lua脚本 打包与读取

一、打包

　　lua的后缀是不被支持打包进assertbundle的，所以我们一般把 .lua后缀 变为.lua.txt 或者 .lua.bytes 进行打包。

     这里我就直接使用了框架的代码

　　

 1 [MenuItem("Lua/Build Lua without jit", false, 2)] 2     public static void BuildLuaNoJit() 3     { 4         BuildAssetBundleOptions options = BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets | BuildAssetBundleOptions.DeterministicAssetBundle; 5  6         /// 清零掉这个 目录下的 * .bytes 文件 方便重新生成 7         string[] files = Directory.GetFiles("Assets/Lua/Out", "*.lua.bytes"); 8  9         for (int i = 0; i < files.Length; i++)10         {            11             FileUtil.DeleteFileOrDirectory(files[i]);12         }13 14         /// convert files whth *.lua format to .bytes  format15         /// then move to Application.dataPath + "/Lua/Out/"16         files = Directory.GetFiles(Application.dataPath + "/Lua/", "*.lua", SearchOption.TopDirectoryOnly);17 18         for (int i = 0; i < files.Length; i++)19         {20             string fname = Path.GetFileName(files[i]);21             FileUtil.CopyFileOrDirectory(files[i], Application.dataPath + "/Lua/Out/" + fname + ".bytes");22         }23 24         AssetDatabase.Refresh();25 26         //use list to collect files whith *.bytes format 27         files = Directory.GetFiles("Assets/Lua/Out", "*.lua.bytes");28         List<Object> list = new List<Object>();29         for (int i = 0; i < files.Length; i++)30         {31             Object obj = AssetDatabase.LoadMainAssetAtPath(files[i]);32             list.Add(obj);33         }34 35         ///buildpipeline with list 36         if (files.Length > 0)37         {38             string output = string.Format("{0}/Bundle/Lua.unity3d", Application.dataPath);39             BuildPipeline.BuildAssetBundle(null, list.ToArray(), output, options, EditorUserBuildSettings.activeBuildTarget);40             string output1 = string.Format("{0}/{1}/Lua.unity3d", Application.persistentDataPath, GetOS());41             FileUtil.DeleteFileOrDirectory(output1);42             Directory.CreateDirectory(Path.GetDirectoryName(output1));43             FileUtil.CopyFileOrDirectory(output, output1);44             AssetDatabase.Refresh();45         }46 47         UnityEngine.Debug.Log("编译lua文件结束");48     }

 

在框架里我新加了一个myTest.lua 文件

--region NewFile_1.lua--Author : admin--Date   : 2015/1/18--此文件由[BabeLua]插件自动生成print("This is a script from a file")--endregion

 

然后运用脚本进行批处理,可以看到我已经打完完毕进 Lua 的 *.unity3d 包里了。

  

　　

二、读取

　　一般包内的初始资源从streamAssert中 加载 到 persistpath ，然后之后就从服务器更新 等等之类，超出本文的范围。

　　我这里就演示下 使用 www 从streamAsserts 路径读取 这个 assetbundle。

      至于什么要从www，这个适用于全平台

　　

　　

 1 #if UNITY_EDITOR  2    string dbpath = "file://" + Application.streamingAssetsPath + "/" + dbfilename 3 //or string path = "file://" + Application.dataPath + "/StreamingAssets" + "/" + "dbfilename";  4 #elif UNITY_IPHONE 5    string dbpath  = "file://" + Application.streamingAssetsPath + "/" + "dbfilename";  6  //or string path = "file://" + Application.dataPath + "/Raw" + "/" + dbfilename";  7 #elif UNITY_ANDROID 8    string dbpath  = Application.streamingAssetsPath + "/" + dbfilename; 9  //or string path = "jar:file://" + Application.dataPath + "!/assets/" + "/dbfilename"; 10 #endif

 

     

      

 1 using UnityEngine; 2 using System.Collections; 3 using LuaInterface; 4  5 public class Test : MonoBehaviour 6 { 7     void OnGUI() 8     { 9         if (GUI.Button(new Rect(10, 10, 150, 100), "TestRead"))   StartCoroutine(TestRead());10 11         if (GUI.Button(new Rect(10, 200, 150, 100), "TestRead2")) TestRead2();12     }13 14 15     IEnumerator TestRead()16     {17         Debug.Log("TestRead");18 19         string path = "file://" + Application.streamingAssetsPath + "/Lua.unity3d";20 21         WWW www = new WWW(path);22 23         yield return www;24 25         Debug.Log("load finish");26 27         AssetBundle bundle = www.assetBundle;28 29         TextAsset text = bundle.Load("myTest.lua") as TextAsset;30 31 32         if(text != null){33             LuaState lu = new LuaState();34             lu.DoString(text.text);35         }36         else{37             Debug.LogError("text == null");38         }39     }40 41 42     public TextAsset tmp; //reference  myTest.lua43 44     void TestRead2()45     {46         Debug.Log("TestRead2");47 48         LuaState lu = new LuaState();49 50         lu.DoString(tmp.text);51     }52 }

如下结果，我们成功实现了从assertbundle读取脚本

 

问题：

　　这里不知道为什么，你点击TestRead 之后 再点一次会报个错误。

 

The asset bundle 'file://C:/Users/admin/Desktop/HotUpdate/CsToLua-master/CsToLua-master/tolua/Assets/StreamingAssets/Lua.unity3d' can't be loaded because another asset bundle with the same files are already loaded

　　

原因如下：http://docs.unity3d.com/Manual/keepingtrackofloadedassetbundles.html
