Godot 4 Scene Manager+ (Source Files/Code)

In the Scene manager 1.1 demo moving up to the dark room works.  But moving left to the next room gives the error :  Attempt to call function 'get_parent' in base 'previously freed' on a null instance.

This occurs in the start_screen.gd file in the _on_level_added method on line 32 just after you check for null on the _loading_screen object.

I hope that helps.

I'm using Godot 4.3 beta 1

Hello gracious developer,

I am a fan of your tutorials and I plan on using this Scene Manager to properly develop some games.

I'm unsure of the best way to contribute to your source code as I ran into an issue. It might be because I am using Godot v4.3 beta2.

Running your example game, when I run through the door immediately to the left I error out with "Attempt to call function 'get_parent_ in base 'previously freed' on a null instance" (gameplay.gd:32 - at function: _on_level_added).

The issue is that when the loading screen is freed the variable _loading_screen becomes "<Freed Object>" and not null. _loading_screen != null is satisfied and that block of code runs even though _loading_screen is intended to be null.

Solution: replace line 31 with `if is_instance_valid(_loading_screen):`

When you run that you will get a similar error again somewhere else and then just repeat the solution. 

I apologize for the essay, but I hope this helps someone.

This is interesting! Can I use this to manage 3D scenes?

Hi there, what is the license for the source code? Could I include snippets in my commercial game?
