当敌人被消灭时，我有一个粒子系统。我有多个敌人来自同一路径（使用相同的预制件），并且粒子系统仅在第一个敌人上起作用。有人可以告诉我为什么它对其他人也无效吗？谢谢。
EnemyShooting脚本（这是爆炸的代码段）：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyShooting : MonoBehaviour {
[SerializeField] float EnemyLaserSpeed = 10f;
[SerializeField] float EnemyLaserFireTime;
[SerializeField] GameObject LaserBulletEnemyPreFab;
[SerializeField] int MaxNumberOfHits = 1;
public Transform explosion;
int CurrentNumberOfHits = 0;
Coroutine FireCoroutine;
void OnTriggerEnter2D(Collider2D collider)
{
if(collider.gameObject.tag == "PlayerLaser")
{
if (CurrentNumberOfHits < MaxNumberOfHits)
{
CurrentNumberOfHits++;
Destroy(collider.gameObject);
Score.ScoreValue += 2;//The user will be rewarded 1 point
}
if (explosion)//EXPLOSION CODE
{
GameObject exploder = ((Transform)Instantiate(explosion, this.transform.position, this.transform.rotation)).gameObject;
Destroy(exploder, 2.0f);
}
}
}
void DestroyEnemy()
{
if(CurrentNumberOfHits >= MaxNumberOfHits)
{
Destroy(gameObject);
EnemySpawner.Instance.OnEnemyDeath(); // Tell the EnemySpawner that someone died
}
}
private void Fire()
{
FireCoroutine = StartCoroutine(ShootContinuously());
}
void BecomeVisible()
{
Fire();
}
IEnumerator ShootContinuously()
{
while (true)
{
GameObject LaserBulletEnemy = Instantiate(LaserBulletEnemyPreFab, this.transform.position, Quaternion.identity) as GameObject;
LaserBulletEnemy.GetComponent<Rigidbody2D>().velocity = new Vector2(0, EnemyLaserSpeed);
EnemyLaserFireTime = Random.Range(0.5f, 0.9f);
yield return new WaitForSeconds(EnemyLaserFireTime);
}
}
// Use this for initialization
void Start () {
BecomeVisible();
}
// Update is called once per frame
void Update () {
DestroyEnemy();
}
}
EnemySpawner ：（我认为此脚本可能会有所帮助，因此我将其附加了）
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class EnemySpawner : MonoBehaviour
{
[SerializeField] GameObject EnemyPreFab;
[SerializeField] int MaxEnemies = 30;
[SerializeField] float EnemySpawnTime = 1.00001f;
[SerializeField] GameObject FirstWaypoint;
int CurrentNumOfEnemies = 0;
public int EnemiesToNextLevel = 7;
public int KilledEnemies = 0;
public LevelManager myLevelManager;
public static EnemySpawner Instance = null;
int timesEnemyHit;
IEnumerator SpawningEnemies()
{
while (CurrentNumOfEnemies <= MaxEnemies)
{
GameObject Enemy = Instantiate(EnemyPreFab, this.transform.position, Quaternion.identity);
CurrentNumOfEnemies++;
yield return new WaitForSeconds(EnemySpawnTime);
}
}
void Start()
{
if (Instance == null)
Instance = this;
StartCoroutine(SpawningEnemies());
timesEnemyHit = 0;
if (this.gameObject.tag == "EnemyHit")
{
CurrentNumOfEnemies++;
}
}
public void OnEnemyDeath()
{
CurrentNumOfEnemies--;
/*
if (CurrentNumOfEnemies < 5)
{
// You killed everyone, change scene:
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
KilledEnemies++;
if (KilledEnemies >= EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("NextLevelMenu");
}
}
}
