本文介绍了在pygame中如何进行精灵和精灵组之间的碰撞检查，包括精灵与精灵组、精灵组与精灵组的碰撞。通过使用`spritecollide()`和`groupcollide()`函数，实现飞机大战中子弹与飞机的碰撞检测，并根据碰撞结果调整飞机的HP值。文章还提及了子弹消失、爆炸效果的实现，以及字典操作在碰撞检测中的应用。

目标：精灵和精灵组，精灵组和精灵组之间的碰撞检查。

精灵和精灵组自己的碰撞检查用到一个简单的函数。

spritecollide(sprite, group, dokill, collided=None)

查看sprite.py源代码

def spritecollide(sprite, group, dokill, collided=None):
    """find Sprites in a Group that intersect another Sprite

    pygame.sprite.spritecollide(sprite, group, dokill, collided=None):
        return Sprite_list

    Return a list containing all Sprites in a Group that intersect with another
    Sprite. Intersection is determined by comparing the Sprite.rect attribute
    of each Sprite.

    The dokill argument is a bool. If set to True, all Sprites that collide
    will be removed from the Group.

    The collided argument is a callback function used to calculate if two
    sprites are colliding. it should take two sprites as values, and return a
    bool value indicating if they are colliding. If collided is not passed, all
    sprites must have a "rect" value, which is a rectangle of the sprite area,
    which will be used to calculate the collision.

    """
    if dokill:

        crashed = []
        append = crashed.append

        if collided:
            for s in group.sprites():
                if collided(sprite, s):
                    s.kill()
                    append(s)
