How to make player animations work on LAN

Question

I've set up an animation player and an animation tree for the player, along with the movement script. I was wondering how to make those animations work over the network? Here's a snippet of the code

func physicsprocess(delta):
if gettree().hasnetwork_peer():

    if is_network_master():
        var input_vector = Vector2.ZERO
        input_vector.x = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left")

        input_vector.y = Input.get_action_strength("ui_down") - Input.get_action_strength("ui_up")
        input_vector = cartesian_to_isometric(input_vector).normalized()

        if input_vector != Vector2.ZERO:
            velocity = input_vector
            velocity = velocity.move_toward(input_vector * MAX_SPEED, ACCELERATION)

        else:
            velocity = velocity.move_toward(Vector2.ZERO, FRICTION)

        move_and_slide(velocity)
