Followpath2D and animation switching

Question

HI
I'm trying to get the ghost animation to change when he follows a path but the position returned is always (0,0) or the rotation is always 0. Its an isometric map.

Does anyone have ideas or can tell me how they do it.

the code I'm tying to use is

extends KinematicBody2D

var direction = Vector2()
var currentdirection = Vector2(0,0)

# Called when the node enters the scene tree for the first time.
func _ready():
    set_physics_process(true)

func _physics_process(delta):
    var dir = position
    var direction = dir.normalized()
    print(position)

    ghost_anim(dir)
    # Moves Ghost
    get_parent().set_offset(get_parent().get_offset() + 250 * delta)


func ghost_anim(direction):
    var spritedir
    if currentdirection != direction:
        if currentdirection == Vector2(-1,-1):
            spritedir = "Back_Left"
        elif currentdirection == Vector2(1,-1):
            spritedir = "Back_Right"  
        elif direction == Vector2(-1,1):  
            spritedir = "Front_Left"
        elif direction == Vector2(1,1):  
            spritedir = "Front_Right"
        else:
            pass
    else:
        spritedir = "Front_Left"

    get_node("Ghost").set_animation(spritedir)

    currentdirection = direction
    return currentdirection
