NullReferenceException: Object reference not set to an instance of an object NewBehaviourScript.Update () (at Assets/Scripts/NewBehaviourScript.js:33)
I'm trying to do a Drag and Drop object but Unity give me this error:
NullReferenceException: Object reference not set to an instance of an object NewBehaviourScript.Update () (at Assets/Scripts/NewBehaviourScript.js:33)

Did you attach this to the camera? My drag and drop(for 2d, 5 touches Max) looks like this:
RaycastHit2D[] hit = new RaycastHit2D[5];
GameObject[] hits = new GameObject[5];
void Update ()
{
if(Input.touchCount > 0)
{
foreach(Touch t in Input.touches)
{
if(Input.GetTouch(t.fingerId).phase == TouchPhase.Began)
hit[t.fingerId] = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.GetTouch(t.fingerId).position), Vector2.zero);
if(hit[t.fingerId].collider.name == "Tri(Clone)" && Input.GetTouch(t.fingerId).phase == TouchPhase.Moved)
{
hits[t.fingerId] = hit[t.fingerId].transform.gameObject;
hits[t.fingerId].transform.position = new Vector3(Camera.main.ScreenToWorldPoint(Input.GetTouch(t.fingerId).position).x,Camera.main.ScreenToWorldPoint(Input.GetTouch(t.fingerId).position).y,0f);
}
}
}
}
}
