Mobile touch for my rhythm game not 100% working. Not all note are touchable..

Unity Engine

Good day,

I am in the process of making a rhythm game. My first time trying touch capability in one of my games. Basically when the ‘notes’ spawn and I touch them some of them don’t register as hit even though I 100% hit them.

I tired counting to see if it every x note didn’t work but that wasn’t the case.

  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);
                 Vector2 touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y);
                 RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward);
                 if (hitInformation.collider.tag != "Button")
                 {
                     GameObject touchedObject = hitInformation.transform.gameObject;
                     touchedObject.GetComponent<SpriteRenderer>().sprite = blank;
                     Instantiate(partRed, touchedObject.transform.position, Quaternion.identity);
                     partRed.Play();
                 }
                 }
             }

**// 2nd touch..**
         if (Input.touchCount > 0 && Input.GetTouch(1).phase == TouchPhase.Began)
         {
             touchPosWorld = Camera.main.ScreenToWorldPoint(Input.GetTouch(1).position);
             Vector2 touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y);
             RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward);
             if (hitInformation.collider.tag != "Button")
             {
                 GameObject touchedObject1 = hitInformation.transform.gameObject;
                 touchedObject1.GetComponent<SpriteRenderer>().sprite = blank;
                 Instantiate(partRed, touchedObject1.transform.position, Quaternion.identity);
                 partRed.Play();
             }
             }

**// 3rd touch..**
         if (Input.touchCount > 0 && Input.GetTouch(2).phase == TouchPhase.Began)
         {
             touchPosWorld = Camera.main.ScreenToWorldPoint(Input.GetTouch(1).position);
             Vector2 touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y);
             RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward);
             if (hitInformation.collider.tag != "Button")
             {
                 GameObject touchedObject2 = hitInformation.transform.gameObject;
                 touchedObject2.GetComponent<SpriteRenderer>().sprite = blank;
                 Instantiate(partRed, touchedObject2.transform.position, Quaternion.identity);
                 partRed.Play();
             }
         }
     }

The particles don’t won’t either but I posted that into another question on this board ;).

Thanks for your help.

Maybe 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.
