基于文本的冒险游戏循环到上一行？
Text-based adventure game looping to previous line?
我正在通过创建基于文本的冒险游戏来学习 Python。我很难弄清楚我是否可以调用以前的变量。例如，这是我的代码片段（关于如何合并的建议会很有帮助哈哈）我有一个 if 语句允许玩家 select 输入。
在ALIEN输入下，你会看到他们是否select 1.他们选择"Accept defeat"。
我在这段代码的末尾有相同的结果，让玩家在 IMPROV 输入后再次选择 "Accept defeat"。如果选择了该选项，我想循环回到第一个 alien 变量。而不是重复编写相同的 if、elif 语句。这可能吗？

我建议制作一种图表。您必须规划出所有选项，但您可能已经这样做了。此外，实现循环将有助于处理不可接受的答案。
一种可行的可能性（测试它 here，仅供参考，这甚至不如 OP 示例那么完整，但您可以输入 1 两次以查看它应该如何进行）：
# make a class for each event, it'll contain a description and any number of choices
class Event:
def __init__(self,description,choices,options):
self.description=description
self.choices=choices
# options should be a list the same length as choices with corresponding keys to other events
self.options=options
def to_string(self):
print(self.description+'\n')
for choice in self.choices:
print(choice+'\n')
# point to the next event
return self.options[self.make_choice()-1]
def make_choice(self):
c=0
# this won't allow a user to enter a value not offered
while c<1 or c>len(self.choices):
c=int(input("your choice> "))
return c
# this is your map
events={'start':Event("You approach the knife slowly, While the alien is distracted. You finally reach the knife, but as you look up, the alien stares back at you.\nYou make a move to stab the alien, but he is too quick.

Get up and continue onward through this seemingly dangerous world?"],['communicate','onward']),'communicate':Event("You take a deep breath, still in pain, you slowly limp your way towards the alien.\nAs the alien hears you approach, it stops eating the arm and turns towards your direction.\nWhat should you say?",["1.

c='start'
while True:
t=events[c].to_string()
# this is how you'd break the loop if you win or lose
if t=="Game Over":
break
elif t=="You Win":
break
c=t
你似乎根本不会使用函数。那是你应该做的事情:)
例如，不是每次都重复输入颜色，而是制作 colored_input:
def colored_input():
return input(Fore.YELLOW + Style.BRIGHT + "> ")
alien = colored_input()
其次，我会合并 "events"，而不是像您一样将它们打出来。例如，我会将页面单独存储在一个元组中。像这样：
STARTING_TEXT = """
Theres an alien eating what appears to be a human arm, though its so damaged it's hard to be sure. There is a knife next to the alien.
what do you want to do?¨
"""
STARTING_CHOICES = """
Go for the knife
Attack alien before it notices you
"""
EVENT_START = (STARTING_TEXT, STARTING_CHOICES)
三引号创建多行字符串。请注意，第一个和最后一个换行符是字符串的一部分，因此您稍后必须将其删除。
当然，你也可以直接将文本放入元组中：
EVENT_APPROACH_KNIFE = ("""
You approach the knife slowly, While the alien is distracted. You finally reach the knife, but as you look up, the alien stares back at you.
You make a move to stab the alien, but he is too quick. With one swift motion, the alien thrusts you into the air.
You land hard, as the alien makes it's way towards you again. What should you do?
""", """
Accept defeat?
Last ditch effort?
""")
现在，如果你有一堆像这样的 "events"，你可以有一个功能来显示它们并在同一步骤中要求输入：
def run_event(event): # from here on, the "event" variable will be whichever EVENT_* you call
text, choices = event # separates the two items of the tuple
# Remove whitespace from start and end. This gets rid of the starting and ending newline
# that I mentioned earlier:
# (go ahead, remove the following line and see what happens)
text = text.strip()
# Now let's get individual lines - split the text on newlines:
text_lines = text.split("\n")
# print them with colors:
for line in text_lines:
print(Fore.YELLOW + line)
print() # To print an empty line, you don't even need to add the ""
# now let's do the same with choices:
choices = choices.strip()
choice_lines = choices.split("\n")
for num, line in enumerate(choice_lines):
# the "enumerate" gives you "num" as the number of the line
# but it counts from 0, so we need to add 1
# (and wrap it in str() because otherwise you can't add it to a string
print(Fore.GREEN + Style.BRIGHT + str(num + 1) + ". " + line)
print()
# finally, ask for player's choice and return it
return colored_input()
这将大大简化您的代码。假设你事先定义了所有的事件，你可以像这样做：
door = run_event(EVENT_DOOR)
if door == "1":
alien = run_event(EVENT_ALIEN)
if alien == "1":
improv = run_event(EVENT_IMPROV)
...
elif alien == "2":
...
您可以进一步开发它，例如，使用列表而不是多行字符串作为选项，并将事件关联到选项。
但是，回答你原来的问题：这样的结构，你可以把游戏的一部分变成函数。像这样：
def accept_defeat():
improv = run_event(EVENT_ACCEPT_DEFEAT)
if improv == "1":
...
elif improv == "2":
wall = run_event(EVENT_LAST_DITCH)
if wall == "1":
accept_defeat() # here you're calling the same function again!
elif ...:
...
# and then somewhere in the main function:
def main():
alien = run_event(EVENT_ALIEN):
if alien == "1":
accept_defeat()
elif ...:
...
当您从同一个函数中调用一个函数时，您使用的是递归。实际上，这是一个相当糟糕的解决方案：首先，如果您决定连续 "accept defeat" 超过 128 次左右，您将超过 递归限制 并且您的程序会崩溃。
但是为了避免递归，您将不得不以更深层次的方式重新编写您的程序。 ISTM 在你的技能水平，这个解决方案工作正常。当您达到这种方法的极限时，或者当您觉得自己非常理解这段代码并想要更多挑战时，您可以学到更多 :)

# but it counts from 0, so we need to add 1
# (and wrap it in str() because otherwise you can't add it to a string
print(Fore.GREEN + Style.BRIGHT + str(num + 1) + ". " + line)
print()
# finally, ask for player's choice and return it
return colored_input()
这将大大简化您的代码。假设你事先定义了所有的事件，你可以像这样做：
door = run_event(EVENT_DOOR)
if door == "1":
alien = run_event(EVENT_ALIEN)
if alien == "1":
improv = run_event(EVENT_IMPROV)
...
elif alien == "2":
...
您可以进一步开发它，例如，使用列表而不是多行字符串作为选项，并将事件关联到选项。
但是，回答你原来的问题：这样的结构，你可以把游戏的一部分变成函数。像这样：
def accept_defeat():
improv = run_event(EVENT_ACCEPT_DEFEAT)
if improv == "1":
...
elif improv == "2":
wall = run_event(EVENT_LAST_DITCH)
if wall == "1":
accept_defeat() # here you're calling the same function again!
elif ...:
...
# and then somewhere in the main function:
def main():
alien = run_event(EVENT_ALIEN):
if alien == "1":
accept_defeat()
elif ...:
...
当您从同一个函数中调用一个函数时，您使用的是递归。实际上，这是一个相当糟糕的解决方案：首先，如果您决定连续 "accept defeat" 超过 128 次左右，您将超过 递归限制 并且您的程序会崩溃。
但是为了避免递归，您将不得不以更深层次的方式重新编写您的程序。 ISTM 在你的技能水平，这个解决方案工作正常。当您达到这种方法的极限时，或者当您觉得自己非常理解这段代码并想要更多挑战时，您可以学到更多 :)
