```

### Example

```csharp
using Gley.PedestrianSystem;
using System.Collections.Generic;
using UnityEngine;


public class Test : MonoBehaviour
{
    // A reference to the pedestrian pool and player assigned in the inspector.
    public PedestrianPool PedestrianPool;
    public Transform Player;

    void Start()
    {
        API.Initialize(Player, 1, PedestrianPool);
    }

    public void SetNewDelegate()
    {
        Delegates.SetSpawnWaypointSelector(MySpawnWaypointSelector);
    }

    public static int MySpawnWaypointSelector(List<Vector2Int> neighbors, Vector3 position, Vector3 direction, PedestrianTypes pedestrianType, bool useWaypointPriority)
    {
        //select a random cell
        Vector2Int selectedNeighbor = neighbors[Random.Range(0, neighbors.Count)];

        //return a random waypoint from that cell
        return GetPossibleWaypoint(selectedNeighbor, pedestrianType, useWaypointPriority);
    }


    // Used for demonstration purposes.
    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Alpha1))
        {
            SetNewDelegate();
