功能说明：

使用最大化骨骼的时候需要添加动骨，但是对于不同的时装每个动骨组件要有不同的数据，因此希望将所有动骨的数据序列化存储到lua文件夹中，可读性好，使用xlua也易于解析，之后如果想要在原有参数上做调整，只需要将数据文件再导入或者直接修改lua文件中的某个参数即可；

InspectorUI扩展：

首先是写了一个InspectorUI的扩展，一个存储按钮和一个解析按钮；

    public override void OnInspectorGUI(){DrawButtons();base.OnInspectorGUI();}private void DrawButtons(){if (GUILayout.Button("Export LuaConfig")){Serialized();}if (GUILayout.Button("Import LuaConfig")){Parse();}}

存储到lua文件：

导出lua时可能会遇到各种报错，这里先提供一个枚举表示各种结果，然后写一个弹框接口来显示结果；

    public enum EExportRetType {success = 0,wrongGameObject = 1,noDBCom = 2,};private void ShowExportMessageBox(EExportRetType ret){switch (ret){case EExportRetType.success :EditorUtility.DisplayDialog("导出配置文件", "大吉大利，今晚吃鸡", "确定");break;case EExportRetType.wrongGameObject :EditorUtility.DisplayDialog("导出配置文件", "请选择Bip001或head_guadian骨骼进行导出", "确定");break;case EExportRetType.noDBCom :EditorUtility.DisplayDialog("导出配置文件", "当前导出骨骼下没有动骨组件", "确定");break;}}

 要存储骨骼下所有的动骨数据，我们需要拿到所有的动骨组件，然后拿到每一个动骨数据；这里我们使用动骨的游戏对象名作为key，每个key对应它所有的数据；接下来问题就变成了如何序列化一个动骨组件的数据，先简化思考一下：如果仅仅是存储一个int数据呢，这应该是很简单的，拿到动骨组件，拿到这个数据，用这个字段名作为key，然后拿到它的值存储起来即可，其它基本数据类型也是如此，而一些自定义的类其实就是这些数据的组合，包括Unity定义的一些类，在DynamicBone里有一个AnimationCurve，它的组成粒度都是一些基本数据类型，明白这一点就可以对各种数据做一些分别处理，这里我使用一个FormatToLua来重载存储各种数据类型；

需要注意的一些语法细节点：

• bool转换成string时，true会变为True，所以这里要使用ToLower()；
• 枚举值使用int进行存储，转换时使用(int)强转即可；
• 在string.Format中，{}属于特殊字符，如果要打印，需要使用"{{}}"，也就是要double；

    private string FormatToLua(string key, string val){return string.Format("        {0} = '{1}',\n", key, val);}private string FormatToLua(string key, bool val){return string.Format("        {0} = {1},\n", key, val.ToString().ToLower());}private string FormatToLua(string key, float val){return string.Format("        {0} = {1},\n", key, val);}private string FormatToLua(string key, int val){return string.Format("        {0} = {1},\n", key, val);}private string FormatToLua(string key, Vector3 val){return FormatToLua(key, val.x, val.y, val.z);}private string FormatToLua(string key, params string[] val){var valueStr = "{";for(int i = 0; i < val.Length; i++){valueStr += string.Format("'{0}'", val[i]);if (i != val.Length - 1){valueStr += ", ";}else{valueStr += "}";}}return string.Format("        {0} = {1},\n", key, valueStr);}private string FormatToLua(string key, params float[] val){var valueStr = "{";for(int i = 0; i < val.Length; i++){valueStr += val[i];if (i != val.Length - 1){valueStr += ", ";}else{valueStr += "}";}}return string.Format("        {0} = {1},\n", key, valueStr);}private string FormatToLua(string key, AnimationCurve curve){var valueStr = "{\n";var keys = curve.keys;for(int i = 0; i < keys.Length; i++){valueStr += FormatToLua((i + 1).ToString(), keys[i]);}valueStr += "        }";return string.Format("        {0} = {1},\n", key, valueStr);}private string FormatToLua(string key, Keyframe kf){var valueStr = "{\n";var fmtStr = "        ";valueStr += fmtStr + FormatToLua("time", kf.time);valueStr += fmtStr + FormatToLua("value", kf.value);valueStr += fmtStr + FormatToLua("inTangent", kf.inTangent);valueStr += fmtStr + FormatToLua("inWeight", kf.inWeight);valueStr += fmtStr + FormatToLua("outTangent", kf.outTangent);valueStr += fmtStr + FormatToLua("outWeight", kf.outWeight);valueStr += fmtStr + FormatToLua("weightedMode", (int)kf.weightedMode);valueStr += fmtStr + "    }";return string.Format("            [{0}] = {1},\n", key, valueStr);}

