Unity - 如何在使用Physics.overlapSphere时不检测自身

Question

我正在制作 3d 塔防游戏，并且我有一个 10x10 的图块，路径将位于该图块上。我目前正在尝试做到这一点，以便当您单击时，游戏会检测到其周围的图块以防止非法路径。然而，它正在检测自己。我该如何解决这个问题？

基本上，我不希望每个图块都检测到自己。代码如下。

路径创建器.cs

using System.Collections;
using System.Collections.Generic;
using Unity.Android.Types;
using UnityEngine;

public class PathCreator : MonoBehaviour
{
    public Mesh StraightPath;
    public Mesh TurnPath;
    public float radius = 5f;
    public static string targetTag = "StraightPath";
    public static bool Message = false;
    public static bool Message2 = false;
    public int pathLayer;
    public Collider myCollider;
    // Start is called before the first frame update
    void Start()
    {
        pathLayer = 7 << LayerMask.NameToLayer("Tile");
        myCollider = GetComponent<Collider>();
    }

    // Update is called once per frame
    void Update()
    {
        Collider[] hitColliders = Physics.OverlapSphere(transform.position, radius, pathLayer);
        foreach (var hitCollider in hitColliders)
        {
            if (hitCollider != myCollider)
            {
                if (hitCollider.gameObject.CompareTag(targetTag))
                {

                    if (!Message2)
                    {
                        Message2 = true;
                        print("Found Me!");
                    }
                }
            }
            else
            {
                if (!Message)
                {
                    print("Found path!");
                    Message = true;
                }
            }
            }
        }
    private void OnMouseDown()
    {
        print("click!");
        gameObject.GetComponent<MeshFilter>().mesh = StraightPath;
        gameObject.tag = "StraightPath";
        Message = false;
        Message2 = false;
    }
}

PathSelect.cs（当前未使用）

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

public class PathSelect : MonoBehaviour
{
    public GameObject StraightPath;
    public GameObject TurnPath;
    public Camera PathChooser;
    public Camera MainCamera;
    // Start is called before the first frame update
    void Start()
    {
        PathChooser.enabled = true;
        MainCamera.enabled = false;
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

这是我当前的代码，我有这些图块。我无法在瓷砖上放置一层，因为它们都需要检测路径何时变成直线路径（参见第二张图片）

我想阻止^^这种情况发生。

我该如何解决这个问题？

您可以跳过正在处理的调用对象，如下所示：

Collider[] hitColliders = Physics.OverlapSphere(transform.position, radius, pathLayer);
foreach (var hitCollider in hitColliders) {
    if (hitCollider.gameObject == gameObject)
        continue;

    // Continue processing stuff
}
