我想在事件发生后从内存中永久删除精灵。使用 self.kill() 不起作用，因为精灵的图像被删除了，但精灵仍然存在。我该怎么做才能将其从内存中永久删除？

我想删除炸弹。如果炸弹碰到玩家，它的图像就会消失，但它仍然存在。现在，只要子弹碰到（不可见的）炸弹，它也会被删除。
要从 Pygame 内存中永久删除精灵并确保它不再与其他精灵交互，您需要确保正确地将其从所有相关组中删除并正确处理精灵的状态。
从您的代码来看，您似乎正在使用self.kill()移除精灵的方法，这是从其所属的所有精灵组中移除精灵的正确方法。但是，为了确保它完全从内存中消失并且不会干扰游戏逻辑，请确保在移除炸弹后也正确处理碰撞检测。
self.kill()
None
这是代码相关部分的更新版本，以确保炸弹已正确从内存中删除：
对现有代码进行以下修改：
bomb_hit_list = pygame.sprite.spritecollide(bomb, bullet_list, True) for bullet in bomb_hit_list: # Remove bomb from groups and set it to None bomb_list.remove(bomb) all_sprites.remove(bomb) bomb = None # Explicitly set to None to avoid using it later
move
Bomb
class Bomb(pygame.sprite.Sprite): def __init__(self): super().__init__() sprite_sheet = SpriteSheet("Untitled.png") self.image = sprite_sheet.get_image(2, 2, 48, 48, WHITE) self.rect = self.image.get_rect() self.active = True # Flag to indicate if the bomb is active def move(self): if not self.active: # If the bomb is not active, do nothing return self.change_y = 2 self.rect.y += self.change_y if self.rect.y > 500: self.kill() self.active = False # Mark as inactive def kill(self): super().kill() # Call the base class kill method self.active = False # Mark as inactive
在处理炸弹的移动或交互之前，请确保正确检查炸弹的状态。您可以使用该active属性来检查炸弹是否仍应在游戏循环中处理。
active
通过active属性管理炸弹的状态，您可以在炸弹被移除后阻止对其执行任何操作。将炸弹设置为None有助于避免引用可能被删除的精灵，确保游戏逻辑正常运行而不会出现错误。
实施这些更改后，你的炸弹应该可以正确地从内存中移除，而不会影响游戏玩法或产生意外行为。
