Input.GetTouch is zero based, so the first one is Input.GetTouch(0), Input.GetTouch(1) would refer to the second touch.
i pretty much did, you are trying to access the wrong NU$$anonymous$$BER based off GetTouch method being zero based. You confirmed there was just 1 Touch with the line:
if (Input.touchCount == 1){
but just after that you checked for the second touch by:
var touchOne = Input.GetTouch(1);
it should be:
var touchOne = Input.GetTouch(0);
because the first touch in the array/collection is actually access by 0. This is displayed in the documentation for Input.GetTouch and it's examples
