我在 Unity 控制台中收到错误消息。我想知道什么是手段以及如何解决它？

Question

如果所有敌人都被杀死并赢得比赛，我试图让玩家运送游戏对象移动到下一个场景。我在 Unity 控制台中收到错误消息：

Assets\Scripts\GameController.cs(57,25)：错误 CS0122：“SceneLoader.LoadNextScene()”因其保护级别而无法访问。

目前，我只有在改变这一行的值时才能进入下一个场景：

SceneManager.LoadScene(1); 

到场景 Loader.cs 中的 (2) 我在这里向游戏控制器添加了代码：public void WinGame() 方法对此错误的含义以及如何修复它的任何反馈表示赞赏。 :)

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneLoader : MonoBehaviour
{
    [SerializeField] float levelLoadDelay = 2f;
    private int currentSceneIndex = -1;

    private void Awake()
    {
        currentSceneIndex = SceneManager.GetActiveScene().buildIndex;
    }

    private void Start()
    {
        if (currentSceneIndex == 0)
        {
             Invoke("LoadFirstScene", 2f);
        }

        private void LoadNextScene()
        {
            int currentSceneIndex =   SceneManager.GetActiveScene().buildIndex;
            int nextSceneIndex = currentSceneIndex + 1;
            SceneManager.LoadScene(nextSceneIndex);
        }

        public void LoadFirstScene()
        {
            SceneManager.LoadScene(1);

使用您当前的代码结构，问题在于您在 start 函数中定义了方法。

修改后的脚本：

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneLoader : MonoBehaviour
{
[SerializeField] float levelLoadDelay = 2f;
private int currentSceneIndex = -1;
 public static SceneLoader instance;

private void Awake()
{
    currentSceneIndex = SceneManager.GetActiveScene().buildIndex;
instance = this;
}

private void Start()
{
    if (currentSceneIndex == 0)
    {
         Invoke("LoadFirstScene", 2f);
    }
}

    public void LoadNextScene()
    {
        int currentSceneIndex =   SceneManager.GetActiveScene().buildIndex;
        int nextSceneIndex = currentSceneIndex + 1;
        SceneManager.LoadScene(nextSceneIndex);
    }

    public void LoadFirstScene()
    {
        SceneManager.LoadScene(1);
    }

您现在可以使用代码调用 LoadNextScene：

SceneLoader.instance.LoadNextScene();
