Typesafe instance, adressing subnodes without the knowledge of their path

Firstly, hi everyone :). I’m mainly working in Unigine, but I’m trying to toy with Godot and this is the first issue that I was unable to solve via the docs and google-fu :(. I am using c#, but I welcome the solution in all supported languages :).

So I basically just want to add “my object” to the scene, connect to its parameters, maybe flip character, maybe register to “area” volume, maybe whatever else, but I want to do it with object/interface type safety, basically. So that when I rename “area”, or change its tree structure, it won’t break everywhere…

See here

I am familiar with the UE4 and UNIGINE and both could easily work with “spawned” actors/nodes, but I am unable to find the right way in Godot. Am I doing it inherently wrong?

The testing idea now was to have a tile for an endless runner. I need to spawn these “forever”, so I need to work with three tiles and every time the player crosses from the second tile to the third tile, I need to drop the first tile, create the “fourth” tile and move everything a tile back (so that I don’t run out of coordinates, etc). Pretty standard, easy stuff.

My instincts are to have some tile handler that spawns and despawns the tiles and communicates only with what he needs.

That question was a moment of weakness of me, because the solution could not be simpler. I don’t like querying with strings and I was so focused on that, that I did NOT see the obvious choice: query with string once, in the constructor of the Chunk scene and store the result for the usage in the world…

public class Chunk : Node {
    // this will stay the same
    public Area myArea;
    public override void _Ready() {
        // even if I'll have to change the path here
        myArea = GetNodeOrNull<Area>("CollisionShape/Area");

and then simply do this:

public class World : Spatial {
public override void _Ready() {
	var chunk = ResourceLoader
    var thatChunkArea = chunk.myArea;

So yeah, really stupid question, shoutout to kleonc for helping me on reddit.
