NullReferenceException in Raycast script

Questions & Answers
1

So, I’ve come up with a script that tells me what I’m looking at and then makes me move toward it when I hold the “Fire1” button. However when I press this button it gives me a NullReferenceException. I can’t seem to locate the problem.

The script still works but I would like “not” to get the error report.

I have tried to locate the problem but my brain is failing me it seems.
And help would be appreciated!

   private var distance : float = 20.0;



var speed : float;

var moveToMe : Transform;





function Update () {



    var cam : Transform = Camera.main.transform;

	var ray = new Ray(cam.position, cam.forward);

    var hit : RaycastHit;

    

    if(Physics.Raycast(ray, hit, distance)){

    

    var moveToMe = hit.transform;

    Debug.Log(hit.transform.name);

    }

    

    if (Input.GetButton("Fire1") && hit.collider.tag == "Lerpz"){

     	

    transform.position = Vector3.Lerp(transform.position, moveToMe.position, Time.deltaTime * speed);

    }

    

    Debug.DrawLine(ray.origin, ray.origin + ray.direction * distance);

    

}

Your problem is that the if(Input.GetButton("Fire1")... isn’t inside the if that checks whether the Raycast hit something - so it happens even if it doesn’t. Make it like this:

if(Physics.Raycast(ray, hit, distance)){



    var moveToMe = hit.transform;

    Debug.Log(hit.transform.name);

    



    if (Input.GetButton("Fire1") && hit.collider.tag == "Lerpz"){



    transform.position = Vector3.Lerp(transform.position, moveToMe.position, Time.deltaTime * speed);

    }
}
