UNITY在加载场景后不能改变transform.position

Question

我的C＃scirpt有些问题。所以，问题是加载场景后，obj正在移动到场景的起始位置，而不是我设置的位置。有人可以帮我解决这个超级难题。请。

仍然无法正常工作，我尝试制作IEnumerator，但这仍然没有用，有什么新想法吗？：＆lt;

    {
        if (File.Exists (Application.dataPath + "/save.txt")) 
        {
            BinaryFormatter bf = new BinaryFormatter ();
            FileStream file = File.Open (Application.dataPath + /save.txt",FileMode.Open);
            PlayerData data = (PlayerData)bf.Deserialize (file);
            file.Close ();

            levelName = data.levelName;
            blueWaffle = data.blueWaffle;
            posX = data.posX;
            posY = data.posY;
            posZ = data.posZ;




            SceneManager.LoadScene (levelName);

            if (SceneManager.GetActiveScene() == SceneManager.GetSceneByName(levelName)) 
            {
                //Vector3 loadedPosition = new Vector3 (posX, posY, posZ);


                Debug.Log ("I changed my position" + posX + posY + posZ);
                ScoreManager.Reset ();
                ScoreManager.AddPoints (blueWaffle);
                //player.GetComponent<Transform> ().position = loadedPosition;
                if (loaded (posX, posY, posZ)) {

嗯...为什么它看起来像你的帖子我的代码？ ：d

您正在尝试访问您正在加载它的同一帧中的场景中的数据。

等待场景结束，直到你设置对象的位置为止。

AsyncOperation asyncLoadLevel;

IEnumerator LoadLevel()
{
    asyncLoadLevel = SceneManager.LoadSceneAsync(levelName, LoadSceneMode.Single);
    while (!asyncLoadLevel.isDone)
    {
        print("Loading the Scene");
        yield return null;
    }
    //the game has finished loading
    ScoreManager.Reset();
    ScoreManager.AddPoints(blueWaffle);
    //player.GetComponent<Transform> ().position = loadedPosition;
    if (loaded(posX, posY, posZ))
    {
        Debug.Log("I changed my position");
    }
    else
    {
        Debug.Log("I didint change my position");
    }
    Time.timeScale = 1f;
}
