Pygame 说视频系统未初始化

Question

我是 pygame 新手，我一直在尝试制作 Wordle 游戏。这个函数特别有缺陷，我认为这是因为我使用 while true 循环，它说视频系统未初始化 (pygame.display.update() 和 pygame.event.get()) 但我不知道如何解决这个问题。

def playgame():
    global t_score 
    screen.fill("White")
    row = []
    newgame = Word()
    screen.blit(header,header_rec)
    newgame = getgame()    
    row.append(Box(100,100,120,space_)) 
    row.append(Box(100,100,260,space_)) 
    row.append(Box(100,100,400,space_)) 

    row[0].makerow()
    row[1].makerow()
    row[2].makerow()

    meaning_text = font_smaller.render(f'Meaning: {newgame.meaning}',True,"Black")
    meaning_rec = meaning_text.get_rect(center=(325,576))
    screen.blit(meaning_text,meaning_rec)
    screen.blit(keyboard,keyboard_rec)
    score_text = font_score.render(f'Total score: {t_score}',True,"Black")
    score_text_rec = score_text.get_rect(center=(35,19))
    screen.blit(score_text,score_text_rec)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:

        pygame.display.update()

这个函数应该显示标题和键盘，在添加 if 语句之前它工作得很好，现在它卡在主页上。该函数还应该循环，直到输入一个字母为止，这对于其他 4 个字母也是如此。每个单词还有五次尝试。尝试完成后，或者如果猜测正确，它应该故意停留在同一个窗口上，显示祝贺消息或抱歉消息，并询问用户是否想通过按回车键玩另一个游戏。

错误

Answer 1

pygame 必须先初始化才能使用。

确保您正在使用：

pygame.init()

在代码的开头。
