鼠标之间的秒表 up/down

Question

我试图通过在 while 循环中使用一个简单的秒表来测试鼠标按下和鼠标弹起事件之间的时间。鼠标按下事件工作正常，但是当我松开鼠标以释放鼠标时，秒数继续上升并且不会停止。

from pygame import *
import time
screen = display.set_mode((160, 90))
sec = 0
while True:
    new_event = event.poll()
    if new_event.type == MOUSEBUTTONDOWN:
        while True: # Basic stopwatch started
            time.sleep(1)
            sec += 1
            print(sec)
            # In loop, when mouse button released,
            # supposed to end stopwatch
            if new_event.type == MOUSEBUTTONUP:
                break
    display.update()

我希望秒表在鼠标松开后结束。例如。如果鼠标只是点击，秒数应该是1。如果鼠标按住5秒，应该不会继续超过5。

使用 pygame.time.get_ticks 获取自调用 pygame.init() 以来的毫秒数。
存储MOUSEBUTTONDOWN时的毫秒数，并在主循环中计算时间差：

from pygame import *

screen = display.set_mode((160, 90))

clock = time.Clock()
run = True
started = False
while run:

    for new_event in event.get():
        if new_event.type == QUIT:
            run = False

        if new_event.type == MOUSEBUTTONDOWN:
            start_time = time.get_ticks()
            started = True

        if new_event.type == MOUSEBUTTONUP:
            started = False

    if started:        
        current_time = time.get_ticks()
        sec = (current_time - start_time) / 1000.0
        print(sec)

    display.update()
