因?yàn)榻?jīng)常用到，還要到舊項(xiàng)目去找，因此記錄一下：

using UnityEditor;
using UnityEngine;

            Debug.Log(path);
            //輸出結(jié)果為：Assets/測試文件.png
        }
    }

    [MenuItem("Tools/獲取選中文件絕對路徑")]
    public static void GetFileAbsolutePath()
    {
        string[] GUIDs = Selection.assetGUIDs;

        foreach (var guid in GUIDs)
        {
            string path = Application.dataPath.Remove(Application.dataPath.Length - 6) + AssetDatabase.GUIDToAssetPath(guid);

            Debug.Log(path);
            ///輸出結(jié)果為：Volumes/Eevee_4TB/ZKCM/Test/Draw/Assets/測試文件.png
        }
    }

    [MenuItem("Tools/遍歷全項(xiàng)目Texture文件相對路徑")]
    public static void TraverseTexturesPath()
    {
        foreach (var guid in AssetDatabase.FindAssets("t:Texture"))//此處Texture類型也可以是Model、Audio之類
        {

            Debug.Log(assetPath);
            //后續(xù)可以用以下加載方式繼續(xù)操作
            //var textureImporter = AssetImporter.GetAtPath(assetPath) as TextureImporter;
        }
    }

    [MenuItem("Tools/遍歷子孫物體", false, 1)]
    static void SelectionObjects()
    {
        GameObject[] selections = Selection.gameObjects;
        foreach (GameObject selection in selections)//遍歷每個選中的物體

            }

            //如果僅遍歷子物體
            //foreach (Transform child in selection.transform)
