【问题描述】：
一共有9个场景。所有都添加在“构建设置”中。 9 个场景中有 7 个正在加载，但是当我尝试加载其他 2 个场景时，它一直在说：
无法加载场景“SceneName”，因为它尚未添加到构建设置或 AssetBundle 尚未加载。要将场景添加到构建设置，请使用菜单 File->Build Settings... UnityEngine.SceneManagement.SceneManager:LoadSceneAsync(String, LoadSceneMode) MoreMountains.CorgiEngine.c__Iterator0:MoveNext() （在 Assets/CorgiEngine/Common/Scripts/ Managers/LoadingSceneManager.cs:88) UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator) MoreMountains.CorgiEngine.LoadingSceneManager:Start()（在 Assets/CorgiEngine/Common/Scripts/Managers/LoadingSceneManager.cs:67）
我已经在场景管理器中添加了场景，但它一直显示这个错误。我已经尝试了很多。请帮我解决问题。这是我的“LoadingSceneManager”脚本：
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using MoreMountains.Tools;
using UnityEngine.SceneManagement;
namespace MoreMountains.CorgiEngine

}

/// </summary>
protected virtual IEnumerator LoadAsynchronously()
{
// we setup our various visual elements
LoadingSetup();
// we start loading the scene
_asyncOperation = SceneManager.LoadSceneAsync(_sceneToLoad,LoadSceneMode.Single );
_asyncOperation.allowSceneActivation = false;
// while the scene loads, we assign its progress to a target that we'll use to fill the progress bar smoothly
while (_asyncOperation.progress < 0.9f)
{
_fillTarget = _asyncOperation.progress;
yield return null;
}
// when the load is close to the end (it'll never reach it), we set it to 100%
_fillTarget = 1f;
// we wait for the bar to be visually filled to continue
while (LoadingProgressBar.GetComponent<Image>().fillAmount != _fillTarget)
{
yield return null;
}
// the load is now complete, we replace the bar with the complete animation
LoadingComplete();
yield return new WaitForSeconds(LoadCompleteDelay);
// we fade to black
GUIManager.Instance.FaderOn(true,ExitFadeDuration);
yield return new WaitForSeconds(ExitFadeDuration);
// we switch to the new scene
_asyncOperation.allowSceneActivation = true;
}

StartCoroutine(MMFade.FadeCanvasGroup(LoadingCompleteAnimation,0.1f,1f));
}
}
}
【问题讨论】：
-
“我已经在场景管理器中添加了场景”是什么意思？您是在谈论构建设置吗？ （菜单
File>Build Settings）。您确定您尝试加载的场景名称正是构建设置中的场景名称吗？ -
只是关于样式的附注，您不需要在 C# 中为私有/受保护的变量添加下划线前缀。您可以使用
this.sceneToLoad = sceneToLoad而不是下划线语法。 -
@Hellium 是的，我在谈论构建设置，我要加载的所有场景都在具有正确名称的构建设置中，但仍然显示错误
-
@Hellium 是的，它也被检查了。我已经更新了问题，还添加了构建设置屏幕截图链接。请检查一下
-
@Hellium out of 9 Scenes 它只打开了 7 个场景，当尝试打开“Level1”和“Level4”时它显示错误。
