正如标题所描述的，我目前遇到了一个问题，“Physics.OverlapSphere”没有将任何东西放入数组。我觉得这好像是一个非常简单的错误，但我找不到。
下面是我写的代码，我所期望的是当玩家进入Phyhsics.OverlapSphere的半径范围内时，它会添加到数组中，然后触发其余的检查。

public class EnemyFieldOfView : MonoBehaviour
{
    public float efovRadius = 4f;
    [Range(0, 360)]
    public float efovAngle = 45f;

    public GameObject playerSprite;
    public bool alerted;

    public LayerMask playerMask;
    public LayerMask objectMask;

    public Collider[] playerSearch;

    public void Start()
    {
        StartCoroutine(searchRoutine());
    }

    public IEnumerator searchRoutine()
    {
        WaitForSeconds wait = new WaitForSeconds(0.25f);

        while (true)
        {
            yield return wait;
            Searching();
        }
    }

    public void Searching()
    {
        playerSearch = Physics.OverlapSphere(transform.position, efovRadius, playerMask);
        if (playerSearch.Length != 0)
        {
            Transform enemyTarget = playerSearch[0].transform;
            Vector2 targetDirection = (enemyTarget.position - transform.position).normalized;

            Debug.Log("In fov circle");

            if (Vector3.Angle(enemySprite.transform.up, targetDirection) < efovAngle / 2)
            {
                float distanceBetween = Vector3.Distance(transform.position, enemyTarget.position); 
                if (!Physics.Raycast(transform.position, targetDirection, distanceBetween, objectMask))
                {
                    Debug.Log("Alerted");
                    alerted = true;
                }
                else
                {
                    alerted = false;
                }
            }
            else
            {
                alerted = false;
            }
        }
        if (alerted == true)
        {
            alerted = false;
        }
    }
