Player behavior

This is attached to the Player object—it requires a Rigidbody and CapsuleCollider component, as follows:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerBehavior : MonoBehaviour 
{
    public float moveSpeed = 10f;
    public float rotateSpeed = 75f;
    public float jumpVelocity = 5f;
    public float distanceToGround = 0.1f;
    public LayerMask groundLayer;
    public GameObject bullet;
    public float bulletSpeed = 100f;

    public delegate void JumpingEvent(bool isGrounded);
    public event JumpingEvent playerJump;

    private float _vInput;
    private float _hInput;
    private Rigidbody _rb;
    private CapsuleCollider _col;
    private GameBehavior _gameManager;

    void Start()
    {
        _rb = GetComponent<Rigidbody>();
        _col = GetComponent<CapsuleCollider>();
        _gameManager = GameObject.Find("Game Manager").GetComponent<GameBehavior>();
    }

    void Update()
