Python3中基于文本的冒险

Question

我正在研究一个基于文本的RPG，但是我发现了很多问题，比如：

• 进店后不能去任何地方
• 由于某种原因，我无法进入“酒馆”；以及
• 计算机只显示"buy is not defined in crossbow"。在

代码：

gold = int(100)

# spend 30 points on strenght, health, wisdom, dexterity 
# player can spend and take points from any attribute

classic = {"Warrior",
         "Archer",
         "Mage",
         "Healer"}
print("Choose your race from", classic,)
classicChoice = input("What class do you choose: ")

基于Kevin的回答，这里有一个压缩了冗余的版本，因此您可以通过在顶部附近添加一个新的def go_xyz(): ...来添加一个新的位置。在

def go_shop():
    print("Welcome to the shop!")
    #...etc

def go_tavern():
    print("You enter the tavern...")
    #...etc

def go_forest():
    print("You enter the forest...")
    #etc

places = {name[3:]:globals()[name] for name in globals() if name.startswith('go_')}
placenames = ', '.join(places)

inventory = ['book']
retry = False

while True:
    if not retry:
        print("Here is your inventory: ", inventory)
    else:
        print("I do not know that place")
    print("Where do you wish to go?")
    print("Possible places: ", placenames, '.')
    choice = input("? ")
    try:
        places[choice]()
        retry = False
    except KeyError:
        retry = True

当你第一次在第111行询问用户去哪里时，如果他们除了输入“shop”之外还输入了其他内容，会发生什么情况？那么第119行的if choice == "shop":条件将失败，buy = input("...")将永远不会执行。此时，buy不存在，因此当下一个条件执行时，它会崩溃，因为它无法计算if buy == "crossbow"。buy没有值，因此无法将其与任何内容进行比较。在

您需要缩进所有的shop逻辑，以便它位于if choice == "shop"块中。在

if choice == "shop":
    print("Welcome to the shop!")
    print("You have", gold,"gold")
    buy = input("What would you like to buy? A crossbow, a spell or a potion: ")

    if buy == "crossbow":
        print("this costs 50 gold")
        #...etc
    if buy == "spell":
        print("this costs 35 gold")

同样的问题也存在于你的酒馆代码中。即使你不去酒馆，你也要检查tavernChoice。这也需要缩进。在

^{pr2}$

在这一点上，你的程序将结束，但我猜你想继续探索领域。您可以将所有内容放入while循环中，从第一个input命令开始。在

while True:
    print("Here is your inventory: ", inventory)
    print("What do you wish to do?")
    print("please input shop, tavern, forest.")
    choice = input("Go to the shop, go to the tavern, go to the forest: ")

    if choice == "shop":
        print("Welcome to the shop!")
        #...etc

    elif choice == "tavern":
        print("You enter the tavern...")
        #...etc

    elif choice == "forest":
        print("You enter the forest...")
        #etc

    else:
        print("Not acepted")
        print("What do you wish to do?")
        print("please input shop, tavern, forest.")

这也比您当前的方法更简洁，因为您只需询问用户一次他们要去哪里，而不是在第112、165和170行询问三次。在
