Solved:

Instead of using PackedScene[ ], use Array<PackedScene>
[Export] public Array<PackedScene> BottomRooms;
[Export] public Array<PackedScene> TopRooms;
[Export] public Array<PackedScene> LeftRooms;
[Export] public Array<PackedScene> RightRooms;
[Export] public PackedScene ClosedRoom;

Trying to implement a Unity tutorial to Godot (Random Dungeon Generator) in C#
Help
Hi.

Trying to implement this tutorial to Godot: https://www.youtube.com/watch?v=qAf9axsyijY I have problems.

// ProceduralLevels.cs
// I've tried with Node2D
[Export] public PackedScene[] BottomRooms;
[Export] public PackedScene[] TopRooms;
[Export] public PackedScene[] LeftRooms;
[Export] public PackedScene[] RightRooms;

And

[Export(PropertyHint.Flags, "Top,Left,Right,Bottom")] public int Pos = 0;

ProceduralLevels levels;
uint randNum;
public bool spawned;
SceneTreeTween tween;
public override void _Ready()
{
	GD.Randomize();
	levels = GetTree().Root.FindNode("Levels", true, false).GetNode<ProceduralLevels>("Levels");
	// levels = FindParent("Levels").GetNode<ProceduralLevels>("Levels");
	Spawn();
}

public override void _Process(float delta)
{
	DetectRooms();
}

public void Spawn()
{
	if (!spawned)
	{
		GD.Print("Spawn");
		if (Pos == 0)
		{
			randNum = GD.Randi() % (uint)levels.BottomRooms.Length;
			GD.Print("Spawn::Bottom: ", randNum);
			AddChild(levels.BottomRooms[randNum].Instance());
		}
		else if (Pos == 1)
		{
			randNum = GD.Randi() % (uint)levels.TopRooms.Length;
			GD.Print("Spawn::Top: ", randNum);
			AddChild(levels.TopRooms[randNum].Instance());
		}
		else if (Pos == 4)
		{
			randNum = GD.Randi() % (uint)levels.LeftRooms.Length;
			GD.Print("Spawn::Left: ", randNum);
			AddChild(levels.LeftRooms[randNum].Instance());
		}
		else if (Pos == 8)
		{
			randNum = GD.Randi() % (uint)levels.RightRooms.Length;
			GD.Print("Spawn::Right: ", randNum);
			AddChild(levels.RightRooms[randNum].Instance());
		}
		spawned = true;
	}
}

void DetectRooms()
{
	if (GetOverlappingAreas().Count == 0) return;
	foreach (Area2D item in GetOverlappingAreas())
	{
		if (item.IsInGroup("SpawnPoint"))
		{
			QueueFree();
		}
	}
}

Also, in the Unity tutorial is using Invoke(); How to implement Invoke in Godot C#?

Thank you.
