问题：当敌人活着时，它的子弹脚本爆炸效果会反复发生在其身体对象上。当我杀死敌人时，子弹开始按原样射出。为什么子弹只有在敌人死亡时才起作用？ screenshot from bullet exploding on gameobject

项目符号脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BulletScriptEnemy : MonoBehaviour
{

    GameObject target;
    public float speed;
    Rigidbody2D bulletRB;
    //
    public GameObject hitEffect;
    public int damage = 40;
    public Rigidbody2D rb;
    //

    
    // Start is called before the first frame update
    void Start()
    {
        bulletRB = GetComponent<Rigidbody2D>();
        target = GameObject.FindGameObjectWithTag("Player");
        Vector2 moveDir = (target.transform.position - transform.position).normalized * speed;
        bulletRB.velocity = new Vector2(moveDir.x, moveDir.y);
        Destroy(this.gameObject, 2);
    }
    
    void OnTriggerEnter2D(Collider2D hitInfo)
   {
GameObject effect = Instantiate(hitEffect, transform.position, Quaternion.identity);
Destroy(effect, 2f); //Sekundes 
Destroy(gameObject);
      Player player = hitInfo.GetComponent<Player>();
      if(player != null)
      {
         player.TakeDamage(damage);
      }
      Destroy(gameObject);
   }

    // Update is called once per frame
    void Update()
      {
       
    }

}

敌人的脚本：

public class Enemy : MonoBehaviour
{
    public Animator animator;
    public int maxHealth = 100;
    //public GameObject deathEffect;
    int currentHealth;
    // Start is called before the first frame update
    void Start()
    {
        currentHealth = maxHealth;
    }

    public void TakeDamage(int damage)
    {
        currentHealth -= damage;
        //Play hurt animation
        animator.SetTrigger("Hurt");

        if(currentHealth <= 0)
        {
            Die();
        }
    }
    void Die()
    {   
        Debug.Log("Enemy died!");
        //Instantiate(deathEffect, transform.position, Quaternion.identity);
        //Destroy(gameObject);
        //Die anim
        animator.SetBool("IsDead", true);
        //Disable the enemy
        GetComponent<Collider2D>().enabled = false;
        this.enabled = false;
    }
    }

【问题讨论】：

子弹在与玩家发生碰撞之前必须与敌人发生碰撞。更改子弹生成位置

标签： c# unity3d

【解决方案1】：

难道敌人也有对撞机？当子弹被实例化时，它的 OnTriggerEnter2D 被调用，因为它击中了敌人。在 OnTriggerEnter2D 内部，您应该首先检查与您碰撞的游戏对象是否是玩家。像这样的：

void OnTriggerEnter2D(Collider2D hitInfo)
{
    Player player = hitInfo.GetComponent<Player>();
    if (player == null)
        return;

    GameObject effect = Instantiate(hitEffect, transform.position, Quaternion.identity);
    Destroy(effect, 2f); //Sekundes 
    Destroy(gameObject);
    player.TakeDamage(damage);
}

【解决方案2】：

感谢您的回答。是的，敌人有对撞机，将代码更改为此解决了问题：

void OnTriggerEnter2D(Collider2D hitInfo)
{
    Player player = hitInfo.GetComponent<Player>();
    if (player == null)
        return;

    GameObject effect = Instantiate(hitEffect, transform.position, Quaternion.identity);
    Destroy(effect, 2f); //Sekundes 
    Destroy(gameObject);
    player.TakeDamage(damage);
}

如果其他人回答了你的问题，你不应该自己写答案。你应该接受它。
