Touch movement not working

I am trying to move a gameObject by touch.

    #pragma strict

var player : GameObject;
var moveToPos : Vector3;
var touchPos : Vector3;
var myTransform : Transform;
var moveSpeed : int;

function start ()
{
   myTransform = transform;
}

function Update ()
{
   touchPos = Input.mousePosition;

   player.transform.position.z = 5;
      
   if (Input.GetMouseButton(0)) {
   
   moveToPos = Vector3 (touchPos.x , myTransform.position.y , 5);   

   myTransform.Translate(moveToPos * moveSpeed * Time.deltaTime);
   
   Debug.Log(touchPos);

}
}

But no matter where I touch the object zooms to the right. I have asked someone with more experienced than me in unity and he has no idea why it isn’t working. I also noticed that i had to set all the variable’s values manually in the inspector.

Input.mousePosition returns ScreenCoordinates in pixels. Those are always > 0. So the x value of your velocity vector (the one you use to translate) will always be > 0 hence you move to the right.

What you have to do is convert the ScreenCoordinates to WorldCoordinates. You can do that using Camera.ScreenToWorldPoint.
