Making the player position coherent based on which door he got in

So i'm making a dungeon crawler with rooms generated in a procedural manner - each room has its directions, and when the player enters one of the doors, i want it to come out from the door he actually used. How should i approach that? I would love a thorough explanation on how to approach this, instead of "just" code. Helps me think and reason by myself :D i'll link the scripts i'm using down below :

Rooms:

 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.Tilemaps;
 
 public class Room
 {
     public Vector2Int roomCoordinate;
     public Dictionary<string, Room> neighbors;
     
 
     public Room (int xCoordinate, int yCoordinate)
     {
         this.roomCoordinate = new Vector2Int(xCoordinate, yCoordinate);
         this.neighbors = new Dictionary<string, Room>();
     }
 
     public Room (Vector2Int roomCoordinate)
     {
         this.roomCoordinate = roomCoordinate;
         this.neighbors = new Dictionary<string, Room>();
     }
 
     public List<Vector2Int> NeighborCoordinates ()
     {
         List<Vector2Int> neighborCoordinates = new List<Vector2Int>();
         neighborCoordinates.Add(new Vector2Int(this.roomCoordinate.x, this.roomCoordinate.y - 1));
         neighborCoordinates.Add(new Vector2Int(this.roomCoordinate.x + 1, this.roomCoordinate.y));
         neighborCoordinates.Add(new Vector2Int(this.roomCoordinate.x, this.roomCoordinate.y + 1));
         neighborCoordinates.Add(new Vector2Int(this.roomCoordinate.x - 1, this.roomCoordinate.y));
 
         return neighborCoordinates;
     }
 
     public void Connect (Room neighbor)
     {
         string direction = "";
         if (neighbor.roomCoordinate.y <this.roomCoordinate.y)
         {
             direction = "N";
         }
 
         if (neighbor.roomCoordinate.x > this.roomCoordinate.x)
         {
             direction = "E";
         }
 
         if (neighbor.roomCoordinate.y > this.roomCoordinate.y)
         {
             direction = "S";
         }
 
         if (neighbor.roomCoordinate.x < this.roomCoordinate.x)
         {
             direction = "W";
         }
 
         neighbors.Add(direction, neighbor);
     }
 
     public string PrefabName()
     {
         string name = "Room_";
         foreach (KeyValuePair<string, Room> neighborPair in neighbors)
         {
             name += neighborPair.Key;
         }
 
         return name;
     }
 
     public Room Neighbor(string direction)
     {
         return this.neighbors[direction];
     }
 
 
 
 }


 

Thanks in advance, i'm eager to hear how you would approach this
