怎么运行：

lua -> build bundle files no jit

 

容我猜猜：

首先清空当前GetOS()下的streamAssets下面的文件夹

这个是build出来的bundle的目标路径

然后创建一个temp文件夹

吧assets/lua和assets/luaframework/tolua/lua都copy到temp下面

获得temp下面的所有dir

然后对temp/lua下面遍历进行BuildLuaBundle

TODO：这个函数具体实现再看看

 

最后还是用BuildPipeline.BuildAssetBundles打包到streamingAssets/getOs()下面

 

代码节选：

 

 

打出的包在StreamingAssets/GetOs()下面

而lua.unity3d这样的文件就是打出来的包

lua.unity3d.manifest:

我们执行Main.Lua就是在这里执行了

怎么知道DoFile的时候在哪儿找lua?

是通过AddSearchPath接口加的搜索路径

然后DoFile的时候zipMap.TryGetValue(zipName, out zipFile);

 

 

首先是WWW win文件

通过win文件读出menifest

都有哪些bundle

对每一个bundle执行StartCoroutine(CoLoadBundle(name, path));

每一个bundle下载完之后执行：

LuaFileUtils.Instance.AddSearchBundle(name, www.assetBundle);
