我正在使用 VSCode 使用 pygame 和 python 3.10.0 創建一個游戲，一切正常，但是這個 if 陳述句在一段時間后停止作業并且字體沒有繪制，但我無法確定問題所在，對于 if 陳述句它通常運行到 10 或 11 分，但它可以更快，如 2：
if player.rect.colliderect(food):
pygame.sprite.Sprite.kill(food)
food.rect.x = random.randrange(20, 1700)
food.rect.y = random.randrange(20, 860)
all_sprites_list.add(food)
score = 1
print(score)

uj5u.com熱心網友回復：
kill食品物件沒有必要。改變食物的位置就足夠了。pygame.sprite.Sprite.kill只是從所有Gorups 中洗掉Sprite物件。因此，呼叫然后將物件添加回Group是沒有意義的。kill
文本不顯示，因為您在清除顯示之前繪制它。用純色pygame.Surface.fill填充Surface。之前繪制的所有內容都將被清除。blit之后的文字fill。如果分數發生變化，
您將不得不再次渲染文本Surface。
我建議簡化移動播放器的代碼。請參閱按住鍵時如何進行精靈移動。
