Missing reference after reloading a scene : but the referencing object still exist !!!

Hi guys,

After reloading a scene I have an error when one of my script tries to call a method on a public property it has which is another script inside another game object in the scene. This public property is set by simply drag & drop the game object which contains the target script directly in the editor.


I reload the scene like this : SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex,LoadSceneMode.Single);

When the error occurs I can see that :
- the public property it's not null, it's still references the script in the game object in the scene
- the game object in the scene still exists and the targeting script too

The error message is :
MissingReferenceException: The object of type 'Rules' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

I do not manually destroy the reference neither the game object which contains the targeting script. Moreover, when I reload the scene I expect everything to get back to their default state and for what I can see it's the case. So I don't understand why I've got this error.

Any help is welcomed

Thanks

 

Are you unsubscribing from all global events? Are you passing references of scene objects to scriptable objects/any other .asset file? Do you have any singletons which are not set to "DontDestroyOnLoad"?

 

Hi,

You're right - I just noticed that I didn't unsubscribe to some global events that are store in a static class - that was the cause of the error.

Thanks.

 

This saved me.

Thanks A.Killingbeck, you saved me a lot of time

 

I encountered this problem.But I can't fix it.Can you help me?

 

To anyone who might also have this issue check this answer. The anomalies you're experiencing are probably coming from events referencing the old version of an object. Make sure events are loaded

ThisEvent += ThisEvent_Fire

in

OnEnable()

preferably and unloaded

ThisEvent -= ThisEvent_Fire

in

OnDisable()

 

This saved me. Thank you!
