Touch Input help..

Question

I recently published my game, but it turns out that the stars aren't being destroyed with a simple touch. But the GUI buttons are working fine.

Here is my script:

 function Update () {
 
      if (Input.GetMouseButtonDown(0))
      {
  
        var hitm : RaycastHit2D = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
        if(hitm.collider != null)
        {
        audio.Play();
        GameMaster.currentScore += 1;
          Destroy (hitm.collider.gameObject);
        }
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began){
        if(hitm.collider != null)
        { 
          Destroy (hitm.collider.gameObject);
        }
      }
 }
 }

I was told to refer to this: http://docs.unity3d.com/ScriptReference/Input.GetTouch.html ,but I have no clue how to edit it.

Here is my game if you want to test it out. https://play.google.com/store/apps/details?id=com.ZYPHER.TapTheStars

Why are you using? Old debugging line?

 if (Input.GetMouseButtonDown(0))

Seems like this if-statement should be removed if this is a game for android.

What should it be replaced with?

Try something like this:

 function Update () {
      if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
      {
  
        var hitm : RaycastHit2D = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position), Vector2.zero);
        if(hitm.collider != null)
        {
        audio.Play();
        Game$$anonymous$$aster.currentScore += 1;
          Destroy (hitm.collider.gameObject);
        }
      }
 }
 }

Have not tried the code, so not 100% sure that all the syntax is right. This script will, if the user taps the screen, see if the user touches a gameobject with a collider. If that is true, a sound will play, 1 will be added to currentScore and the gameobject with a collider will get destroyed. Hopefully this makes sense :)
