My frog only moves forward, help!

using UnityEngine;
using System.Collections;

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 ("Vertical");

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

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

Thats my code, please help.

I recommend to downolad Nick code and paste line by line and see if it works. I would help but i dont know about the code so what you could do its just copy and paste Nick code and see if it works, and then if it does, go line by line comparing it, ud know something is wrong then.

Hi Jules, I think you are doing ok so far - the left/right rotations are covered a few videos later on in the course.

Unless you didnt do the rotation of other directions with Nick :D Usualy everything you do in porgramming, you need to say it step by step.

So every single thing that you want to happen, you need to say , so if you did forward, you need to do jump, left, right, backwards and all.

Hope this helps too.

Hi juleshanson,

You are missing the "Quaternion" code; quaternion is a mathematical algorithm used to rotate 3D objects. The process of rotating 3D objects is really easy using Unity's Quaternion class (i.e. really easy, once you understand how to use this class! ;-) ). NOTE: You do not want to write your own code to rotate a 3D object!

Under "Player Input and Cameras", start at the "Quaternions" training video.

<Hint> You're FixedUpdate() method is where the Quaternion code will be added.
