how to offset finger touch ?

Question

Hi : my object falow my finger very well but it teleport where ever i touch and i want it to move the object with offset distance between the object and the finger. and of course the offset distance should be variant if i lifted my finger and touched the screen in different position again. her is my code :

  void finger()
  {
      
   if(Input.touchCount > 0)
        {
    Vector3 pl = new Vector3(Input.GetTouch(0).position.x,halfH,10);
    transform.position = Camera.main.ScreenToWorldPoint (pl);
                         
        }
    
   }

Answer 1

finally problem solved ! by this code and moving the camera 3 points to the right so i don't get negative numbers when i touch the left half of the screen because if camera at zero position and the camera size is 5 then i will get -2.5 to the left and 2.5 to the right. and it's mater because of the offset calculation below and it's hard to explain every thing i had to add texts to the screen the touch position & the transform position & the offset distance to understand every thing but now any one can use this script

  if (Input.touchCount > 0) 
             {
                 // converting the touch position from ScreenSpace To WorldPoint
                 Vector3 tpos = Input.GetTouch (0).position;
                 Vector3 pos = Camera.main.ScreenToWorldPoint (tpos);

                  // i is a float variable 
                  i = pos.x; // geting only the X position of touch
 
                    // setting the offset distance only when touch began
                     if(Input.GetTouch(0).phase == TouchPhase.Began)
                     {
                         // offset is a float variable 
                         offset = transform.position.x - i;
                     }
     
                     if(Input.GetTouch(0).phase == TouchPhase.Moved)
                     {
                         transform.position = new Vector2(i+offset,-3);
                     }
     
                 }
             }
