无法从另一个脚本访问变量

Question

Assets\Scripts\Wood.cs(32,9): error CS0201: 只有赋值、调用、递增、递减、等待和新对象表达式可以用作语句

我正在尝试将布尔值 hasTorch 放入脚本 Wood.cs 以了解玩家是否有手电筒。

（我是新手，所以可能很容易修复，我只是不知道：c）

脚本 1 (Chest.cs)：

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

public class Chest : MonoBehaviour
{
    public Sprite openChest;

    public GameObject chest1;
    public GameObject chestBox;
    public GameObject torch;

    public bool hasTorch = false;

    public GameObject darkness;
    public GameObject chatBox;

    private void OnTriggerEnter2D(Collider2D other)
    {
        chest1.GetComponent<SpriteRenderer>().sprite = openChest;
        torch.SetActive(true);
        chatBox.SetActive(true);
        darkness.SetActive(false);
        chestBox.SetActive(false);

        hasTorch = true;
    }

    public void Close()
    {
        chatBox.SetActive(false);
    }

}

脚本 1 (Wood.cs)：

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

public class Wood : MonoBehaviour
{

    public GameObject chestScript;
    public Chest script;

    public GameObject chatBox;

    private void OnTriggerEnter2D(Collider2D other)
    {
        if (script.hasTorch == true)
        {
            chatBox.SetActive(true);
        }

        if (script.hasTorch == true)
        {
            chatBox.SetActive(true);
        }
    }

    public void Close()
    {
        chatBox.SetActive(false);
    }

    void Start(){
        chestScript.GetComponentInChildren<Chest>().hasTorch;
    }

}

Answer 1

这一行没有做任何事情：

chestScript.GetComponentInChildren<Chest>().hasTorch;

您可以像这样记录它或将其设置为真/假：

chestScript.GetComponentInChildren<Chest>().hasTorch = false;
