How to restart multiple level to result in a whole game restart? Godot 4.0

Question

I made a 2D rpg game. This main node starts as the title screen which changes the scene to level 1 upon pressing start.

In summary there are three levels that the player goes through. When the player dies and goes to the main menu, I want all the changes of the levels the player went through to be reset. Restarting the values of Globals/Singletons are not issue, however, the changes within each levels need to be reset.

For example things move to a different position based on conditions.

I am thinking of resetting manually, but I was wondering if anyone has any recommendations or insights on other ways to do it.

Answer 1

When a level is loaded and before any changes happen to it, save it as a packed scene.
You can use this scene next time the player dies and has to restart the level.
Here is how you save a scene as a packed scene:

var packed_scene = PackedScene.new()
packed_scene.pack(get_tree().get_current_scene())
ResourceSaver.save("res://my_packed_scene.tscn", packed_scene)

It works thank you!

Also anyone else using Godot 4 they switched it backwards with ResourceSaver.
It is this instead

var packedscene = PackedScene.new()
packedscene.pack(gettree().getcurrentscene())
ResourceSaver.save(packedscene,"res://mypackedscene.tscn")
