I am trying to get my game so when you die and the death screen pops up, the obstacles stop moving. This is the error message that pops up:
NullReferenceException: Object reference not set to an instance of an object FlipGravity.Update () (at Assets/Scripts/FlipGravity.cs:56)
What is the error in my code?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
public class FlipGravity : MonoBehaviour {
private Rigidbody2D rb;
public int health = 3;
public Text ScoreText;
public int NumOfHearts;
public Image[] hearts;
public Sprite FullHeart;
public Sprite EmptyHeart;
public GameObject GameOver;
void Start(){
rb = GetComponent<Rigidbody2D>();
}
void Update(){
for (int i = 0; i < hearts.Length; i++)
{
if(i<health)
{
hearts[i].sprite = FullHeart;
} else
{
hearts[i].sprite = EmptyHeart;
}
if(i < NumOfHearts){
hearts[i].enabled = true;
}else {
hearts[i].enabled = false;
}
}
if(Input.GetKeyDown(KeyCode.Space)){
rb.gravityScale *= -1;
}
if(health <= 0){
GameOver.SetActive(true);
Destroy(gameObject);
//GetComponent<Obstacle>().speed = 0;
GameObject Spikes = GameObject.Find("Spikes");
Obstacle playerScript = Spikes.GetComponent<Obstacle>();
playerScript.speed = 10f;
}
if(health > 0){
GameOver.SetActive(false);
}
}
/*void OnTriggerEnter2D(Collider2D other){
if(health <= 0){
other.GetComponent<Obstacle>().speed = 0;
}
}*/
}
Just to clarify, it lets me start and the error message pops up after I die
