c# - 我正在尝试将一个脚本中的 var 值从 C# 中的另一个脚本中统一更改

Question

我有两个脚本 button.cs 附加到“开始”按钮对象并带有标志 var。并将 Restart.cs 附加到 RestartButton 对象。我正在尝试从 Restart.cs 中的 Button.cs 更改布尔标志。我得到这个错误：

Assets\Scripts\Restart.cs(14,63): error CS0122: 'Button.flag' is inaccessible due to its protection level

这是button.cs：

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

public class Button : MonoBehaviour
{
    // Start is called before the first frame update
    public GameObject m_cube, obeme, resetButton;
    public AudioSource audioSource;
    public bool flag = false;
    void  OnMouseDown(){
       
        if (!flag)
        {
        flag = true;
        transform.localRotation = Quaternion.Euler(0, 0, 180);
        m_cube.GetComponent <Animation> ().Play ("cubeGoDown2");
        audioSource.Play();
        obeme.GetComponent <Animation> ().Play ("obemeGetIn");
        resetButton.GetComponent <Animation> ().Play ("RestartButtonGetIn");
        } 
    }
}

这是Restart.cs：

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

public class Restart : MonoBehaviour
{
    // Start is called before the first frame update
    public GameObject resetButton;
    void  OnMouseDown()
    {
    transform.localRotation = Quaternion.Euler(0, 0,0);
        

       GameObject.Find("Start button").GetComponent<Button>().flag = false;;
    
    resetButton.GetComponent <Animation> ().Play ("RestartButtonGetOut");
    }
}

Answer 1

按钮类 Start Button 是统一的预定义字符串。所以我建议两件事之一。

首先：//创建从重置到开始按钮的直接引用

   //like this

   //Variables
   public GameObject myStartButton;

 public GameObject resetButton;
    void  OnMouseDown()
    {
    transform.localRotation = Quaternion.Euler(0, 0,0);
        

       myStartButton.flag = false;
    
    resetButton.GetComponent <Animation> ().Play ("RestartButtonGetOut");
    }

或者只是轻松地使名称独一无二。
