I’m new to Godot and I tried to write a tool that creates a Posiotion2D array for my chess tiles. By checking InitTilePositions in the inspector, the CreatePositions() method creates 64 Posiotion2D nodes that appear in the scene tree. The problem is that the tilesPositions array stays with empty Posiotion2D nodes even after CreatePositions() was activated. Would love some help!

public class TilesPositions: Node2D
{
#region FIELDS
[Export] public float SpaceBetween { get; set; } = 50;
[Export] public float YCorrection { get; set; }
[Export] public float XCorrection { get; set; }
[Export] public bool InitTilePositions { get; set; }
[Export] Position2D[] tilesPositions = new Position2D[64];
private const int ROWS = 8;
private const int COLUMNS = 8;
