enemy projectiles
I am using an enemy projectile script that works fine until the player is killed. After the player is killed the red flag error "Null Reference Exception: Object reference not set to an instance of an object Enemy Star Controller .Start () (at Assets/Scripts/Enemy Star Controller.cs:28)" appears. The script is for a 2D platformer game. (more below)
Line 28 of the script is highlighted when I click on the error code however I do not know how to fix it and the code compiles without any problems. The Enemy Star Controller script is below any help will be greatly appreciated.
1 using UnityEngine;
2 using System.Collections;
3
4 public class EnemyStarController : MonoBehaviour {
5.
6 public float speed;
7
8 public PlayerController player;
9
10 //public GameObject enemyDeathEffect;
11
12 public GameObject impactEffect;
13
14 //public int points to kill;
15
16 public float rotationSpeed;
17
18 public int damageToGive;
19
20 private Rigidbody2D myrigidbody2D;
21
22 // Use this for initialization
23 void Start () {
24 player = FindObjectOfType<PlayerController> ();
25
26 myrigidbody2D = GetComponent<Rigidbody2D> ();
27
28 if (player.transform.position.x < transform.position.x)
29
30 {
31 speed = -speed;
32 rotationSpeed = -rotationSpeed;
33 }
34 if (player.transform.position.x < transform.position.y)
35 {
36 speed = speed;
37 rotationSpeed = rotationSpeed;
38 }
39 }
40
41 // Update is called once per frame
42 void Update () {
43 myrigidbody2D.velocity = new Vector2 (speed, myrigidbody2D.velocity.y);
44
45 myrigidbody2D.angularVelocity = rotationSpeed;
46 }
47
48 void OnTriggerEnter2D(Collider2D other)
49 {
50 if(other.name == "Player")
51 {
52 //Instantiate(enemyDeathEffect,other.transform.position, other.transform.rotation);
53 //Destroy (other.gameObject);
54 //ScoreManager.AddPoints(pointsForKill);
55
56 //HealthManager.HurtPlayer (damageToGive);
57 }
58
59 Instantiate (impactEffect, transform.position, transform.rotation);
60 Destroy (gameObject);
61 }
62 }
