Question

我知道以前here曾问过这个问题，但这是行不通的。它将GameObject成功移动到另一个场景，但没有关闭前一个场景。这是screenshot。

这是项目Expanded Screen Shot的扩展屏幕截图

这是脚本，但是在脚本中您还会找到“幻灯片显示”菜单的代码，该菜单会将我的模型显示为菜单

在功能enableScene（）中，在第1行中，我试图关闭上一个场景，但是它不起作用

public class PizzaScript : MonoBehaviour {

    public Text header;
    public  List<GameObject> createObjects = new List<GameObject>();
    private static int slideIndex = 1;
    private GameObject instance;
    private Vector3 temp = new Vector3(0.34f, 0.074f, 0);
    private AsyncOperation sceneAsync;

    public GameObject Pizza;
    public GameObject Cube;
    public GameObject Sphere;
    public GameObject CocaCola;


    // Use this for initialization
    void Start()
    {

        object[] subListObjects = { Pizza, Cube, Sphere, CocaCola };
        foreach(GameObject list in subListObjects )
        {
            GameObject lo = (GameObject)list;
            createObjects.Add(lo);
        }

        showPrefabs(slideIndex);
        StartCoroutine(loadScene(2));
    }

    IEnumerator loadScene(int index)
    {
        AsyncOperation scene = SceneManager.LoadSceneAsync(index, LoadSceneMode.Additive);
        scene.allowSceneActivation = false;
        sceneAsync = scene;

        //Wait until we are done loading the scene
        while (scene.progress < 0.9f)
        {
            Debug.Log("Loading scene " + " [][] Progress: " + scene.progress);
            yield return null;
        }
        Debug.Log("Progress Completed.............................");

    }

    public void OnFinishedLoadingAllScene()
    {
        Debug.Log("Done Loading Scene");
        enableScene(2);
        Debug.Log("Scene Activated!");
    }

    private void enableScene(int index)
    {
        SceneManager.UnloadSceneAsync(1);
        //Activate the Scene
        sceneAsync.allowSceneActivation = true;


        Scene sceneToLoad = SceneManager.GetSceneByBuildIndex(index);
        if (sceneToLoad.IsValid())
        {
            Debug.Log("Scene is Valid");
            SceneManager.MoveGameObjectToScene(instance, sceneToLoad);
            SceneManager.SetActiveScene(sceneToLoad);
        }
    }

    // Update is called once per fram

    public void OnClickRightArrow()
    {

        plusPrefabs(1);
    }

    public void OnClickLeftArrow()
    {
        plusPrefabs(-1);
    }

    public void plusPrefabs(int n)
    {
        if(n == 1 || n == -1)
        {
            Destroy(instance,0.01f);
        }

        showPrefabs(slideIndex += n);
    }

    public void showPrefabs(int n)
    {

        var x = createObjects.Count;

        if (n > createObjects.Count)
        {
            slideIndex = 1;
        }
        if (n < 1)
        {
            slideIndex = createObjects.Count;
        }

        if (slideIndex == 1)
        {
            header.text = slideIndex.ToString();
            instance = Instantiate(createObjects[0], temp, Quaternion.Euler(-90,0,0));
            instance.transform.localScale = new Vector3(20, 20, 20);
        }
        else if(slideIndex == 2)
        {
            header.text = slideIndex.ToString();
            instance = Instantiate(createObjects[1], temp, transform.rotation);
            instance.transform.localScale = new Vector3(10, 10, 10);
        }
        else if (slideIndex == 3)
        {
            header.text = slideIndex.ToString();
            instance = Instantiate(createObjects[2], temp, transform.rotation);
            instance.transform.localScale = new Vector3(10, 10, 10);
        }
        else if (slideIndex == 4)
        {
            header.text = slideIndex.ToString();
            instance = Instantiate(createObjects[3], temp, Quaternion.Euler(-90,0,0));
            instance.transform.localScale = new Vector3(120, 120, 120);
        }      

    }



}

以下是屏幕截图Screen shot of previous scene

Answer 1

在加载时将一个游戏对象持久保存到另一个场景中非常容易，只需将脚本附加到所需的游戏对象上即可。

$url2

DontDestroyOnLoad的工作方式如下：

使对象目标在加载时不会自动销毁   新场景。

加载新关卡时，场景中的所有对象均被破坏，然后   新级别的对象已加载。为了保存一个   关卡加载期间，对象调用DontDestroyOnLoad。如果   对象是组件或游戏对象，然后是其整个变换   层次结构也不会被破坏。
