Game Development How to Make a Video Game Player Input and Cameras Move the Player with Animation

The variable playerAnimator of PlayerMovement has not been assigned?


using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

    private Animator playerAnimator;
    private float moveHorizontol;
    private float moveVertical;
    private Vector3 movement;

    // Use this for initialization
    void Start () {

        playerAnimator = GetComponent<Animator> ();


    // Update is called once per frame
    void Update () {

        moveHorizontol = Input.GetAxisRaw ("Horizontal");
        moveVertical = Input.GetAxisRaw ("Vertical");

        movement = new Vector3 (moveHorizontol, 0.0f, moveVertical);


    void FixedUpdate ()
        if (movement != Vector3.zero) {
            playerAnimator.SetFloat ("Speed", 3f);
        } else {
            playerAnimator.SetFloat ("Speed", 0f);


I'm not exactly sure how to fix this and do not see anything I did wrong? But I can still run my game and when I press W the frog does move forward.
