如何使用 Unity2020 C# 将 UnityEngine.Object 转换为 bool

Question

我正在开发一款你可以杀死敌人并被敌人杀死的游戏如果你杀死一个敌人，他的外观会改变当我杀死敌人时，我希望敌人的 boxcollider2D 上的 IsTrigger 选项为假，这样他的对撞机就会保留下来，但我仍然可以在他身上行走它会报错 canot convert bool to UnityEngine.Object

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

public class PlayerMove : MonoBehaviour
{
    Rigidbody2D rb;
    SpriteRenderer sr;
 
    public float jumpHeight = 5f;
    public float moveSpeed = 4f;
    public float coins = 0f;
    public bool canJump = true;
    public Sprite DeadEnemy;
    public GameObject EnemySquare;


    // Start is called before the first frame update

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
        sr = GetComponent<SpriteRenderer>();

    }
    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.W))
        {
            rb.velocity = new Vector2(rb.velocity.x, +jumpHeight);
            canJump = false;
        }
        if (Input.GetKey(KeyCode.D))
        {
            rb.velocity = new Vector2(moveSpeed, rb.velocity.y);
        }
        if (Input.GetKey(KeyCode.A))
        {
            rb.velocity = new Vector2(-moveSpeed, rb.velocity.y);
        }
    }
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.CompareTag("Coin1"))
        {
            print("Coin1");
            Destroy(collision.gameObject);
            coins = coins + 1;
        }
        if(collision.CompareTag("Chest"))
        {
            print("Coin1");
            Destroy(collision.gameObject);
            coins = coins + 2;
        }
        if(collision.CompareTag("KillEnemy"))
        {
            Destroy(collision.GetComponentInChildren<BoxCollider2D>().isTrigger = false);//This is where the problem comes from
            print("Collision");
            coins = coins + 3;
            Destroy(EnemySquare);
            collision.gameObject.GetComponent<SpriteRenderer>().sprite = DeadEnemy;
        }
        if(collision.CompareTag("KillBlock"))
        {
            print("Collision");
            SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        }
    }
}

在您的代码中，您试图销毁 collision.GetComponentInChildren<BoxCollider2D>().isTrigger = true，这不是游戏对象。

如果你想销毁游戏对象，只需传递'collsiion.GetComponentInChildren()'

另外，我不明白你为什么要破坏BoxCollider2D。如果你只想禁用它，我认为禁用它就足够了，而不是破坏它。
