Текстовая приключенческая игра зацикливается на предыдущей строке?
Я изучаю Python, создавая текстовую приключенческую игру. Мне было трудно понять, могу ли я вызвать предыдущую переменную. Например, это фрагмент моего кода (совет о том, как консолидировать, было бы полезно, ха-ха). У меня есть оператор if, который позволяет игроку выбрать вход.
Под входом ЧУЖЕГО вы увидите, выберут ли они 1. Они выбирают "Принять поражение".
У меня есть тот же результат в конце этого кода, чтобы игрок снова выбирал "Принять поражение" после ввода IMPROV. Я хотел бы вернуться к первой инопланетной переменной, если выбрана эта опция. Вместо того, чтобы писать то же самое, если, элиф, снова и снова. Это возможно?

Вы, кажется, не используете функции вообще. Это то, что вы должны сделать:)
Например, вместо того, чтобы повторять цвета ввода каждый раз, сделайте colored_input:
def colored_input():
return input(Fore.YELLOW + Style.BRIGHT + "> ")
alien = colored_input()
Во-вторых, я бы объединил "события" вместо того, чтобы печатать их, как вы. Например, я бы хранил страницы отдельно в кортеже. Вот так:
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)
Тройные кавычки создают многострочную строку. Обратите внимание, что первая и последняя новая строка является частью строки, поэтому вам придется избавиться от нее позже.
Конечно, вы можете поместить текст в кортеж напрямую:
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?
""")
Теперь, если у вас есть куча таких "событий", у вас может быть функция для их отображения и запроса ввода на том же шаге:
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()
Это значительно упростит ваш код. Предполагая, что вы определили все события заранее, вы можете сделать if так:
door = run_event(EVENT_DOOR)
if door == "1":
alien = run_event(EVENT_ALIEN)
if alien == "1":
improv = run_event(EVENT_IMPROV)
...
elif alien == "2":
...
Вы могли бы развить это дальше, например, использовать список вместо многострочной строки для вариантов выбора и связывать события с вариантами выбора.
Но, чтобы ответить на ваш первоначальный вопрос: структурированный таким образом, вы можете превратить части игры в функции. Вот так:
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 ...:
...
Когда вы вызываете функцию из той же самой функции, вы используете рекурсию. На самом деле это довольно плохое решение: например, если вы решите "принять поражение" более 128 или более раз подряд, вы превысите предел рекурсии и ваша программа потерпит крах.
Но чтобы избежать рекурсии, вам придется переработать вашу программу более глубокими способами. ISTM на вашем уровне квалификации, это решение отлично работает. Вы можете узнать больше, когда вы достигнете пределов этого подхода - или когда вы почувствуете, что понимаете этот код очень хорошо и хотите больше проблем:)
Я бы порекомендовал сделать тип графика. Вам придется наметить все варианты, но вы, вероятно, уже должны это сделать. Кроме того, реализация цикла поможет обработать неприемлемые ответы.
Одна жизнеспособная возможность (проверьте это здесь, к вашему сведению, это даже не так полно, как в примере с OP, но вы можете ввести 1 дважды, чтобы увидеть, как это должно происходить):
# 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
