我正在制作的游戏有一个奇怪的问题。出于某种原因，每当我从菜单切换到另一个场景时，都可以在后台看到菜单，并且它的按钮处于活动状态。所以玩家可以点击菜单按钮所在的空间（虽然实际上不在菜单屏幕上）并得到意外的响应。它只发生在这一幕上；所有其他场景都正常工作。这是有问题的脚本。

public class Menu : MonoBehaviour

Records records = new Records();
//public static Menu instance = null;

void Awake()
{
//ScreenFader.fadeToBlack = false;
//create a singleton so that there's only one instance of a menu at any time.
//if (instance != null)
// DestroyObject(this); //destroys the new instance

// instance = this;
//menu needs to persist for the duration of the game because I want the music to keep playing across multiple screens. -THIS IS NO LONGER THE CASE

records.LoadRecords();
}
// Use this for initialization

{

{

onMenuScreen = false;
}

我认为问题可能是我在现场的第二个脚本，但我禁用了它，我也遇到了同样的问题。这是另一个脚本。
/* This script is used to allow music to persist between screens. It uses a singleton to prevent more than once instance
* from being created. This script must be placed in MenuScreen scene. */

private bool musicPlaying;
private short trackNumber;
void Awake()
{
//create a singleton so that there's only one instance of a music track at any time.
if (instance != null)
DestroyObject(this); //destroys the new instance
else
instance = this;
DontDestroyOnLoad(this);
}

{

}
FileStream fs = new FileStream(directory + fileName, FileMode.OpenOrCreate);
StreamWriter writer = new StreamWriter(fs);
//write track number to file

writer.Close();
fs.Close();
}
void LoadTrackFile()
{
//start searching and reading files
string directory = Application.persistentDataPath + "/Tile Crusher/Data/";
string fileName = "trackfile.savefile";
//locate the file. If it doesn't exist, it will be created.
if (!File.Exists(directory + fileName))
{
UpdateTrackFile();
}
//read data. The file is read in a specific order.
FileStream fs = new FileStream(directory + fileName, FileMode.Open);
StreamReader fileRead = new StreamReader(fs);
//load track number
string track = fileRead.ReadLine();
trackNumber = Int16.Parse(track);
//done

}
// Update is called once per frame

{

}

困扰我的是这个问题只发生在这一场景中。我所有的其他场景都很好。我使用了一种解决方法，但我认为我不需要为这个场景做这样的事情。有人能帮忙吗？
