Level selector and getting variable value from one scene into another scene

BadSadCoder

Hi I have a problem with setting up my game.

I have this: Level01 (Node): - LevelGrphics - DoorsAndKeys - PlayerNode - Tilemap - etc

Also I have this

LevelSelector(Node2D): - Button(ButtonNode)

LevelSelector have script with variables like SCORE and LIVES

My main scene (that loads after F5) is LevelSelector. When I hit the button on that scene my other scene is loaded (Level01.tscn). It works but I'm not sure if I'm doing it correctly ( get_tree().change_scene("res://levels/Level01.tscn") )

I want Level01.tscn to have access to LevelSelector variables (SCORE, LIVES). How Can I do that? I know how to get variables from different nodes in the same scene. But how to access variables between separate scenes?

If the scenes both exist in the same tree, you can assess them just like getting other nodes. However, if the scene only exists for a moment, meaning between level changes, then you would need to use a Singleton.

So create a scene (a Node) that is only used to store persistent data (like score) and set this as an autoload in the project settings. This creates a Singleton that will be accessible everywhere, even after level changes.

I use playerVars.gd to store all variables :) and autoloaded it :). It works nice :) I needed that, because later I would had tons of code changing. Thank You :)
