I am using this script to rotate the gun using mouse pointer,
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Weapon : MonoBehaviour
{
public float offset;
private void Update()
{
Vector3 difference = Camera.main.ScreenToViewportPoint(Input.mousePosition) - transform.position;
float rotZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rotZ + offset);
}
}
but in unity it showing an error,
NullReferenceException: Object reference not set to an instance of an object
Weapon.Update () (at Assets/Scripts/Weapon.cs:11)
