Question by FreeReignPublishing · Jun 03, 2018 at 09:18 PM · c#touch line renderer

Problem solving. The line renderer does not follow touch as accurate as the mouse input. Not sure why?

I tested both mouse and touch and here's the code

     public float width;
     public Color color = Color.red;
     private LineRenderer lr;
     private Vector3[] linePoints = new Vector3[2];
     public float speed;
     private Vector3 lastpos;
     private Vector3 fingerPos;
     public bool mouseControl;
 
     void Start()
     {
         lr = GetComponent<LineRenderer>();
         if (!lr) lr = gameObject.AddComponent<LineRenderer>();
         lr.material.color = color;
         lr.widthMultiplier = width;
         linePoints[0] = Vector3.zero;
         lr.positionCount = linePoints.Length;
         lastpos = transform.position;
         fingerPos = transform.position;
     }
 
     void Update()
     {
         if (lr.enabled == false)
         {
             //mouse
             if (mouseControl == true) 
             {
                 transform.position = Vector3.MoveTowards(transform.position, lastpos, speed * Time.deltaTime);
             }
 
             //touch
             if (mouseControl == false)
             {
                 transform.position = Vector3.MoveTowards(transform.position, fingerPos, speed * Time.deltaTime);
             }
         }
 
         if (Input.GetMouseButton(0) || Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Stationary)
         {
             if (lr.enabled == false) lr.enabled = true; 
 
             //mouse
             if (mouseControl == true) 
             {
                 Camera c = Camera.main;
                 Vector3 p = c.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, c.nearClipPlane));
                 linePoints[1] = p;
                 lr.SetPositions(linePoints);
             } 
 
             //touch
             if (mouseControl == false) 
             {
                 Touch touch = Input.GetTouch(0);
                 Camera c = Camera.main;
                 Vector3 p = c.ScreenToWorldPoint(new Vector3(Input.GetTouch(0).position.x, Input.GetTouch(0).position.y, c.nearClipPlane));
                 linePoints[1] = p;
                 lr.SetPositions(linePoints);
             }
         }
         else if (Input.GetMouseButtonUp(0) || Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended)
         {        
             lr.enabled = false;
 
             //mouse
             if (mouseControl == true) 
             {
                 lastpos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                 lastpos.z = transform.position.z;
             }   
 
             //touch
             if (mouseControl == false)
             {
                 fingerPos = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
                 fingerPos.z = transform.position.z;
             }     
         }
     }`
