EndLayoutGroup: BeginLayoutGroup must be called first

I have a custom editor that appends a button to the default inspector for a ScriptableObject sub-class. When this button is pressed, I run my build. Everything seems to work, but I get the following error logged to the console after the build completes:

EndLayoutGroup: BeginLayoutGroup must be called first.

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Sometime I get this message too:

Expected top level layout group missing! Too many GUILayout.EndScrollView/EndVertical/EndHorizontal?

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

If I comment out the call to Builder.InteractiveBuild, the error message doesn't appear. Builder.InteractiveBuild merges multiple scenes into a single scene file and then calls BuildPipeline.BuildPlayer to build the project using that merged scene.

There is no GUI code in Builder.InteractiveBuild, although it does call BuildPipeline.BuildPlayer which puts up a progress dialog.

I also tried making a call to GUILayout.BeginVertical at the beginning of OnInspectorGUI to no avail.

Any ideas as to what is going on?

Here is the Editor's OnInspectorGUI:

public override void OnInspectorGUI()

{

    DrawDefaultInspector();

    EditorGUILayout.Space();



    if (GUILayout.Button("Build", GUILayout.ExpandWidth(false)))

    {

        Builder.InteractiveBuild((BuildConfiguration)target);

    }

}

 

Add GUIUtility.ExitGUI(); after Builder.InteractiveBuild((BuildConfiguration)target);
It should fix your problem. Enjoy

 

Was not aware of GUIUtility.ExitGUI(). Exactly what I needed. Thanks.

 

I m getting this same error after process the code after button clicked inside OnInspectorGUI() in unity version 2018.2.5f1 mac os.

When button click I display progress bar using EditorUtility.DisplayProgressBar() and clear it using EditorUtility.ClearProgressBar();. and also display EditorUtility.DisplayDialog() after it.
If I comment code of progress bar and display dialog error not occurred any everything works fine.

In my case GUIUtility.ExitGUI() not working. Any other way to solve this error?

 

Can you post the code?

 

Code (CSharp):

1. public override void OnInspectorGUI()
2. {
3.     GameScript gameScript = (GameScript)target;
4.     if (GUILayout.Button("Choose", GUILayout.Width(70), GUILayout.Height(20)))
5.     {
6.         string filepath = EditorUtility.OpenFilePanelWithFilters("Choose", "", filters);
7.         EditorUtility.DisplayProgressBar("Processing..", "Shows a progress", 0.2f);
8.         gameScript.ProcessFile(); //It takes 8-10 sec
9.         EditorUtility.ClearProgressBar();
10.         EditorUtility.DisplayDialog("Message", "Success.", "Ok");
11.         GUIUtility.ExitGUI();
12.     }
13. }

 

I don't know what the problem is exactly, but my guess is that you're using the API in a way the API designer didn't intend it to be used. For example, there's no point in calling DisplayProgressBar and then immediately calling ClearProgressBar in the same OnInspectorGUI invocation. In immediate mode GUI programming, you'd typically not call a bunch of functions like this in order like you have.

If you haven't read it already, make sure to read up on Immediate Mode GUI.

 

@dichardson, Actually I,m processing file by calling the method(see my updated code) in between DisplayProgressBar and ClearProgressBar and it takes 8-10 secs. Here the main problem in mac os is that after selecting the file from OpenFilePanelWithFilters the dialog windows do not disappear from the screen and ProgressBar is displayed behind the dialog windows.

Is there any way to close the dialog window after selecting the file or another way to handle this situation?

 

Huh. I took your code and put a sleep in to simulate the long processing and it actually worked fine for me on Windows 10 running Unity 2018.2.6f1.

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. [CustomEditor(typeof(NewBehaviourScript))]
5. public class NewBehaviourScriptEditor : Editor {
6.  
7.     public override void OnInspectorGUI()
8.     {
9.         if (GUILayout.Button("Choose", GUILayout.Width(70), GUILayout.Height(20)))
10.         {
11.             string filepath = EditorUtility.OpenFilePanelWithFilters("Choose", "", new string[] { "CSharp", "cs" });
12.             Debug.Log("filepath is " + filepath);
13.             EditorUtility.DisplayProgressBar("Processing..", "Shows a progress", 0.2f);
14.             System.Threading.Thread.Sleep(8000);
15.             EditorUtility.ClearProgressBar();
16.             EditorUtility.DisplayDialog("Message", "Success.", "Ok");
17.             GUIUtility.ExitGUI();
18.         }
19.     }
20. }
21.  

NewBehaviourScript was just a default MonoBehavior.

 

In windows 10 it works fine for me but my error occurs only in mac os.

 

You should report an issue. Sounds like a bug.

 

Ok. thanks

 

Nice. Thanks.

You should delete all the library not working.I just fix it recently.

 

I Don't Know What To Do
It says end layer group begin layer group must be called first
Code:

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

public class PlayerMovement : MonoBehaviour {

public CharacterController2D controller;

public float runSpeed = 40f;

float horizontalMove = 0f;
bool jump = false;
bool crouch = false;

// Update is called once per frame
void Update () {

horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;

if (Input.GetButtonDown("Jump"))
{
jump = true;
}

if (Input.GetButtonDown("Crouch"))
{
crouch = true;
} else if (Input.GetButtonUp("Crouch"))
{
crouch = false;
}

}

void FixedUpdate ()
{
// Move our character
controller.Move(horizontalMove * Time.fixedDeltaTime, crouch, jump);
jump = false;
}
}

 

I'm getting the same error when I try to import a large raw terrain map using the (Import Raw) button in the terrain settings window.

