NullReference. Need Help.

[Ashton-Benedict]

I am using a variable from another script (facingRight). I get the error NullReferenceException, and I cant figure out what exactly I need to reference.

public class BulletTrail : MonoBehaviour {

    public int moveSpeed = 0;

    private PlayerController playerController;

    void Awake()
    {
        playerController = transform.root.GetComponent<PlayerController>();
    }

    void Update()
    {
            if (!playerController.facingRight)
            {
                transform.Translate(Vector3.left * Time.deltaTime * moveSpeed);
                Destroy(gameObject, 1);
            }
            if (playerController.facingRight)
            {
                transform.Translate(Vector3.right * Time.deltaTime * moveSpeed);
                Destroy(gameObject, 1);
            }
    }
}

I’m guessing playerController is failing to get the component, which throws the error when you try to use it.

 void Awake()
 {
     playerController = transform.root.GetComponent<PlayerController>();
 }

^ This, are you sure this is working? Verify with a Debug.Log:

Debug.Log("is playerController null? " + (playerController == null));

Make adjustments so playerController is not null.
