Python代码函数未正确更新变量

我试图做一个简单的基于文本的房间游戏，你可以从一个房间到另一个房间，它会给你一个描述，你可以四处走动。输入1后，输出相应工作。在它要求您再次输入并且您输入了一个方向之后，程序什么也不做。 我在前面的代码中定义了不同的room1、room2等。我认为这与我的方向函数和xy变量有关，但我不完全确定问题出在哪里

import time
import sys
x=1
y=1
def direction():
    global x
    global y

    prompt = input("\nChoose a direction using AWSD:\n")
    if prompt == "a" or prompt == "A":
        x -= 1
    elif prompt == "s" or prompt == "S":
        y -= 1
    elif prompt == "w" or prompt == "W":
        y += 1
    elif prompt == "d" or prompt == "D":
        x += 1

def stutter(text):
    for c in text:
        print(c, end="")
        sys.stdout.flush()
        time.sleep(.04)
stutter(""""You wake up in a dark room with a rusty iron door. There is a small
circular window casting a dim light across the room. Theres two doors leading
out. One forward and one to the right.""")
direction()






if x==1 and y==1:
    stutter(room1)
    direction()
elif x==1 and y==2:
    stutter(room2)
    direction()
elif x==1 and y==3:
    stutter(room3)
    direction()
elif x==2 and y==1:
    stutter(room4)
    direction()
elif x==2 and y==2:
    stutter(room5)
    direction()
elif x==2 and y==2:
    stutter(room6)
    direction()
elif x==3 and y==1:
    stutter(room7)
    direction()
elif x==3 and y==2:
    stutter(room8)
    direction()
elif x==3 and y==3:
    stutter(room9)
    direction()
else:
    stutter("You hit a wall")
    direction()

您必须引入一个

while

循环，如下所示：

while(True):
    if x==1 and y==1:
        stutter(room1)
    elif x==1 and y==2:
        stutter(room2)
    elif x==1 and y==3:
        stutter(room3)
    elif x==2 and y==1:
        stutter(room4)
    elif x==2 and y==2:
        stutter(room5)
    elif x==2 and y==2:
        stutter(room6)
    elif x==3 and y==1:
        stutter(room7)
    elif x==3 and y==2:
        stutter(room8)
    elif x==3 and y==3:
        stutter(room9)
    else:
        stutter("You hit a wall")
    direction()

否则它只请求一次，因为不再调用

stutter（）

另一方面，你应该试着理解数组，可能还有dict，因为它们可以摆脱那一长串的坐标检查。

整个

如果elif

部分必须包含在一个无限循环中，

direction（）

调用必须被删除，除了第一个（也包括在循环中）。
