using System.Collections;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public bool dead = false;
    public float speed;
    private Rigidbody2D rb2d;
    public GameObject[] health;
    public GameObject Hazard;
    public GameObject HealthPickup;
    private bool facingRight;
    private void Start()
    {
        facingRight = true;
        rb2d = GetComponent<Rigidbody2D>();
    }
    void FixedUpdate()
    {
        if (Input.GetKey("w") || Input.GetKey("a") || Input.GetKey("s") || Input.GetKey("d"))
        {//find controller inputs
            float moveHorizontal = Input.GetAxisRaw("Horizontal");
            float moveVertical = Input.GetAxisRaw("Vertical");

            transform.Translate(moveHorizontal * speed * Time.deltaTime, moveVertical * speed * Time.deltaTime, 0);

        }
        else
        {
            float moveHorizontal = Input.GetAxisRaw("JoystickHorizontal");
            float moveVertical = Input.GetAxisRaw("JoystickVertical");

            transform.Translate(moveHorizontal * speed * Time.deltaTime, moveVertical * speed * Time.deltaTime, 0);
            //wowie here im trying
        }

    }
    private void Flip(float moveHorizontal)
    {
        if (moveHorizontal > 0 && !facingRight || moveHorizontal < 0 && facingRight)
        {
            facingRight = !facingRight;
            Vector3 theScale = transform.localScale;
            theScale.x *= -1;
            transform.localScale = theScale;
        }
    }



    public void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Hazard"))
        {
            SendMessage("TakeDamage", 1);
            Destroy(other.gameObject);
        }

        if (other.CompareTag("HealthPickup"))
        {
            SendMessage("Heal");
            Destroy(other.gameObject);
        }
    }
}

I'm sorry if I'm making a stupid mistake somewhere, I am very new to this. Any help would be appreciated. I'm trying to make my 2D character flip by making the x Scale -1 when the character switches direction.

Flip looks like it should work for you. You just need to call it. I would put in a call at lines 24 and 32.

If you add these calls and still have problems, let me know.

Hope this helps,
