Pygame蛇食物發生器

我目前正在創建一個蛇遊戲的過程中，我想創建一個食物發生器，根據我的遊戲中的定時器每隔10秒產生一個蘋果。計時器從60減少到0（遊戲結束時），我希望每10秒鐘產生一個新的蘋果，即使沒有吃過，也保留舊的蘋果。我不知道如何解決這個問題，並可以使用一些幫助。這是我的完整程序。Pygame蛇食物發生器

您應該使用蛇類來保存它的屬性。 –

這是一個學校項目，我們的班級還沒有。 – user1832834

噢，好的。基本上，您可以使用'random.randint（）'函數生成2個隨機數，然後在該位置放置一個蘋果。很抱歉地說，但如果你想要多個蘋果，你（幾乎）不得不使用一個類。其他方法可能會非常難看/困難。 –

你要麼

A）使用pygame.time.set_timer調用一個函數每10秒產卵的食物，每60秒結束的一輪。

或

B）比較get_ticks（）

DEF new_round（）： last_apple = pygame.time.get_ticks（）+ 10 * 1000

而真：現在= pygame.time.get_ticks（）

if now - last_apple >= 1000: 
    spawn_apple() 
    last_apple = now 


if now - round_start >= 60*1000: 
    round_end()
