Question by LenaDoll · Jul 25, 2017 at 02:16 PM · valuecounternull reference exceptionclones

How can I avoid null point exception and count clones? My counter only counts the original ball but not the clones. Help?

[CODE]

 public int count;
     public Text countText;
 // Use this for initialization
 void Start () {
     count = 0;
     SetCountText ();
     Destroy (this.gameObject, 10);
 }
 
 // Update is called once per frame
 void Update () {
     
 }

 void OnMouseDown() {
     if(Input.GetMouseButton (0))
     {
         count += 1;
         SetCountText ();
         Destroy (this.gameObject);
     }
 }

 void SetCountText(){
     if (countText != null)
     {
         countText.text = "" + count.ToString();
     }
 }


} [\CODE]

Simplest, most naive way:

 public int static count = 0;
 public Text countText;
 
  // Use this for initialization
  void Start () 
 {
      SetCountText ();
      Destroy (this.gameObject, 10);
  }

Are you sure your Text reference is being preserved across the clones?

Here would be the next step in naive solutions. $$anonymous$$ake sure the first one has its text reference:

 public static int count = 0;
 public Text countText;
 public static Text staticCountText;
 
 // Use this for initialization
 void Start () {
 
     if (countText != null)
         staticCountText = countText;
 
     SetCountText ();
     Destroy (this.gameObject, 10);
 }
 
 void SetCountText(){
     if (staticCountText != null)
     {
         staticCountText.text = "" + count.ToString();
     }
 }
