I am creating a snake game with food teleporting around map. I use ontimer with recursion at the end of function to emulate mole staying at a certain position for a time. I also make the mole to move if turtle ate it. But then, mole teleportation is called two time because of the already set function by ontimer.

def mole_teleport(is_loop=True):
        rand_x = random.randint(-250, 250)
        rand_y = random.randint(-250, 250)
        mole.teleport(rand_x, rand_y)
        if is_loop == False:
            return
        else:
            screen.ontimer(mole_teleport, 3000)

tim = Player() #user_turtle
mole = Turtle("circle")

mole_teleport()

screen = Screen()
screen.setup(600, 600)

screen.listen()
screen.onkey(tim.turn_left, "Left")
screen.onkey(tim.turn_right, "Right")

game_is_on = True
while game_is_on:
    tim.move()
    if mole.distance(tim) < 20:
        mole_teleport(is_loop=False)

I tried to block recursion with argument. What I expect is teleportation timer to be refreshed from start after the turtle has eaten the mole and call mole_teleportation()
