Assigning Scene Objects to DontDestroyOnLoad Object?

Heya folks.

I'm playing around with DontDestroyOnLoad and enabling a component if a particular scene is loaded.

When the component wakes it assigns things like objects that it uses such as cameras and UI elements.

What I've noticed is that however its not referencing the objects within the scene (it has a reference just not the scene specific one) nor can I manually add the objects via inspector to the DontDestroyOnLoad object.

When I try to access something like the Main cam (For closing a menu and switching priorities via a UI button click(). ) it pops an null reference.

Any ideas or am I missing something key about DontDestroyOnLoad objects interactions within scene objects?

Here's the inspector at the Null reference

 

If the objects don't exist in that scene then you won't be able to reference them.
All that DontDestroyOnLoad does it makes the object resident between scenes but it does not make its references resident, they still exist in their original scene. You would need to make them also resident or parent them to this DontDestroyOnLoad object.

 

Would it be possible to make the game manager be a resident of the scene it loads into?

Im having the player make a selection then load the scene with that selection as the choice.

 

I am doing something similar to this using a singleton class that isn't a MonoBehavior but is called by them. You can create another class with public class static variable/functions/properties and values in them are globally available. I also subscribe to the scene change event in that class so that I can handle some things in various scenes even if they don't have a component script related to it.

 

If you need a bunch of GameObjects to stick around that all reference each other, my suggestion is to stop using DontDestroyOnLoad. Make them their own scene, use additive scene loading/unloading, and just don't unload that scene when you switch scenes.
