Unity3d Serialize问题

备忘：

1. ScriptableOjbect中，由于Serialization的原因，不能使用基类引用来存储子类对象，这样都会导致数据丢失

2. 无法直接对Unity的数据如，vector3, quaternion等使用BinaryFormatter进行序列化，会报“SerializationException: Type UnityEngine.Vector3 is not marked as Serializable”。要绕过这个问题的姿势是，自己对Vector3进行包装。下面是其中一种方法

 using System;
 using System.Runtime.Serialization;
 using UnityEngine;

 namespace Assets.Editor
 {
     sealed class Vector3SerializationSurrogate : ISerializationSurrogate
     {

         public void GetObjectData(object obj, System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context)
         {
             Vector3 v3 = (Vector3)obj;
             info.AddValue("x", v3.x);
             info.AddValue("y", v3.y);
             info.AddValue("z", v3.z);
         }

         public object SetObjectData(object obj, System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context, System.Runtime.Serialization.ISurrogateSelector selector)
         {
             Vector3 v3 = (Vector3)obj;
             v3.x = (float)info.GetValue("x", typeof(float));
             v3.y = (float)info.GetValue("y", typeof(float));
             v3.z = (float)info.GetValue("z", typeof(float));

             return (object)v3;
         }
     }
 }

 public static void TestFunc()
         {
             BinaryFormatter bf = new BinaryFormatter();
             SurrogateSelector ss = new SurrogateSelector();

             Vector3SerializationSurrogate v3Surrogate = new Vector3SerializationSurrogate();
             ss.AddSurrogate(typeof(Vector3), new StreamingContext(StreamingContextStates.All), v3Surrogate);

             bf.SurrogateSelector = ss;

             MemoryStream stream = new MemoryStream();

             Vector3 testObj = new Vector3(, , );
             bf.Serialize(stream, testObj);
             stream.Position = ;
             Vector3 resultObj = (Vector3)bf.Deserialize(stream);
             Debug.Log(resultObj);
         }
