C# code throwing error for FrognLog tutorial.

Hey all,

I'm new and have never worked in C#. I'm as far as adding as a playerMovement script to my player(Frong). But when I press play it throws 2 errors saying:

!(in a yellow triangle) Parameter 'speed' does not exist. UnityEngine.Animator:SetFloat(String, Single) and !(in red stop sign) ArgumentException: Input Axis vertical is not set up.

To Change the input settings use: Edit -> Project Settings -> Input

My code is:

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

public class PlayerMovement : MonoBehaviour {

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

// Use this for initialization
void Start() {
    playerAnimator = GetComponent<Animator>();


// Update is called once per frame
void Update() {
    moveHorizontal = Input.GetAxisRaw ("Horizontal");
    moveVertical = Input.GetAxisRaw ("vertial");

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

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



The Frog is a prefab that I downloaded and I'm editing it for this tutorial. The code written matches the tutorial video. I'm just not sure what and how i should fix this issue. Do I add another Component to the player which triggers Vertical axis?

The name of axis are case-sensitive. That means you must not forget the capital letter at the beginning.

YES! Ok i'll keep an eye out for that! Thanks for the heads up Samuel!

No problem. And thank you for replying, very few people do so and it's a good feeling, even on small, easy answers like this one.
