title: Unity C# - Rigidbody.AddForce not working as intended
body: <p>So, I am trying to make a cube move with the WSAD buttons and for some reason, even though I am not touching any buttons, it moves diagonally up and to the left. I am using Unity 4.5.1</p>
  
  <p>Code:</p>
  
  <pre><code>using UnityEngine;
  using System.Collections;
  
  public class Movement : MonoBehaviour {
      public float moveSpeed;
      private Vector3 input;
  
      // Use this for initialization
      void Start () {
      }
  
      // Update is called once per frame
      void Update () {
          input = new Vector3(Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
          print(input); 
      }
  }
  </code></pre>
