Unity Engine

Hi, I’m new to unity. I’m trying to code for jumping but this doesn’t work. If anyone know what’s the problem please correct my code. Sorry if there is any mistake English isn’t my first language. Any advice would be appreciated!!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.XR.Interaction.Toolkit;

[RequireComponent(typeof(Rigidbody))]
public class PlayerControllerVR : MonoBehaviour
{
    [SerializeField] private InputActionReference jumpActionReference;
    [SerializeField] private float jumpForce = 500.0f;


    private XRRig _xrRig;
    private CapsuleCollider _collider;
    private Rigidbody _body;

    private bool IsGrounded => Physics.Raycast(
        new Vector2(transform.position.x, transform.position.y + 2.0f),
        Vector3.down, 2.0f);
    void Start()
    {

        _xrRig = GetComponent<XRRig>();
        _collider = GetComponent<CapsuleCollider>();
        _body = GetComponent<Rigidbody>();
        jumpActionReference.action. performed += OnJump;
    }

    // Update is called once per frame
    void Update()
    {
        var center = _xrRig.cameraInRigSpacePos;
        _collider.center = new Vector3(center.x, _collider.center.y, center.z);
        _collider.height = _xrRig.cameraInRigSpaceHeight;
    }

    private void OnJump(InputAction.CallbackContext obj)
    {
        if (!IsGrounded) return;
        _body.AddForce(Vector3.up * jumpForce);
    }
}

Add some Debug.Log, you should be able to find out where the problem lays (what part of code doesn’t work the way you think it does)
