Very simple hover script. Use in conjunction with WASD controller handling planar movement.
using UnityEngine;
public class Hover : MonoBehaviour
public float maxDistance, maxForce;
private Vector3 forceVector;
void FixedUpdate ()
RaycastHit hit;
if (Physics.Raycast (transform.position, -Vector3.up, hit))
if (hit.distance < maxDistance)
forceVector = Vector3.up * ((maxDistance - hit.distance) / maxDistance) * maxForce;
rigidbody.AddForce (forceVector);
void OnGUI ()
GUILayout.Label (forceVector.ToString ());
