将GameObject移动/转移到另一个场景 [英] Move/Transfer GameObject to another scene

问题描述

我们尝试了将UI对象移动到另一个场景的不同方法，但是失败了.上方的对象位于画布"中.

We tryed different ways to move UI-object to another scene, but we failed. Over object is in Canvas.

方法1:我们使用了LoadLevelAdditive，但是从第一个场景开始将所有对象移到画布上，而没有其元素在上方.

Method 1: we used LoadLevelAdditive, but there moved all objects from first scene without over Canvas with it's elements.

方法2:我们使用了DontDestroyOnLoad.我们需要在Canvas上更改元素. DDOL保存了场景中的最后一个位置，但是我们根本无法更改对象.

Method 2: we used DontDestroyOnLoad. We need to change our element on Canvas. DDOL save last position on the scene, but we can't change object at all.

请问您可以得到一些建议吗?

Can you get some advice, please?

谢谢.

推荐答案

请勿使用Application.LoadLevelXXX.这些是不推荐使用的功能.如果您使用的是旧版本的Unity，请进行更新，否则，您可能无法使用以下解决方案.

Don't use Application.LoadLevelXXX. These are deprecated functions. If you are using old version of Unity, please update it otherwise, you may not be able to use the solution below.

首先，用SceneManager.LoadSceneAsync加载场景.将allowSceneActivation设置为false，以使场景在加载后不会自动激活.

First, load scene with SceneManager.LoadSceneAsync. Set allowSceneActivation to false so that the scene won't activate automatically after loading.

解决您问题的主要方法是 SceneManager.MoveGameObjectToScene 该函数用于将GameObject从一个场景转移到另一个场景.加载场景后进行调用，然后调用 SceneManager.SetActiveScene 激活场景.下面是一个例子.

The main solution to your problem is the SceneManager.MoveGameObjectToScene function which is used to transfer GameObject from one scene to another. Call that after loading the scene then call SceneManager.SetActiveScene to activate the scene. Below is an example of that.

public GameObject UIRootObject;
private AsyncOperation sceneAsync;

void Start()
{
    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;
    }
    OnFinishedLoadingAllScene();
}

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


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

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