I can't build my game

Here's the message what i get: cannot build player while editor is importing assets or compiling scripts
I'm not importing or compiling anything. I already tried to restart Unity, but didn't worked.
Package manager:

 

Show us console errors.

 

Hello dude, i already solved it.

 

Well, what was it? I have the same issue.

 

Never mind, I fount it, too. I had using UnityEditor in my script and removed it. Now I can build.

 

I have the same issue.

 

check your script, which one had "using UnityEditor", delete it.

 

guys i have the same issue and really confused what to do.

 

Was this what was in your log?
Build completed with a result of 'Failed'
UnityEngine.GUIUtility: ProcessEvent(Int32, IntPtr)

 

Look through all of the script you can. At the top of one there may be a line that says, "using UnityEditor;" Erase that and fix errors that it may cause.

I don't know if there is a search function that will let you look for that, but if there is utilize that. I downloaded a pack that was actually from Unity themselves and the thing had the "using UnityEditor;" in it.

 

I have the same issue

 

how do you check your scripts

 

I checked all my scripts and it still does not work

 

My scripts say using UnityEngine. Is that the same as unityeditor?

 

If you are using 3rd party tools like snaps tools which use unityeditor then delete it for once you can import again. It works for me

 

Which script I have to check? the script uneditable!

 

Hi, I deleted all of them but I still cannot build! any solutions?

 

Any in video solution, please?

 

go to the Project winndow> Assets folder> Scripts
hope that helps

 

I need help with same issue guys, please.
I have just installed Unity and following the Kart tutorial created my first game, I wanted to try it on my Android phone6 but when I click Build and Run, it shows this:

 

I know you figured it out, but did you have a JDK (Java Development Kit) ?

 

having the same issue, used find in files to locate all using UnityEditor. In all cases they were under an Editor folder, so all should be ok. Just in case I added "
#if UNITY_EDITOR" before the using line and #endif at the end of the file. Still having the same error.

Any other things that can cause this msg?

 

I got the solution that unity tell you there is some scripts has errors you should delete it and delete the GI cash.. that's helped me

 

Moreover, if you still need using UnityEditor :

Code (CSharp):

1. #if UNITY_EDITOR
2.  
3. using UnityEditor;
4.  
5. #endif

or put the script containing using UnityEditor in a folder named Editor. I usually put a parent folder (with the script name for ex) in which I create the Editor folder at the root of Assets.

 

How did you fix it

 

I have that, have you found a way to fix it?

EDIT: Nevermind, I fixed it. I just needed to remove using UnityEngine.System.Security.Policy.

 

same problem here, it does not specify which scripts are to blame, after like 20 yrs of dev they havent done that

 

Seriously.. Is it bolt that is doing this??

 

im not even using bolt, it could be literally anything, but unity see fit not to give us a clue for some reason

 

Remove every line from every script start with "using" which are not used in you project but by default unity write it.

Like from picuter
Using System.collections;
Using System. Collection. Generic;
etc.
Should remove

These will dim in color from other
Namespaces

 

If you are on Windows you can use PowerShell to find out what files contain "using UnityEditor". Open PowerShell and go to your projects Asset folder and type the following command:

Get-ChildItem -Recurse | Select-String "using UnityEditor" -List | Select Path

That should give you a complete list of all the files that are using it.

 

thanks so when it fails it does not report that it failed due to "using UnityEditor" or report the file that is using it ?

 

Correct, it only gives the "cannot build player while editor is importing assets or compiling scripts" message.

 

Hey great thanks! I will sort that out asap!.. I think thye need to fix that tho

 

Had this issue after using a free asset for a fireball.
Had built ok yesterday so that was the obvious suspect.

Removed this asset and built ok.
Thanks for the help.

And yes it was using Unity.Editor

 

I tried both it didn't help

 

did it still fail with no error? also did u search the code files to make sure all references to nityeditor are enclosed in preprocessors?

 

You need to put #if UNITY_EDITOR and #endif in every files that using UnityEditor and also put them inside the class body. Please see the example below.

