Sluggish relative drag

Questions & Answers
1

I am trying to move my player based on relative drag . Here is my script :

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;

public class playerInput : MonoBehaviour , IPointerDownHandler,IDragHandler,IPointerUpHandler
{
	private Vector3 startPos;
	private Vector3 curPos;
	GameObject player;


	void Start(){

		player = GameObject.FindWithTag ("Player");

	}

	void Update()
	{
		
	}



	#region IPointerDownHandler implementation
	public void OnPointerDown (PointerEventData eventData)
	{
		startPos = Camera.main.ScreenToWorldPoint (eventData.position);
	}
	#endregion

	#region IDragHandler implementation

	public void OnDrag (PointerEventData eventData)
	{
		curPos = Camera.main.ScreenToWorldPoint (eventData.position) - startPos;
		player.transform.position = (player.transform.position + curPos)/2;
	}

	#endregion


	#region IPointerUpHandler implementation
	public void OnPointerUp (PointerEventData eventData)
	{
	}
	#endregion
}

It works fine , but during initial drag it snaps to off location , after that the movement is responsive and nice . If i do

player.transform.position += curPos/40;

instead of

player.transform.position = (player.transform.position + curPos)/2;

Then it wont snap and will fine , will move relative to my finger etc but the movement is sluggish and slow . If i dont divide curPos by 40 then the character moves too fast . Not sure what to do , any help is appreciated .

I got relative drag to work ( this is sort of hacky way i guess but it works fine ) . What it does is , it lets u move the object based on relative drag, you do by moving your finger somwhere on the screen ( like in the game " Shooty skies ") .

using UnityEngine;
using System.Collections;

public class drag : MonoBehaviour
{

	public GameObject player;
	GameObject mainBody;
	Vector3 tempPos;

	void Start(){
		player = GameObject.FindWithTag ("Player");
		mainBody = player.transform.GetChild (0).gameObject;
	}

	void Update(){
		if (Input.touchCount == 1 && Time.timeScale > 0.0f) {

			foreach (Touch touch in Input.touches) {

				if (touch.phase == TouchPhase.Began) {
					tempPos = player.transform.position;
					player.transform.position = Camera.main.ScreenToWorldPoint (Input.mousePosition);
					player.transform.position = new Vector3 (player.transform.position.x, 0, player.transform.position.z);
					mainBody.transform.position = tempPos;
				}

				if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled) {
					player.transform.position = Camera.main.ScreenToWorldPoint (Input.mousePosition);
					player.transform.position = new Vector3 (player.transform.position.x, 0, player.transform.position.z);
				}

				else if (touch.phase == TouchPhase.Ended || touch.phase == TouchPhase.Canceled) {
					tempPos = mainBody.transform.position;
					player.transform.position = tempPos;
					mainBody.transform.position = player.transform.position;
				}

			}
		}
	}
}
