static List<string> m_listPath = new List<string>();
    
        public static string GetChildPath(Transform trans, string childName)
        { 
            m_listPath.Clear();
            FindChildGameObject(trans.gameObject, childName);
            string path = "";
            for (int i = 1; i < m_listPath.Count; i++)
            { 
                path += m_listPath[i];
                if (i != m_listPath.Count-1)
                    path += "/";
            }
            return path;
        }
    
        
        public static GameObject FindChildGameObject(GameObject parent, string childName)
        { 
            m_listPath.Add(parent.name);
            if (parent.name == childName)
            { 
                
                return parent;
            }
            if (parent.transform.childCount < 1)
            { 
                return null;
            }
            GameObject obj = null;
            for (int i = 0; i < parent.transform.childCount; i++)
            { 
                GameObject go = parent.transform.GetChild(i).gameObject;
                obj = FindChildGameObject(go, childName);
                if (obj != null)
                { 
                    
                    break;
                }
            }
            
            return obj;
        }

如何使用

using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class TestFindChild : MonoBehaviour
    { 
        public Transform m_par;
        public string m_childName;
        // Start is called before the first frame update
        void Start()
        { 
            string path = PublicFunc.GetChildPath(m_par, m_childName);
            Debug.Log(path);
        }
    
        // Update is called once per frame
        void Update()
        { 
            
        }
    }