然后就可以将组件的数据存储到一个字符串内了，如下所示，本来想用反射，但是反射得到的对象值都是object类型；然后写入到lua文件中即可；

    private string SerializedSingleCom(DynamicBone dbCom){string content = "";content += string.Format("    ['{0}'] = {{\n", dbCom.name);// foreach(var fieldInfo in typeDB.GetFields(BindingFlags.Public | BindingFlags.Instance)){//     string name = fieldInfo.Name;//     var value = fieldInfo.GetValue(dbCom);//     var fieldTypeStr = fieldInfo.FieldType.ToString();//     Type fieldType = fieldInfo.FieldType.AsType();//     if (!CheckIsInBlackList(fieldTypeStr) && value != null){//         sw.WriteLine(FormatToLua(name, value as fieldType));//     }// }content += FormatToLua("lodToggle", dbCom.lodToggle);content += FormatToLua("m_Root", dbCom.m_Root.name);content += FormatToLua("m_UpdateRate", dbCom.m_UpdateRate);content += FormatToLua("m_Damping", dbCom.m_Damping);content += FormatToLua("m_Elasticity", dbCom.m_Elasticity);content += FormatToLua("m_Stiffness", dbCom.m_Stiffness);content += FormatToLua("m_Inert", dbCom.m_Inert);content += FormatToLua("m_Radius", dbCom.m_Radius);content += FormatToLua("m_EndLength", dbCom.m_EndLength);content += FormatToLua("m_DistantDisable", dbCom.m_DistantDisable);content += FormatToLua("m_DistanceToObject", dbCom.m_DistanceToObject);content += FormatToLua("m_FreezeAxis", (int)dbCom.m_FreezeAxis);content += FormatToLua("m_EndOffset", dbCom.m_EndOffset);content += FormatToLua("m_Gravity", dbCom.m_Gravity);content += FormatToLua("m_Force", dbCom.m_Force);content += FormatToLua("m_DampingDistrib", dbCom.m_DampingDistrib);content += FormatToLua("m_ElasticityDistrib", dbCom.m_ElasticityDistrib);content += FormatToLua("m_StiffnessDistrib", dbCom.m_StiffnessDistrib);content += FormatToLua("m_InertDistrib", dbCom.m_InertDistrib);content += FormatToLua("m_RadiusDistrib", dbCom.m_RadiusDistrib);content += "    },\n";return content;}

从lua文件中恢复动骨组件数据：

恢复动骨数据很简单，只要解决一个问题，如何从lua文件中取出想要的数据；这里只讲述这个问题的思路，首先将lua文件加载出来，得到一个LuaTable，然后使用这个table来取数据；得到table以后，我们可以使用table.GetKeys()，它返回一个迭代器，我们可以得到所有的key-val，拿到每个组件的数据，

        LuaEnv luaEnv = new LuaEnv();luaEnv.AddLoader(CustomLoader);string luaPath = string.Format("{0}.lua", path);object[] objs = luaEnv.DoString("return require('Common.ActorBone.4000002_DB')");LuaTable table = objs[0] as LuaTable;foreach (var item in table.GetKeys()){var tb = table.Get<LuaTable>(item);var ret = ParseSingleDBCom(item.ToString(), tb);if (!ret){return;}}

在LuaTable类中提供了这样一个接口，用于拿到table中的数据，无论是数组段table还是hash段table都可以，我们可以一层层获取到所有数据，然后使用组件的实例化函数来完成所有的赋值操作：

        public TValue Get<TValue>(string key){TValue ret;Get(key, out ret);return ret;}tb.Get<float>(1)tb.Get<bool>("inTangent")tb.Get<LuaTable>(i)
