COOLCODER

My sprite is not changing when i press space bar and jump.

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class Playercontrols : MonoBehaviour

{

  private float leftdirection;

  private float xdirection;

  Rigidbody2D Rb;

  float grounddistance = 0.4f;

  bool isGrounded ;

  public LayerMask ground;

  public Transform groundchecktrans;

  

  public Sprite jump;

  public Sprite idle;

  void Start()

  {

     

    Rb = GetComponent<Rigidbody2D>();

     

  }

  // Update is called once per frame

  void Update()

  {

    isGrounded = Physics2D.OverlapCircle(groundchecktrans.position, grounddistance, ground);

    xdirection = Input.GetAxis("Horizontal");

     

    if (Input.GetKey(KeyCode.D))

    {

      Rb.velocity = new Vector2(10, Rb.velocity.y);

    }

     

    if (Input.GetKey(KeyCode.A))

    {

      Rb.velocity = new Vector2(-10, Rb.velocity.y);

      this.gameObject.GetComponent<SpriteRenderer>().sprite = idle;

    }

    

    if (Input.GetKeyDown(KeyCode.Space) && isGrounded == true)

    {

       

      Rb.velocity = new Vector2(Rb.velocity.x,10);

      this.gameObject.GetComponent<SpriteRenderer>().sprite = jump;

    }
