Question Offset Vector2 by another Vector2

Code (CSharp):

1. if(touch.phase == TouchPhase.Moved)
2.             {
3.                 if(IsHoldingPlayer)
4.                 {
5.                     transform.position = new Vector2(transform.position.x, TouchPos.y);
6.                 }
7.             }

using this code I want to make it so my player moves up and down based off the finger position, but as of now they just teleport to the finger. How do I make it so if the user is touching the top of the screen, and the player is at the bottom, the user can still move the character up and down without teleporting to the finger?

 

this code is in the update function by the way

 

Two possible approaches with completely different outcomes:

- treat input as a movement, then update the position each frame based on the movement

OR

- use this approach:

Smoothing movement between any two particular values:

You have currentQuantity and desiredQuantity.
- only set desiredQuantity
- the code always moves currentQuantity towards desiredQuantity
- read currentQuantity for the smoothed value

Works for floats, Vectors, Colors, Quaternions, anything continuous or lerp-able.
