Visual studio code для Unity 2D

а
не увидел щяс исправлю принт скрин неудачный
просто

проще так наверное

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Random = UnityEngine.Random;

public class SimpleRandomWalkDungeonGenerator : MonoBehaviour
{
[SerializeField]
protected Vector2Int startPosition = Vector2Int.zero ;

[SerializeField]
private int iterations = 10;
[SerializeField]
public int walkLength = 10;
[SerializeField]
public bool startRandomlyEachIteration = true;

private TilemapVisualizer tilemapVisualizer;

public void RunProceduralGeneration()
{
Hashset<Vector2Int> floorPositions = RunRandomWalk();
tilemapVisualizer.PaimtFloorTiles(floorPositions);
}

protected Hashset<Vector2Int> RunRandomWalk()

{
var currentPosition = startPosition;
Hashset<Vector2Int> floorPositions = new Hashset<Vector2Int>();
for (int i = 0; i < iterations; i++)
{
var path = ProceduralGenerationAlgorithms.Simplerandomwalk(currentPosition, walkLength);
floorPositions.UnionWith(path);
if (startRandomlyEachIteration)
currentposition = floorPositions.ElementAt(Random.Range(0, floorPositions.count));
}
return floorPositions;
}
}

хз скрин нормальный не делает ноут

Assets\scripts\SimpleRandomWalkDungeonGenerator.cs(28,15): error CS0246: The type or namespace name 'Hashset<>' could not be found (are you missing a using directive or an assembly reference?)

собственно 28 строка вот:
protected Hashset<Vector2Int> RunRandomWalk()
{

хз я по тутору иду там он прописан
на сколько я знаю он влияет на видимость
