Unity как исправить баг с прыжком?

 using UnityEngine; 
 
public class Player : MonoBehaviour  
{ 
    [SerializeField] private float moveSpeed = 1f; 
    [SerializeField] private float jumpForce = 4.3f; 
 
    private Rigidbody rb; 
    private bool isGrounded;

    private Vector3 movement; 
 
    private void Awake()

        input = new InputSystem_Actions(); 
        rb = GetComponent<Rigidbody>(); 
    } 
 
    private void OnEnable()  
    { 
        input.Enable(); 
    } 
 
    private void Update()  
    { 
        PlayerInput(); 
        if (input.Player.Jump.triggered && isGrounded) 
        { 
            Jump(); 
        } 
    } 
 
    private void FixedUpdate()  
    { 
        // Обновляем только горизонтальные компоненты скорости, оставляя вертикальную (y) без изменений. 
        Vector3 newVelocity = new Vector3(movement.x * moveSpeed, rb.velocity.y, movement.z * moveSpeed); 
        rb.velocity = newVelocity; 
    } 
 
    private void PlayerInput()  
    { 
        Vector2 inputVector = input.Player.Move.ReadValue<Vector2>(); 
        movement = new Vector3(inputVector.x, 0, inputVector.y); 
    } 
 
    private void Jump()  
    { 
        rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse); 
        isGrounded = false; 
    } 
 
    private void OnCollisionEnter(Collision collision)  
    { 
        if (collision.gameObject.CompareTag("Ground")) 
        { 
            isGrounded = true; 
        } 
    } 
}
