本文介绍了一个Unity编辑器脚本，用于检测项目中未使用的图片资源。该脚本通过遍历指定的图片和预制体文件夹，检查图片是否在任何预制体中被引用，从而找出可能可以清理的冗余图片。

一、策划需要进行资源管理，所以要知道某个文件夹下的图片有没有用到。

二、效果如下：

三、代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System.IO;
using UnityEngine.UI;
public class FindTrashRes : Editor {


	public static string prefabPath  = "Assets/GameData/UI/Prefab";
	public static string texturePath = "";

	[MenuItem("Assets/FindTrashRes(检查未使用的图片)")]
	private static void Check(){
		if (Selection.activeObject != null ) {
			if(Selection.activeObject.GetType () == typeof(DefaultAsset)){
				texturePath = AssetDatabase.GetAssetPath((DefaultAsset)Selection.activeObject);
				CheckTextureForPrefab ();
			}
		}
	}

	private static void CheckTextureForPrefab(){
		string log = "检查  图片文件夹："+texturePath+"\t预制体文件夹："+prefabPath;
		Hashtable texturePathTab = new Hashtable ();
		DirectoryInfo textureDir = new DirectoryInfo(texturePath);
		DirectoryInfo prefabDir = new DirectoryInfo(prefabPath);

		//获取全部图片文件
		FileInfo[] files = textureDir.GetFiles("*.jpg",SearchOption.AllDirectories);
		EditorUtility.DisplayProgressBar ("查找文件夹下所有图片", "", 0);
		for (int i = 0; i < files.Length; i++) {
			string subPath = files [i].FullName.Remove(0,Application.dataPath.Length-6);
			subPath = subPath.Replace ("\\","/");
			texturePathTab.Add (subPath, "");
		}
		files = textureDir.GetFiles("*.png",SearchOption.AllDirectories);
		string tlog = "";
		for (int i = 0; i < files.Length; i++) {
			string subPath = files [i].FullName.Remove(0,Application.dataPath.Length-6);
			subPath = subPath.Replace ("\\","/");
			texturePathTab.Add (subPath, "");
		}

		EditorUtility.DisplayProgressBar ("查找文件夹下所有图片", "", 1);

		//判断是否被使用过
		files = prefabDir.GetFiles("*.prefab",SearchOption.AllDirectories);
		for(int i=0;i<files.Length;i++){
			EditorUtility.DisplayProgressBar ("检查预制体", files[i].Name, i/(float)files.Length);
			string subPath = files [i].FullName.Remove(0,Application.dataPath.Length-6);
			GameObject obj = AssetDatabase.LoadAssetAtPath(subPath, typeof(GameObject)) as GameObject;
			Image[] images = obj.GetComponentsInChildren<Image> ();
			for(int im=0;im<images.Length;im++){
				var texture = images [im].mainTexture;
				if (texture != null) {
					string assetPath = AssetDatabase.GetAssetPath (texture);
					if (texturePathTab.ContainsKey (assetPath)) {
						texturePathTab[assetPath]=subPath.Remove(0,prefabPath.Length+1);
					}
				}
			}
		}
		//合成打印日志
		EditorUtility.DisplayProgressBar ("合成打印日志", "", 0);
		log += "\n未被使用的图片：";
		foreach (string k in texturePathTab.Keys)
		{
			string prefab_path = (string)texturePathTab[k];
			if (string.IsNullOrEmpty (prefab_path)) {
				log += ("\n"+k.Remove(0,texturePath.Length+1));
			}
		}
		log += "\n\n\n被使用过的图片：";
		foreach (string k in texturePathTab.Keys)
		{
			string prefab_path = (string)texturePathTab[k];
			if (!string.IsNullOrEmpty (prefab_path)) {
				log += ("\n图片："+k.Remove(0,texturePath.Length+1)+"\t使用的预制体："+prefab_path);
			}
		}
		EditorUtility.DisplayProgressBar ("合成打印日志", "", 1);
		Debug.Log (log);
		EditorUtility.ClearProgressBar ();
	}
