[SOLVED] SceneManagement does not exist in the namespace 'UnityEngine'

Hi All,

I'm currently using Unity 5.1.1f1 Pro version and want to use SceneManager.LoadSceneAsync():
http://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadSceneAsync.html

But Apparently UnityEngine does not contain SceneManagement namespace.

I'm getting " SceneManagement does not exist in the namespace 'Unity Engine' " on the line:
using UnityEngine.SceneManagement;

The forum posts I've stumbled upon are all about Application.LoadLevel, which is obsolete in the new version:
http://docs.unity3d.com/ScriptReference/Application.LoadLevel.html

Thanks in advance.

 

Update to Unity 5.3 fixed the issue.

 

Hurm. That did not fix it for me. I just updated to Unity 5.3.0f4 and I am stuck between Application.LoadLevel is obsolete and The name 'SceneManager' does not exist in the current context.

 

Adding "UnityEngine.SceneManagement;" worked for me

 

Despite adding "UnityEngine.SceneManagement;" on top, I still had to write
"UnityEngine.SceneManagement.SceneManager.LoadScene(.......
to get it to compile...strange.

 

How if we want to downgrade the script contains 'SceneManagement' ?

 

Hey guys what's the difference between Application.LoadLevelAsync and SceneManager.LoadSceneAsync (as I remember ) ??

 

[FIXED]
Even after I use all these tips it still gives the same error message that we had in the first place. Any ideas on what might be going wrong?

*EDIT* I Realised I had a bit of code in another script one wrong! So no need to respond, thanks to all who were going to though!

 

if you added using scenemanagement you only have to call scenemanager.loadscene("scene01");

 

[Fixed]Hi ^^ I have a problem with the libraries and my script can't read this lines:

using UnityEngine;
using UnityEngine.SceneManagement;

Also, i have this library that not appears in other tutorials what i see

using System.Collections.Generic;

This is the complete code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class Controlador : MonoBehaviour {

public void CambiarEscena(string nombre) {
print("Cambiando a la escena " + nombre);
SceneManager.LoadScene (nombre);
}

public void Salir() {
print ("Saliendo del juego");
}

}

I dont know where is the mistake.

Sorry. I only have to reset the program

 

Hmm, I had this as well but then I realized I have a script called "SceneManager" for my whole scene. See the problem? Writing SceneManager in the code was mistaken to be the MonoBehavior I had instead of what's in the 'using' directive. Renamed to GameManager and stuff works

 

i still have the first problem about use SceneManager.LoadScene.
can anybody help my?

 

@mika_2004_kv - what did you try mentioned above that didn't work? Post #4 (link) on this thread should fix this.

 

already add UnityEngine.SceneManagement; but it still gives error while build

 

look if you are not using the updated version of visual studio, I had this problem because of the unity hub.

 

I've tried everything you guys have said and it still doesn't work...

 

I still can't get it to work either

 

If you have both...

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;

They both contain a namespace for SceneManagement.
That was causing the problem for me.

What I did to fix it was to remove the

Code (CSharp):

1. using UnityEditor;

line and use fully qualified names for Editor methods.

Code (CSharp):

1. UnityEditor.SceneManagement.EditorSceneManager.MarkSceneDirty(SceneManager.GetActiveScene());

In the line above, I'm using both namespaces but only fully qualifying the UnityEditor namespace.

 

That fixed it for me, thank you!

 

This is a piece of code I used and it has the same thing along the bottom, saying that SceneManager doesn't exist in the name space. Any help would be greatly appreciated.

*EDIT* Woops, I suck at spelling :') I apologize for wasting anyone's time! I found the error

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.SceneMenagement;



public class LevelLoader : MonoBehaviour

{

 

    public Animator transition;



    public float transitionTime = 1f;

 

    // Update is called once per frame

    void Update()

    {

        if(Input.GetMouseButtonDown(0))

        {

            LoadNextLevel();

        }

    }



    public void LoadNextLevel()

    {

        StartCoroutine(LoadLevel(SceneManager.GetActiveScene().buildIndex + 1));

    }



    IEnumerator LoadLevel(int levelIndex)

    {



        transition.SetTrigger("Start");



        yield return new WaitForSeconds(transitionTime);



        SceneManager.LoadScene(levelIndex);

