文本RPG库存系统-全局错误

问题描述

RPG库存无法正常运行。 对不起，如果我的代码太糟糕了，我才开始学习Python。

的Python 3.7.0

闲置3.6。 （64位）

崇高文字3.1.1。（3176）

#firstly I created classes for items and items_in_body_parts.
#for example, one of them:
class item_for_put_on:
    def __init__(self):
    self.name = ''
    self.body_part = '' #for what body part? like in Diablo, for example, you can take a weapon in your hand and put on a helmet on your head
#there is a lot of other staff, i deleted it to make it simple, here are the main things:
right_hand_item_1 = right_hand_item() 
on_head_item_1 = on_head_item() 
item_for_put_on_1 = item_for_put_on() 
item_check_on = item_check_on_class()

    #here was some code - to describe to player all content of the bag - it works good

                    break
                elif com5.lower() in ['equip', 'eq']:
                    item_for_put_on_1.name = all_item_names[i][0]

                break
            else: 
                print('test looping') #loop while going to this again and again, searching for the correct name of item in dictionary all_item_names
                if ppp == '' and action4 == '':
                    break
    elif action4.lower() == 'back':
        #inventory_menu()

def inventory_eq():
    #we come here from inventory menu to see what is equipped on our hero
    #global right_hand_item_1, on_head_item_1 ---- should be globals here?
    print("right arm - " + str(right_hand_item_1.name) + "\n")
    print("head - " + str(on_head_item_1.name) + "\n")
    #SO HERE WE CAN SEE WRONG INFO --- if you put on only one thing, everything is right, but if you put on the second thing - there will be two sticks (one on head, one in hand) or two helmets (one on head, one in hand)

所以在这里我们可以看到错误的信息：如果只穿一件东西，那一切都是对的，但是如果穿第二件东西，那将有两根棍棒（一个在头上，一个在手）或两个头盔（一个在头上） ，一个在手）； 由于项目名称存在问题。 而且，如果我为其添加更多的物品和插槽，最后一个将是例如Shield-英雄的身体上将会有很多盾牌，而不是正确的物品。 当然，库存中没有以前的物品。

在我看来，问题出在全局变量的某个地方，或者while循环在某个地方效果不好（也许我永远不知道每秒分配一次）。

看来，当我们更改item_for_put_on_1时，它会更改所有已分配的内容-函数item_put_on（）中的on_head_item_1和right_hand_item_1。

如果我在装备完物品后在item_put_on（）中使用了item_for_put_on_1的清零功能（使其成为=''），它将以某种方式从设备中删除物品的名称

因此，主要问题与item_for_put_on_1有关，但我需要帮助以找到解决问题的方法。
