What is the reason of this error?

Assertion failed on expression: 'm_CurrentHiddenGameObjects->find(gameObject.GetInstanceID()) == m_CurrentHiddenGameObjects->end()'


As described in error log, It is refers to "DontDestroyOnLoad" function. But I cannot find any helpful imformation about this . What is error mean?

 

I'd be interested in the same. Happened to me after upgrading from Unity 2017.x to 2019.1. Still looking for a way to get rid of this.

 

I had the same error. Seems to be linked to the fact that my object was hidden in the SceneVis tool. Error disappeared when I changes the visibility to show it again.

 

Thanks! Problem solved after changing the object to visible.

 

What is the SceneVis tool ? Is it some third-party tool?

Thanks. I get it

 

This works for me:

Code (CSharp):

1. private void Awake()
2. {
3. #if UNITY_EDITOR
4.     if (Application.isPlaying)
5.         UnityEditor.SceneVisibilityManager.instance.Show(gameObject, false);
6. #endif
7.     DontDestroyOnLoad(gameObject);
8. }

 

this fixed the problem for me! thank you

 

The console was being spammed with this error for me as well every time I'd enter Play Mode. Deleting the Library folder then reopening the project solved it. 2022.2.0b3, Windows 10.
