Question by Yukken · Nov 02, 2017 at 06:26 AM · nullreferenceexception transform.position transform.rotation

object referance not set to instance of an object when accessing transform.position

I'm trying to rotate a sprite according to mouse position.But I get an error when I hit play. I'm using transform.position to get the position of the object this script is attached to but I get an error.

I'm using the latest version of unity 5.6.

The code:

using System.Collections; using System.Collections.Generic; using UnityEngine; [RequireComponent (typeof (playerController))]

public class controllcenter : MonoBehaviour {

 public float moveSpeed = 5f;
 playerController controller;
 // Use this for initialization
 void Start () {
     controller = GetComponent<playerController>();    
 }
 
 // Update is called once per frame
 void Update () {
     Vector3 difference = (Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position).normalized;
     float angle = Mathf.Atan2(difference.y,difference.x)*Mathf.Rad2Deg;
     transform.rotation = Quaternion.Euler(0, 0, angle);

     Vector2 playerInput = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));
     Vector2 moveVelocity = playerInput.normalized * moveSpeed;
     controller.updateVelocity(moveVelocity);
 }
