I'm making a script that allows the player to fire bullets at an enemy but when I finished making it I got this error:
NullReferenceException: Object reference not set to an instance of an object
Playershooting.Attack () (at Assets/Scripts/Player Scripts/Playershooting.cs:40)
Playershooting.Update () (at Assets/Scripts/Player Scripts/Playershooting.cs:27)
Here are my scripts being used:
using UnityEngine;
using System;
[RequireComponent(typeof(AudioSource))]
public class Playershooting : MonoBehaviour {
public Vector3 bulletOffset = new Vector3 (0, 0.5f, 0);
public float attackDelay = 0.5f;
public int attackDamage = 10;
public GameObject playerBullet;
GameObject enemy;
DamageHandlerEnemy damageHandlerEnemy;
AudioSource shotSound;
float timer;
void Awake () {
enemy = GameObject.FindGameObjectWithTag ("Enemy");
damageHandlerEnemy = enemy.GetComponent ();
shotSound = GetComponent ();
}
void Update () {
timer += Time.deltaTime;
if (timer >= attackDelay) {
Attack ();
}
}
void Attack () {
Vector3 offset = transform.rotation * new Vector3 (0, 0.5f, 0);
if (Input.GetButton("Fire1")) {
timer = 0f;
shotSound.Play ();
Instantiate (playerBullet, transform.position + offset, transform.rotation);
}
if(damageHandlerEnemy.currentEnemyHealth > 0) {
damageHandlerEnemy.enemyDamaged (attackDamage);
}
}
}
using UnityEngine;
using System.Collections;
public class DamageHandlerEnemy : MonoBehaviour {
public int startEnemyHealth = 10;
public int currentEnemyHealth;
bool isdamaged;
bool isDead;
void Awake () {
currentEnemyHealth = startEnemyHealth;
}
void Update () {
}
public void enemyDamaged(int amount) {
isdamaged = true;
currentEnemyHealth -= amount;
if (currentEnemyHealth <= 0 && !isDead) {
Death ();
}
}
void Death() {
isDead = true;
Destroy (gameObject);
}
}
