Rhythm Game - When I touch an object with mobile in only activates 80% of the time...

Question

Hello, -

I am using android. -

I have a rhythm game where notes fall. This script it attached to the notes so that when you touch them on mobile they disappear. It works well but sometimes it doesn't work.. I touch them but they do not go to the blank sprite and I have no idea why..

I have 2 touches registered below as there is sometimes 2 that spawn at ones so you need to touch them both. Without the second section of code it would only let me press one at once.

 void Update()

{

 foreach (Touch touch in Input.touches)
     {
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
     {
         touchPosWorld = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
         touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y);
         RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward);

         if (hitInformation.collider.tag != "Button")
         {
             touchedObject = hitInformation.transform.gameObject;
             touchedObject.GetComponent<SpriteRenderer>().sprite = blank;
         }
     }

     if (Input.touchCount > 0 && Input.GetTouch(1).phase == TouchPhase.Began)
     {
         touchPosWorld1 = Camera.main.ScreenToWorldPoint(Input.GetTouch(1).position);
         touchPosWorld2D2 = new Vector2(touchPosWorld1.x, touchPosWorld1.y);
         RaycastHit2D hitInformation2 = Physics2D.Raycast(touchPosWorld2D2, Camera.main.transform.forward);

         if (hitInformation2.collider.tag != "Button")
         {
             touchedObject1 = hitInformation2.transform.gameObject;
             touchedObject1.GetComponent<SpriteRenderer>().sprite = blank;
         }
     }
 }    
 }

I hope you can help.

Thank you very much.

Hello, You can try this :

  void Update()
         {
             if (Input.touchCount > 0)
             {
                 for (int i = 0; i < Input.touchCount; i++)
                 {
                     Touch touch = Input.GetTouch(i);
                     if (touch.phase == TouchPhase.Began)
                     {
                        Ray ray = Camera.main.ScreenPointToRay(touch.position);
                        RaycastHit2D hitInformation = Physics2D.Raycast(ray.origin, ray.direction);
     
                         if (hitInformation.collider.tag != "Button")
                         {
                             GameObject touchedObject = hitInformation.transform.gameObject;
                             touchedObject.GetComponent<SpriteRenderer>().sprite = blank;
                             Instantiate(partRed, touchedObject.transform.position, Quaternion.identity);
                             partRed.Play();
                         }
                     }
                 }
             }
     
         }

That will test all touches and make a ray directly by the camera.

Thank you for your reply and your help. Unfortunately I replaced the script on the 'notes' with your script and still have the problem of some not disappearing when touched.. :(

Do you have any other thoughts?

Thanks again
