}

function Update() { if(Input.GetMouseButtonDown(0)) { Shoot(); } }

function Shoot() { var bullet : GameObject = Instantiate(bulletPrefab , transform.Find("projRelease").transform.position ,Quaternion.identity); //ejectSound.Play(); bullet.rigidbody.AddForce(transform.forward * 1000); }

Looks like Transform.Find is returning null, which you then try to access with ".transform.position". See Jessy's answer for more details in your situation, but general it is good practice to check the return value from a function rather than reference it directly. Good luck!

Transform.Find can only return transforms that are children of whatever Transform you are referencing. projRelease is not the name of a child of the game object to which this script is attached. Maybe you meant to use GameObject.Find? That's what I'd assume; why else would you have used .transform.position, considering Transform.Find already returns a Transform?
