Unity如何处理lua热重载

using UnityEngine;
using UnityEditor;
public class LuaFastProcessor : AssetPostprocessor
{
    protected const string HOT_FIX_STR = "HU.Update()";
    public static void OnPostprocessAllAssets(string[] importedAsset, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths)
    {
        if (Application.isPlaying)
        {
            string path = Application.dataPath + "\\StreamingAssets\\scripts\\hotupdatelist.lua";
            StringBuilder sb = new StringBuilder();
            sb.Append("local FileNameList = {\n");
            for (int i = 0; i < importedAsset.Length; i++)
            {
                bool isLuaFile = importedAsset[i].EndsWith(".lua");
                if (isLuaFile)
                {
                    if (XLuaManager.Instance.LuaEnvIns != null)
                    {
                        sb.Append("\"");
                        string strName = importedAsset[i].Replace(".lua", "");
                        strName = strName.Substring(strName.LastIndexOf("/") + 1);
                        Debug.LogError(strName);
                        sb.Append(strName);
                        sb.Append("\",");
                    }
                }
            }

            sb.Append(@"
                    }
                    return FileNameList");
            File.WriteAllText(path,sb.ToString());
            if(XLuaManager.Instance.LuaEnvIns!=null)
                XLuaManager.Instance.LuaEnvIns.DoString(string.Format(HOT_FIX_STR));
        }
    }
