Pygame 时钟不准确

Question

我正在尝试制作玩具熊的五夜后宫 "fan game"，但时钟部分不工作。我有一个名为 'time' 的函数，每帧设置一次运行。它计算程序运行的帧数，当它等于 40（我以 40 fps 的速度运行ning）时，它向变量 'seconds' 加 1，当秒数等于一定数量时，小时将改变。有3个问题：

当摄像头升起时（将鼠标移动到屏幕底部），新的时间图像将覆盖旧图像，但是一旦您将摄像头放回原处（只需将鼠标移到屏幕底部）屏幕底部）它恢复正常。

时间不准确。就像我之前提到的，我有它，所以小时每 10 秒就会改变一次。问题是当我计时时，小时之间的时间不一致（即需要 15 秒才能更改为 1:00，然后需要 18 秒才能更改为 2:00，然后需要 17 秒才能更改为3:00，依此类推。）

最后一个问题是 6:00 图像永远不会被块化。该程序没有用 6:00 图像替换 5:00 图像，而是简单地 blitts 没有图像来显示 5:00.

之后的小时

我的代码如下：

import pygame, random
pygame.init()

screen = pygame.display.set_mode((0,0), pygame.FULLSCREEN, 32)
pygame.display.toggle_fullscreen()
clock = pygame.time.Clock()

twelve = pygame.image.load('images/12.png')
one = pygame.image.load('images/1.png')
two = pygame.image.load('images/2.png')

four = pygame.image.load('images/4.png')
five = pygame.image.load('images/5.png')
six = pygame.image.load('images/5.png')

office_pic = pygame.image.load('images/office.png')
stage = pygame.image.load('images/stage.jpg')
building_map = pygame.image.load('images/map.png')
building_map.convert_alpha()

def time():
    global fps_tick, seconds, hour
    fps_tick += 1

    if fps_tick == 40:
        seconds += 1
        fps_tick = 0

    if seconds == 10:
        hour += 1
        seconds = 0


    #blit the hour
    if hour == 1:
        screen.blit(twelve, ((screen_width-150), 30))
    elif hour == 2:
        screen.blit(one, ((screen_width-150), 30))

    elif hour == 6:

    elif hour == 7:
        screen.blit(six, ((screen_width-150), 30))

            x_move = -12
        else:

    x -= x_move

    while True:       

        for event in pygame.event.get():

如果您想每 10 秒执行一次操作，最好使用 pygame 的事件系统并简单地使用 pygame.time.set_timer.

安排用户事件

例如，

pygame.time.set_timer(pygame.USEREVENT, 10000)

将每 10 秒触发一次 pygame.USEREVENT 事件。你像听主循环中的每个事件一样听它：

...
for event in pygame.event.get():
    if event.type == pygame.KEYDOWN:
       if event.key == pygame.K_ESCAPE:
            pygame.quit()
            quit()
    if event.type == pygame.USEREVENT:
        hour += 1
...

如果你仔细观察，就会明白为什么图像在 five 和 six 之间没有变化：你使用了相同的图像。

...
five = pygame.image.load('images/5.png')
six = pygame.image.load('images/5.png')
...
