룸 노드 전체 선택

콘텍스트 메뉴에서 룸 노드를 모두 동시에 선택할 수 있는 메뉴 버튼을 추가해보자.

RoomNodeGraphEditor.cs

/// <summary>
/// Show the context menu
/// </summary>
private void ShowContextMenu(Vector2 mousePosition)
{
    GenericMenu menu = new GenericMenu();

    menu.AddItem(new GUIContent("Create Room Node "), false, CreateRoomNode, mousePosition);
    menu.AddSeparator("");
    menu.AddItem(new GUIContent("Select All Room Nodes"), false, SelectAllRoomNodes);

    menu.ShowAsContext();
}

/// <summary>
/// Select all room nodes
/// </summary>
private void SelectAllRoomNodes()
{
    foreach (RoomNodeSO roomnode in currentRoomNodeGraph.roomNodeList)
    {
        roomnode.isSelected = true;
    }
    GUI.changed = true;
}

이제 노드 그래프 편집기에서 우클릭 시 모든 노드 선택하기 버튼이 콘텍스트 메뉴에 추가된 것을 확인할 수 있다.

모든 노드가 선택된 것을 확인할 수 있다.

룸 노드 삭제 기능

룸 노드 그래프 편집기에서 룸 노드, 노드 간의 연결을 삭제할 수 있는 기능을 구현해보자.

RommNodeSO.cs

/// <summary>
/// Remove childID from the node (returns true if the node has been removed, false otherwise)
/// </summary>

    if (childRoomNodeIDList.Contains(childID))
    {
        childRoomNodeIDList.Remove(childID);
        return true;
    }
    return false;
}

    if (parentRoomNodeIDList.Contains(parentID))
    {

        return true;
    }
    return false;

룸 노드를 삭제할 때 삭제 대기자 큐를 만들어서 삭제하는 이유는 삭제 요청이 올 때마다 노드를 모두 삭제해 버리면 노드 간 연결이라던가, 노드 그래프의 노드 리스트와 같은 것들에서 오류가 발생할 수 있기 때문에 일단은 대기자 큐에 넣어놓고 삭제할 수 있는 것들을 삭제하는 방식을 사용한다.
