我在构建设置中总共有五个级别。我需要加载。当玩家去世时场景切换到重新启动场景。我有重启场景代码。所以它只重新启动当前场景。我不希望它那样做。我需要重新加载以前的。我需要和其他级别一样。这是我的代码：
{
#pragma strict
import UnityEngine.SceneManagement;
@script AddComponentMenu ("EGUI/UI_Elements/Button")
// public class EGUI_Button extends EGUI_Element {}
// List of built-in functionality types
public enum ButtonAction

None, // Do nothing
Custom, // Call function (name in callFunction) with parameter for actionRecipient object (this gameObject is default)
LoadLevel, // Load level with index/name in parameter
RestartLevel, // Restart current level
ExitGame, // Close application
SetQuality, // Set quality level according to parameter (Fastest, Fast, ... Fantastic)
DecQuality, // Decrease quality level
IncQuality, // Increase quality level
SetResolution, // Set screen resolution according to parameter (1024x768, 1920x1080 ... etc)
OpenURL, // Open URL specified in parameter
CloseEverything, // Close/disable whole GUI manager and all related GUI-elements.
Resume, // Close parent GUI-element and set time-scale to 1
ShowAnother, // Show GUI-element specified in actionRecipient
ShowPrevious, // Show previous GUI-element
HideThis, // Hide parent GUI-element
HideThis_ShowAnother, // Hide parent GUI-element and show window specified in actionRecipient
HideThis_ShowPrevious, // Hide parent GUI-element and show previous window
SoundSwitch, // Enable/Disable all sounds in the scene

首先，
Application.LoadLevel＆amp; Application.loadedLevel已过时。
见：
Application.LoadLevel Reference
Application.loadedLevel Reference
相反，Unity建议您使用Scene Management API中的SceneManager类。
我的建议是做这样的事情以重新加载当前场景：
// reload the current scene
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
// load the previous scene
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex - 1);

使用此C＃脚本使您的任务更加轻松。
私有列表sceneHistory = new List（）; //场景的运行历史 //列表中的最后一个字符串始终是当前正在运行的场景
void Start()
{
DontDestroyOnLoad(this.gameObject); //Allow this object to persist between scene changes
}
//Call this whenever you want to load a new scene
//It will add the new scene to the sceneHistory list
public void LoadScene(string newScene)
{
sceneHistory.Add(newScene);
SceneManager.LoadScene(newScene);
}
//Call this whenever you want to load the previous scene
//It will remove the current scene from the history and then load the new last scene in the history
//It will return false if we have not moved between scenes enough to have stored a previous scene in the history
public bool PreviousScene()
{
bool returnValue = false;
if (sceneHistory.Count >= 2) //Checking that we have actually switched scenes enough to go back to a previous scene
{
returnValue = true;
sceneHistory.RemoveAt(sceneHistory.Count -1);
SceneManager.LoadScene(sceneHistory[sceneHistory.Count -1]);
}
return returnValue;
}
