其中值得注意的是 luaL_doCallBackFromCBIdx 函數，其用來回呼 Lua Callback Function。function dispResult(num) msg(num) end tellMeNum(dispResult)此 lua script 呼叫 tellMeNum 並將 dispResult 以參數傳給 C#，待 C# 呼叫 dispResult，dispResult 接收到 num 之後呼叫 msg 使 num 顯示在 Unity Console。

其中的 int nArrsz 為字串數目，IntPtr pStringArray 為字串陣列 ( 對應至 C 的 char** ) ，string[] data 是轉型後的資料。

選擇的檔案除了 Prefab/GameObject 之外，Lightmap 圖片也要選擇：
Listarrld = new List (); LightmapData ld = new LightmapData(); ld.lightmapFar = aa.assetBundle.Load("LightmapFar-0", typeof(Texture2D)) as Texture2D; ld.lightmapNear = aa.assetBundle.Load("LightmapNear-0", typeof(Texture2D)) as Texture2D; arrld.Add(ld); LightmapSettings.lightmapsMode = LightmapsMode.Dual; LightmapSettings.lightmaps = arrld.ToArray();
GameObject go = GameObject.Instantiate(aa.assetBundle.Load("StaticObj", typeof(GameObject))) as GameObject;
此外慶幸的是，GameObject 之 MeshRenderer 內有關 Lightmapping 之參數在存取 AssetBundle 時皆有自動設定，不需再額外寫程式存取設定之。
