Hello,
I have a problem with Space Shooter turtorial. I have no error untill i start the game and enemy needs to dodge. Under the turtorial i can see the script even copy pasted it and still nothing :/.
NullReferenceException: Object reference not set to an instance of an object
EvasiveManeuver.FixedUpdate () (at Assets/_script/EvasiveManeuver.cs:42)
public float dodge;
public float smoothing;
public float tilt;
public Vector2 startWait;
public Vector2 maneuverTime;
public Vector2 maneuverWait;
public Boundary boundary;
private float currentSpeed;
private float targetManeuver;
private Rigidbody rb;
void Start ()
{
currentSpeed = rb.velocity.z;
rb = GetComponent ();
StartCoroutine (Evade ());
}
IEnumerator Evade()
{
yield return new WaitForSeconds (Random.Range (startWait.x, startWait.y));
while (true)
{
targetManeuver = Random.Range (1, dodge) * -Mathf.Sign (transform.position.x);
yield return new WaitForSeconds (Random.Range (maneuverTime.x, maneuverTime.y));
targetManeuver = 0;
yield return new WaitForSeconds (Random.Range (maneuverWait.x, maneuverWait.y));
}
}
void FixedUpdate ()
{
float newManeuver = Mathf.MoveTowards (rb.velocity.x, targetManeuver, Time.deltaTime * smoothing);
rb.velocity = new Vector3 (newManeuver, 0.0f, currentSpeed);
rb.position = new Vector3
(
Mathf.Clamp (rb.position.x, boundary.xMin, boundary.xMax),
0.0f,
Mathf.Clamp (rb.position.z, boundary.zMin, boundary.zMax)
);
rb.rotation = Quaternion.Euler (0.0f, 0.0f, rb.velocity.x * -tilt);
}
