資源打包腳本，放到Assets\Editor 文件夾下

using UnityEngine; using System.Collections; using UnityEditor; using System.IO;public class assetPack : Editor {/* [MenuItem("Custom Editor/Build AssetBundle From Selection - Track dependencies")] static void ExportResource2() {// Bring up save panelstring path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0){// Build the resource file from the active selection.Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path,BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);Selection.objects = selection;} }* */ /* [MenuItem("Custom Editor/Build AssetBundle Complited to bytes")] static void ExportResource5() {// Bring up save panelstring path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0){// Build the resource file from the active selection.Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path,BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets, BuildTarget.StandaloneWindows);Selection.objects = selection;FileStream fs = new FileStream(path, FileMode.Open, FileAccess.ReadWrite);byte[] buff = new byte[fs.Length];fs.Read(buff, 0, (int)fs.Length);string password = "shanghaichaolan";packXor(buff,buff.Length,password);Debug.Log("filelength:"+ buff.Length);fs.Close();File.Delete(path);string BinPath = path.Substring(0, path.LastIndexOf('.')) + ".bytes";FileStream cfs = new FileStream(BinPath,FileMode.Create);cfs.Write(buff, 0, buff.Length);Debug.Log("filelength:" + buff.Length);buff = null;cfs.Close();} }*/[MenuItem("Custom Editor/Save Scene2")] static void ExportResource() {// Bring up save panelstring path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0){// Build the resource file from the active selection.Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path,BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);Selection.objects = selection;} }[MenuItem("Custom Editor/Make unity3d file to bytes file")] static void ExportResourceNoTrackSS() {string path = EditorUtility.SaveFilePanel("Save Resource", "", "New Resource", "unity3d");if (path.Length != 0){FileStream fs = new FileStream(path, FileMode.Open, FileAccess.ReadWrite);byte[] buff = new byte[fs.Length];fs.Read(buff, 0, (int)fs.Length);string password = "shanghaichaolan";packXor(buff, buff.Length, password);Debug.Log("filelength:" + buff.Length);fs.Close();File.Delete(path);string BinPath = path.Substring(0, path.LastIndexOf('.')) + ".bytes";FileStream cfs = new FileStream(BinPath, FileMode.Create);cfs.Write(buff, 0, buff.Length);Debug.Log("filelength:" + buff.Length);buff = null;cfs.Close();} }static void packXor(byte[] _data, int _len, string _pstr) {int length = _len;int strCount = 0;for (int i = 0; i < length; ++i){if (strCount >= _pstr.Length)strCount = 0;_data[i] ^= (byte)_pstr[strCount++];}}}

?菜單上就會出現兩個， 把要打包的資源做成Prefab，選中資源，然后菜單Custom Editor/Save Scene2? 輸入名字

新生成的文件，再選中新生成的文件，點擊菜單Custom Editor/Make unity3d file to bytes file?? 輸入名字

又生成了一個文件，再點擊這個文件，菜單Custom Editor/Save Scene2? ，這樣就打包加密好了

using UnityEngine; using System.Collections;public class loadnew : MonoBehaviour {public string filename;private string BundleURL;private string AssetName;void Start(){//StartCoroutine(loadScenee());StartCoroutine(LoadResource());}IEnumerator loadScenee(){string path;path = "file://" + Application.dataPath + "/" + filename + ".unity3d";Debug.Log(path);WWW www = new WWW(path);yield return www;AssetBundle bundle = www.assetBundle;//GameObject go = bundle.Load("gCube",typeof(GameObject)) as GameObject;GameObject ObjScene = Instantiate(www.assetBundle.mainAsset) as GameObject;bundle.Unload(false);}IEnumerator LoadResource(){BundleURL = "file://" + Application.dataPath + "/" + filename + ".unity3d";Debug.Log("path:" + BundleURL);WWW m_Download = new WWW(BundleURL);yield return m_Download;if (m_Download.error != null){// Debug.LogError(m_Download.error);Debug.LogError("Warning errow: " + "NewScene");yield break;}TextAsset txt = m_Download.assetBundle.Load(filename, typeof(TextAsset)) as TextAsset;byte[] data = txt.bytes;byte[] decryptedData = Decryption(data);Debug.Log("decryptedData length:" + decryptedData.Length);StartCoroutine(LoadBundle(decryptedData));}IEnumerator LoadBundle(byte[] decryptedData){AssetBundleCreateRequest acr = AssetBundle.CreateFromMemory(decryptedData);yield return acr;AssetBundle bundle = acr.assetBundle;Instantiate(bundle.mainAsset);}byte[] Decryption(byte[] data){byte[] tmp = new byte[data.Length];for (int i = 0; i < data.Length; i++){tmp[i] = data[i];}// shanghaichaolanstring password ="shanghaichaolan";packXor(tmp,tmp.Length,password);return tmp;}static void packXor(byte[] _data, int _len, string _pstr){int length = _len;int strCount = 0;for (int i = 0; i < length; ++i){if (strCount >= _pstr.Length)strCount = 0;_data[i] ^= (byte)_pstr[strCount++];}}void update(){} }

?加載加密和不加密的資源
