RaycastHit.normal Problem

Hi,

I'm having a problem with RaycastHit.normal. I have the code below:

private var tGraphic : Transform;       //O Objeto que conter o grfico que exibir a seleo;
    var graphicOffset : Vector3;            //Deslocamento referente  largura do objeto tGraphic

    function Start(){
        tGraphic = GameObject.Find("Graphics").transform;
    }

    function FixedUpdate () {
        var hit:RaycastHit;
        var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        if(Physics.Raycast(ray, hit, 1000)){
            print(hit.normal);
            if(hit.transform.gameObject.name == "Ground"){
                var gridPosition = hit.point;
                gridPosition.x = Mathf.Ceil(gridPosition.x);
                gridPosition.z = Mathf.Ceil(gridPosition.z)-1;
                tGraphic.transform.position = gridPosition + graphicOffset;
                Debug.DrawLine(ray.origin, hit.point);
            }
        }
    }

I have a cube and I point the mouse to the cube's upper face, it returns the normal (0.0, 1.0, 0.0).

After this, I point to the front face, it return the normal (0.0, 0.0, 1.0)

Then, when I point to the upper face again, it still returning (0.0, 0.0, 1.0)

Please, can someone help me with this problem that seems to be simple?

I'm guessing it works fine and your Print is just giving confusing results.

For a different test, try: `Public var N : Vector3;` in global, use `N=hit.normal;` in your IF and take a look in the Inspector as you move around.
