If I can’t declare it as a statement should I just wait until I need to use it? It’s a very simple question ,but I need to know if I[m going about this the right way. How could I store hit.normal in a variable?

Here’s the script:

using UnityEngine;
using System.Collections;

//
//THIS SCRIPT CONTROLS THE MOVEMENT OF THE PLAYER 
//
[RequireComponent (typeof (Rigidbody))]
public class PlayerMovement : MonoBehaviour 
{
	//ALL OF THE PUBLIC VARIABLES
	public float walkSpeed = 6.0f;
	public float runSpeed = 12.0f;
	public float jumpSpeed = 8.0f;

	//ALL OF THE PRIVATE VARIABLES
	private Vector3 moveDirection;
	private float speed;

	void Start () 
	{
		speed = walkSpeed;
	}
	void Update () 
	{
		moveDirection = new Vector3 (Input.GetAxisRaw ("Horizontal"),0, Input.GetAxisRaw ("Vertical")).normalized;

		RaycastHit hit;
		Physics.Raycast (transform.position, -Vector3.up, out hit);

		if (Physics.Raycast (transform.position, -Vector3.up, out hit))
		{
			hit.normal;
		}
	}
	void FixedUpdate()
	{
		rigidbody.MovePosition (rigidbody.position + transform.TransformDirection(moveDirection) * speed * Time.deltaTime);
	}
}

“How could I store hit.normal in a variable?”

Vector3 hitNormalSavedInAVariable;
hitNormalSavedInAVariable = hit.normal;
