Не работает перемещение персонажа на Pygame

Есть такой кусок кода, который должен перемещать игрока на определенные координаты:

def win(self):
     self.teleporting(55, 55)

def teleporting(self, goX, goY):
     self.rect.x = goX
     self.rect.y = goY

Потом вызываю его в функции:

def collidefg(self, flegs):
    for f in flegs:
        if sprite.collide_rect(self, f):
            self.win()
            f.kill()
            flegs.clear()
            

Подскажите почему не работает?
