룸 노드 연결 유효성 검사

룸 노드가 하나의 부모를 갖고 복도와 방이 정상적으로 연결되도록 여러 유효성 검사를 실시하도록 스크립트를 작성한다.

RoomNodeGraphSO.cs

public class RoomNodeGraphSO : ScriptableObject
{
    /// <summary>
    /// Get room node by room nodeID
    /// </summary>
     public RoomNodeSO GetRoomNode(string roomNodeID)
    {
        if (roomNodeDictionary.TryGetValue(roomNodeID, out RoomNodeSO roomNodeSO))
        {
            return roomNodeSO;
        }
        return null;
    }
}

RoomNodeSO.cs

public class RoomNodeSO : ScriptableObject
{
    public bool IsChildRoomValid(string childID)
    {
        bool isConnectedBossNodeAlready = false;
        // Check if there is there already a connected boss room in the node graph
        foreach (RoomNodeSO roomNode in roomNodeGraph.roomNodeList)
        {
            if (roomNode.roomNodeType.isBossRoom && roomNode.parentRoomNodeIDList.Count > 0)
                isConnectedBossNodeAlready = true;
        }

        // If the child node has a type of boss room and there is already a connected boss room node then return false
        if (roomNodeGraph.GetRoomNode(childID).roomNodeType.isBossRoom && isConnectedBossNodeAlready)
            return false;

        // If the child node has a type of none then return false
        if (roomNodeGraph.GetRoomNode(childID).roomNodeType.isNone)
            return false;

        // If the node already has a child with this child ID return false
        if (childRoomNodeIDList.Contains(childID))
            return false;

        // If this node ID and the child ID are the same return false
        if (id == childID)
            return false;

        // If this childID is already in the parentID list return false
        if (parentRoomNodeIDList.Contains(childID))
            return false;

        // If the child node already has a parent return false
        if (roomNodeGraph.GetRoomNode(childID).parentRoomNodeIDList.Count > 0)
            return false;

        // If child is a corridor and this node is a corridor return false
        if (roomNodeGraph.GetRoomNode(childID).roomNodeType.isCorridor && roomNodeType.isCorridor)
            return false;

        // If child is not a corridor and this node is not a corridor return false
        if (!roomNodeGraph.GetRoomNode(childID).roomNodeType.isCorridor && !roomNodeType.isCorridor)
            return false;

        // If adding a corridor check that this node has < the maximum permitted child corridrs
        if (roomNodeGraph.GetRoomNode(childID).roomNodeType.isCorridor && childRoomNodeIDList.Count >= Settings.maxChildCorridors)
            return false;

        // If the child room is an entrance return false - the entrance must always be the top level parent node
        if (roomNodeGraph.GetRoomNode(childID).roomNodeType.isEntrance)
            return false;

        // If adding a room to a corridor check that this corridor node doesn't already have a room added
        if (!roomNodeGraph.GetRoomNode(childID).roomNodeType.isCorridor && childRoomNodeIDList.Count > 0)
            return false;

        return true;
    }
}

Settings.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public static class Settings
{
    #region ROOM SETTINGS

    public const int maxChildCorridors = 3; // Max number number of child corridors leading from a room - maximum should be 3 although this is not recommended
                                            // since it can cause the dungeon building to fail since the rooms are more likely to not fit togther

    #endregion
}

이제 여러 유효성 검사가 정상적으로 이루어지는지 살펴보자.

입구와 방, 방과 방 사이에는 연결선이 이루어지지 않는다.

복도를 연결하면 정상적으로 선이 연결된다.

하나의 복도에서 세 개 이상의 방으로 이어질 수 없다.

하지만 두 개 이상의 복도로는 연결이 가능하다.

이렇게 여러 유효성 검사가 적용되며 노드 그래프를 생성할 수 있다.
