我正在做一个游戏，在屏幕上有一个追逐者和一个跑步者（鲍勃和菲尔）。这很像标签。截至目前，如果追赶者与跑步者发生碰撞，游戏将重置，玩家将移回其原始位置。我想添加一个计时器，以便当计时器达到0时，游戏将重置。
我考虑过使用一个名为“ time”的变量，并将其等于60。然后，我将使用time-= 1和time.sleep函数使该变量每秒减1。问题在于time.sleep函数将停止整个程序。有什么方法可以在我的游戏中实现计时器而不会遇到前面提到的问题？

与实际计时器一起，我想在屏幕顶部以文本形式实际显示计时器，但是我很自信在实际添加计时器时会大胆地将其拉下。< / p>

我不熟悉用于创建游戏的软件包，但是我发现这个similar question的答案表明乌龟中有一个ontimer()函数。
这部分特别有趣：
def countdown():
global timer
timer -= 1
if timer <= 0: # time is up, disable user control
wn.onkey(None, 'Left')
wn.onkey(None, 'Right')
wn.onkey(None, 'Up')
wn.onkey(None, 'Down')
# Whatever else you need to do to tell the user its game over
else:
wn.ontimer(countdown, 1000) # one second from now
wn.ontimer(countdown, 1000) # start the timer
因此，该函数仅在设定的毫秒数（即1000，在此情况下为1秒）后调用自身，如果其值为零将禁用控件（根据您的游戏需求进行定制）。
您可以将计时器设置为100毫秒，然后将timer -= 1更改为-= 0.1，以获得更精细的时钟，以用于显示。
只记得在全局位置创建一个计时器。
