(WASD Top Down 3D) Movement animations relative to mouse direction.

When I am running forward and I point to the bottom of the screen the player points in that direction but the animation doesn’t switch to running backwards. Same for any other direction. I want my animations to be relative to the direction my mouse is pointing.

I have narrowed the problem down to what the script sends to the Animator component

What do I need to change for this to work?

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour
	public float speed = 6f;
	Vector3 movement;
	Animator anim;
	Rigidbody playerRigidbody;
	int floorMask;
	float camRayLength = 100f;

	void Awake ()
		floorMask = LayerMask.GetMask ("Floor");
		anim = GetComponent <Animator> ();
		playerRigidbody = GetComponent <Rigidbody> ();

	void FixedUpdate ()
		float h = Input.GetAxisRaw ("Horizontal");
		float v = Input.GetAxisRaw ("Vertical");
		Move (h, v);
		Turning ();
		Animating (h, v);

	void Move (float h, float v)
		movement.Set (h, 0f, v);
		movement = movement.normalized * speed * Time.deltaTime;
		playerRigidbody.MovePosition (transform.position + movement);

	void Turning ()
		Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);
		RaycastHit floorHit;
		if (Physics.Raycast (camRay, out floorHit, camRayLength, floorMask))
			Vector3 playerToMouse = floorHit.point - transform.position;
			playerToMouse.y = 0f;
			Quaternion newRotatation = Quaternion.LookRotation (playerToMouse);
			playerRigidbody.MoveRotation (newRotatation);

	void Animating (float h, float v)

am also wondering?
