写一个工具类能够让所有的建筑物体检测地面并且吸附地面

直接上代码

using UnityEditor;
using UnityEngine;
using System.Collections.Generic;
using System.IO;
using OHGame;
using Unity.VisualScripting;

public class OHEditorTool : Editor
{
    [MenuItem("OHGame/Tools/行动区域点落地")]
    private static void GetObjectsWithScript()
    {
        // 在编辑器模式下获取所有SpawnExitGizmos脚本的物体
        SpawnExitGizmos[] objectsWithScript = GameObject.FindObjectsOfType<SpawnExitGizmos>();

        foreach (SpawnExitGizmos obj in objectsWithScript)
        {
            if (obj.IsGround)
            {
                obj.AddComponent<EditorModeUpdate>();
            }
            Debug.Log("Object with SpawnExitGizmos script: " + obj.gameObject.name);
        }
        
    }
    
}

using OHGame;
using UnityEditor;
using UnityEngine;

[ExecuteInEditMode]
public class EditorModeUpdate : MonoBehaviour
{
    [SerializeField] private LayerMask groundLayer = 1;
    private void Update()
    {
        // 在编辑器模式下执行的代码
        SnapObjectToGround();
    }
    
    private void SnapObjectToGround()
    {
        // 从物体下方发射射线，检测地面碰撞
        RaycastHit hit;
        transform.position += new Vector3(0, 1, 0);
        if (Physics.Raycast(new Ray(transform.position , Vector3.down * 20f), out hit, Mathf.Infinity, groundLayer))
        {
            // 将物体位置设置为地面位置
            transform.position = hit.point+new Vector3(0,GetComponent<SpawnExitGizmos>().Cube_Size.y/2f,0);
            //Destroy(transform.GetComponent<EditorModeUpdate>());
            GameObject.DestroyImmediate(this);
        }
    }
    void OnDrawGizmos()
    {
       
        Gizmos.color = Color.red;
        Gizmos.DrawRay(transform.position , Vector3.down * 20f);
        
    }
}
