So, I got this to do the anims for my sprite in Unity 2d...

using UnityEngine;
using System.Collections;

public class Move : MonoBehaviour {
public float Speed = 2;
Animator anim;
// Use this for initialization
void Start () {
    anim = GetComponent<Animator>();
}

void FixedUpdate () {
    rigidbody2D.velocity = new Vector2(Input.GetAxis("Horizontal") * Speed, 0);
    anim.SetFloat("HorizontalSpeed", Mathf.Abs(rigidbody2D.velocity.x));

if(transform.localScale.x > 0 && rigidbody2D.velocity.x  < 0)
    transform.localScale = new Vector3(-1, 1, 1); 

if(transform.localScale.x < 0 && rigidbody2D.velocity.x > 0)
    transform.localScale = new Vector3(1, 1, 1); 

}
}

That works fine... then I add the script so he can move up and down. (the previous was moving left+right)

using UnityEngine;
using System.Collections;

public class UpMove : MonoBehaviour {
public float VerticalSpeed = 2;
Animator anim;
// Use this for initialization
void Start () {
    anim = GetComponent<Animator>();
}

void FixedUpdate () {
    rigidbody2D.velocity = new Vector2(Input.GetAxis("Vertical") * VerticalSpeed, 0);
    anim.SetFloat("VerticalSpeed", Mathf.Abs(rigidbody2D.velocity.y));
}
}

Welll.. The second script doesn't do anything.

Welll.. The second script doesn't do anything. I've been working at this (rookie noobness) for around an hour now.. so pls pls pls.
