Hello,

Here is a script to do that. I’ve added more cases so you can do extra stuff when the direction change. Just add it on your sprite gameobject and set the PolyNavAgent reference.

using UnityEngine;

using System.Collections;

public class Flipper : MonoBehaviour {

public PolyNavAgent agent;

private Vector2 lastDir;

private float originalScaleX;

void Awake(){

originalScaleX = transform.localScale.x;

}

void Update() {

var dir = agent.movingDirection;

var x = Mathf.Round(dir.x);

var y = Mathf.Round(dir.y);

y = Mathf.Abs(y) == Mathf.Abs(x)? 0 : y;

dir = new Vector2(x, y);

if (dir != lastDir){

if (dir == Vector2.zero){

Debug.Log("IDLE");

}

if (dir.x == 1){

Debug.Log("RIGHT");

var scale = transform.localScale;

scale.x = originalScaleX;

transform.localScale = scale;

}

if (dir.x == -1){

Debug.Log("LEFT");

var scale = transform.localScale;

scale.x = -originalScaleX;

transform.localScale = scale;

}

if (dir.y == 1){

Debug.Log("UP");

}

if (dir.y == -1){

Debug.Log("DOWN");

}

lastDir = dir;

}

Let me know if this works for you.
Cheers!
