放慢动画帧会减慢整个游戏帧的速度我该如何解决？ Pygame

我做了一个精灵，我想放慢动画，因为这是我所做的

for some reason its slowing my whole game frame to 1o in the class I set the frame by fp = 10 VIDeo

class snow:
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height
        self.width = width
        self.color = color
        self.fp = 10
        self.clock = pygame.time.Clock()
        self.games = [
        pygame.image.load("key1.png"),
        pygame.image.load("key2.png"),
        pygame.image.load("key3.png"),
        pygame.image.load("key4.png"),
        pygame.image.load("key5.png"),
        pygame.image.load("key6.png"),
        pygame.image.load("key7.png")]
        self.anim_index = 0
        self.rect = pygame.Rect(x,y,height,width)
        self.direction = "idk"
    def draw(self):
        self.rect.topleft = (self.x,self.y)
        if self.direction == "idk":
            window.blit(self.games[self.anim_index],self.rect)
            self.clock.tick(self.fp)
            self.anim_index += 1
            if self.anim_index == len(self.games):
                self.anim_index = 0
