Could someone please help with making an enemy sprite flip when going the other way?

Question

Hi I am in the process of making a 2d platformer and have got a simple enemy sprite who I have managed to get moving back and forth, but I am really having issues with getting the sprite to flip when going the other direction. I have tried various different ways but I have a feeling that the movement script I am using makes it difficult. I have spent the last 4 hours trying to get this to work and have become very frustrated! This is the script I am using to move him and I have tried adding a flip function but the sprite goes crazy when he reaches the point where he should flip. using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class GroundEnemyMove : MonoBehaviour
 {
 
     private Vector3 posA;
     private Vector3 posB;
     private Vector3 nextpos;
     public bool facingLeft;
     [SerializeField]
     public float speed;
     [SerializeField]
     private Transform Enemy;
     [SerializeField]
     private Transform transformB;
     // Use this for initialization
     void Start()
     {
         posA = Enemy.localPosition;
         posB = transformB.localPosition;
         nextpos = posB;
     }
 
     // Update is called once per frame
     void Update()
     {
         Move();
     }
 
     void Flip()
     {
         facingLeft = !facingLeft;
         Vector3 theScale = transform.localScale;
         theScale.x *= -1;
         transform.localScale = theScale;
     }
 
     private void Move()
     {
         Enemy.localPosition = Vector3.MoveTowards(Enemy.localPosition, nextpos, speed * Time.deltaTime);
         if (Vector3.Distance(Enemy.localPosition, nextpos) <= 0.1)
         {
             ChangeDestination();
         }
 
 
         }
 
     private void ChangeDestination()
     {
         nextpos = nextpos != posA ? posA : posB;
         transform.position = nextpos;
         Flip();
     }
 
 
 }

Have you checked here? https://docs.unity3d.com/ScriptReference/SpriteRenderer-flipX.html

I would try something along the lines of, If the enemy has a velocity below 0(he would move left), then flip the image

Thanks for the response I tried to play around with your suggestion but it became more complicated as I needed to add RigidBody for the direction and I couldn't get it to work. I have managed it now based from your suggestion with the SpriteRenderer and incorporating it into my existing flip function.

     void Flip()// This makes him turn at the end of each distance
     {
         if (nextpos == posA)
         {
             groundenemy.flipX = true;
         }
         if (nextpos == posB)
         {
             groundenemy.flipX = false;
         }

Thanks for the response. I tried to play around with your suggestion but found myself getting bogged down in rigidbody2d and it seemed to get more and more complicated (and still didn't work!). I have managed it now though using the sprite renderer and the positioning.

void Flip()// This makes him at the end of each distance { if (nextpos == posA) { groundenemy.flipX = true; } if (nextpos == posB) { groundenemy.flipX = false; }
