希望这对你有所帮助
