将秒表添加到pygame中的游戏

Question

我想在我的pygame中添加一个秒表。我打算修改此代码并添加到我的pygame中：

Sec += 1
print(str(Min) + " Mins " + str(Sec) + " Sec ")
if Sec == 60:
    Sec = 0
    Min += 1
    print(str(Min) + " Minute")

我应该在def init 部分中添加计时器框并为计时器代码创建新的def吗？我想让计时器不使用代码滴答，因为我的游戏正在运行clock.tick（60），所以它不会影响滴答声

Answer 1

如果您的游戏以60 fps的速度在while循环上运行，则可以通过以下操作获得分钟和秒钟的时间：

frame_count = 0
frame_rate = 60

... while block of game running 60 fps

    # Every second passes 60 frames, so you get seconds by dividing
    # by 60
    seconds = total_seconds // 60

    # Because 1 second is 60 frames, minute is 60 seconds * 60 frames.
    # So you divide by 60 * 60 = 3600 
    minutes = total_seconds // 3600  # Because every second is 60 fps 

    output_string = "Time: {0:02}:{1:02}".format(minutes, seconds)

    frame_count += 1

Answer 2

例如，您可以使用pygame.time.get_ticks()来获取自pygame.init()被调用以来的毫秒数，然后使用简单的除法来从该数字中获取秒和分钟等。

这是一个简单的例子：

import pygame
import pygame.freetype

def main():
    pygame.init()
    screen=pygame.display.set_mode((400, 300))
    clock=pygame.time.Clock()
    font=pygame.freetype.SysFont(None, 34)
    font.origin=True
    while True:
        for e in pygame.event.get():
            if e.type == pygame.QUIT: return
        screen.fill(pygame.Color('grey12'))
        ticks=pygame.time.get_ticks()
        millis=ticks%1000
        seconds=int(ticks/1000 % 60)
        minutes=int(ticks/60000 % 24)
        out='{minutes:02d}:{seconds:02d}:{millis}'.format(minutes=minutes, millis=millis, seconds=seconds)
        font.render_to(screen, (100, 100), out, pygame.Color('dodgerblue'))
        pygame.display.flip()
        clock.tick(60)

if __name__ == '__main__': main()

如果您想让秒表“稍后开始”，您可以在此时存储pygame.time.get_ticks()的输出，并从进一步的调用结果中减去它（例如starttime=pygame.time.get_ticks()和{ {1}}，然后在循环中，您会明白的。）
