对于像 pygame.sprite.spritecollide 这样的碰撞检测功能，使用了 pygame.sprtie.Sprite 对象的 rect 属性。因此，您需要确保在 Enemy
的 rect 属性中设置精灵的位置
self.rect = img[i].get_rect()
self.rect = img[i].get_rect(topleft = (x[i], y[i]))
和Player
self.rect = img.get_rect()
self.rect = img.get_rect(topleft = (self.x, self.y))
注意，pygame.Surface.get_rect.get_rect() returns a rectangle with the size of the Surface object, that always starts at (0, 0) since a Surface object has no position. A Surface is blit at a position on the screen. The position of the rectangle can be specified by a keyword argument. For example, the top left of the rectangle can be specified with the keyword argument topleft. These keyword argument are applied to the attributes of the pygame.Rect before it is returned (see pygame.Rect 关键字参数的完整列表）。