Code (CSharp):

1.  
2. using UnityEngine;
3. #if UNITY_EDITOR
4. using UnityEditor;
5. #endif
6.  
7. namespace PolyPerfect
8. {
9.     [CustomEditor(typeof(Common_WanderManager))]
10.     public class Common_WanderManagerEditor : Editor
11.     {
12. #if UNITY_EDITOR
13.         public override void OnInspectorGUI()
14.         {
15.             //Load a Texture (Assets/Resources/Textures/texture01.png)
16.             var mainTexture = Resources.Load<Texture2D>("ManagerLogo");
17.             GUILayout.BeginHorizontal();
18.             if (GUILayout.Button(mainTexture))
19.             {
20.                 Application.OpenURL("https://assetstore.unity.com/?q=Polyperfect&orderBy=0");
21.             }
22.             GUILayout.EndHorizontal();
23.  
24.             Common_WanderManager Manager = (Common_WanderManager)target;
25.  
26.             if (!Application.isPlaying)
27.             {
28.                 base.OnInspectorGUI();
29.                 return;
30.             }
31.  
32.             GUILayout.Space(10);
33.  
34.             Manager.PeaceTime = EditorGUILayout.Toggle("Peace Time", Manager.PeaceTime);
35.  
36.             GUILayout.Space(5);
37.  
38.            if (GUILayout.Button("Kill 'Em All"))
39.             {
40.                 Manager.Nuke();
41.             }
42.         }
43.     }
44. #endif
45. }
46. }

 

Thanks a lot i had using UnityEditor.graphview in my controlscript so erasing that helped it

 

THANKS YOU SOOO MUCH! IT WORKS...

 

Hey Adisak, thx for your infomation. I have imported some plugins to my project. I found some files of plugins outside of the folder "Editor" but the codes"using UnityEditor;" of which is inside the "#if UNITY_EDITOR". If I move those files to the folder "Editor" it may cause some erros Missing references. So I dont know what should I do for my problems is better.....

 

Hey, MlleBun, I have imported some plugins into my project, and almost all files have codes "using UnityEditor" are inside of the folder "Editor" , and others are used codes "#if UNITY_EDITOR" for them. I tried to remove the codes "using UnityEditor" of the scripts that outside of the folder "Editor", but it still not work for me, if there any other ideas? thx for your help.

 

If you search all .cs files for these things and wrap them in #if UNITY_EDITOR, it should work

using UnityEditor
[ContextMenu
OnDrawGizmos

if you still have issues sometimes you get a clue from the editor log
at C:\Users\user\AppData\Local\Unity\Editor

I went through this recently and it finally worked!...

On windows I use "Agent Ransack" to do my searching, very useful.

 

Hi，guys. I met the same issues after I followed the share instruction of the offical Karting Micro Game. I have tried deleting the headline "using UnityEditor" and relevant codeline, but it still can't work. Is there any other idea to solve this question?

 

Thx for info. I will try it.~~~

 

I met the same issues but I already solved it. it's not a problem about "UNITY_EDITOR" in my case I delete (Handles.Label in OnDrawGizmos) "Handles.Label" it's custom 3D GUI controls and drawing in the scene view. I make text in scene view.

 

you need to ifdef the entire onDrawGizmos() method

 

Apparently there is another cause to this issue. If you are inheriting from another script that is using UnityEngine, Visual Studio will tell you that the

using UnityEngine

directive is unnecessary. This may normally be true, except if you happen to be using

#if !Unity_Editor

in your script. Everything up to

#endif

that is part of UnityEngine is seen as not existing.
A small example:

Code (CSharp):

1. #if !UNITY_EDITOR
2.         if(Input.GetKeyDown(KeyCode.Escape))
3.         {
4.             Application.Quit();
5.         }
6. #endif

Without

using UnityEngine

this code throws errors saying that Input, KeyCode and Application do not exist in the current context and stops the build with the 'cannot build player while editor is importing assets or compiling scripts' message in the build window.

 

Wow, well at least it sounds like their error messages have improved to actually tell you what is the issue.

 

I ran into this issue today. Builds would just stop, if I did it from `Build and Run` I'd just get "cannot build player while the editor is importing...". No errors in the console.

I opened up the editor.log and low and behold, one of my `#if UNITY_EDITOR` defines was consuming a `}`. The moral of the story is to always check the logs! https://docs.unity3d.com/Manual/LogFiles.html

Here's a snippet:

Code (CSharp):

1.  
2. ##### ExitCode
3. 1
4. ##### Output
5. Assets/RowdyRobot/Scripts/Persistence/SerializableScriptableObject.cs(25,2): error CS1513: } expected
