The referenced script on this behaviour game object main camera is missing как исправить

Sometimes when I start my game, I get pointless warnings. I do not know where they come from and I do not have any objects that address a script that does not exist. How can I remove or fix these messages?

Console:

Inspector:

When I right click on the icon of the file in the inspector I get two possible options. Both of them do not work or when I try to click on them nothing happens.

Inspector context menu:

I had this same issue as well. I think it’s caused by deleting the default scene but not changing the «Scenes in Build» in the build settings. Here’s how I fixed it.

1. Go to your build settings (File > Build Settings). There should a greyed out box that says «deleted». This is the (now missing) default scene.
2. Right click on it and remove it
3. Add your current scene

That happens when you’ve changed the C# class name of a script, or you changed the script’s file name in the project, so that they don’t match. In your case, the problem is with whichever script you have highlighted in your Inspector screenshot.

You can remove this un-reachable script from inspector panel and load again as a component. So you can use your script with no problem agin.

If, or when, you first start your project — you move and/or rename the original default scene that was included in the «scenes» folder, Unity will throw an ever-increasing number of these false references until you end up sitting in the park throwing breadcrumbs at yourself. They can get into the thousands.

Here’s how to fix it:

1. Go into «File -> Build Settings» and delete all the «Scenes in
   Build» then exit out of that window.
2. Find that original renamed scene, double click it so it is
   active, and go to «File -> Save As…»
3. Save this scene as a brand new scene with a new name. This is crucial. Don’t simply overwrite the file that is there. For instance, if the current
   file is named «scene_battlefield», rename it to something like
   «scene_battlefield_whatever».
4. Delete the new file («scene_battlefield_whatever») by right-clicking
   on it in the «Assets» panel. However, you’ll notice that the name
   at the top of the screen still says «scene_battlefield_whatever».
5. Go back to «File -> Save As…» again and this time click on the
   original file you had prior to renaming and overwrite it. The name
   at the top of the screen will change as expected (to
   «scene_battlefield»).
6. Go back to «File -> Build Settings», add «scene_battlefield» (or
   whatever it’s called), and build the program to a folder. After the
   build is complete, you can delete the build. This built version of your program is unimportant.
7. Restart Unity and load up the project as usual.

Basically the «Save As…» rewrites over all the old legacy script connections.

If you can’t remember which scene in your game is the original renamed scene, you’ll need to redo the «Save As…» part for each scene. However, you only have to do the «Build Settings» once.

And that’s it. You should never have these random scripts popping up again. Hope that helps.

This usually shows up when you assign a script to an object and then delete the script from your project. If you’re sure that no object in your scene has this script assigned, perhaps some object that gets instantiated at the run time does? Also, check out this page, it might help you find the source of these errors.

File name and public class name should be same like Test.cs so public class should be public class Test

In my case I had used Window->Rendering->Lighting->»Generate Lighting» on a Scene….»Scene1″ for example. Unity3d then created a Scene1 folder inside my Scenes directory parallel to my Scene1 asset.

I later renamed Scene1 to Level1, but the directory Scene1 did not change accordingly. I got these errors until I renamed the lighting folder to Level1 as well.

First click «Add Component» in the Editor.
Add the script named «NameFinder». Open your IDE (Rider, Visual Studio etc.). Fill the class with following lines.

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

public class NameFinder : MonoBehaviour
{
    // Update is called once per frame
    void Update()
    {
        Debug.Log("Name of the object is:" + gameObject.name);
    }
}

Come back to Unity and watch console while in Play mode. Name of your object should be printed each frame. If you can find it in the scene, good. Get out of the play mode and delete it.

If you can not find it in your scene, your scene file is corrupted. Close unity, open your scene file in a text editor, search for the name of your object and delete the object manually.

You may want to see how Unity stores scene objects. In my case I had to search for GUID and delete the stuff that has the same reference. (Transform and other components should be removed.)

Actually, for me it is when I forget to end the game and then start editing the script!

When I save my script and go back into Unity I get this error.

Of course if I remember to end my game before editing this error doesn’t pop up.

In my case this was not due to a missing script in the scene, but inside a Prefab that the scene uses.

Thanks to a post in Unity Forums.

Remove the missing reference from your GameObject. You attached your script to something, remove the now missing component, and done.

Another potential reason why this error might occur is that your script file name and script class name are different. For example:

Исправил, полоска от врага к игроку рисуется, но враг не поворачивается. Движение я пока не ставлю, чтоб не отвлекало. И пишет еще лог предупреждения: The referenced script on this Behaviour is missing!
Вот на всякий случай код:

The referenced script on this Behaviour is missing!

Это редактор пишет в том случае, если потерялась ссылка на скрипт в компоненте одного из объектов. Это происходит если переименовать/удалить скрипт в файловом менеджере, а не в редакторе. Если кликнуть на ошибку, открывается explorer, а не показывается сбойный объект.
Пощелкайте по объектам, у к-х есть скрипты и найдите компонент, у к-го в поле Script вместо имени скрипта написано Missing и снова укажите нужный скрипт. Либо опытным путем определите — какой из объектов в игровом режиме перестал себя вести как раньше.

Спасибо. Думал проблема в самом каком либо скрипте, а оказалось действительно пропал скрипт (при чём я не помню, что это был за скрипт, да и в игре не увидел пропажи).
