這是一個打字小游戲。點擊play按鈕，螢屏頂端開始下落隨機的字母，敲擊鍵盤對應的鍵，該字母消失。現在已經完成了大部分的代碼，但是存在一個問題：點擊play按鈕，程式沒有啟動。我發現問題可能在game_functions.py的check_play_button()方法的if play_button.rect.collidepoint(mouse_x , mouse_y):因為注釋掉這一句，stats.game_active就變成True了，但是沒有這句條件陳述句，點擊螢屏任何地方都會改變stats.game_active的值為True。這不是我想要的效果。請幫忙看看如何解決？謝謝！
代碼如下：（有點長，但是是一項挑戰）
1. alphaget_zoo.py

pygame.display.set_caption("Alphabet Zoo")
play_button = Button(screen, "Play")
stats = GameStats(az_settings)
letters = pygame.sprite.Group()
start = time.time()
sleepTime = 3
while True:
now = time.time()
gf.check_events(letters, stats, play_button)
if stats.game_active:
gf.update_screen(az_settings, stats, screen, letters, play_button)
