Changing the player sprite when going back and forward Need help :D

Unity Engine
1

I just started making my 2d platformer game and i would like to change the players sprite from facing right to left when you go either right or left.

2

public bool IsFacingRight;

void Update () {
//here is your movement controller
//if your player is walking Right, make boolean ------------ IsFacingRight = true;
//if left ------------ IsFacingRight = false;
//if switch direction call funktion for flip ------------- Flip ();

private void Flip ()
{
IsFacingRight = ! IsFacingRight;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}

i dont know what controller you use :slight_smile: Open new scene, drag your sprite to the scene. Add to it box collider 2d, add rigidbody2d. Set rigidbodies Gravity Scale 0 (in editor, we have no ground or it fall down). Make c# script with name PlayerMove (or choose name, but change the script public class “PlayerMove” <------ this line ).

using UnityEngine;
using System.Collections;

public class PlayerMove : MonoBehaviour
{

        public bool IsFacingRight = true;
        public float Power;

        // Use this for initialization
        void Start ()
        {

        }

        // Update is called once per frame
        void Update ()
        {

                if (Input.GetKeyDown ("a")) {
                        rigidbody2D.AddForce (new Vector2 (-Power, rigidbody2D.velocity.y));
                        if (IsFacingRight) {
                                IsFacingRight = false;
                                Flip ();
                        }
                }

                if (Input.GetKeyDown ("s")) {
                        rigidbody2D.AddForce (new Vector2 (Power, rigidbody2D.velocity.y));
                        if (!IsFacingRight) {
                                IsFacingRight = true;
                                Flip ();
                        }

                }
        }

        private void Flip ()
        {
                Vector3 theScale = transform.localScale;
                theScale.x *= -1;
                transform.localScale = theScale;
        }
}

add script to your sprite object.

set in unity editor Power 100, check or uncheck IsFacingRight your sprite depended

Try a or s Keys.

if you invert scale x of sprite (set -1), so you can change sprite direction.

or just say what controller you need, so i can try to change the script.
