How can i reverse the direction my enemy is walking on collision with objects tagged as walls in C#?

Here’s the Move Script:

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine;

public class MoveScript : MonoBehaviour 
{
public Vector2 speed = new Vector2(10, 10); 
public Vector2 direction = new Vector2(-1, 0);

void Update ()
    {
    Vector3 movement = new Vector3(speed.x * direction.x, speed.y * direction.y, 0);
    movement *= Time.deltaTime;
    transform.Translate(movement);
    }
}

Add this to your code:

private void OnCollisionEnter2D(Collision2D collision)
	{
		if(collision.collider.CompareTag("WallTag"))
		{
			direction = Vector2.Scale(direction, new Vector2(-1, 0));
		}
	}

You can reverse a direction vector by simply making it minus eg…

-forwardVector or -direction

hope this helps
