yo all!

Anyone know how to detect a finger press thats held down and sliding around the screen on an Android device? currently i can only detect a tap.

this is the code i have so far:

void Update () 
    {
        int nbTouches = Input.touchCount;

        if(nbTouches > 0)
        {
            for (int i = 0; i < nbTouches; i++)
            {
                Touch touch = Input.GetTouch(i);

                if(touch.phase == TouchPhase.Began)
                {
                    Ray screenRay = Camera.main.ScreenPointToRay(touch.position);

                    RaycastHit hit;
                    if (Physics.Raycast(screenRay, out hit))
                    {

                        if(hit.collider.tag == "Coin") { 
                            Destroy (hit.collider.gameObject);
                        }
                    }
                }

            }
        }
}

Have you searched for TouchPhase? You use one of them - TouchPhase.Began. It calls only once when you touch. There are a few more that will be useful for you. For example, TouchPhase.Moved. So you know that the touch has been moved (dragged). Hope it helps!
