python - 在 python 中使用 OOP 定义属性

问题描述

我目前在 python 中使用 OOP 来编写游戏。我创建了一个具有属性和方法的类。我想做基本的移动，如果用户输入“向北”，它将移动到北广场。然而，它说我有一个错误，北方没有定义。这是我的代码：

class square():
    def __init__(self, action, square_no, north, east, south, west):
        
        self.action = action
        self.square_no = square_no
        self.north = north
        self.east = east
        self.south = south
        self.west = west

    def user_action(action):
        action = input("---").lower()

        square.movement(action, north)

    def Help():
        print("Commands are: \n Go(north/ east /south /west) \n Mine \n Craft (object) \n Look around \n Collect (blueprint)\n Fix (wing/ thruster/ engine/ battery/ fuel tank) \n Save \n Info \n You will see this symbol when you are expected to type something ---")
        square.user_action(action)

    def movement(action, north):
             
        if action == "go north":
            print(north)

        elif action == "info":
            square.Help()   
            
        else:
            print("You can't do that here.")
            square.user_action(action)


action = ""

square1 = square(action, 1, 0, 2, 4, 0)
print(square1)

square1.user_action()

谢谢

解决方案

您在各个地方都缺少self代码按预期工作

class square():
    def __init__(self, action, square_no, north, east, south, west):
        
        self.action = action
        self.square_no = square_no
        self.north = north
        self.east = east
        self.south = south
        self.west = west

    def user_action(self):
        action = input("---").lower()

        self.movement(action)

    def Help(self):
        print("Commands are: \n Go(north/ east /south /west) \n Mine \n Craft (object) \n Look around \n Collect (blueprint)\n Fix (wing/ thruster/ engine/ battery/ fuel tank) \n Save \n Info \n You will see this symbol when you are expected to type something ---")
        self.user_action(action)

    def movement(self,action):
             
        if action == "go north":
            print(self.north)

        elif action == "info":
            square.Help()   
            
        else:
            print("You can't do that here.")
            square.user_action(action)


action = ""

square1 = square(action, 1, 0, 2, 4, 0)
print(square1)
square1.user_action()
