如何阻止精灵离开屏幕?

我遇到以下代码问题。我正在创造一个游戏,泡泡射手。泡沫是精灵。我遇到的问题是,当屏幕上出现气泡时,它们会关闭屏幕。相反,我希望他们反弹屏幕并随机移动。我不知道该怎么做。我努力但没有运气。

我的代码:

class Bubble(pygame.sprite.Sprite):
def __init__(self):
    pygame.sprite.Sprite.__init__(self)

    # Load the bubble images from the bubbles folder. The os.path.join is required to open from a folder.
    # Convert_alpha fixes the transparency in the image.
    self.image = pygame.image.load(os.path.join("assets","bubble1.png")).convert_alpha()
    # This resizes the bubbles so that they are smaller.
    self.image = pygame.transform.scale(self.image, (50, 50))

    self.rect = self.image.get_rect()

    self.area = screen.get_rect()
    self.y = random.randrange(1, 1000)

    self.rect.topleft = 500, self.y
    self.rect.topright = 600, self.y


    self.move = random.randrange(1, 5)

def _move(self):
        newpos = self.rect.move((-self.move, 0))

        self.rect = newpos

def update(self):
    self.rect.centerx += self.vx
    self.rect.centery += self.vy
    w, h = self.screen.get_size()
    if self.rect.left < 0 or self.rect.right > w:
        self.vx *= -1
    if self.rect.top < 0 or self.rect.bottom > h:
        self.vy *= -1     

def update(self):
        self._move()
