我目前正在制作数学游戏,用户有60秒的时间来回答尽可能多的问题。截至目前,除了计时器之外我还能正常工作,计时器应该倒数到0或计数到60然后停止游戏。现在,我将计时器设置为time.clock()以计数到60,而当计时器小于该计时器时,游戏将继续运行。但是出于某种原因,time.clock()并不像我期望的那样工作。我也尝试同时运行两个while循环,但这两个循环都没有用。有人能帮帮我吗?只是想找一种在后台运行计时器的方法。
这是我的代码:
score = 0
timer = time.clock()
lives = 3
while timer < 60 and lives > 0:
if score >= 25:
x = random.randint(-100,100)
y = random.randint(-100,100)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
elif score >= 20:
x = random.randint(-75,75)
y = random.randint(-75,75)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
elif score >= 15:
x = random.randint(-50,50)
y = random.randint(-50,50)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
elif score >= 10:
x = random.randint(-25,25)
y = random.randint(-25,25)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
elif score >= 5:
x = random.randint(-10,10)
y = random.randint(-10,10)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
elif score >= 0:
x = random.randint(-5,5)
y = random.randint(-5,5)
answer = int(raw_input("What is %d + %d? " % (x,y)))
if answer == x + y:
print "Correct!"
score += 1
else:
print "Wrong!"
lives -= 1
if lives == 0:
print "Oh no! You ran out of lives! Your score was %d." % score
elif timer == 60:
print "Time's up! Your score is %d." % score
else:
print "Goodbye!"

使用time.time()
,它返回纪元时间(即自1970年1月1日以来的秒数UNIX Time)。您可以将其与开始时间进行比较以获得秒数:
start = time.time()
while time.time() - start < 60:
# stuff
您可以让计时器在任何时候(即使用户输入信息)将信号从您的代码中拉出来,但信号稍微复杂一些。一种方法是使用信号库:
import signal
def timeout_handler(signal, frame):
raise Exception('Time is up!')
signal.signal(signal.SIGALRM, timeout_handler)
这定义了一个引发异常的函数,并在超时发生时调用。现在,您可以将while循环放在try catch块中并设置计时器:
signal.alarm.timeout(60)
try:
while lives > 0
# stuff
except:
# print score
