如何在另一个函数中访问 OnTriggerEnter2D 的值?

How to access a value from OnTriggerEnter2D in another function?

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

public class RedHP : MonoBehaviour
{

    public float HP = 5;
    public GameObject BlueWon;
    public GameObject Restart;

    void OnTriggerEnter2D(Collider2D trig)
    {
        if (trig.gameObject.tag == "ThrowableBlue")
        {
            StartCoroutine(BowlDestroyTime());
            HP--;
            if (HP <= 0)
            {
                BlueWon.SetActive(true);
                Restart.SetActive(true);
                PlayerBlueController.canMove = false;
                PlayerBlueController.canFire = false;
            }
        }
    }

    IEnumerator BowlDestroyTime()
    {
        yield return new WaitForSeconds(1);
        Destroy(trig.gameObject);
    }
}

我只是想在太短的时间后销毁我的对象以使其看起来更好。在 IEnumerator 中,我无法访问 trig.gameObject,因为它是在 OnTriggerEnter2D 中定义的。有没有办法访问这个值? 我还尝试将 IEnumerator 放在 OnTriggerEnter2D 中,但它也没有用。有点新手

您不必那样做。 Destroy函数可以带第二个参数作为Object被销毁前的延迟时间。

Destroy(trig.gameObject, 1f);

如果您仍想使用协程来执行此操作,只需让 BowlDestroyTime 函数将 GameObject 作为参数,然后将游戏对象从 OnTriggerEnter2D 函数传递给 BowlDestroyTime 要销毁的函数。

void OnTriggerEnter2D(Collider2D trig)
{
    if (trig.gameObject.tag == "ThrowableBlue")
    {
        StartCoroutine(BowlDestroyTime(trig.gameObject));
        HP--;
        if (HP <= 0)
        {
            BlueWon.SetActive(true);
            Restart.SetActive(true);
            PlayerBlueController.canMove = false;
            PlayerBlueController.canFire = false;
        }
    }
}

IEnumerator BowlDestroyTime(GameObject tartgetObj)
{
    yield return new WaitForSeconds(1);
    Destroy(tartgetObj);
}
