By scene scheme I was referring to what nodes you use to make this unified mount. for example, by the "Game" scene I imagine you do with a Node; for "World" scene I imagine it to be a Node2D or 3D, depending on the game. Now for "Mechanics" scene I can not imagine which Node would be used; The same goes for UI ... a Control Node?
I do not know if I'm being clear, but when I think of my separate scenes they have an end in them. For example, a "Player" scene would start with a KninematiBody, which would then go to a Node2D of the Level in question.
Now, if I had to subordinate these two to a superior "World" or "Game" scene, or even a "Player Control", what would be the possibilities? Work with a lot of generic Nodes or is there a more specific way?