I'm starting with a fresh new project, so I do the following

Create new terrain (from dropdown menu)
go to terrain settings
Import Raw...
select file.

The message appears as soon as I select the file (at the Import Heightmap window appears). I can still edit the settings in the Import Heightmap window, so I set Terrain size at 4096, 1000, 4096, but then nothing happens.

The heightmap I'm trying to import is rather hefty (900 mb). Am I missing something?

 

I have the same, this is the code

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine;

public class PlayerControl2 : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
if(Input.GetKey("left"))
{
gameObject.GetComponent<Rigidbody>().AddForce(new Vector2(-1000f * Time.deltaTime, 0));
}
}
}

 

Can anyone help me?

 

same issue here my code is:

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

public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;

public float speed = 12f;
public float gravity = -9.81f;

Vector3 velocity;

void Update()
{
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");

Vector3 move = transform.right * x + transform.forward * z;

controller.Move(move * speed * Time.deltaTime);

velocity y +gravity * Time.deltaTime;

controller.Move(velocity * Time.deltaTime);
}
}

Hey everyone make sure you didn't click the button next to the play game button on unity 2020 that says local/global - i had this problem and same error in my game and could not play test what im making because i accidentally pressed the button at some point apparently.

 

you haven't placed the } of the class. also if your update is empty just remove it.

just place an } after update method.

 

Hey so im really new to coding, and I've been trying to make a game for fun, but I get that error and I have no idea what you said. I've tried to look everywhere but I cant find any other people that have simplified it in an easier way. Would you please be able to do that?

 

Which error? Please include the top few lines of the error from the Unity Console.

 

this is the error:
EndLayoutGroup: BeginLayoutGroup must be called first.
UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)

 

Does this occur in editor code you wrote? If so provide a code snippet and place it in the message using the Code icon in the message toolbar (which makes it easier for everyone to read).
If it just occurs sometime when using the Unity editor it is more likely an asset you downloaded from the Asset Store OR a bug in the Unity editor (which there are several that generate this error).

 

I am experiencing the same problem


when I double click here to check where its coming from, VS2019 loads, but then nothing happens. even if i double click the error again, nothing loads up on VS2019

I saw some fixes shared here, on some code, but I can't load any code to try them out.

 

im dum

 

I have same problem maybe you found an answer?

 

I am getting this error and i don't know how to trace it, all i know is that it is rooted in TextMeshPro.
Image of the error:

I am brand new to unity so i have no idea what i am doing. I have done all of the same stuff on a separate game and not had this issue before. What should I do?

EDIT: Nevermind! I just reloaded all of the scenes and that somehow got rid of the error! Unity is weird lol

 

Guys, I've found a noob solution! I create a new behaviour script with default name -> copy all the code from the previous script into it -> delete the previous script. Strange, but it works! No error!

UnityEngine.GUIUtilityrocessEvent (int,intptr)


help me?

 

Most of the posts above show this error in response to a user script. I get it whenever I import an FBX model and extract its textures and materials to a folder:

EndLayoutGroup: BeginLayoutGroup must be called first.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

​

Then, when I first drag the new model into my scene, I get this:

UnityEditor.ObjectPreview was not disposed properly. Make sure that base.Cleanup is called if overriding the Cleanup method. If you are implementing this in an Editor or EditorWindow, don't forget to call ObjectPreview.Cleanup in OnDisable.

UnityEditor.ObjectPreview:Finalize ()

​

The only scripts involved in this case are from Unity's internal codebase. Not sure what to do to prevent them, but they don't seem to indicate a real problem, since the models, textures, and materials all import fine. They just generate a lot of useless and distracting console noise in the process.

 

I don't exactly know what you're meaning but I tried extracting materials, and had to make a folder under assets to extract to. Though I'm using 2019.4.31f1 so it might not be what you're looking for.

 

My procedure is:

1. Import an FBX model
2. Create a new folder for its materials and textures
3. Under the Materials tab, click Extract Textures, and select the new folder as the destination
4. Under the Materials tab, click Extract Materials,and select the same new folder as the destination

At this point, I get the first error:

Code (CSharp):

1. EndLayoutGroup: BeginLayoutGroup must be called first.
2. UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

The second error usually waits until I place the new model into my scene hierarchy. Again, they don't seem to indicate a serious problem. Once I clear them from the console, they don't come back, and the scene plays without further problems. It's just aggravating that they show up at all, considering these are what I would consider normal editor operations, that don't involve user scripts, or any non-Unity plugins. Errors are supposed to mean something, and these apparently don't mean anything.

 

I have this error too in 2020.3+ when I import a Png image. After that is called, it returns this.

I've tried using GUIutility.ExitGUI() as recommended by some people (still don't understand what that does, really).
And putting Vertical Layouts around all items, made sure every layout group has an opening and closing action.

But still getting this error, which by the way, is internal, there is no BeginLayoutGroup anymore since a very old unity version. No idea...

 

Essentially there are multiple passes for editor layout. If not all passes have the same content, you can get this error after U2019.1 (from memory). The solution is to call the ExitGUI() to ignore all other passes immediately after you've changed the layout.

 

Thanks.
I think I mentioned I used ExitGUI(). If I run that, it shows no GUI.
