Question

我尝试删除一个游戏对象（通电）但是即使在我删除它之后，粒子也会自我克隆。我怎么能解决这个问题？

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

public class PowerUp : MonoBehaviour {

    public float multiplier = 1.4f;
    public float duration = 4f;

    public GameObject pickupEffect;

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Player"))
        {
           StartCoroutine (Pickup(collision));
        }
    }

    IEnumerator Pickup(Collider2D player)
    {
        Debug.Log("Power up picked up!");

        Instantiate(pickupEffect, transform.position, transform.rotation;

        PlayerStats stats = player.GetComponent<PlayerStats>();
        stats.health *= multiplier;

        GetComponent<SpriteRenderer>().enabled = false;
        GetComponent<Collider2D>().enabled = false;


        yield return new WaitForSeconds(duration);

        stats.health /= multiplier;

        Destroy(this);
    }
}

在你的协程结束时，将Destroy(this);更改为Destroy(gameObject);

Destroy(this);销毁PowerUp组件。而Destroy(gameObject);会摧毁整棵树。

同样可以连续多次调用OnTriggerEnter2D，导致无限的实例化。您可以在StartCoroutine之前添加约束以防止这种情况发生。

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.CompareTag("Player"))
    {
       if (!flag)
           StartCoroutine (Pickup(collision));
    }
}

IEnumerator Pickup(Collider2D player)
{
    flag = true;