    }

}

 

I already have that line. Im using a tutorial.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.SceneManagement;
3. public class GameManager : MonoBehaviour {
4.     bool GameHasEnded = false;
5.     public float restartDelay = 1;
6.     public void GameOver ()
7.     {
8.         if(GameHasEnded==false)
9.         {
10.             GameHasEnded = true;
11.             Debug.Log("Game Over");
12.             Invoke("Restart", restartDelay);
13.         }
14.     }
15.     void Restart (){
16.         SceneManagement.LoadScene(SceneManagement.GetActiveScene().name);
17.     }
18. }

 

I tried everything in this string of comments, nothing worked! I still have the same problem

 

how to do that,
Can you please guide me

 

Assets\ball.cs(16,39): error CS0103: The name 'SceneManager' does not exist in the current context
Assets\ball.cs(17,13): error CS0103: The name 'SceneManager' does not exist in the current context

using UnityEngine;

public class ball : MonoBehaviour
{
Vector3 _initialPosition;

private void Awake()
{
_initialPosition = transform.position;
}

private void Update()
{
if (transform.position.y > 10)
{
string currentSceneName = SceneManager.GetActiveScene().name;
SceneManager.LoadScene(currentSceneName);
}
}

private void OnMouseDown()
{
GetComponent<SpriteRenderer>().color = Color.blue;
}

private void OnMouseUp()
{
GetComponent<SpriteRenderer>().color = Color.white;

Vector2 directionToInitialPosition = _initialPosition - transform.position;

GetComponent<Rigidbody2D>().AddForce(directionToInitialPosition * 600);
GetComponent<Rigidbody2D>().gravityScale = 1;
}
private void OnMouseDrag()
{
Vector3 newPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
transform.position = new Vector3(newPosition.x, newPosition.y);
}
}

 

Code (CSharp):

1. using UnityEngine.SceneManagement;
2. SceneManager.LoadScene("Game");

you guys prolly did typo like me. Management & Manager

 

yo cargo mismo error no he popdido solucionarlo

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Runtime.Hosting;
4. using System.Runtime.InteropServices;
5. using UnityEngine.SceneManagement;
6.  
7. public class Controlador :  MonoBehaviour
8. {
9.     //este codigo es para cambio de escena a el tutorial
10.  
11.     public void CambiarEscena(string nombre)
12.     {
13.  
14.        
15.         print("Cambiando escena"+nombre);
16.         SceneManagement.LoadScene(nombre);
17.     }
18.  
19.     public void Salir()
20.     {
21.  
22.         print("saliendo del juego..");
23.        
24.         Application.Quit();
25.    
26.     }
27.  
28.  
29. }
30.  

 

Gracias esta es la mejor respuesta que soluciona todo el problema

 

I have the same problem with a UnityEngine.SceneManagement and MonoBehaviour not been recognised in VS 2015 after updating Unity to 2020 version. I made the game when i had Unity 2019 version, everything was ok. Now those namespaces aren't recognised in my VS 2015.

 

Not sure if this will fix it for you but I had a similar issue and figured it out.

My editor script was in an assembly definition and I forgot to mark the assembly platform to "Editor".

Project built just fine afterwards.

 

Mine dosent work here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class MainMenu : MonoBehaviour{

public void PlayGame ()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1)

}
it says scene manager does not cointain a definition for LoadScene\
EDIT:nvm i found it

 

What it is, i got the same problem.

 

It worked when i added
using UnityEngine.SceneManagement;

 

Hey guys,
using unity 4.7.2
I'm trying all of these methods but none of them are working out
could I get any help to change the scene
thx in advance

 

Tried all amoeba methods but not working. Can someone help out?

 

I had this problem and ended up trying something completely different. Don't know if this will help anyone but this is what I ended up doing:

I had "using UnityEngine.SceneManagement;" and "using UnityEditor.SceneManagement;" when I had the error. I tried fully qualifying the UnityEditor commands and removing the include for them like RareRooster suggested, but still got the error.

I realised the error was only coming up when I was actually building the game, not while using it in the editor, and I had no need for those commands at run time (they were just scripts I was running to help build a scene).

So I put all of the UnityEditor-related commands within an "#if UNITY_EDITOR" ... "#endif" directive, and then Unity could build the game without problems.
