snake and ladder flip

I am following a tutorial on snake and ladder puzzle game on udemy. i have a problem flipping the 2d player. how can i flip the player i have tried many methods but it doesnt work. i want to flip the player when it moves. i am a noob so any help please. script here : using System.Collections; using System.Collections.Generic; using UnityEngine; public class Stone : MonoBehaviour { public Route route; public List nodeList = new List(); int routePosition; int stoneId; //player id float speed = 3f; int stepsToMove; int doneSteps; bool isMoving; AudioSource audiosrc; SpriteRenderer sp; Rigidbody rb; float cTime=0; float amplitute=0.5f; void Start() { sp = GetComponent(); rb = GetComponent(); audiosrc = GetComponent(); foreach(Transform c in route.nodeList) { Node n = c.GetComponentInChildren(); if(n!= null) { nodeList.Add(n); } } } IEnumerator Move() { if(isMoving) { yield break; } isMoving = true; Debug.Log("ismoving"); nodeList[routePosition].RemoveStone(this);

        while(stepsToMove>0)
        {
           routePosition++;
           Vector3 nextPos = route.nodeList[routePosition].transform.position;
            
             //Arc Movement
             Vector3 startPos = route.nodeList[routePosition-1].transform.position;
 
    while (MoveInArcToNextNode(startPos,nextPos,4f))
           {
               yield return null;
           }
 
           yield return new WaitForSeconds(0.1f);
 
            cTime=0;
 
            stepsToMove--;
            doneSteps++;
            Debug.Log("called");
 
         }
         yield return new WaitForSeconds(0.1f);
       //snake and ladder check
       if(nodeList[routePosition].connectedNode!=null)
       {
         int conNodeId=nodeList[routePosition].connectedNode.nodeId;
         Vector3 nextPos=nodeList[routePosition].connectedNode.transform.position;

     }
