python - “pygame 错误”: font not initialized.。在已使用的字体上？

Question

这是一个奇怪的问题，因为我已经在同一个执行过程中使用了该字体，并且......在同一个函数中!

我用我的程序的一部分来解释自己:

def text(show_text, show_size, show_color, show_x, show_y):
    fontObj = pygame.font.Font('Font.ttf',show_size)                # The line 43
    Load_text = fontObj.render(show_text,True,show_color,None)
    render_text  = Load_text.get_rect()
    render_text.center = (show_x,show_y)
    screen.blit(Load_text,render_text)

def checkmouse(t_text,size,px,py,color1,color2,window):
    global p_x, p_y
    px_min = px - (int(len(str(text))/2))
    px_max = px + (int(len(str(text))/2))
    py_min = py - 10
    py_max = py + 10
    if p_x >=  px_min and p_x <= px_max and p_y >= py_min and p_y <= py_max :
       text(t_text,size,color1,px,py)  # The line 68
       pygame.display.update()
    else:
       text(t_text,size,color2,px,py)
       pygame.display.update()

问题就在这里:

    if w == 'main':
        sceen=pygame.display.set_mode((1920,1080), pygame.NOFRAME)
        while w == 'main':
            image(bg32_big,0,0)
            Main = True
            while Main :
               checkmouse('Play',32,960,260,Dark_Blue,White,'load') # line 109
               checkmouse('Quit',32,1520,740,Dark_Blue,White,'load')

这是我的“回溯”:

Traceback (most recent call last):
  File "C:\Users\Cédric\3D Objects\_TAL WIP_\TAL 1 script\newfile.py", line 143, in <module>
    Window('main')
  File "C:\Users\Cédric\3D Objects\_TAL WIP_\TAL 1 script\newfile.py", line 109, in Window
    checkmouse('Play',32,960,260,Dark_Blue,White,'load')
  File "C:\Users\Cédric\3D Objects\_TAL WIP_\TAL 1 script\newfile.py", line 68, in checkmouse
    text(t_text,size,color2,px,py)
  File "C:\Users\Cédric\3D Objects\_TAL WIP_\TAL 1 script\newfile.py", line 43, in text
    fontObj = pygame.font.Font('Font.ttf',show_size)
pygame.error: font not initialized

但这怎么可能呢？在同一个函数中，我之前使用过 text('正在加载，这可能需要一些时间...',15,Dark_Blue,240,240) 并且效果很好，那为什么呢？

只是不要在主循环中调用pygame.quit():

       while Main :
           checkmouse('Play',32,960,260,Dark_Blue,White,'load')
           checkmouse('Quit',32,1520,740,Dark_Blue,White,'load')
           for event in pygame.event.get():
                if event.type == pygame.MOUSEBUTTONDOWN:
                     Window(window) 
           pygame.quit() # <-- don't do this

它会将字体模块(和其他模块)置于不再可用的状态。
