cant trigger animation while jump

hi im trying make shot animation while jumping, the animation in ground is good. The problem is animation cant triggered when "player" in the air and the shot animation triggered after player touching ground.

this my controller:

and my code:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerController : MonoBehaviour {
     //speed move
     public float Speed;
 
     //jump var
     bool grounded = false;
     float groundcheckradius = 0.2f;
     public LayerMask groundlayer;
     public Transform groundCheck;
     public float jumpheight;
 
 
     Rigidbody2D myRB;
     Animator myAnim;
     bool facingRight;
 
     //shooooottttt
     public Transform fromwhere;
     public GameObject bullet;
     float firerate = 0.5f;
     float nextfire = 0f;
 
 
     void Start ()
     {
         myRB = GetComponent<Rigidbody2D>();
         myAnim = GetComponent<Animator>();
 
         facingRight = true;
     }
     
     // Update is called once per frame
 
     void Update()
     { 
         if(grounded && Input.GetAxis("Jump")>0)
         {
             grounded = false;
             myAnim.SetBool("isGrounded", grounded);
             myRB.AddForce(new Vector2(0,jumpheight));
         }
 
         //shot
         if (Input.GetAxis("Fire1") > 0)
         {
 
             shot();
             
         }
     }
     void FixedUpdate ()
     {
         //check if riki are grounded
         grounded = Physics2D.OverlapCircle(groundCheck.position, groundcheckradius, groundlayer);
         myAnim.SetBool("isGrounded", grounded);
 
         myAnim.SetFloat("verticalSpeed", myRB.velocity.y);
 
 
         float move = Input.GetAxis("Horizontal");
         myAnim.SetFloat("speed", Mathf.Abs(move));
 
         myRB.velocity = new Vector2(move*Speed, myRB.velocity.y);
 
         flip(move);
     }
 
     void flip(float move)
     {
         if (move > 0 && !facingRight || move < 0 && facingRight)
         {
             facingRight = !facingRight;
             Vector3 theScale = transform.localScale;
             theScale.x *= -1;
             transform.localScale = theScale;
         }
 
     }
 
     void shot()
     {
         if (Time.time > nextfire)
         {
             nextfire = Time.time + firerate;
             myAnim.SetTrigger("triggershot");
             if (facingRight)
             {
                 Instantiate(bullet, fromwhere.position, Quaternion.Euler(new Vector3(0, 0, 0)));
             }
             else if (!facingRight)
             {
                 Instantiate(bullet, fromwhere.position, Quaternion.Euler(new Vector3(0, 0, 180f)));
             }
             {
 
             }
         }
     }
 }
 

thanks for your help ^^
