hi, im using below script to add force to a ball, but it is adding force to X & Y axis only. Z is showing Zero. How to add force relative to swipe?
I’ve attached this script to main camera so that i can wsipe at any point please halp me to z direction.

using UnityEngine;
using System.Collections;

public class CameraScript : MonoBehaviour {

Vector3 mousestart, mouseend;
float starttime, endtime;
Vector3 force;
public GameObject ball;
Rigidbody rb;

// Use this for initialization
void Start () 
{
	rb = GetComponent<Rigidbody> ();
}

// Update is called once per frame
void Update () 
{
	if (Input.GetMouseButtonDown (0)) 
	{
		starttime = Time.time;
		mousestart = Input.mousePosition;
		
	}

	if (Input.GetMouseButtonUp (0)) 
	{
		endtime = Time.time;
		mouseend = Input.mousePosition;

		float totaltime = endtime - starttime;
		Vector3 distance = mouseend - mousestart;

		force = (distance/totaltime);
		Debug.Log(distance.z);
		ball.rigidbody.AddForce(force);
	}

}

}

Vector3 distance.z = (mouseend - mousestart).magnitude;
