在python中使用计时器进行基本游戏

Question

我必须为高中项目创建这个基本游戏。我是python中的计时器的新手。我的代码如下：

import random
from threading import Timer

score = -1
directions = ["RIGHT", "LEFT", "UP", "DOWN"]
accdirection=random.choice(directions)

def timeOut():
    out_of_time = "yes"
    print("TESTING ")

while accdirection:
     TimeLimit = 1   
     score = score + 1    
     accdirection=random.choice(directions)
     print(accdirection)

     out_of_time = "no" 

     t=Timer(TimeLimit,timeOut)
     t.start()

     fast = input()

     if out_of_time == "yes":
         accdirection = None

     if accdirection in directions:
         t.cancel()


         if accdirection == "RIGHT":
             if fast == "d":
                 accdirection = random.choice(directions)
             else:
                 accdirection = None
                 print("Oops, you clicked the wrong key.")


         elif accdirection == "LEFT":
             if fast == "a":
                 accdirection = random.choice(directions)
             else:
                 accdirection = None
                 print("Oops, you clicked the wrong key.")


         elif accdirection == "UP":
             if fast == "w":
                 accdirection = random.choice(directions)
             else:
                 accdirection = None
                 print("Oops, you clicked the wrong key.")


         elif accdirection == "DOWN":

             if fast == "s":
                 accdirection = random.choice(directions)
             else:
                 accdirection = None
                 print("Oops, you clicked the wrong key.")

     else:
         print("Oof, too slow!")
         accdirection = None





print("Your score is:", score)

代码的功能是python输出方向，然后用户必须输入w，a，s或d。如果他们得到了错误的密钥，游戏结束了，他们就输了。这部分工作正常。当时间用完时，它打印出“TESTING”，我只是为了测试它是否进入timeOut函数。但是，感觉out_of_time的值似乎总是保持不变：在这种情况下“不”。因此，accdirection的值无法重置为None以中断循环。如果大多数代码对我的问题毫无用处，我很抱歉。请告诉我如何解决这个问题。

你在out_of_time = "yes"函数中设置timeOut，但永远不会返回out_of_time的更新值。

并且out_of_time最初设置在全局命名空间中，因此请指出，并且您应该获得预期的行为：

def timeOut():
    global out_of_time
    out_of_time = "yes"
    print("TESTING ")
    return out_of_time
