Godot v 4.1.1
I’m trying to load in my main game node, as well as my player node as soon as the application begins. The only way currently I can get them to work is if I use call_deferred() on adding them to the root tree as children. However, when I try to use await world.get_tree().create_timer(1.0).timeout after the world and player are added to the root node in the _ready function, I get a nil reference. I know this is because the world and player only get added at the end of the frame because they are deferred to the end of the frame. But I’ve been really confused about how to implement it since I have to instantiate my world nodes in code on application start, or on a new game button click, since I randomly position things.
Essentially I’m trying to figure out what the best solution is for using an autoload singleton to create the main game world on application start. Thanks.
