我使用下面的类制作了子弹列表和精灵列表.如何检测子弹是否与精灵碰撞,然后删除该精灵和子弹？

#Define the sprite class
class Sprite:

    def __init__(self,x,y, name):
        self.x=x

        self.y=y

        self.image = pygame.image.load(name)

        self.rect = self.image.get_rect()

    def render(self):
        window.blit(self.image, (self.x,self.y))


# Define the bullet class to create bullets          
class Bullet:

    def __init__(self,x,y):
        self.x = x + 23
        self.y = y
        self.bullet = pygame.image.load("user_bullet.BMP")
        self.rect = self.bullet.get_rect()

    def render(self):
        window.blit(self.bullet, (self.x, self.y))

我的 collide_rect 函数无法正常工作。当它不应该返回时，它总是返回 True。我尝试在互联网上查找，但没有任何效果对我有用。我认为碰撞矩形不知何故没有使用两个精灵的实际坐标。有人能帮忙吗？

        pygame.sprite.Sprite.__init__(self)

        self.rect = self.image.get_rect()
        self.x = 280
        self.y = 475
        self.col = False
    def update(self):
        gameDisplay.blit(self.image, (self.x,self.y))
        self.rect = self.image.get_rect()

        self.col = pygame.sprite.collide_rect(self,sprite)

        self.x = -(self.time/5) …
