Play animation when mouse drag

Hi!

Is the first time that I’m using Unity, and I’m having some issues. I have a 3D object animated in Cinema 4D that I imported to Unity. I need to play the animation of this object when I click and drag my mouse up, and rewind it when I click and drag the mouse down. What 3# script can I use to do it?

Thank you

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
  public Animator anim;

  void Update ()
  {
    if (input.GetKeyDown("Mouse0") && input.GetAxis("MouseY") > 0)
    {
      anim. SetTrigger("forwardAnimation");
    }
    if (input.GetKeyDown("Mouse0") && input.GetAxis("MouseY") < 0)
    {
      anim. SetTrigger("backwardsAnimation");
    }
  }
}
